TheRenault-Nissan MR engine family consists ofstraight-four16-valve all-aluminium andwater cooledautomobile engines withvariable valve timing co-developed byRenault andNissan. Renault calls it theM engine. Other noteworthy features of this engine family include acoustically equal runner lengths and a tumble control valve for theintake manifold, a "silent" timing chain, mirror finishedcrankshaft and camshaft journals, andoffset 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.
Third generation E-power hybrid 3 cylinder 1.5L engine.[citation needed]
Applications:
TheMR16DDT is a 1.6 L (1618 cc) DIG-T (Direct Injection Gasoline-Turbocharged)inline-four16-valve engine, with abore xstroke of 79.7 mm × 81.1 mm (3.14 in × 3.19 in).

TheM9R andM9T are a family ofstraight-four16-valveturbochargeddiesel engines co-developed byNissan andRenault, and alsoMercedes-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.[5] 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. TheM9T is directed to heavier vehicles like the Nissan Navara or the Renault Master. It features a bore and stroke of 85 mm × 101.3 mm (3.35 in × 3.99 in) for a total displacement of 2,299 cc (2.3 L), balancer shafts,[6] typical speeds are 3500 rpm for maximum power and 1250 rpm for maximum torque.
Low output versions of theM9R for the Renault Trafic II at 66 and 85 kW (90 and 116 PS; 89 and 114 hp) had been replaced by the Renault R engine with the introduction of the Trafic III, while versions starting from 96 kW (131 PS; 129 hp) include VNT chargers. The top version of the Navara utilizes theM9T withtwin-turbochargers and 190 PS (140 kW; 187 hp). During production period engines had been updated up toEuro 6 (in early 2017).

TheM9R is a 2.0 L (1995 cc)16-valveturbochargeddiesel engine developed by theRenault–Nissan Alliance, and first installed in theRenault Laguna in 2006. It is available in the 150 PS (110 kW; 148 hp) tune inNissan Qashqai,Nissan X-Trail,Renault Mégane,Renault Koleos andRenault Laguna models. In this trim the engine achieves maximum power at 4000 rpm and maximum torque of 340 N⋅m (251 lb⋅ft) at 2000 rpm. A 175 PS (129 kW; 173 hp) form with particulate filter is available inRenault Laguna andNissan X-Trail models. A 180 PS (132 kW; 178 hp) 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 theEuro 4 and 5 standards for exhaust emissions. The 150 PS (110 kW; 148 hp) New Mégane and New Laguna respectively emitted 144 g (5.1 oz)/km and 154 g (5.4 oz)/km ofCO2 and the 129 kW (175 PS; 173 hp) version of New Laguna 2.0 dCi emits 159 g (5.6 oz)/km of CO2; they all comply with theEuro 5 standards for exhaust emissions.
In 2011 the 96 and 110 kW (131 and 150 PS; 129 and 148 hp) M9R engines has been updated with an optional package to lower exhaust emissions (Euro5) andfuel 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:
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 84 mm × 90 mm (3.31 in × 3.54 in) to 85 mm × 88 mm (3.35 in × 3.46 in) - 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, 160 and 200 PS (118 and 147 kW; 158 and 197 hp), 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:

TheM9T is a version specifically designed forlight commercial vehicles that is manufactured by Renault inCléon. It was introduced on theRenault Master and itsbadge engineered derivatives, initially with power ranging from 75 kW (101 hp) to 110 kW (150 hp), and torque ratings starting at 185 N⋅m (136 lbf⋅ft) up to 350 N⋅m (260 lbf⋅ft).[7][8] Later, it was also introduced to theNissan Navara and theMercedes-Benz X-Class.[9][10] Nissan calls it theYS23 while in Mercedes-Benz vehicles, it is named theOM699. The engines with lower power ratings feature a single fixed geometry turbocharger,[11] while the more powerful versions have avariable-geometry turbocharger ortwin-turbochargers.[12] The engines are compliant with theEuro 6emission regulations.[13]
