The N52 was the first water-cooled engine to use magnesium/aluminium composite construction in the engine block. [1] It was also listed as one of Ward's 10 Best Engines in 2006 and 2007. [2] [3] [4] In European markets, the N52 began to be phased out in favor of its direct injected version, the BMW N53 in 2007. Markets such as the United States ...
Several markets outside Europe only offered a small subset of models in the estate body style. In the United States and Canada, the only estate model available prior to 2007 was the 325xi, [24] and then the 328i and 328xi from 2007 onwards. The Australian market received only a handful of models which included the 320i, 320d and 323i until the ...
The worst problem met in air-cooled aircraft engines was the so-called "shock cooling", when the airplane entered in a dive after climbing or level flight with throttle open, with the engine under no load while the airplane dives generating less heat, and the flow of air that cools the engine is increased, a catastrophic engine failure may ...
A typical engine coolant radiator used in an automobile. Radiators are heat exchangers used for cooling internal combustion engines, mainly in automobiles but also in piston-engined aircraft, railway locomotives, motorcycles, stationary generating plants or any similar use of such an engine.
Waterless coolant is most prominently used in the cooling systems for motorsports, classic car, ATVs, UTVs, snowmobiles and older cars. [4] Older cars often have non-pressurized cooling systems, and the water-based coolant can boil and overflow. Traditionally, this issue has been solved by topping off the radiator with water. This dilutes the ...
A coolant is a substance, typically liquid, that is used to reduce or regulate the temperature of a system. An ideal coolant has high thermal capacity, low viscosity, is low-cost, non-toxic, chemically inert and neither causes nor promotes corrosion of the cooling system. Some applications also require the coolant to be an electrical insulator.

Also in 2016, a 3-cylinder engine was used for the first time in a 3 Series. The M3 version (designated F80, the first time an M3 has used a separate model designation) was released in 2014 and is powered by the S55 twin-turbo straight-6 engine. Production ended in 2019 with the end of F31 Touring production in June. [20] [21]
