METHOD TO IMPROVE EFFICIENCY OF DIESEL ENGINE Russian patent published in 2001 - IPC

FIELD: mechanical engineering; maintenance and repair of diesel engines. SUBSTANCE: proposed method comes to the following: with engine operating at rated crankshaft speed compression in cylinders determining wear of cylinder-piston group is found and, depending on obtained results, nozzle needle lift commencement pressure is set to provide minimum smoking of exhaust gases and maximum effective horsepower of engine at such wear of cylinder-piston group. Invention is aimed at increasing power output and fuel economy, reducing contamination of ambient atmosphere with incompletely combusted products owing to provision of complete combustion of fuel in diesel engine cylinders. EFFECT: reduced fuel consumption and pollution of atmosphere. 3 cl, 14 dwg
