Chronology
Predecessor Renault Energy engine

The K-Type is a family of inline-4 automobile engines developed and produced by Renault since 1995. 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 driven by a toothed timing belt and an aluminium cylinder head. This engine is available in petrol and diesel versions, with 8 or 16 valves.

History

The K-Type engine is an evolution of the Energy engine, itself derived from the Cléon-Fonte engine in which a hemispherical head incorporating a 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 the use of non-removable cylinder liners. The first K-Type appeared on the Mégane with a capacity of 1.6 L (1,598 cc). [1]

Evolution

Gasoline versions

In 1998, a 16-valve derivative of the K7M engine appeared in the Renault Laguna Phase 2, named the K4M. This new engine replaced the 1.8 litre F-Type engine fitted to the Laguna 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

The K9K engine - diesel version with 1.5 L (1,461 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 1.4 L (1,390 cc). It is an evolution from Renault Energy ExJ.

Predecessor Renault F-Type engine
Successor Renault R-Type engine

The K9K is an automobile engine family – a group of straight-4 8-valve turbocharged Diesel engines co-developed by Nissan and/or Renault, and also Daimler AG (where it is called OM607). The turbochargers used with this engine are provided by Garrett and BorgWarner. [10] It has a displacement of 1461 cc and is called 1.5 dCi (direct Common-rail injection). Fuel injection systems were supplied by Delphi on the lower power level versions (up to 66 kW (90 PS; 89 hp) and by Continental (ex Siemens) on the higher power level versions (70 kW (95 PS; 94 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. [11] 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); 100 PS (74 kW).

In Euro 4 standards, their power levels are 70 PS (51 kW); 85 PS (63 kW); 106 PS (78 kW).

In Euro 5 standards, their power levels are 75 PS (55 kW); 90 PS (66 kW); 110 PS (81 kW). [11] Torque outputs range from 160 to 260 N⋅m (118 to 192 lb⋅ft) at 1,750 rpm.

The engine has been in production since 2001, with over 10 million units sold as of April 2013. 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 (3.2 oz)/km of carbon dioxide. [12]
