The Renault-Nissan MR engine family consists of straight-four 16-valve all-aluminium and water cooled automobile engines with variable valve timing co-developed by Renault and Nissan. Renault calls it 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.
The MR16DDT is a 1.6 L (1618 cc) DIG-T (Direct Injection Gasoline-Turbocharged) inline-four 16-valve engine, with a bore x stroke of 79.7 mm × 81.1 mm (3.14 in × 3.19 in). It was first introduced in the Nissan Juke small SUV in the autumn of 2010. Output is 140 kW; 187 hp (190 PS) and 240 N⋅m (177 lb⋅ft) of torque. The 2014 Juke NISMO RS FWD produced 158 kW; 212 hp (215 PS) and 285 N⋅m (210 lb⋅ft). In 2015, the Nissan Teana received this 1.6 Turbo as a replacement for the earlier 2.0-liter naturally aspirated engine. In 2013, it entered Renault's lineup in the Sport Clio as the M5Mt, where it generates 147 kW; 197 hp (200 PS) and 240 N⋅m (177 lb⋅ft).
Some of the pertinent features of the MR16DDT are:

Applications:
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. [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. The M9T 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 the M9R 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 the M9T with twin-turbochargers and 190 PS (140 kW; 187 hp). During production period engines had been updated up to Euro 6 (in early 2017).

The M9R is a 2.0 L (1995 cc) 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 150 PS (110 kW; 148 hp) 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 340 N⋅m (251 lb⋅ft) at 2000 rpm. A 175 PS (129 kW; 173 hp) form with particulate filter is available in Renault Laguna and Nissan 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 the Euro 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 of CO2 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 the Euro 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) 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:
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:

