%name Articles of Interest by Authcom, Nova Scotia\s Internet and Computing Solutions Provider in Kentville, Annapolis Valley

Jimmy Kimmel is the best in the business when it comes to making unsuspecting passersby look like complete morons. On a recent episode of Jimmy Kimmel Live, Kimmel’s crew took to Hollywood Blvd. with Apple’s unreleased iTime smartwatch, first revealed in a patent application earlier this week, to gauge the public reaction. The only problem was that the watch in question was actually a $20 Casio watch with an Apple logo stuck to the back. As you can probably guess, a lot of people didn’t catch on, and the resulting video is pretty hysterical.

Aluminum Yields Weight Drop To Around 1,995 kilograms (4,400 Pounds)

Our new man Greg Migliore is in attendance at a Ford media event at the Blue Oval’s Dearborn, MI headquarters today, and he’s reported in with a handful of the 2015 F-150 stats that we’ve been dying to know. Ford is slow-playing the news release here, but we can still offer up some interesting output and performance figures after half-year of waiting.

We have all be quite aware that Ford’s shift to aluminum construction would save a lot of weight for F-150 models, and the results we’re hearing now are duly impressive. For instance: in Super Crew trim, a 2015 F-150 is a whopping 332 kilos (732 pounds) lighter than was its closest 2014-model-year equivalent. That’s like hauling three middle-aged dudes to your bowling alley’s league night for free. Polish your balls, guys.

Ford isn’t willing to offer up any actual curb weights just yet, but if we take that 332-kilo (732-pound) loss and extrapolate with the 2,326-kilogram (5,128-pound) curb weight of the 2014 F-150 Super Crew with the 3.7-litre V6, we can guesstimate that 2015 models will measure out in the 1,995-kilo (4,400-pound) range. That’s impressive.

We also learned just a bit about the new additions to the engine range. The base engine in the F-150 comes in the form of a naturally aspirated, 3.5-litre V6. That mill may be the little brother of the crew, but it still makes 283 horsepower and 255 pound-feet of torque, giving the 4×2 pickup the a maximum payload of 866 kilograms (1,910 pounds) and a tow rating of 3,447 kilograms (7,600 pounds).

Stepping up one rung on the ladder is the hotly anticipated 2.7-litre EcoBoost V6, turbocharged to the tune of 325 hp and 375 lb-ft of torque. In 4×2 guise, that blown mill allows for maximum payload and towing ratings of 1,020 and 3,855 kilograms (2,250 and 8,500 pounds), respectively.

We’re obviously still excited to learn actual L/100 km ratings and curb weights for the Ford haulers, but in the meantime, you can scroll below to check out the official press release and an official video of the Blue Oval boys putting the EcoBoost F-150 through its towing paces at the Davis Dam in Arizona.

Mock up of the Holley sponsored tower at NCM Motorsports Park

Holley Performance has announced a new partnership with the NCM (National Corvette Museum) Motorsports Park, and is sponsoring the Park’s Control Tower and Event Center in Bowling Green, KY.

“It is only fitting that two great American motorsport brands like Corvette and Holley unite with our sponsorship of the NCM Motorsports Park,” said Trevor Wiggins, Holley VP of Sales. “This track is going to secure Bowling Green’s identity as a motorsports town and we’re proud to be a part of it.”

The two-level Holley Control Tower and Event Center will feature 6,300 square feet on each level (12,600 total in building) including 1,800 square feet of meeting and classroom space, lobby/retail area, restrooms, catering kitchen, reception office, administrative offices, race control room, storage and more. The second level will feature a 2,100 square foot open-air viewing deck, available for private events. A Winners’ Circle Podium is slated for the paddock side of the building, and the overall design of the Holley Control Tower and Event Center mimics that of the Museum.

Holley has been in Bowling Green since 1951, and has been an important part of the Bowling Green economy, currently employing over 250 people at its Russellville Road facility. The company’s industry leading products include electronic fuel injection systems, carburetors, exhaust systems, and many other products for high performance street and racing applications. Holley has powered every NASCAR team since the 1960s with products made in Bowling Green including their current EFI throttle body.

