Gasoline engines
- A) Refuel with unleaded gasoline only;
- b) Forced starting of a warm engine by pushing or towing is not permitted. In this case, it is recommended to use an auxiliary battery. Unburned fuel, if ignited, can cause overheating and destruction of the catalyst;
- V) If the engine is difficult to start, do not operate the starter for too long. When starting the engine, fuel is continuously injected. In such cases, you need to find and eliminate the cause of the malfunction;
- G) Keep an eye on the amount of fuel in the tank and do not let it «devastation»;
- d) If misfires are observed, then high engine speeds must be avoided and the malfunction repaired immediately;
- and) Install only those types of spark plugs that are recommended by the vehicle manufacturer;
- h) Carry out a spark test only with the spark plug tip removed, having disconnected the fuel pump power relay before this;
- And) Do not compare cylinders (balance test) by turning off the ignition in the combustion chamber of one cylinder. With such a shutdown, including with the help of a tester to check the operation of the engine, unburned fuel enters the catalyst;
Vehicles with petrol and diesel engines
- To) Do not park your vehicle over dry leaves or grass. The exhaust system in the area of the catalytic converter is very hot and radiates heat even after the engine has been switched off;
- l) Do not apply underbody corrosion protection to parts of the exhaust system;
- m) Do not modify the heat shields of the exhaust system;
- n) When refueling and adding engine oil, make sure that the maximum oil level mark on the dipstick is not exceeded. Excess oil due to incomplete combustion enters the catalyst and can damage the precious metal or completely destroy the catalyst.
