Abstract
An anti-backlash camshaft gear has been developed for the Cummins B Series 4-cylinder diesel engines. This gear reduces the gear train impact to result in lower engine noise levels and improved engine sound quality. The greatest benefit is at the low idle condition, where an engine noise reduction of about 2 dB(A) has been observed. Noise reductions throughout the engine speed and load range are also significant. The first application of this noise reduction gear is for a light duty pickup truck.