“We have been talking to Holley since we first announced that we were building a Motorsports Park and they were as excited as we were,” said Mitch Wright, General Manager of the NCM Motorsports Park. “Those conversations grew into something bigger and we are thrilled to have them on board.”

Construction on the Holley Control Tower and Event Center is planned for 2015.

Generating Strength – The Cummins ISX Engine

cummins ISX 151 300x284 Articles of Interest by Authcom, Nova Scotia\s Internet and Computing Solutions Provider in Kentville, Annapolis Valley

The Cummins ISX engine is one of the workhorses of the Cummins brand and will continue to be a dominating factor in power generation applications, mining and industrial settings.

Cummins ISX engines are also very popular as a heavy-duty truck application engine.

Blake’s Remanufacturing’s remanufactured Cummins ISX engines are rebuilt to OEM specifications in our ISO 9001 level machine shop. This means that even older model Cummins ISX engine applications are often rebuilt using better, more updated parts and techniques than the original engine. Cummins ISX engines in many aspects replaced the Cummins N14 engines in 2001, due to the EPA tier regulations.

The first Cummins ISX engine rolled off the production line in 1998.

Until 2010, this engine was a dual overhead cam design with one cam actuating the injectors and the other the valve train.

Beginning in 2013, Cummins ISX engines were equipped with on-board diagnostics which monitor emissions output and maximizes engine efficiency.

This Cummins ISX model was also completed one year ahead of production schedule to meet the EPA Department of Transportation Regulations.

The “ISX” in Cummins ISX stands for “Interact System” which is the on-highway fuel system Cummins developed to vastly improve performance. Cummins ISX engines are very popular for on-highway and commercial trucking applications since they have the ability to pull between 430hp – 620hp at 2050 ft./lbs. Consequently, the brother of the Cummins ISX is the Cummins QSX which is part of the “Quantum” series. The Cummins QSX engine is the primary workhorse for off-highway, industrial, marine, heavy equipment and oil & gas applications.

The Cummins QSX delivers between 365hp – 665hp at 1875 ft./lbs. of torque. Blake’s Remanufacturing has the ability to do both Cummins ISX and Cummins QSX engine rebuilds.

These ISX 15 engines, which were being shipped to a customer in Ecuador, have a power range about 450 hp.

Cummins Cooling

The Cummins 15L ISX is the latest engine in the ISX family which ­debuted in 2013.

With the ISX 15 the fuel efficiency is increased 10 percent + over previous models. The foundation of the ISX 15L is the reduction of the size of the radiator and multiple cooling panels.

This reduction in size of the cooling system without the loss of cooling power mean overall better aerodynamics within the engine. The new Cummins ISX engine cooling system allows for losses from the engine’s alternator and various other water pumps to be mitigated. The new technology also allows for more open room which creates cooled air for the engine.

The new cooling technology will likely save around 2,000 gallons of fuel per year for a class 8 truck which also means less particulate emissions. In addition to improved efficiency of the cooling system Cummins has also refined the combustion chamber to provide fewer active re-generations of the after treatment system.

Focus on Fuel Efficiency

The Cummins 15L ISX engine is also the newest engine with the improved fuel system. Up until 2010 the traditional Cummins ISX engine featured the antiquated dual overhead camshaft design.

One of the camshafts activated the injectors and the other camshaft activated the valve train.

This type of injection system is called high pressure injection and operates to create injection pressure by the camshaft actuation.

The dual cam design uses an integrated fuel system model (IFSM) which contains pressure regulators, gear pump, lift pump, metering and timing actuators and shutoff valve to accurately deliver diesel fuel directly to the injectors.

The IFSM typically has a one section valve cover that is either plastic or chrome plated on older models of the Cummins ISX.

The latest versions of the Cummins ISX 15 engine keep getting more fuel-efficient as the technology keeps advancing. Cummins has stated that the newest ISX 15 can deliver up to 2 percent better fuel economy than previously reported. The newest Cummins ISX 15 operational efficiency actually delivers more horsepower than in older ISX engine models.

Engine builders at Blake’s performing line boring on an engine block.

The ratings on the ISX 15 range from 400-600 hp (298-447 kW) with 2050 lb.-ft. of peak torque.

The SmartTorque system Cummins developed adds roughly 200 lb.-ft. of extra torque to the top two gears of the engine.

