Three way catalytic converter is the most important, cleaning device is installed in the automobile exhaust system in the machine, it can be from the vehicle exhaustCO, HC and NOx and other harmful gases through oxidation and reduction into harmless carbon dioxide, water and nitrogen. Cairo solar term door body said that because of this catalytic converter can also be conversion of harmful substances in exhaust gas harmless substances. With the increasingly stringent environmental protection requirements, more and more auto install exhaust gas catalytic converterand oxygen sensor device.

Cairo said the throttle body throttle opening angle is determined through the air intake throttle control accelerator, so as to adjust the oil feeding amount of equipment. Common ground says, the accelerator pedal is stem what of? Control of accelerator? Wrong, in fact is to control the throttle. The deeper the throttle pedal,the larger the angle, the intake air quantity is more, the oil inlet amount is much,which is why it is considered the cause of accelerator.

Cairo said the throttle body injector is actually a simple electromagnetic valve, when the electromagnetic coil is energized, resulting in suction needle be attracted, openhole nozzle, fuel between the needle head shaft needle and jet hole annular gap is ejected at a high speed, the formation of fog, fully to the combustion and decline,the power is not timely cleaning maintenance three yuan will result in the vehicle's fuel consumption increase, excessive exhaust emissions. Jam will make three yuantemperature increases from hundreds of degrees to one thousand degrees (normalis 810 degrees Celsius), resulting in three yuan high temperature sintering andcompletely damaged. Will make the exhaust pipe burn red, but also may cause the vehicle ignition.
