The Research of Over-Piston Clearances of the Automotive Diesel Engines
The results of the researches of over-piston clearances in modern automotive engines are presented. It is established that the over-piston clearance in diesel engines is 0.9...1.35 mm. It is provided by a division of sleeves and pistons into groups, the use of steel gas-tight joint gasket different in width, the installation of different-walled connecting rod bush of the engines. The optimum clearance ensures the fuel, economic and environmental performance of the vehicle in in use guaranteed by the manufacturer.
