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 ...
The engine temperature on modern cars is primarily controlled by a wax-pellet type of thermostat, a valve that opens once the engine has reached its optimum operating temperature. When the engine is cold, the thermostat is closed except for a small bypass flow so that the thermostat experiences changes to the coolant temperature as the engine ...
The Mercedes-Benz M272 engine is an automobile piston V6 engine family used in the 2000s (decade). Introduced in 2004, it is based on the M112 V6 introduced in 1998. All M272 engines have aluminum engine blocks with a 90° V-angle with silicon/aluminum lined cylinders. The aluminum DOHC cylinder heads have 4 valves per cylinder.
Some of that coolant can be diverted through the heater core to give some engine heat to the cabin, or adjust the temperature of the conditioned air. A heater core is a small radiator located under the dashboard of the vehicle, and it consists of conductive aluminium or brass tubing with cooling fins to increase surface area. Hot coolant ...
However, once water boils, it is an insulator, leading to a sudden loss of cooling where steam bubbles form. Steam may return to water as it mixes with other coolant, so an engine temperature gauge can indicate an acceptable temperature even though local temperatures are high enough that damage is being done. An engine needs different temperatures.
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 ...
It was found that coolant temperature increased by almost 20 °C (36 °F) during the first four hours, regardless of the initial temperature. Four tests were run at ambient temperatures ranging from −29 to −11 °C (−20 to 12 °F); continued use of the heater for up to two hours more only further increased the temperature by up to 3 °C (5 ...
The F30 sedan debuted at the 2012 Geneva Motor Show in March 2012 [12] and was the first of the sixth generation 3 Series models to go on sale. [13] Early models included the 328i and 335i and (post LCI) later models included the 330i and 340i.
