Passenger Car Diesel Engine with Steel Piston English Free Members only

Increasing pressure on CO2 reduction and actual consumption for customers led to find technological solutions within the frame of forthcoming emission regulation. The steel piston has been applied for a long time on truck Diesel engines. After deep investigations on combustion, friction and reliability, Renault has decided to introduce this technology on a mass production engine. This development was completed in close cooperation with a major automotive supplier and the steel piston will be introduced on a 1.5L Diesel engine for Passenger Cars.
The aim of this paper is to explain design, combustion and friction impacts resulting in better efficiency and CO2 emission reduction.
