Cummins ISX Series Information:

The Cummins ISX Series Engine is one of the most popular diesel engines in circulation today. The Cummins ISX is an Inline (Straight)-6 diesel engine produced by Cummins for heavy duty trucks and motorcoaches, replacing the N14 in 2001 when emissions regulations passed by the EPA made the engine obsolete. Originally called the “Signature” series engine, the ISX uses the “Interact System” (hence the “IS” which is the moniker for the full authority, on highway fuel system Cummins pioneered) to further improve the engine. The Cummins ISX series is widely used in on highway and vocational trucks and is available in power ranging from 430 hp all the way to 620 hp 2050 lb-ft. The QSX is the off-highway version of the ISX with the Q standing for Quantum. The QSX is used for industrial, marine, oil & gas and other off-highway applications. Cummins also produced a 650 hp and 1950 lb-ft version for the RV market.
