Cummins C Series engine
Encyclopedia
The Cummins ISC is a straight-six diesel engine
, design by a Cummins
production line, which is 8.3 litres (506.1 cu in) in displacement
. This went into production in March 1998 by Cummins. The engine was built off its predecessor, the Cummins C 8.3 litre engine originally introduced in 1985 as the 6C8.3 (this was co-designed with the Case Corporation
, along with the smaller 6B5.9
). The first electronic version, known as the C8.3E and designed for the urban bus market exclusively, went into production in late 1996.
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 litre cylinder block
which runs on compressed natural gas
(CNG). Cummins reintroduced this engine as the C PLUS engine which has a maximum power rating of 280 hp. A few thousand units of this engine engines are now roaming in the world operating on a variety of applications.
