The ventilated exhaust is then able to lower the combustion chamber temperature. It injects urea, an active element in diesel exhaust fluid DEF , into the exhaust. Ammonia in the urea then chemically reacts with the NOx particles and converts them into nitrogen and water inside the catalytic converter. DEF reaches high temperatures in the holding tank, then pumps into the injector and decomposition tube, causing it to react to the NOx in the exhaust.
New advancements in emissions technology emerged when Cummins introduced the diesel particulate filter DPF. This system captures the exhaust produced from the combustion chamber and neutralizes the soot through oxidation. At one point, the ISX15 had a dual overhead camshaft design. One cam would activate the injectors, and the second initiated the valve train.
This dual camshaft design was a complicated injection system that was cam actuated to form injection pressure and deliver fuel. They also innovated the common rail fuel system, which eradicated the need for an injector camshaft to generate pressurized fuel. In the common rail fuel system, diesel fuel becomes pressurized via multiple piston pumps.
Then, it can be distributed through the tubing to the rail system for storage under extreme pressures— about 35, PSI or higher. The ECM can activate each fuel injector up to five times per combustion cycle, while the single camshaft improvement creates a better fuel economy and reduces emissions to stay parallel with EPA standards. This change increased fuel efficiency compared to previous versions.
A Cummins ISX engine is an Inline-6 diesel with a duel-fuel configuration — meaning it can run on diesel or natural gas — although diesel is the most common.
Throughout each improved generation, the Cummins ISX15 engine now comes complete with several prominent features that make it one of the most sought-after solution fulfilling engines on the market.
Compared to the original N14 series from the late s, the ISX15 now delivers an exceptional line of components that have been engineered and upgraded each year, including:.
Recirculation within the engine lowers the combustion temperatures, which reduces optimized MPG and emissions. Dual overhead camshafts: As noted above, if your ISX15 was manufactured before , it has a dual camshaft system.
The first cam creates high-pressure fuel injection for clean power, while the second has a set of lobes to operate the integrated engine brake. The second set of camshafts also moves the intake and exhaust valves. With a high-pressure fuel injection system, a marine engine can produce complete combustion. High-pressure fuel injection system: The high-pressure Cummins ISX fuel pump system forms a clean and complete combustion phase.
Integrated electronic controls: Engines produced after rely on an ECM. It also synchronizes interactions between the ABS, transmission, engine brake, cooling fan and other components. Low maintenance: An ISX15 engine can run up to 15, miles between oil and filter changes. Mid-stop cylinder liners: Cylinder liners within the ISX15 have a strong design to allow for variations in coolant chemistry. Particulate filter: An ISX engine has a fully integrated particulate filter for uncompromised performance by reducing particulate matter.
Single overhead camshaft: Versions of the ISX engine made after have a single camshaft system with a common rail fuel operation that relies on piston pumps to inject diesel.
Variable geometry turbocharger: The turbocharger has a sliding nozzle to boost durability and reliability. Its electric actuation enhances its responses and control for adjustment. The component also delivers a definite increase at any RPM.
Cummins has mastered the engineering process by integrating each possible solution into one unit. Address any problems immediately to avoid more severe damage.
Here are some tips to keep in mind before making engine repairs to your ISX engine :. Do you have a single or dual cam ISX15? Does it have an EGR system? When it comes to common ISX engine issues, some problems may not affect your engine depending on the year it was made. Clogged inlets came about in when recirculation was occurring, also affecting HP.
The turbocharger is one of the most notorious ISX15 failures and can be expensive to fix. While they are ideal for direct throttle response, VGTs often experience a buildup of carbon, soot, rust and other contaminants. You may feel no response from the engine or an extreme retort at low RPMs. The best fix is to clean the exhaust side of the VGT, replace its parts or swap it for a fixed unit. Another sign is if you notice white residue from the burnt coolant.
The rocker arms within your ISX engine may be damaging the camshafts, which causes an improper amount of oil to pass. When the rockers hit the camshaft lobes, it flattens them.
This deprivation causes your marine or generator application to experience performance issues. You can replace both the camshaft and rockers to deter the problem. Swapping rocker arms for new ones is vital. Otherwise, they will flatten the new camshaft as well. Problems with a timing wedge often happen after you repair or overhaul the camshaft. Over time, a buildup of contamination can form in the oil filter, resulting in a drop in oil pressure.
Avoid the timing wedge issue easily by simply changing the oil filter. The burning of a natural gas alternative preserves diesel thermal efficiencies.
