Renault R-Type engine

The R-Type is a family of straight-4 turbocharged diesel engines developed by Nissan and/or Renault, and also Daimler in the case of the R9M/OM626. Released in 2011, it replaced the 1.9 dCi engine in Renault's range and the 2.0 dCi in the Nissan Qashqai, and in 2015, it also replaced the 2.0 dCi in the Renault Mégane as well. When launched, the engine produced 130 PS (96 kW; 128 hp). Renault later introduced a higher-powered twin-turbocharged variant producing 160 PS (118 kW; 158 hp).

R9M 130PSEdit

R9M 130PS was introduced in 2011.

Developed within the framework of the Alliance, the newcomer's performance credentials were made similar to those of its predecessor, the 1.9 dCi 130 engine. This 1.6-litre power plant delivered peak power of 130 PS (96 kW; 128 hp) and torque of 320 N⋅m (236 lb⋅ft) available across a broad rev-band.

This new block came with a change in Renault's engine downsizing policy. More downsizing was to be obtained, thanks to the shortening of the stroke of the pistons and a redesign of the reciprocating parts. The cylinder's swept volume was reduced and thereby diminished the amount of fuel being burned during each cycle. Performance levels were maintained, however, by improving turbocharging efficiency.

R9M 160PSEdit

R9M 160PS was launched in February 2011.[4] It is twin-turbocharged, derived from the new Energy dCi 130. It produces 160 PS (118 kW; 158 hp) from a capacity of 1.6 L (1,598 cc) – that’s a specific power output of 100.1 PS (73.6 kW; 98.7 hp) per litre. Peak torque 380 N⋅m (280 lb⋅ft) is available from 1,750 rpm. Paired with a dual clutch EDC gearbox, this driveline outputs CO2 emissions of 99 g (3.5 oz) per kilometre.

Applications:

R9N 120PSEdit

R9N 120PS was launched in 2018

Developed within the framework of the Alliance, the newcomer's performance credentials are similar to those of its predecessor, the 1.9 dCi 130 engine. This 1.7-litre powerplant delivers peak power of 120 PS (88 kW; 118 hp) and torque of 300 N⋅m (221 lb⋅ft) available across a broad rev-band.

Applications:

R9N 150PSEdit

R9N 150PS was launched in 2019

This 1.7-litre power plant delivers peak power of 150 PS (110 kW; 148 hp) and torque of 340 N⋅m (251 lb⋅ft) available across a broad rev-band.
