Who and what year was the four stroke engine invented.
What is the purpose of the crankshaft,camshaft,vavles collects(keepers),vavle sterm seals,head gasket,pistons,piston rings name them all, cambelt,flywheel?
What is the bore and stroke.
What i am looking for is a good explaination about each component, use you-tube for videos,
The four stroke engine needs for four strokes to make power. The four cycles to make power are as follows:
Induction- The piston starts at top dead center. The piston then travels down the cylinder and as this happens a mixture of fuel and air is inducted into the cylinder. (induction valve open)
Compression- The piston now at bottom dead center is pushed up. As this happens the mixture of air and fuel is compressed. (both valves closed)
Power- The compressed mixture of fuel and air is ignited by the spark plug and the explosion causes the piston to travel downward. (Both valves closed)
Exhaust- The piston travels upward and the gas produced from the explosion is pushed out the combustion chamber. (Exhaust valve open)
Nikolavs August Otto from Germany invented the the 4 stroke principle in 1876.
The crank shaft transfers the pistons vertical motion into a torque motion. The camshaft controls when the valves open and close. The valve stem seals prevents oil entering the fuel and air mixture. The head gasket seals the head on the block. The piston is the component being forced down because of an explosion. That is what makes the power. The Piston rings have 3 purposes. The first ring is to keep compression in the cylinder, the 2nd ring is to remove excess oil from the cylinder on the downstroke. The oil ring stores a layer of oil for lubrication. The cambelt keeps the cams in time with the crank. The flywheel bolts to the back of the crank and holds to momentum of the engine. It also provides a place for the clutch to engage to the engine and transfer power to gearbox.
Lets try and get some pictures in with your writing