The more efficient engine can produce less emissions in turn. The ISX can achieve this by altering ignition delay and injection timing. By examining the start of combustion SOC , the engine's computer is able to employ a predictive ignition delay correlation.
The predictive characteristics of the engine maximize both efficiency and useful power for the given fuel source. Compensations are made for the natural gas so that the power band and operating range are still functional for customers, while reducing emissions. This makes the Cummins ISX that burns natural gas one of the cleanest running diesel engines in the world. The DPF filters out the solid particles in the engine's exhaust, reducing tailpipe emissions.
The DPF does have to be regularly maintained, however, because of its intricate design. The emissions control system will institute a filter regeneration which burns off the particulates.
Any non-combustible materials found in lubrication additives will remain in the DPF, which can cause problems with back pressure and efficiency. An ash-less oil could mean that cleaning would be unnecessary, but can inhibit lubrication properties.
A zero-phosphorus oil has been studied and found to be ideal for DPF systems and lubrication. The oil displays passing results for both piston deposits and oil consumption, which means the DPF system would be optimized with use of zero-phosphorus, ultra low sulfur oil. DEF is system of injected urea that reduces the emissions of a diesel engine. Power cuts and driver warnings are also used when the DEF system has been tampered with or is not functioning properly.
Cummins has corrected several malfunctions and conducted customer based research of several million miles of on road use of the Cummins ISX to make the DEF system as functional as possible. The system is also required to de-rate power given any problems in order to reduce emissions to an absolute minimum. In early ISX engines an anti backlash gear train is used. The anti backlash gears allow the engine to operate with minimal gear rattle.
Cummins uses a gear train in the front of the engine which is inherently noisy. The anti backlash gearing makes the engine less noisy due to the reduced rattle while in operation. The anti backlash gear train comes at a cost of efficiency. The Cummins ISX 15 model equipped with anti backlash gearing suffers a friction loss. The gears must overcome more friction throughout their moving range than a standard gear. A standard gear in a Cummins ISX 15 needs to overcome 0.

Instead, they went a step ahead, completely overhauling its chassis, and gave it new mechanicals to bring it into the modern era. They bought a Ram pickup, took its chassis out, chopped off its rear end, and bolted it onto the body of the Power Wagon.
So now this Dodge truck shares most of its mechanical bits with the Ram , such as its frame rails, front suspension, transmission, brakes, differentials, and a ton of other things. The team decided to cut the chassis before the rear tires because they didn't want to use the leaf springs out of the Ram pickup.
They'd have had no use in the Power Wagon as the customer does not plan to use it to carry or tow anything; it'll just be a weekend cruiser , ferrying his family and friends around.
Instead, they fabricated a custom rear end for this truck and gave it a triangulated four-link suspension setup focused more towards off-roading.
They also used ADS shocks to ensure the truck had a nice ride. Though it's meant for cruising, this Dodge Power Wagon is still quite capable, with up to 10 inches of suspension travel all around. It uses inch tires on all four corners wrapped around Black Rhino wheels with a Beadlock pattern. Frankie explains that the truck uses conventional wheels they bought off the shelf but took all the fake plastic Beadlock stuff out and custom fabricated the bolts onto the rim to make it look more authentic.
Credit where its due, the 37s, with the custom wheels, does look pretty slick on this Power Wagon. Though there isn't much of it, the interior of the Power Wagon remains completely stock. It still has its original steering wheel and uses actual gauges on its metal dashboard. However, the team at P2 Fabrication did do one major upgrade with this Power Wagon, and that's to extend its wheelbase by 16 inches. They had to push back the rear wheels to make more room in the second row, as getting in and out was difficult in the truck's stock configuration.
For this, the team had to cut and then re-fabricate the rear quarter panel of the Dodge. Extending the wheelbase made more space inside the second row and significantly reduced the rear overhang. That made this truck look more proportionate than before. However, with this Dodge being more than 80 years old, it still had a few wooden frame components that had to be replaced with pieces made from metal. In his short drive with Frankie in the Dodge Power Wagon, Davis mentions that it offers a pretty high seating position.
He was a little nervous getting into the truck that only had lap belts, probably because of his gruesome Mercury Comet crash. But he still went on for a ride as he trusted the workmanship of the folks at P2 Fabrications. As Davis points out, thanks to the truck's massive inch tires, and an amazing suspension setup, it practically glides over all the bumps and potholes on the road.
