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[edit]

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[edit]

Gasoline versions[edit]

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.

The specificity of K4J and K4M engines is that they have a 16-valve cylinder head, similar to the F4P and F4R versions of F-Type engine, over the K4J and K4M engines share the same distribution kit and even water pump that the F-Type engine 16 valves (F4P and F4R).

Diesel versions[edit]

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[edit]

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). The Delphi injection systems have been replaced with Bosch ones in the Euro 5 versions.[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] Torque outputs range from 160 to 260 Nm at 1,750 rpm.

The engine has been in production since 2001, with over 9 million units sold as of 2012. Improvements over this period have included coating the tappets to reduce friction by 40%; redesigning the injector spray angle, resulting in a 15% reduction of NOx during combustion and a small improvement in torque; and fitting new piston rings, reducing the tension on the belt-driving engine accessories and optimizing the dimensions of the base engine. The injection pattern has been altered to have two pilot injections over a wide operating range, reducing combustion noise by up to 3 decibels. Still newer technology also includes using a variable-pressure oil pump, and adding stop/start battery technology and low-pressure exhaust-gas recirculation. The K9K engine is produced in Bursa, Turkey; Chennai, India; and Valladolid, Spain. Emissions-wise, it emits as little 90 g/km of carbon dioxide.[11]
