BMW is recalling more than 720,000 vehicles due to an issue with the water pump's electrical connector that could potentially lead to a fire. The National Highway Traffic Safety Administration ...
Tank's solution for the BMW 139 was to use an engine-driven fan behind an oversized, flow-through hollow prop-spinner open at the extreme front, blowing air past the engine cylinders, with some of it being drawn through S-shaped ducts over a radiator for oil cooling. However this system proved almost impossible to operate properly with the BMW ...
Dealers will inspect and replace the water pump and plug connector as necessary, and install a protective shield for free, the U.S. auto safety regulator said. ... The NHTSA also said that BMW was ...
Heater core (arrowed) in the partially disassembled dashboard of a BMW E32. The internal combustion engine in most cars and trucks is cooled by a water and antifreeze mixture that is circulated through the engine and radiator by a water pump to enable the radiator to give off engine heat to the atmosphere. Some of that coolant can be diverted ...
The Roman hypocaust is an early example of a type of radiator for building space heating. Franz San Galli, a Prussian-born Russian businessman living in St. Petersburg, is credited with inventing the heating radiator around 1855, [1] [2] having received a radiator patent in 1857, [3] but American Joseph Nason and Scot Rory Gregor developed a primitive radiator in 1841 [4] and received a number ...
Cooling system regulation includes adjustable baffles in the air flow (sometimes called 'shutters' and commonly run by a pneumatic 'shutterstat'); a fan which operates either independently of the engine, such as an electric fan, or which has an adjustable clutch; and a thermostatic valve or a thermostat that can block the coolant flow when too ...
The Liberty L-12 is an American water-cooled 45° V-12 engine, displacing 1,649 cubic inches (27 L) and making 400 hp (300 kW), designed for a high power-to-weight ratio and ease of mass production. It was designed principally as an aircraft engine and saw wide use in aero applications .
Oil circulation system Gerotor type oil pump from a scooter engine. The oil pump is an internal combustion engine part that circulates engine oil under pressure to the rotating bearings, the sliding pistons and the camshaft of the engine. This lubricates the bearings, allows the use of higher-capacity fluid bearings, and also assists in cooling ...
