The ISX15 CM2250 and CM2350 has eliminated the injector camshaft due to the advent of the common rail fuel system in which the fuel is pressurized from a high pressure, multiple piston pump, transferred through tubing to a rail where fuel is stored under extremely high pressures up to 35,000 psi. In 2023, Cummins unveiled the X10 and X15N engines.
Injection pump for a 12-cylinder diesel engine An injection pump is the device that pumps fuel into the cylinders of a diesel engine . Traditionally, the injection pump was driven indirectly from the crankshaft by gears, chains or a toothed belt (often the timing belt ) that also drives the camshaft .
The 5.9 L Cummins, also known as the "12-Valve" Cummins was the first member of the Cummins B-Series to be used in a light truck vehicle. The 6BT used Bosch fuel systems, injector, and VE rotary pump and P7100 inline injection pumps. Some early 6BTs were supplied with CAV rotary pumps instead, before the Bosch system became the sole standard.
Early Lucas electronic diesel unit injector. A unit injector (UI) is a high-pressure integrated direct fuel injection system for diesel engines, combining the injector nozzle and the injection pump in a single component. The plunger pump used is usually driven by a shared camshaft. In a unit injector, the device is typically lubricated and ...
The Cummins M-series engine is a straight-six diesel engine designed and produced by Cummins.It displaces 10.8 litres (659.1 cu in).Introduced as the M11 in 1994, it was built on the previous L10 engine (same 4.921 inches (125.0 mm) cylinder bore, but a longer 5.787 inches (147.0 mm) piston stroke compared to the L10's 5.354 inches (136.0 mm) stroke).

The ISC was introduced in 1998 and used a CAPS electronically controlled injection system along with a 24 valve head, vs 12 valves on the 6C8.3. By late 2003, Cummins announced that they will revise the engine to sport a High-Pressure Common-Rail (HPCR) system to help with emissions and also a variable geometry turbocharger system to help with ...
The Unit Pump system [1] is a modular high-pressure diesel injection system, which is closely related to the unit Injector system, and is designed for use in commercial vehicle diesel engines. [ 2 ] The systems use an individual injection pump mounted on the engine block for each cylinder so it is primarily designed for OHV or "cam in the block ...
