Renault Is Working On A 2-Stroke 2-Cylinder Twin-Charged Diesel Engine
The new motor is also air-cooled, with only the PEC remaining connected to a radiator.

Two-stroke diesel engines are commonplace in large container ships. Their thermal efficiency is around 50 per cent while four-stroke diesels struggle to reach 35 per cent. The difficulty, until now, has been in adapting two-stroke technology for an engine small enough for automotive use, which Renault is aiming to solve with its 'POWERFUL' (POWERtrain for Future Light-duty vehicles) project.

The two-cylinder engine is only half the size of Renault's 1.5-litre dCi diesel, weighs 40 kg less, ideally suited for small vehicle platforms. This 730cc unit is both super-charged and turbo-charged and produces between 35kW and 50kW (48hp-68hp) with 112-145Nm of torque from 1,500rpm.

Initial tests are encouraging, although the performance needs to be improved before Renault could consider introducing it. The engine is being developed with 18 industrial, scientific and academic partners in France, Spain and the Czech Republic, with investment from the European Union.
