The role sensor is used to contain oxygen in the gas (exhaust) of the cylinder pai chu. the vehicle computer controls the intake of air and fuel according to the han yang liang of exhaust gas, so that the fuel can be fully burned, and bu zhi yu is wasted and produced, at the same time, the air will not waste valuable cylinder volume.
1 , The use of Oxygen Sensors: oxygen sensor is an important element of Fuel Injection closed loop control of electronic control engine, in order to achieve emissions regulations and to improve vehicle fuel consumption, before the oxygen sensor is mainly used to test cylinder combustion after the emissions of the oxygen content in and oxygen too much, the gas mixture had thin, fuel too little, lambda> 1 (λ for actual fuel-air ratio and theory fuel than ratio ), at this time of the oxygen sensor feedback voltage to the ECU, ECU Based on mixture had dilute the calculation results and then increase the quantity, or reduce the quantity
2 ,The oxygen sensor is at any time to detect the exhaust gas pump, and feedback the engine to the engine at any time, the engine computer, as the signal reflects hun he qi, is in time for the feedback signal to be tuned, reduce injection time.
3 ,Effects of oxygen sensors on cars: when the oxygen sensor huai diao, it will fuel the injection when it is not in fuel, when it comes to injection, it doesn't fuel, causing the engine to fall, shake, and discharge the geng gao, when it's serious, it causes the engine to knock.
