2013 MOTORCYCLE: OCCURRENCE OF COMBUTION PROCESS

OCCURRENCE OF COMBUSTION PROCESS
In this third post about the authors describe the material explanation of the combustion process in the engine motorcycles. as always please read my arikel and if it should copy the copy please but do not you publish the article back to your website / blog. remember was the confident use your idea to publish a quality arikel, "NOT THAT COPIES".
Fuel-air mixture is sucked into the cylinder entry. Subsequently compressed by the upward movement of the piston. The mixture was compressed, then burned by the spark plug. There was an explosion / expansion that would push the piston down, then rotate the crankshaft through the connecting rod, up and down motion of the piston is converted into motion by the crankshaft and piston channeled through the gears. In other words: When the piston is at top dead center (TDC), intake valve opening and sucked the fresh fuel mixture into the cylinder. At bottom dead center (BDC) intake valve closing and during a step back to TMA gas will be compressed. Ignition is instantaneous at TDC, giving rise to an increase in the temperature and pressure of the gas quickly. Then gas is expanded during the working steps, until padaTMB exhaust valve opens, and gas will be pushed out through the hole
exhaust. With the move to four (from BDC to TDC) will be excluded from all of the gas cylinder. Spark plugs produce sparks of fire between the electrodes for burning a mixture of air and fuel at the time of receiving the high-voltage spark from the ignition coil. When the air-fuel mixture to explode, rising temperatures around 25000C and pressure to 50 kg/cm2 in the combustion chamber. Injection combustion occurs when the fuel injector mengabutkan with high pressure, so that the fuel burned by hot air, and the pressure in the room will rise to 70-90 kg/cm2. The process begins when the pistons compress the air, at the end of the compression stroke fuel carburetion is exactly happening. At the time of the temperature and the air pressure is very high, the fuel is sprayed into the combustion chamber. Combustion occurs without using pieces of fire igniter.
