Cummins introduces four-cylinder ISB
COLUMBUS, Ind. (Nov. 6, 2000) — Cummins Inc. introduced an electronically controlled four-cylinder engine for the light- and medium-duty truck market that is expected to comply with emissions regulations through 2008.
The 170-horsepower, 16-valve design is designed to use the technological advancements and performance from Cummins’s popular six-cylinder ISB engine and combine them with the reliability of its old B3.9 model.
The company said fleets that have switched from the B3.9 engine have seen a 20-30% increase in fuel efficiency.
The new engine has a High-Pressure Common Rail (HPCR) fuel system, vertically centred injection, and a rear-mounted gear housing, fuel pump, and accessory drive, designed to contribute to significantly reduced running noise.
It will initially be available for the walk-in van market.
