Cummins isx15

Cummins ISX is an inline 6-cylinder turbocharged diesel engine with about horsepower and pounds-feet of torque.

It goes without saying that the Cummins ISX is one of the most popular and well loved diesel engines on the road today. And the only engine offered by every major Class 8 truck manufacturer. Notoriously, every model and rendition of the ISX has had issues with the camshaft. This is largely because of an issue with the rocker arms. An issue in production with the rocker arms starved the components of proper oil from which makes them stick and hit the camshaft. This will eventually cause the lobes to become flat. The ISX is a mid stock steel cylinder liner equipped engine.

The Cummins X-series engine is an Inline Straight -6 diesel engine produced by Cummins for heavy duty trucks and motorcoaches , replacing the N14 in when emissions regulations passed by the EPA made the engine obsolete. Originally called the "Signature" series engine, the ISX uses the "Intellect System" hence the "IS" which is the moniker for the full authority, on highway fuel system Cummins pioneered to further improve the engine. This engine is widely used in on highway and vocational trucks and is available in power ranging from hp all the way to hp lb-ft. Cummins also produced a hp and lb-ft version for the RV market. Until this engine was a dual overhead cam design with one cam actuating the injectors and the other the valve train. This injection system is known as HPI high pressure injection where the injectors are cam-actuated to create injection pressure. The fuel system uses an Integrated Fuel System Module IFSM with a lift pump, gear pump, pressure regulators, shutoff valve, metering and timing actuators to deliver fuel to the injectors. It has a one piece valve cover that is either plastic or on older models a chrome plated steel cover otherwise known as the Signature or ISX CM In , the ISX CM brought cooled exhaust gas recirculation EGR which takes exhaust gas and recirculates it back into the intake of the engine lowering the combustion chamber temperatures limiting the formation of NOx. In motorhomes this was available as a or HP version. SCR consists of a diesel exhaust fluid DEF - composed of urea and water injection system: holding tank, pump, controller, and injector and an SCR catalyst brick. DEF is heated, pumped and injected into a decomposition tube which then reacts with the exhaust reducing NOX.

Today, cummins isx15, we'll look at the cummins isx15 most common problems with the Cummins ISX engine and why drivers prefer this engine. Starting in the Cummins Signature was released to the Australian market to replace the out going N

Ever-advancing technology and emissions regulations are the two biggest drivers of engine development in the world. When the ISX15 Cummins began to phase out the legendary N14 back in the late s, it had some very big shoes to fill. Now, 23 years later, many would say the ISX15 more than lived up to the hype. So if the ISX15 later became the X15, how similar are these two power plants? If only it were that simple…. Given the fact that it was being produced during the emissions crunch, several different versions of the ISX15 exist. Foundationally, the ISX15 Cummins is sound, with a robust cast-iron block and head design, as well as mid-stop cylinder liners.

When the coveted and rock-solid reliable N14 Cummins neared the end of its production run, the global, Columbus, Indiana-based engine manufacturer launched its replacement: the ISX Over the course of its year production run, exhaust gas recirculation EGR , a diesel particulate filter DPF , and selective catalytic reduction SCR were all added to the ISX15, yet the engine retained its reputation for durability and even the promise of going 1 million miles before requiring an overhaul. The other part of the story is that the ISX15 built a reputation for being one of the most fuel-efficient engines in its class, and many would argue it is one of the most fuel-efficient over-the-road diesels ever produced. The inline-six ISX15 displaces ci thanks to its 5. The block of our Cummins ISX is cast from gray iron and accommodates mid-stop, wet cylinder liners, and the cylinder head is cast iron as well. The second camshaft actuated the valvetrain and engine brake. Another notable way the ISX15 separated itself from the N14 it replaced was due to the fact that it featured fully electronic systems the N14 did not. When Cummins revamped the ISX15 around the use of high-pressure common-rail injection, the cam lobe problems that were inherent with cam-driven unit injection systems all but ceased and the engine took a technological leap forward. The high-pressure fuel system produced injection pressures as high as 35, psi and utilized solenoid-actuated injectors capable of pulling off five events per combustion cycle. The ISX15 was forced to change with the times.

In ECM , the ISX15 also went common-rail, a high-pressure up to 35, psi injection system that no longer relied on a camshaft to fire the injectors—and it featured solenoid-style injectors capable of pulling off five injection events per combustion cycle. Turbo lag problems are generally known to result in engine damage, meaning the earlier you diagnose the issue, the better.
