In view of the reasons for the early failure of the three-way catalytic converter, the following matters should be paid attention to when using:
● Do not use leaded gasoline.
● Do not run rapidly for a long time (open loop control state).
● Don’t let the engine speed go fast or slow.
● Do not fire too late.
● Can’t start for a long time.
● Do not pull out the high-voltage line for a long time to test the fire.
● When measuring the cylinder pressure, unplug the central control connector of the fuel pump to stop the fuel injector from injecting fuel into the cylinder.
● When it is found that the cylinder is not working well, it should be stopped in time for inspection and troubleshooting.
● Avoid many factors that cause the mixture to be rich, such as the fuel injector is not closed tightly, the fuel pressure regulator fails (the oil pressure is too high), the oxygen sensor fails, and the air flow sensor fails.
● As long as the catalytic converter is used correctly, it generally does not need maintenance, so it should not be disassembled casually. If it needs to be replaced, it must be matched with the engine.
