Cummins C Series engine
Encyclopedia : C : CU : CUM : Cummins C Series engine
The Cummins ISC is a straight-6 diesel engine, design by a Cummins production line, which is 8.3 liters in displacement. This went into production in 1997 by Cummins. The engine was built off its predecessor, the Cummins C 8.3-liter engine.
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 performance on this engine.
The Cummins ISC also has a sister engine which is designed off the existing ISC 8.3 liter block which runs on compressed natural gas. Cummins reintroduced this engine as the C PLUS engine which has a maximum power rating of 280 hp (209 kW). A few thousand units of this engine engines are now roaming in the world operating on a variety of applications.
In 2004 this engine did not pass the emissions requirements set for on-highway diesels for the urban bus industries. Due to this the engine went out of production in the urban-bus market.
