The K-Type series comprises inline-4 engines engineered and manufactured by Renault starting in 1995. These engines incorporate a cast iron cylinder block combined with an aluminium cylinder head, utilize water cooling, and employ overhead camshafts driven via a toothed timing belt. Both petrol and diesel variants are offered, featuring either 8 or 16 valves.
History
The K-Type engine traces its lineage back to the Renault Energy engine, which itself originated from the Renault Cléon-Fonte engine. A significant innovation introduced with the K-Type is the integration of fixed cylinder liners. The inaugural K-Type unit was unveiled in the first generation Mégane, boasting a displacement of .
Petrol variants
In 1998, the 16-valve K4M engine was launched with the Renault Laguna Phase 2, succeeding the earlier 1.8-litre Renault F-Type engine that powered Laguna Phase 1 models. The K4J and K4M petrol engines share a common 16-valve cylinder head design and distribution components, including the water pump, which are also found in the F-Type's F4P and F4R versions.
Diesel variants
The K9K diesel engine, displacing , debuted on the Clio 2 Phase 2 as a replacement for the previous 1.9 D Renault F-Type engine. This engine incorporates advanced high-pressure common-rail direct fuel injection technology.

K9K dCi
The K9K series comprises inline-four, 8-valve turbocharged diesel engines jointly developed by Nissan, Renault, and formerly Mercedes-Benz Group (where it was designated OM607/OM608). This engine family has a displacement of 1461 cc and is marketed under the 1.5 dCi name, reflecting its direct common-rail injection technology. Turbochargers are sourced from Garrett and BorgWarner. Depending on the power variant, fuel injection systems differ: lower output models utilize Delphi units, while higher output versions employ Continental (previously Siemens) systems; Bosch replaced Delphi in Euro 5 compliant engines.
There are three primary variants: low power, high power, and high power equipped with a variable-geometry turbocharger. Output levels correspond to European emission categories as follows:
- Euro 3: 65 PS, 80 PS, 100 PS
- Euro 4: 70 PS, 85 PS, 106 PS
- Euro 5: 75 PS, 90 PS, 110 PS
Torque figures range between 160 and 260 Nm at 1,750 rpm.
Since its introduction in 2001, the K9K engine has surpassed 10 million units sold worldwide. Continuous refinements have been implemented including tappet coatings that reduce friction by 40%, injector spray angle modifications that decrease NOx emissions by 15%, optimized piston ring designs that lessen accessory belt tension, and enhanced injection timing featuring two pilot injections which cut combustion noise by up to 3 decibels. Recent updates incorporate variable-pressure oil pumps, stop/start battery technology, and low-pressure exhaust gas recirculation systems. Manufacturing plants are located in Bursa (Turkey), Chennai (India), and Valladolid (Spain). The engine's CO2 emissions average around 90 g/km.
