What should I do if the engine does not ignite?

It depends on what kind of engine you are, if it is diesel, there are two kinds: 1 mechanical engine, 2 electronically controlled engine, 1 mechanical engine, mainly to check: oil circuit, whether the intake air circuit is blocked, starter, (and the most unlikely:

See if the exhaust pipe is blocked) 2 electronically controlled: In addition to the above inspection process, it is also necessary to check the relevant sensors (camshaft position sensor, crankshaft position sensor, intake temperature, pressure sensor, etc.), engine electronic control circuit (electronically controlled fuel injector, electronically controlled oil pump) wiring whether there is a short circuit, open circuit and open circuit of the ground if it is a gasoline engine, it is also divided into two categories: 1 mechanical engine, 2 electronically controlled engine 1 mechanical engine:

Mainly check whether the oil circuit (carburetor, gasoline pump, etc.), whether the intake gas circuit is blocked, whether the distributor is damaged (ignition coil, spark plug, etc.), whether the starter and its circuit are damaged, whether the exhaust pipe is blocked, etc. Electronically controlled: mainly check whether the oil circuit (common rail has oil leakage, whether the electronic gasoline pump is damaged, whether the electronically controlled fuel injector is damaged, etc.) whether the intake air circuit is blocked, whether the ignition module is damaged, whether the spark plug is damaged, and whether the relevant sensors are damaged (camshaft position sensor, crankshaft position sensor, intake air temperature, pressure sensor, etc.) There are also natural gas and electric ones, etc. (but I don't know about these yet), I believe that the engine you encounter should be one of the two I said (this is just a preliminary judgment), according to your additional additions (it is recommended to look at the exhaust pipe first).

1.Whether the battery is out of power, replace the battery; 2.The spark plug is dirty, cleaned; 3. Engine failure, repair!

First, whether the motor is normal and second, whether the oil pump is normal.

The first task of the engine not to start is to find out the cause of the problem and then repair it. The engine failure to start may be due to ignition system failure, fuel** system failure, or battery power failure. If the battery is dead, you can find a car to start the engine.

Batteries are an important part of a car. Without a battery, the car cannot run properly. When the engine is not starting, the electric slip tank can supply power to the electronic equipment of the whole vehicle, and the battery is also responsible for starting the engine.

When starting the engine, the starter, ignition system, fuel system, etc. Basically, they need to be operated, and the operation of these systems cannot be done without electricity. If the battery is dead, the car's engine won't start properly.

When the engine starts, the engine drives the generator to run. When the generator is running, it can charge the battery and also supply power to the electronic equipment of the whole vehicle. Batteries are consumable parts and need to be replaced regularly.

As the number of charge and discharge times increases, the performance of the battery may also deteriorate. During the charging and discharging process, the ions in the battery will move in the electrolyte, and some ions will react with the electrolyte when they move in the electrolyte. As the number of charges and discharges increases, the number of ions in the battery may also decrease, and of course, the performance of the battery will also decrease.

Causes of engine not catching fire The engine not catching fire is one of the most common faults of the car. There are two kinds of fighting scum situations when the fire can't be fired: one is that the starting sound of the starter can be heard, but the engine can't start.

The other is that after twisting the key, there is no sound. The first case is when the starter works, but the engine does not. This is complicated by the fact that it can be caused by one of several failures.

It is rare for two or more failures to occur at the same time, but it cannot be said absolutely. (1) First of all, it may be a circuit or electronic fault. The phenomenon that occurs is very sudden and without warning.

The faults of the circuit are: fuse blowing, high-voltage coil breaking, low-voltage circuit breaking, center ignition wire falling off, splitter head leakage, and spark plug damage. Electronic failure mainly refers to the loss of function of the computer control board.

Oil pump failure, oil circuit failure, oil filter blockage, carburetor failure, nozzle damage, etc. Sometimes it happens that the fuel tank is empty and the owner doesn't know about it. Add a few liters of petrol and you'll be able to solve all the problems.

3) Finally, it can also be a mechanical failure. Common mechanical failures are: time band (chain) breakage, cylinder leakage without pressure, etc.

