Valve located on the cylinder head on each vehicle is shaped like an umbrella. Valve is divided into 2 work, the first is the valve and the second entry is the waste valve. Valve in its function is to include a mixture of air and gasoline that have been shaped into a cylindrical fog machine. While waste valve is the valve that serves to remove the combustion gases after the piston compress. Each vehicle has a number of valves different. In the small cars made in Japan tahun80an, usually the number of valves in each cylinder there are 3 valve. However, today's cars are now adopted at 4 valves per cylinder. This is done to enhance the volumetric efficiency so that utilization can be more effective fuel and power for the greater dihasilkanpun cylinder engine together. So that when a 4-cylinder engine has a valve in the number and total waste of 16. as well as motors, the motors were cc usually have 4 valves. 2 in and 2 waste. Valves are usually made of heat resistant steel and stainless (Stainless Steel). We're doing the compression, the valve serves to close the hole or channel in the cylinder. At the end of combustion, waste valve to drain immediately open the rest of the combustion gases to the exhaust manifold. After the disposal process is complete, the piston will do steps suction and suction-valve was opened to include a mixture of air and gasoline that has clouded towards the engine cylinder. Each valve of a cylinder to open and close movement once for every two crankshaft rotation (crankshaft).
Berkonstruksi engine valve on the side, these valves are driven by a pressure valve is driven by the boss. While the engine valve system that applies above (SOHC / DOHC), a pressure valve and pressure valve stems. Having raised so terlepasdari place holder, the valves are returned to their original position by a spring. At the time of opening, the valves will be lifted from the holder of 5/16-3/8 inch. Also the valve can be said to work hard. Like, if the engine spinning 7500 rpm, the valve opened and closed more than 60kali/detik. If the engine was encouraged to 10,000 rpm, the valve is forced open and close to more than 80 times / second. Valve temperature can reach 700 degrees Celsius
