Renault announces 1.6-litre twin turbo diesel engine
Renault has joined the long list of manufacturers who are downsizing their engine capacities. We have already seen Renault come out with turbo petrols and now the French manufacturer has announced a new engine called Energy dCi 160 Twin Turbo. This is a 1.6 litre twin-turbo charged diesel unit which makes 162PS of maximum power and 380Nm of torque. Renault claims that this new engine gives the power of a 2.0-litre unit and at the same time reduces fuel consumption and CO2 emissions by 25 per cent.
Renault's twin turbo diesel engine
This engine has many advanced technologies working in tandem to give it better performance, fuel consumption and emission figures compared to a conventional 2.0l motor. 'Twin-Turbo' technology has been used to ensure better driveability with good low-end torque and optimum top end. The first turbo charger out of the two is a low inertia turbo which gives good pickup lower down in the rev range mainly due to accessibility of 90 per cent torque right from 1500rpm. The second turbo takes control at higher rpm range and ensures linear, smooth acceleration all the way up to maximum revs. Other attributes derived from Renault's F1 expertise are transverse water flow system, diamond like carbon finish of cam followers and U-Flex piston rings. Together these reduce friction, enable better engine cooling and hence deliver better performance.
This engine will not be coming to India in the near future but when it does come expect it to power Renault's top-end cars.
