The Renault-Nissan MR engine family consists of three and four-cylinder, all-aluminium and water cooled automobile engines with variable valve timing, initially developed by Renault and Nissan, and also Mercedes-Benz since 2010 in the case of the M9T/OM699. They all have four valves per cylinder. Renault calls this engine family the M engine. Other noteworthy features of this engine family include acoustically equal runner lengths and a tumble control valve for the intake manifold, a "silent" timing chain, mirror finished crankshaft and camshaft journals, and offset cylinder placement in an attempt for increased efficiency.
The MR engine family features 'under stress' manufacture, meaning while the block is being bored, a torque plate puts the block under stress. The block becomes temporarily distorted until the head is torqued onto it, at which point the block is pulled into the correct shape.

M9 diesel The M9R and M9T are a family of straight-four 16-valve turbocharged diesel engines co-developed by Nissan and Renault, and also Mercedes-Benz Group in the case of the M9T/OM699. Following Renault's designation plan, the last letter (M9R resp. M9T) is to indicate the swept volume of 2.0 L resp. 2.3 litres. Despite the similar names, the diesel engines are only loosely related to the MR gasoline engines. M9R is built at Renault's Cleon factory in Normandy. As of late 2018, a new version of the M9R using adBlue and with slightly different internal dimensions replaced the original M9R.
Features of the diesel engines include a cast-iron block, aluminium alloy cylinder head with double overhead camshafts, 16-valve layout and a bushes timing chain. The M9T is directed to heavier vehicles like the Nissan Navara or the Renault Master. It features a bore and stroke of for a total displacement of , balancer shafts,Brochure renault.com typical speeds are 3500 rpm for maximum power and 1250 rpm for maximum torque.
Low output versions of the M9R for the Renault Trafic II at had been replaced by the Renault R engine with the introduction of the Trafic III, while versions starting from include VNT chargers. The top version of the Navara utilizes the M9T with twin-turbochargers and . During production period engines had been updated up to Euro 6 (in early 2017).
M9R
The M9R is a 16-valve turbocharged diesel engine developed by the Renault–Nissan Alliance, and first installed in the Renault Laguna in 2006. It is available in the tune in Nissan Qashqai, Nissan X-Trail, Renault Mégane, Renault Koleos and Renault Laguna models. In this trim the engine achieves maximum power at 4000 rpm and maximum torque of at 2000 rpm. A form with particulate filter is available in Renault Laguna and Nissan X-Trail models. A variant is also available on the Laguna GT. In both engines maximum power is achieved at 3750 rpm and maximum torque is available from 1750 rpm.
In order to reduce vibrations, balance shafts are included in some versions of the engine. The 2.0 dCi engine in all its versions complies with the Euro 4 and 5 standards for exhaust emissions. The New Mégane and New Laguna respectively emitted /km and /km of CO2 and the version of New Laguna 2.0 dCi emits /km of CO2; they all comply with the Euro 5 standards for exhaust emissions.
In 2011 the M9R engines has been updated with an optional package to lower exhaust emissions (Euro5) and fuel consumption. These engines are tagged "2.0 Energy dCi 130" resp. "2.0 Energy dCi 150", typically maximum power is available at 3750 rpm and maximum torque at a minimum of 1750 rpm. The package comprises: Stop & Start Active thermal management Smart electrical management Variable capacity oil pump The CO2 values were thus reduced to 118 g/km for the Laguna both the 2.0 Energy dCi 130 and 2.0 Energy dCi 150.
Towards the end of 2018, the 2-liter M9R engine became the "M9R Gen 5" when it received a thorough redesign to comply with the increasingly stringent anti-pollution regulations: first of all the engine dimensions were changed, from to - using the same bore as the larger M9T but with nearly no change in displacement, which increases by 2 cc to 1997 cc. Another important innovation introduced with this update was the BluedCi technology, which involves the installation of a small tank of adBlue, a chemical additive that is injected upstream of the catalyst and which, when combined with the exhaust gas, causes a reaction chemistry within the catalyst itself. This reaction transforms most of the nitrogen oxides into harmless nitrogen and water vapor. This engine debuted in two power levels, , in the Renault Talisman II 2.0 Blue dCi which was produced from December 2018. In December 2020 a single 190 PS version replaced both of the earlier versions.
The engine is fitted to the following vehicles: 2007–2011 Nissan Qashqai 2007–2012 Nissan X-Trail 2005–2015 Renault Laguna 2006–2015 Renault Mégane 2007–2016 Renault Koleos 2006–2014 Renault Espace 2007–2010 Renault Vel Satis
