BorgWarner Chain Drive Systems Arrive on Cummins ® 5.0-liter V8 Diesel Engine

BorgWarner, a leading American automotive components and parts supplier, is further expanding its engine timing systems and drive chains into the North American light-duty diesel market with the Cummins® 5.0-liter turbodiesel V8 engine family. Enhanced particularly for Cummins V8 engines, the company’s engine timing system includes arms, bushing timing chains, tensioners, sprockets, and guides. Additionally, BorgWarner supplies chains for the fuel injection pump drive and oil pump drive, both designed for low noise and wear resistance.

Joe Fadool, President and General Manager, BorgWarner Morse Systems, said that BorgWarner’s bushing chains are ideal for diesel engines. He noted that offering a durable, compact package at a lower cost than gear systems enables engine manufacturers like Cummins to deliver high performance with enhanced fuel economy. “We are proud to work with Cummins to offer drivers exciting new options in the North American light-duty diesel market.”

The tough environment in diesel engines can cause engine timing chains to elongate, resulting in inefficient cam timing. In order to boost durability, BorgWarner’s bushing chains utilize specially shaped profiles and oriented bushings. Guides and arms are engineered for small package size and low mass to reduce emissions and enhance fuel economy. Chain tensioners are mechanically and hydraulically tuned to meet the exclusive demands of the Cummins engine. Sprockets come with modified tooth profiles which are designed to offset noise and vibration. As an integrated system, each component of the engine timing system is enhanced to resist wear, reduce friction and decrease vibration for accurate timing, low noise, long service life and enhanced fuel economy.
