How Car Engines Work

In this post ill show a tell you how car engines work .
­­Have you ever opened the hood of your car and wondered what was going on in there? A car engine can look like a big confusing jumble of metal, tubes and wires to the uninitiated.
A gasoline engine operates on the principle of combustion. A fuel/air mixture is pulled into a cylinder, the cylinder is then closed off and the piston is thrust upward to create compression. A spark is introduced to ignite the mixture to create combustion to thrust the piston downward in the engine block

There are a number of pistons inside an engine depending on the design, 4 to 12 cylinders usually. The pistons are connected to a crankshaft through a connecting rod. Pistons fire consecutively to rotate the crankshaft inside the engine block. The oil pump pushes oil through the oil filter and then supplies oil to vital engine parts including the crank and camshaft, cylinder walls and piston rings, valve train, cam lifters and the timing gears or chain. Motor oil is used to lubricate and cool internal engine parts. Oil is pumped up through the engine, then returns to the bottom of the engine and is gathered in the oil pan.

The cylinder head is connected to the top of the engine block and allows air/fuel mixture and exhaust into and out of the cylinder block. The cylinder head has the duty of holding the air/fuel mixture charge inside the cylinder as it combusts, forcing the piston downward. The cylinder head is connected to the engine block using head bolts, using a head gasket to seal both parts.
