Not every motorist can independently determine the malfunctions of a car engine and independently diagnose what happened to him. However, any car owner must have at least minimal knowledge of this issue in order to know the cause of engine breakdown.
Instructions
Step 1
Winter has come, and the engine started to start every other time or stopped functioning altogether? Most likely, the fact is that the operation of the system, which is responsible for preheating, is disrupted, or it is your own fault that you are using it incorrectly. Or the reason for this was the paraffinization of the fuel. This is what they call it hardening due to cold - it is for this reason that the engine cannot work normally. Also check that the cold start mechanism is working properly.
Step 2
Engine operation does not depend on temperature and weather conditions at all - do it malfunction during heat and frost? This means that the required speed of rotation of the starter of the car is violated. If this is not the case, insufficient compression is possible (this is the maximum allowable force pressure in the combustion chamber, the main purpose of which is to compress the air and, as a result, increase the pressure). Of course, regardless of external conditions, the car will not start if there is no fuel in the fuel tank. Poor-quality fuel (it is polluted or there is air in it) is also a significant reason for a car engine malfunction. The reason may be the appearance of excess resistance in the system responsible for the fuel supply.
Step 3
Does the engine start steadily, but with great difficulty? The procedure for starting the engine may be violated or a breakdown of the starter or battery has occurred. Check the correct adjustment of the valve clearances, as well as the springs (they may not be too tight or broken), as well as the serviceability of the car injectors. The cleanliness of the air filters installed in the vehicle can also affect engine performance. External fuel leakage or its leakage into the sump of a car are also common causes of engine malfunctions.
