The viscosity of oil can be ten times greater than water, increasing the energy required to pump oil for cooling, and reducing the net power output of the engine. Comparing air and water, air has vastly lower heat capacity per gram and per volume (4000) and less than a tenth the conductivity, but also much lower viscosity (about 200 times lower ...
Just like with extreme heat, you shouldn't leave certain things in your car during subzero weather. Freezing temperatures from a harsh arctic blast are expected to affect nearly 300 million ...
A leak in the head gasket - often called a "blown head gasket" - can result in a leak of coolant, the combustion gasses, or both. Blue smoke from the exhaust suggests that excess oil is entering the combustion chambers (although there are other possible causes than a head gasket leak). White smoke from the exhaust suggests that coolant is ...
Litigation has linked it with intake manifold gasket failures in General Motors' (GM's) 3.1L and 3.4L engines, and with other failures in 3.8L and 4.3L engines. One of the anti-corrosion components presented as sodium or potassium 2-ethylhexanoate and ethylhexanoic acid is incompatible with nylon 6,6 and silicone rubber , and is a known ...
Freezing Rain: Rain that falls onto a surface with a temperature below freezing. This causes it to freeze to surfaces like trees, cars, and roads, forming a coating or glaze of ice.
Oil cooling is the use of engine oil as a coolant, typically to remove surplus heat from an internal combustion engine. The hot engine transfers heat to the oil which then usually passes through a heat-exchanger, typically a type of radiator known as an oil cooler. The cooled oil flows back into the hot object to cool it continuously.
Particles in the oil can also cause serious problems with oil pressure. After oil flows through the engine, it returns to the oil pan, and can carry along a lot of debris. The debris can cause problems with the oil pickup screen and the oil pump itself. The holes in the oil pickup screen measure about 0.04 square inches (0.26 cm 2). [6]
Core plugs can also sometimes prevent freeze damage to the motor. During the early stages of the freezing of the engine coolant a freeze plug will sometimes burst or pop out, and thus allow the coolant to exit the engine, before it might expand within the engine during the freezing process and potentially crack the engine block.
