Gasoline engine, the reasons for failure

The engine in the modern car is a complex engineering system. For it to work properly, you need an interconnected work of various elements and assemblies, sensors, etc. Understand this complex system is not everyone's strength. That's why, if the causes engine trouble you are not clear, it is strongly recommended to apply for a service call. In his article "gasoline engine, causes of failure, we will try to describe the main features of engine trouble and to point out the possible causes of engine always starts when the three conditions: 1. that initial rotational momentum, 2. good order intake mixture of fuel and air, 3. Education spark the combustible mixture. If the rotation of the ignition key is no rotation of the engine, then most likely your battery is dead. Problems with the engine depends on the degree of battery power. If neither the electronics nor the lights do not react to the inclusion - so there was a complete discharge of the battery. If the discharge occurred partly depending on its extent, the interior and exterior lighting will not be included, and if they burn, not very. To test you must first check the battery voltage. At voltage less than 10.5 V. should either charge the battery or replace it. Check to see whether the oxidized terminal of the battery. Visually check the cleanliness of terminals. If necessary, clean up and tighten them. Obtain power to the starter could be blocked by signaling. If the reason was the contingency alarm, it must be turned off. Problems in the starter could be the reason that the engine does not scroll. Need to check and tighten electrical connections starter. If there is no result, remove the starter and check the elements. To repair a starter is better to see a specialist. If when you turn the ignition key to position III motor initially begins to rotate, and after some time stops, it means that it is not satisfied the second and third conditions. The reason may be the fault of the fuse or fuel pump relay. If the gasoline pump is faulty, then translated the key to position II you do not hear the sound of fuel pump. Sometimes petrol pump and running, but his power is not enough. Engine starts, but it is unstable, the car did not budge. When a faulty fuel pressure regulator in the ramp will also be a problem with the engine. Diagnostics and maintenance of the pressure regulator should be conducted exclusively in specialized centers and service stations. When a clogged fuel filter engine will not operate at full capacity. Defective electronic component leads to failure of the process of applying to the cylinders of fuel. Due to insufficient air supply can be clogging the air filter or zaledenenie it, as well as fault choke. This all may lead to malfunction of the engine. The reasons for the lack of spark in the engine cylinders may include: failure of spark plugs or bad their condition, faulty ignition coil, wires, ie problems with high-voltage portions of the ignition system, defective electronic control unit, sensors, ie problems with high-voltage portions of the ignition system. So, to sum up the failure petrol engine What could be the cause of the malfunction gasoline engine What should I do to troubleshoot engine will not start Check the fuse fuse fuel pump relay fuel pump check valve relay injector nozzle check is no signal from the sensors check the electrical wires Cold engine runs unevenly or bad start temperature sensor Check sensor Intake air and coolant temperature engine stalls Flag wiring the fuel pump check joints of electrical wires to fuel pump, check the fuse. Clogged fuel filter fuel filter to replace the fuel pump problem fuel pump problem, check valve nozzle Check valve injector faults with the engine idling Depressurization intake system is necessary to check the joints and seals Problems with temperature sensor, if necessary, replace the sensor hot engine will not start fuel pressure in the high-Check fuel pressure. If necessary, replace the regulator pressure fuel line clogged or kinked clean or replace the engine operation after the ignition is turned off Valve depressurize the nozzle check valve nozzle in his article "gasoline engine, causes of failure, we reveal to you the main reasons and indicated the possibility of removing them.