The second scenario is when even the starter does not work or works barely. At this time, the first thing that needs to be checked is the battery or empty battery. There are many ways to check, but it's best if you have a voltmeter on hand.

Connect the positive and negative poles of the battery, and then twist the key to ignite. If the voltage indication drops below 8 volts at the moment of power on, there must be something wrong with your battery. It doesn't hurt to have a voltmeter, you can replace it with a small 12-volt bulb and a small section of power cord.

The same is true for the method, if the bulb suddenly becomes significantly darker, it is also an indication of battery aging. In many cases, the battery has failed, but the headlights can still be lit. This is not surprising.

Only at the moment of ignition can the performance of the battery be truly tested. Because this is when it has the most load. There's an easy way:

If you look at the outer wall of the battery with the naked eye, if you find that it has expanded and deformed, it means that a new battery is absolutely needed. In addition to the battery, the reason why the starter does not work can be a damaged ignition switch, a damaged ignition relay, or a damaged starter itself. Also, check the ground line and fuse.

The solutions to the engine not catching fire are: power off and restart, wire, battery replacement, etc.

1. Power off and restart

Cars are also like mobile phones, shutting down and restarting can solve a lot of problems! If the car doesn't catch fire, you can also try it first and restart it after the power is off in the middle of the spring. When you find that it can't ignite, open the front cover of the car and find the battery.

Generally speaking, there is a buckle on the positive and negative poles of the battery, which can be broken by hand without the help of tools. After breaking the buckle, the whole car will be powered off, and if you install it again after a minute, it will be equivalent to restarting it again. At this time, we will try to see if we can start a fire.

2. Take the wire

Riding wires is also what we commonly call "crossing the river dragon". When using, you need to find another car to help, connect the batteries of the two cars, the red wire is connected to the positive pole, and the black wire is connected to the negative pole. You must remember that "red is positive and black is negative", and you must not make a mistake!

After picking it up, start the car that helps first, and then ignite the car that loses power, and it can be successfully ignited in a few minutes.

3. Change the battery

The battery is a wearing part of the car, only has a life span of years, even if there is no problem, it must be replaced when it expires. Of course, it is a safe thing to go to the 4S store to change the battery, but the charge is a bit high! Roadside auto repair shops can also be replaced, which are generally cheaper.

The reason why the engine won't catch fire

1. There may be problems with the oil supply system of the automobile engine, such as the oil circuit is blocked due to low pressure, the oil supply pipeline of the engine is loose and leaking, the technical condition of the injector is not good, and the timing angle of the injector is wrong.

2. It may be that the starting device of the engine is faulty, such as the poor contact of the power supply or electromagnetic switch of the engine start, and the slippage of the clutch of the automobile engine.

3. The cylinder gasket of the cylinder in the automobile engine is damaged, resulting in cylinder leakage, and the engine cylinder is not tightly closed and leaking, which will lead to insufficient pressure of the engine cylinder, which will affect the start of the automobile engine.

If the engine does not catch fire, you must first find the cause of the failure, and then repair it. The engine may not start because of a faulty ignition system, it may be due to a faulty fuel supply system, or it may be due to a dead battery. If the battery is out of power, you can find a car to start the engine.

The battery is an important part of the car, and if there is no battery, the car cannot operate normally.

When the engine is not started, the battery can supply power to the entire car's electronic devices, and the battery is also responsible for starting the engine.

When starting the engine, the starter, ignition system, fuel supply system, etc. all need to be operated, and the operation of these systems is inseparable from electricity.

If the battery is dead, the car's engine will not start properly.

After starting the engine, the engine will drive the generator to run, and the generator can charge the battery when it is running, and can also supply power to the electronic equipment of the whole car.

The battery is a wearing part that needs to be replaced regularly, and the performance of the battery will also decrease as the number of charging and discharging times increases.

During charging and discharging, the ions in the battery will move in the electrolyte, and some ions will chemically react with the electrolyte when they move in the electrolyte.

As the number of charge and discharge increases, the number of ions in the battery will also decrease, so the performance of the battery will also decrease.

The engine does not ignite, at this time, first of all, we check that the oil supply system is abnormal, and secondly, check the ignition system and the exhaust lead nuclear system and other air intake systems.
