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.
