renault d4ft

The Renault DiET engine also known as "D engine" or "D-Type" is a straight-4 automobile petrol engine from Renault designed to replace the existing Cléon-Fonte engine in the Renault Twingo.
The D Engine was designed because the 1. 2-liter Energy Engine with its hemispherical cylinder head and exhaust up to the front of the head could not fit under the hood of the First generation Twingo.
In 1997, new European pollution regulations went into effect. Renault could have kept the Cléon-Fonte 1. 2 on the Twingo and its Energy engine 1. 2 on the Clio, by equipping them with multipoint injection and other technological improvement, but rather than investing in updating two different engines and because of the unexpected success of Twingo, they decided to opt for a new engine that could be mounted in the Twingo as well as the Clio – hence the creation of the D-Type Engine....
