Predecessor | Renault Energy engine Renault F-Type engine |
The K-Type is a family of inline-4 automobile engines developed and produced by Renault since the mid-1990s. This is an internal combustion engine, four-stroke, with 4 cylinders in line bored directly into the iron block, water cooled, with tree (s) driven overhead camshafts (s) by a toothed timing belt, with an aluminum cylinder head and valve head. This engine is available in petrol and diesel versions, with 8 or 16 valves.

History
The K-Type engine is an evolution of "Energy engine", it is intended to replace. The "Energy engine" was already an evolution of "Cléon-Fonte engine" in which a hemispherical head incorporating head camshaft driven by a toothed timing belt was fitted. The K-Type engine is the ultimate evolution of the "Cléon-Fonte engine". The main modification of the K-Type engine is operated at machining cylinder, since this engine has removable liners. The 8-valve cylinder versions species is taken from Energy engine. The first engine K appears on the Megane 1 with a capacity of 1598 cm3, with a yoke 8 valves, K7M.[citation needed]
Evolution
Gasoline versions
In 1998, the K7M engine is topped by a 16-valve cylinder head under the hood of the Laguna 1 Phase 2 - the K4M. This new engine replaces the 1.8 "F-Type engine" of Laguna 1 Phase 1.
Diesel versions
The K9K engine - diesel version with 1461 cc - appeared on the Clio 2 Phase 2, to replace the 1.9 D ("F-Type engine" ). This engine is equipped with high-pressure direct injection common-rail.
KxJ petrol engine
The KxJ displaces 1390 cc or 1.4 L. It is an evolution from Renault Energy ExJ.

The K9K is a family of straight-4 turbocharged diesel engines co-developed by Nissan and Renault. The turbocharger is provided by Borg-Warner.[9] It has a displacement of 1461 cc and is called 1.5 dCi (diesel Common-rail injection). Fuel injection systems were supplied by Delphi on the lower power level versions (up to 66 kW/90 hp) and by Continental (ex Siemens) on the higher power level versions (70 kW/95 hp and higher). Delphi systems were changed with Bosch ones in Euro 5 version.[citation needed]
There are three versions of this engine: a low power version, a high power version and a high power version with variable geometry turbocharger.[10] Their maximum power output varies depending on the emission standards they meet. In Euro 3 standards, their power levels are 65 PS (48 kW), 80 PS (59 kW) and 100 PS (74 kW). In Euro 4 standards, their power levels are 70 PS (51 kW), 85 PS (63 kW) and 105 PS (77 kW). In Euro 5 standards, their power levels are 75 PS (55 kW), 90 PS (66 kW) and 110 PS (81 kW).[10]