This means that Class 8 trucks can drive up steeper grades with much fewer downshifts making the ride that much smoother and less strenuous on the engine.

For other models of the Cummins ISX engine, the additional torque from the SmartTorque system is applied to the lower gears where it is needed the most.

Blake’s Remanufacturing reports that it can provide a remanufactured Cummins ISX 15 for half the cost of a new model, with no loss of efficiency or horsepower.

Cummins ISX Fuel Efficiency Physics

The fuel efficiency technology of the Cummins ISX engine uses the power of steam.

Harnessing the power of steam for propulsion purposes has been around for almost 2,000 years. The steam engine was first patented in 1606 by Spanish inventor Jerónimo de Ayanz y Beaumont. It was in 1698 that Thomas Savery patented a steam pump which condensed steam to create a vacuum to draw water into the chamber, then applied the pressurized steam to further a piston.

The same basic steam technology is used today in the Cummins ISX. This scientific process is called the Organic Rankine Cycle.

Applying the Organic Rankine Cycle (ORC) to the diesel engine is quite a different process. Heat in a standard reciprocating engine if often looked as something to be avoided at all costs, but with new technology it is utilized to aid in better fuel efficiency. The technology is called Exhaust Gas Recirculation (EGR) which turns excess heat from a major problem into the key to improved efficiency. In the Cummins ISX engine the heat comes out of the engine and travels directly to a superheater system. The superheater increases the temperature of the wet steam from the boiler into an extremely dry superheated steam.

DSC02973 web 300x168 Articles of Interest by Authcom, Nova Scotia\s Internet and Computing Solutions Provider in Kentville, Annapolis Valley

Engine builder Brad Millers prepping the engine block for assembly.

This concept of “dry steam” is steam that is heated beyond boiling. The dry steam contains a lot of energy which then turns a turbine in power plant systems. The turbine then turns a generator which converts waste heat into electricity. In the Cummins ISX engine the electricity is used to power a small electric motor built into the crankshaft. After the superheated dry steam’s energy is transferred into the turbine it later is sent to a recuperator then to a condenser where it is condensed and routed back into the boiler producing a closed loop system. This is quite a revolutionary concept for the Cummins ISX having both the internal and external combustion in one engine.

The extra energy that is recovered comes from four different sources: 6 percent increase in energy will come from the EGR, 2 percent will come from exhaust energy, and 2 percent will come from other accessories that used to drain additional power. All of this additional energy adds up to about 10 percent increase in overall fuel efficiency for the Cummins ISX 15.

The basic premise of the Cummins ISX engine’s fuel efficiency is recovering waste energy.

Waste energy can be described as energy that is not used for any practical purposes. Energy can be neither created nor destroyed. It is stored in the form of kinetic energy (in motion) or potential energy (stored energy).

When studying energy within the Cummins ISX engine we can ascertain that most of the energy is stored in the diesel fuel as potential energy. When that diesel fuel is burned in the combustion engine it changes form to kinetic energy, which then drives the pistons. However, most of the diesel fuel’s energy is lost as heat.

One gallon of diesel fuel contains about 139,000 Btu (British Thermal Unit) of potential energy.

One Btu is defined as the amount of heat required to increase one pound of water one degree Fahrenheit. The goal with any engine is to achieve peak thermal efficiency where as peak thermal efficiency is described as the work you get divided by the energy you put in.

For example, a gas powered car engine is roughly 25 percent efficient and a heavy-duty diesel powered Cummins ISX engine is roughly 40 percent efficient.

What that means is that if a vehicle used 10 gallons of gas only 4 gallons would go to towards propelling the tires forward; the other 6 gallons are wasted. The Organic Rankine Cycle technology in the Cummins ISX 15 aims to recovery as much energy as possible through heat recovery. Across the board, only roughly 33 percent of energy is used towards moving the motor.

Blake’s also offers new and remanufactured crankshafts, camshafts, lifters, connecting rods, cylinder heads, cylinder blocks and rocker assemblies for all the major diesel manufacturers, including ­Caterpillar, Detroit Diesel, ­Waukesha, John Deere, Mack, Perkins, International/Navistar, Alco, EMD and Komatsu.

