| Three element catalyst attention problem |
| In view of the reasons for the early failure of the three element catalyst, we should pay attention to the following matters: 1 do not use leaded gasoline. 2 do not operate in a long run (open loop control). 3 do not let the engine speed up and down. 4 ignition time is not too late. 5 long time to start. 6 don't pull out the high pressure line for a long time. 7 measurement of cylinder pressure, to pull off the fuel pump to control the joint, so as to stop the injector to the cylinder injection. 8 when the cylinder is found to be bad, should stop the inspection, troubleshooting. 9 avoid the mixed gas partial concentration of many factors, such as the fuel injector is not strict, the fuel pressure regulator failure (oil pressure is too high), oxygen sensor failure, air flow sensor failure, etc.. 10 catalytic converter as long as the correct use, generally do not need maintenance, so do not disassemble, if the replacement must be matched with the engine. |
