HOW IT WORKS: Internal Combustion Engine

Gasoline and air mixed together form an explosive mixture the basic job of the engine is to convert this explosive energy into motion to contain the explosion the engine uses a cylinder and fitting snugly within the cylinder. A piston that slides up and down inside  the cylinder an electric spark ignites  the compressed gasoline and air and the  hot gases from the explosion push the  piston downward.

The piston rod is  connected to a crankshaft which converts  the up-and-down motion into rotary  motion the crankshaft then drives the  rear wheels through various machinery  which we'll see later here is a  different perspective on how the piston  drives the crankshaft through the  connecting rod at the top of the  cylinder of the valves which led in the  gasoline and air mixture for increased  power and smoothness.

Modern auto engines  have a number of cylinders driving one  crankshaft gasoline from the tank is  pumped by the fuel pump to the engines  carburetor through the fuel lines the  carburetor mixes the gasoline with air  to form the explosive mixture that  drives the Pistons here's a closer view  of the carburetor .

A linkage connects the  accelerator pedal with a valve in the  carburetor stepping on the gas opens  this valve wider increasing the gas flow  and speeding up the engine easing off on  the pedal reduces the flow and the  engine slows down here on an actual  engine of the counterparts of the fuel  system just diagrammed the fuel pump.

The fuel line from pump to carburetor and  the carburetor itself whether it's air  cleaner removed here is the linkage  connecting the carburetor to the  accelerator pedal  the engines electrical system supplies  the spark that fires the fuel mixture as  the engine rotates it drives a generator  which keeps the car's battery charged  the battery supplies electricity to the  coil which boosts the current to a  voltage high enough to produce a spark  and then sends it through the  distributor to the spark plugs located  in the cylinders.

The distributor  distributes electrical current to the  proper spark plug of the proper time  inside the distributor is a rotor which  as it turns touches a series of contacts  one of which is wired to each spark plug  the points open and closes the rotor  turns interrupting the current to  produce the fuel igniting spark here  again are the major parts of the engines  electrical system ,the generator, the  battery, the booster coil distributor and  spark plugs now looking at an actual engine.

Here is the generator and the  battery together at the rear of the engine of the coil the distributor cap  containing the contact swept by the  rotor the rotor itself and the points  which sometimes need adjustments and  finally in the cylinder heads the spark  plugs  the engine on this model chassis  contains nearly all the parts found in a  working engine let's break it down to  its fundamentals and then build it up  again here's the heart of the engine.

The cylinders and pistons this engine known  as a v8 has two banks of four cylinders  each driving a common crankshaft the  camshaft geared to the crankshaft lifts  and lowers the valves and the cylinders  now the right and left cylinder heads  containing the valves themselves and the  valve lifters the distributor at the  rear of the engine is also driven from....
