The Energy engine also known as "E engine" or "E-Type" is an automotive gasoline four-stroke internal combustion engine, 4 cylinders in line with a sleeved water cooled cast iron block, equipped with 5 crankshaft bearings, an overhead camshaft driven by a toothed timing belt and an aluminum cylinder head with 8 OHV. Developed and produced by Renault in the late '80s, making its appearance on the Renault 19.

History[edit]

In the late 80s, the Cleon-Fonte engine still fitted to the R4, Super 5, R9, R11, Express ... was getting old with its lateral camshaft design. Competing brands were mostly building modern engines with overhead camshafts. The Cleon-Fonte engine appeared in 1962 on the Renault 8 and Renault Floride . To launch the successor of the R9 and R11, the R19, Renault would develop a more modern engine . Renault modernized its old Cleon-Fonte motor with a new hemispheric cylinder head and an overhead camshaft, driven by a toothed timing belt, which give rise to the motor Energy in 1988. This new engine will also equip the Clio 1, Mégane 1 and even Express. But in 1993, launching the Renault Twingo, Renault will have to re-use the Cleon-Fonte engine because the "E engine", by its size with its hemispherical cylinder head and front exhaust, could not go under the hood of the little Twingo. The Energy ( E7F ) will gradually replaced the current engine D7F in 1996 on the Clio, following new standards of pollution control and high fuel consumption compared to other modern engines. The D7F engine will simultaneously replace the engines of Clio 1.2 Energy and the Twingo 1.2 Cleon-Fonte. As for the 1.4 Energy ( E7J ) of the Megane 1, it will be replaced by the K7J engine.

Evolution Engine[edit]

The Energy engine evolve into the K engine that will appear on the Megane 1. The main modification of the engine is operated at K machining cylinder, since this engine has removable liners. The head of Energy engine is kept on versions 8 valves species. The K engine will also be developed in 16-valve versions and will also be available in diesel version (K9K - 1.5 dCi).

ExF[edit]
