The M115 engine family was a straight-4 automobile engine from Mercedes-Benz that was produced during the 1970s. This engine was a successor from the M121 and was replaced by the M102 engine. This engine is modified from the M121 by adding a five-bearing crankshaft. [2] The same engine was produced in several versions with differing volume, compression, and horse power according to its application.

The BMW M10 is a SOHC inline-4 petrol engine which was produced by BMW from 1962-1988. It was the company's first four-cylinder engine since the BMW 309 ended production in 1936 and was introduced in the New Class sedans.
The Ford Cologne V6 is a series of 60° cast iron block V6 engines produced by the Ford Motor Company from 1962 to 2011 in displacements between 1.8 L; 110.6 cu in (1,812 cc) and 4.0 L; 244.6 cu in (4,009 cc). Originally, the Cologne V6 was installed in vehicles intended for Germany and Continental Europe, while the unrelated British Essex V6 was used in cars for the British market. Later, the Cologne V6 largely replaced the Essex V6 for British-market vehicles. These engines were also used in the United States, especially in compact trucks.
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.
Toyota Motor Corporation's M family of engines were a longitudinally mounted straight-6 engine design. They were used from the 1960s through the 1990s. All M family engines were OHC designs. While the M family was born with a chain-driven single camshaft it evolved into a belt-driven DOHC system after 1980. All M family engines used a cast-iron block with an aluminum cylinder head, and were built at the Toyota Kamigo plant in Toyota City, Japan.
The Ferrari Colombo Engine was a petrol fueled, water cooled, carburetted 60° V12 engine designed by Gioacchino Colombo and produced in numerous iterations by Italian automaker Ferrari between 1947 and 1988. The maker's first homegrown engine, its linear successor is the Lampredi V12, which it far outlived, the last Lampredi being made in 1959.
The Mitsubishi Orion or 4G1 engine is a series of inline-four internal combustion engines introduced by Mitsubishi Motors in around 1977, along with the Astron, Sirius, and Saturn. It was first introduced in the Colt and Colt-derived models in 1978. Displacement ranges from 1.2 to 1.6 L.
The Mitsubishi 4G9 engine is a series of straight-4 automobile engines produced by Mitsubishi Motors. All are 16-valve, and use both single- and double- overhead camshaft heads. Some feature MIVEC variable valve timing, and it was the first modern gasoline direct injection engine upon its introduction in August 1996.
The Nissan H series of automobile engines is an evolution of the Nissan "R" engine which was based on the 1.5-liter, three-main bearing "G" engine used in the 1960s. Both inline-four and inline-six versions were produced. It is a pushrod OHV design with iron block, early models with an iron head, later models with aluminum head. Versions of this motor have been used in many Nissan autos and forklifts, well into the eighties and a version called H20II was in production until 2003. The SD diesels are based on this series of motors
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 M102 engine family is a inline-four gasoline automobile engine family built by Mercedes-Benz in the 1980s and early 1990s. It is a relatively oversquare engine with a large bore and short stroke compared to the M115 engine which was used during the same timeframe.
The M110 engine family is a DOHC crossflow cylinder head design with 2 valves per cylinder straight-6 automobile engine made by Mercedes-Benz in the 1970s and 1980s.
The OM615 was a inline-four diesel engine made by Mercedes-Benz. A successor to the OM621, it was sold in early 1968 in two versions: 1,988 cc (2.0 L) and 2,197 cc (2.2 L) engine.
The OM617 engine family is a straight-5 diesel automobile engine from Mercedes-Benz used in the 1970s and 1980s. It is a direct development from the straight-4 OM616. It was sold in vehicles from 1974 to 1991. The OM617 is considered to be one of the most reliable engines ever produced with engines often reaching over 1,000,000 km (620,000 mi) without being rebuilt and is one of the key reasons for Mercedes' popularity in North America in the 1980s, as it was powerful and reliable compared to other automotive diesels of the time. It is also a very popular choice for the use of alternative fuels, mainly straight or waste vegetable oil and biodiesel, although the use of these fuels may cause engine damage over time if not processed properly before use.
The Mercedes-Benz M104 is a automobile straight-six engine produced from 1988 through 1999. It has a double overhead cam design with 4 valves per cylinder, and used a crossflow cylinder head. It replaced the M103 and was replaced by the M112 V6 starting in 1997. The bore spacing on all M104 engines is the same as M103 engines.
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 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 Volvo Modular Engine is a family of straight-four, straight-five, and straight-six automobile piston engines that was produced by Volvo Cars in Skövde, Sweden from 1990 until 2016. All engines feature an aluminum engine block and aluminum cylinder head, forged steel connecting rods, aluminum pistons and double overhead camshafts.
The Mercedes Benz M180 engine was a 2.2 L; 134.0 cu in (2,196 cc) single overhead camshaft inline-6 cylinder engine introduced at the Frankfurt Motor Show in April 1951 to power the company's new 220 (W187). It was the first engine with a cylinder bore greater than its stroke that Mercedes had installed in a production car, while using a reverse-flow cylinder head.
The M111 engine family is a straight-4 automobile engine from Mercedes-Benz, produced from 1992 to 2003. Debuted in the 1992 Mercedes-Benz E-Class (W124), this engine family is relatively oversquare and uses 4 valves per cylinder. All engines in the family use a cast iron engine block and aluminum alloy cylinder head.
The Mercedes-Benz M121 engine was a 1.9 liter single overhead camshaft inline four-cylinder engine introduced by Mercedes in 1955 and used in various model lines during the 1950s and 1960s. Originally rated at 56 kW at 5500 rpm, it replaced the 1.8 liter M136 introduced in 1935, offering improved performance over the M136's side camshaft design.
