Electrical cord for powering a block heater. A block heater is used in cold climates to warm an engine prior to starting. They are mostly used for car engines; however, they have also been used in aircraft engines. The most common design of block heater is an electrical heating element embedded in the engine block.
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, 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.

When the engine's surroundings are cold, the air's thermal energy – that it has previously received from the starter motor's compression work – is absorbed by the cylinder head and engine block, and eventually transferred to the air surrounding the engine. When the temperature of the air surrounding the engine comes below a certain value ...
In an internal combustion engine, the engine block is the structure that contains the cylinders and other components. The engine block in an early automotive engine consisted of just the cylinder block, to which a separate crankcase was attached. Modern engine blocks typically have the crankcase integrated with the cylinder block as a single ...
The contact breaker is operated by an engine-driven cam.On an engine with a distributor, the contact breaker can be found beneath the distributor cap.The position of the contact breaker is set so that it opens (and hence generates a spark) at exactly the optimum moment to ignite the fuel/air mixture.
This burst of electricity then travels to the spark plug (via high tension leads), where it ignites the air-fuel mixture in the combustion chamber. On most overhead valve engines , the distributor shaft is driven by a gear on the camshaft , often shared with the oil pump ; on most overhead camshaft engines , the distributor shaft is attached ...
Tonawanda Engine is a General Motors engine factory in Buffalo, New York. The plant consists of three facilities totaling 3.1 million square feet (290,000 m 2 ) and sits upon 190 acres (77 ha).
VR5 and VR6 engines are very compact and light, having a narrow V angle which allows a single cylinder block and cylinder head. These engines use a single cylinder head so are technically a straight engine with the name "VR" coming from the combination of German words “Verkürzt” and “Reihenmotor” meaning “shortened inline engine”.
