Renault R9M engine

The R9M Renault engine is a 1.6L automotive internal combustion Turbo diesel four-stroke, with 4 cylinders in line bored directly in the block, water-cooled, with a 5-step crankshaft, 2 camshafts head driven by a chain distribution, with a cylinder head in aluminium, valve head, manufactured by Renault, making its appearance on the Scenic III.

History

These 4 cylinders is completely new designed specifically for diesel applications. Renault started from a blank page to design this block. Engineer Philippe Coblence is head of the R engine design office, which looked after F1 engines at the start of the 2000s. Three meeting points between F1 technology and this new R engine: square engine, circulation transverse water, reduction of internal friction.

Appeared in 2011 on the Scénic III, this first 1.6 dCi version of the R9M type is equipped with technologies usually reserved for more high-end engines, it is intended to replace the “F engine” which appeared in the early 1980s on the Renault 9 and Renault 11, therefore the 1.6 dCi type R9M replaces the 1.9 dCi type F9Q of equal power, with increased torque or 130 and reduced consumption and emissions along with a more powerful 160 twin-turbocharged version.

With a smaller displacement, this engine consumes less than the one it is intended to replace, while maintaining performance thanks to improved supercharging. This block and its mobile coupling have been designed to withstand the strong constraints inherent in diesel engines.

The pistons in this engine feature U-shaped segments, a technology inspired by F1. It is equipped with a variable-flow oil pump which therefore uses less energy because the pumped oil is entirely used to lubricate the engine and not delivered. Its cooling circuit is in 2 parts, when cold the water does not circulate around the cylinders in order to accelerate the warm-up of the engine.