The M9T is a version specifically designed for light commercial vehicles that is manufactured by Renault in Cléon. It was introduced on the Renault Master and its badge 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 the Nissan Navara and the Mercedes-Benz X-Class. [9] [10] Nissan calls it the YS23 while in Mercedes-Benz vehicles, it is named the OM699. The engines with lower power ratings feature a single fixed geometry turbocharger, [11] while the more powerful versions have a variable-geometry turbocharger or twin-turbochargers. [12] The engines are compliant with the Euro 6 emission regulations. [13]
Applications:
The VQ is a family of V6 automobile petrol engines developed by Nissan and produced in displacements varying from 2.0 L to 4.0 L. Designed to replace the VG series, the all-aluminium 4-valve per cylinder DOHC design debuted with Nissan's EGI/ECCS sequential multi-point fuel injection (MPFI) system. Changes from the VG engine include switching to a timing chain from a timing belt, and relocating the water pump from the outside of the engine to inside the timing cover where the pump is driven by the timing chain. Later versions featured various improvements, such as variable valve timing, and NEO-Di designated VQ engines replace MPFI with direct fuel injection.
The RB engine is an oversquare 2.0–3.0 L straight-6 four-stroke gasoline engine from Nissan, originally produced from 1985 to 2004. The RB followed the 1983 VG-series V6 engines to offer a full, modern range in both straight or V layouts. It was part of a new engine family name PLASMA.
The VG engine is a family of V6 engines designed and produced by Nissan between 1983 and 2004.
The QR family of inline-four piston engines by Nissan were introduced in 2000 and range from 2.0 to 2.5 L in displacement. These motors are aluminum, dual overhead camshaft (DOHC), four-valve designs with variable valve timing and optional direct injection. The engine shares much of its architecture with the YD diesel engine.
The QG engine is a 1.3 L (1,295 cc), 1.5 L (1,497 cc), 1.6 L (1,597 cc) and 1.8 L (1,769 cc) straight-4 piston engine from Nissan. It is a lean-burn aluminum DOHC 4-valve design with variable valve timing and optional NEO Di direct injection.
The KA engines were a series of four-stroke inline-four gasoline piston engines manufactured by Nissan, which were offered in 2.0 and 2.4 L. The engines blocks were made of cast-iron, while the cylinder heads were made of aluminum.
The GA engine is a 1.3 to 1.6 L inline-four piston engine from Nissan. It has a cast-iron block and an aluminum head. There are SOHC and DOHC versions, 8, 12, and 16 valve versions, carbureted, single-point, and multi-point injected versions, and versions with variable valve timing (GA16DE). The GA was produced from August 1987 through 2013. Since 1998, it was only available from Mexico in the B13.
The Mitsubishi Astron or 4G5/4D5 engine, is a series of straight-four internal combustion engines first built by Mitsubishi Motors in 1972. Engine displacement ranged from 1.8 to 2.6 litres, making it one of the largest four-cylinder engines of its time.
The Nissan E series name was used on two types of automobile engines. The first was an OHV line used in the late 1950s and throughout the 1960s. The second was an OHC version ranging from 1.0 to 1.6 litres and was produced from 1981 till 1988. It was replaced by the GA engine series.
The Nissan Z engine is a series of automobile and light truck four-cylinder engines that was engineered by Nissan Machinery, manufactured by the Nissan Motor Company from 1979 through August 1989. All Z engines had 4 cylinders, a total of 8 valves and a single overhead camshaft (SOHC). Displacements ranged from 1.6 L to 2.4 L.The Z series' engine blocks were nearly identical to those of the earlier L Series with the exception of the Z24. While the Z16 and Z18 engines had a deck height similar to the earlier L13/L14/L16/L18 variants, the Z24 had a taller deck height to accommodate a longer stroke. The most notable difference between the Z-series engine and its predecessor was the introduction of a new crossflow cylinder head which reduced emissions by moving the intake ports to the right side of the engine opposite the exhaust ports. This change allows the exhaust port velocity to more effectively scavenge the cylinder and reduce reversion pulses to enhance induction. This change also limits maximum valve lift/lobe lift profiles rendering the cylinder head and valve train configuration undesirable for high-performance uses. The Z series evolved into the NA and KA engines which, along with the smaller CA series, replaced the Z series.
The Prince G-series engine was the company's only straight-four and straight-six engines which began production in 1955. A number of variations were made, with both OHV and OHC heads. A diesel four-cylinder with 1.9 L (1,862 cc) was also built, called the D-6. The G series was used in the Skyline, the Laurel, and the Gloria from the 1950s to the early 1970s.
The HR is a family of straight-3 12-valve and straight-4 16-valve automobile engines with continuously variable valve timing, involving development by Nissan and/or Renault, and also Mercedes-Benz in the case of the H5Ht/M282. The designation of H engine is used by Renault, and M28x by Mercedes-Benz, to classify the family. There are three basic specifications of engine involving variations in engine architecture, or all-new architecture, with 72.2 mm (2.84 in), 75.5 mm (2.97 in) and 78 mm (3.07 in) bore diameter.
The MA is a straight-4 SOHC 0.9 L, 1.0 L, or 1.2 L engine first introduced in 1982 by Nissan, intended primarily for the K10 series Micra/March model. It shares design similarities with the older E engine, with an 8-valve hemispherical cylinder head but differs in that it uses an aluminium cylinder block. Unusually, the specified ignition timing for the MA10 running on the specified 90 RON gasoline was 2 degrees after top dead centre, reflecting a very high flame speed in the compact combustion chambers.
F Renault engine is an automotive internal combustion engine, four-stroke, inline-four engine bored directly into the iron block, water cooled, with overhead camshaft driven by a timing belt, and with an aluminum cylinder head, developed and produced by Renault in the early '80s, making its appearance on the Renault 9 and 11. This engine is available in petrol and diesel versions, with 8 or 16 valves.
The K-Type is a family of inline-4 automobile engines developed and produced by Renault since 1995. This is an internal combustion engine, four-stroke, with 4 cylinders in line bored directly into the iron block, water cooled, with overhead camshaft(s) driven by a toothed timing belt and an aluminium cylinder head. This engine is available in petrol and diesel versions, with 8 or 16 valves.
The R-Type is a family of straight-4 turbocharged diesel engines developed by both Nissan and Renault, and also Daimler in regarding the R9M/OM626 engine. 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. Renault later introduced a higher-powered twin-turbocharged variant producing 160 PS.
The ZR engine is a family of straight-four 16-valve all-aluminum and water cooled gasoline engines with a die-cast aluminum block and variable valve timing developed by Toyota Motor Corporation, produced from 2007. Engines displace from 1.6 to 2.0 liters. Most engines in this family are equipped with Toyota's dual VVT-i technology that optimizes both intake and exhaust valve timing. This engine family is also the first to use Toyota's Valvematic system, first appearing on the Noah and Voxy in 2007 and then the European Avensis in 2009.
The Nissan ZD30 engine family is a 3.0-litre inline-four cylinder diesel engine with a bore and stroke of 96 mm × 102 mm, that replaced the Nissan QD, BD and TD engines. At Renault it also replaced the Sofim 8140 engine and is the only truck diesel engine which remained with Nissan Motors when they sold Nissan Diesel to Volvo trucks in 2007.
The V9X is a common rail 65 degree V6 24-valve DOHC turbo-diesel developed by the Renault-Nissan Alliance, and first installed in the Renault Laguna in 2009. It was subsequently made available for both longitudinal-engine vehicles including Nissan Pathfinder, Nissan Navara, Infiniti FX, Infiniti EX, and Infiniti M and transverse-engine vehicles including Renault Latitude and Laguna Coupé.
The Suzuki K engine family is a series of automobile engines from Suzuki, introduced in 1994. Displacements range from 0.7 L to 1.5 L.
