POWER SYSTEM Most internal combustion engine are powered with gasoline. However some engine use diesel, electricity, natural gas, solar energy or fuel derived from methanol and ethanol. Most gasoline powered engine works by turning the ignition key that sends electricity current from a battery to a starter motor. The motor turns a disc known as flywheel, which in turn cause the engine crankshaft to resolve. The rotating crankshaft causes pistons, which are solid cylinders that fit snugly inside the engine hollow cylinders, to up and down. Fuel injection system or in other cars, a carburetor deliver fuel vapour from the gas tank to the engine cylinders. The pistons compress the vapour inside the cylinders which is ignited by an electric current flow through a spark plug. The fuel mixture explodes, or combusts, creating hot expanding gases that push the pistons down the cylinder and causes the crankshaft to rotate. The crankshaft is now rotating via the up down motion of the piston, permitting the motor to disengage from flywheel. More soon. Thanks
