Renault has showcased a prototype version of a turbocharged and supercharged two-cylinder, two-stroke diesel engine at it’s Innovations@Renault event in Paris. This prototype two-stroke diesel engine is currently under study and will pass through additional stages of development before it goes into production.
Renault has not revealed any performance details of the engine but claims that the supercharged and turbocharged motor produces between 48bhp and 68bhp and up to 14.8kgm. This prototype version is an attempt by Renault to halve the amount of space needed in the engine bay without increasing engine noise.
The prototype two-stroke diesel engine is half the size of the brand’s four-stroke 1.5-litre dCi unit. Although the 730cc two-cylinder engine is based on the 1.5-litre dCi, but it weighs less than 100kg, that’s around 40kg lighter than the 1.5-litre dCi motor. According to Renault, the aim is to make the engine around 15 percent more efficient than the equivalent four-cylinder unit. Renault has said that the two-stroke engine is not fully ready yet.
