How to use the car with a catalytic converter in the exhaust system

To avoid damage to the oxygen concentration sensor (oxygen sensor) and a catalytic converter it is necessary to follow these instructions:

Always refuel with unleaded petrol.

If an error was flooded leaded fuel, it is necessary to replace the exhaust manifold and the catalytic converter. Before installing the new elements of the exhaust system at least 2 times to be completely fill the fuel tank with unleaded gasoline.

Starting with a warm engine speed or towing is not allowed. Use electrical cable to start the engine. Unburned fuel at ignition can lead to overheating of the catalytic converter and its subsequent destruction.

You should avoid frequent cold starts, one after the other. Otherwise, in the catalyst collected unburned fuel burns explosively upon heating, wherein the converter is damaged.

In case of difficulty in starting the engine do not let the starter run for a long time, as occurs during start-up fuel injection. Should find and fix the problem, then start the engine.

When disruptions in the ignition system to determine the cause of the problem, do not allow the injection of fuel when starting the engine.

Do not check for spark with spark plug removed.

It is impossible to hold the balance test of high voltage ignition wires disconnecting one of the cylinders. If you turn off the high-voltage ignition cables separate cylinder - even with a special tester - unburned fuel to enter the catalytic converter.

When disruptions in the ignition system of the engine, avoid high engine speeds. Correct the problem as soon as possible.

Do not leave your car on dry leaves or grass. The exhaust system in place of the catalytic converter has a very high temperature and radiation of heat occurs even after turning off the engine.

When filling or topping up the engine oil must be ensured that the maximum oil level dipstick is not exceeded. Otherwise, too much oil can get into and damage the catalyst coating or totally destroy it.
