Cummins M11
The Cummins M11 is a six cylinder, 10.6 litre diesel engine introduced in 1994. It was built off of the previous L10 engine (same 4.921" cylinder bore, but a longer 5.787" piston stroke compared to the L10's 5.354" stroke).
In 1996, Cummins made changes to the engine and added their CELECT Plus electronic control system to improve fuel efficiency, performance, and reliability. This was called the M11 Plus or M11E. The M11 Plus meets the 1998 CARB and EPA emissions standard of 4.0 g/bhp-hr of nitrogen oxides (NOx) and 0.05 g/bhp-hr of particulates by using a catalyst.
The M11 Plus was succeeded in 1999 by the Cummins ISM, which itself was succeeded by the ISX11.9, released on July 20, 2010.
