Attention! However, the cause of the malfunction must be eliminated at the certified SSSS as soon as possible.
A fuel injection engine with a catalytic converter and an oxygen sensor works properly if only unleaded gasoline is used. Leaded gasoline in a short time puts these elements out of action, smoky exhaust appears, fuel consumption increases sharply and the dynamics of the car worsens.
Attention!
- The catalytic converter is an expensive component that ensures environmental protection. The catalytic converter can be damaged by misfires in the engine cylinders (external manifestation - interruptions in the operation of the engine and twitching when the car is moving), because unburned fuel in the cylinders will ignite in the converter and the temperature in it will rise sharply, which will cause thermal damage to the catalytic converter element. Electronic engine control units have the function of protecting converters from misfiring. If a misfire occurs in one or two cylinders, the warning lamp «Engine» turns on in a flashing mode, the fuel supply is turned off in the cylinders in which gaps are detected, after which the signaling device «Engine» stays on until the end of the trip. If misfiring occurs, immediate action must be taken to eliminate them.
- Cars equipped with catalytic converters can only be started by towing when the engine is cold. It is preferable to start the engine using a different battery or an external 12 volt power source, and in no case use the starter to move the car.
- The vehicle is equipped with a exhaust pipe with a catalytic converter having a high operating temperature, therefore it is strictly forbidden to place and store flammable materials and objects in the engine compartment (rags, paper, etc.) to prevent possible fire.