An example of waste energy in relation to trucks is when heat escapes from the engine to the outdoors.

The heat sources on a Cummins vehicle that help warm you up on a cold day include the Cummins ISX engine itself, the radiator, transfer case, transmission, differentials, U-Joints, brakes, cooling units, and your heater. Noise is also a heat source and is mostly a waste energy by product.

The second kind of energy is work energy. Work energy is harnessed energy being directed where you want it to go. However, there are always going to be other hindrances to 100 percent thermal efficiency.

Gravity, inertia, laws of aerodynamics and drag will always be barriers to overcome to capturing 100 percent of an energy source.

The second law of thermodynamics states that achieving 100 percent thermal efficiency can’t be accomplished.

ISX Emissions ­History

Cummins has always been on the forefront of emissions reduction and the development of technology that improves emissions output.

The first technology Cummins introduced to help reduce particulate emissions was cooled exhaust gas recirculation or EGR system. This system was introduced in the Cummins ISX CM870 model in 2002 and works by taking exhaust gas and re-circulates it back into the engine intake.

This process radically lowers the combustion chamber temperatures in the Cummins ISX engine thus reducing the creation of Nitrogen Oxide. NOx and NOy (NOx plus other compounds that are created during the oxidation process of NOx) are the common causes of air pollution, smog and acid rain.

Another big change in emissions reduction rolled out in 2008 when Cummins introduced Diesel Particulate Filter technology for the Cummins ISX CM871 model. Diesel Particulate Filter technology or DPF is a filtration system designed to trap particulate NOx matter created by the Cummins ISX engine. The second step of the system is the Diesel Oxidation Catalyst which further breaks down the particulate matter via oxidation of the ash. The ash of the diesel particulate is oftentimes called soot.

Then again in 2010 the Cummins ISX engine made another upgrade to its emissions technology with the ISX 15 CM2250 model.

985 2542 web 300x225 Articles of Interest by Authcom, Nova Scotia\s Internet and Computing Solutions Provider in Kentville, Annapolis Valley

All Blake’s remanufactured exchange engines are dyno tested prior to shipping.

The Cummins ISX 15 CM2250 features the improved Exhaust Gas Recirculation in addition to Selective Catalytic Reduction for diesel particulate matter. These new guidelines further confined to EPA regulations also known as Urea Injection Reduction. The selective catalytic reduction system contains a diesel exhaust fluid composed of urea and water, controller, holding tank, pump, injector and the catalyst brick.

The system works by heating up the diesel exhaust fluid which is then pumped and injected into a decomposition area which then chemically reacts with the diesel exhaust in the Selective Catalytic Reduction chamber to reduce the level of NOx.

The Cummins ISX 15 uses one camshaft compared to previous versions which used two. This single camshaft design in the Cummins ISX engine is due to the introduction of the common rail fueling system in which diesel fuel is pressurized from already high pressure.

The fuel is stored in multiple piston pumps and transferred through tubes to a rail where the diesel fuel is stored under extremely high pressures up to but not including 35,000 psi.

Rebuilding Tips on the ISX

1. Pay special attention to the spring loaded cam gear.

2. Need to use a puller for front and back seal. a. Special puller tool to pull off the crankshaft. b. Kent-Moore Tool.

3. Back off the spring loaded tension before unloading it.

4. Totally non interchangeable between ISX and QSX. Use all specified parts.

5. Difference between ISX engine blocks. a. Some have EGRs and others do not. b. You can use both types of engine blocks if need be: The water fittings just need to be fitted with frost plugs.

6. Everything on ISX and QSX is heavy-duty. These engines use heavy-duty cams.

7. Make sure to set the idol gear properly. ISX has floating gears as they are on a floating hub. a. The gears float because of the backlash. b. There must be backlash on the gears. c. There also must be torque between all of the gears. d. The timing must be set properly between the gears. e. In a running engine the gears must be unloaded. Only the Detroit 60 Series has similar floating gears.

8. Pay special attention to the dual overhead cams: one for the valves and injectors and the other for the Jake Brakes.

9. Overall, strictly follow the service manual. Stick to OEM specifications and tolerances as this engine is a very precise piece of equipment and has little room for error. From the staff at Blake’s Remanufacturing Services, LLC, Denver, CO
