What is the reason why the Cummins engine does not catch fire Anyone who knows Cummins, please point

The engine does not catch fire and is one of the most common faults in cars. There are two situations when the ignition is not ignited: one is that the starter can be heard, but the engine cannot 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: fuses.

Burnout, high-voltage coil break, low-voltage circuit break, center ignition wire off, fire splitter leakage, spark plug.

Damage. Electronic failure mainly refers to the loss of function of the computer control board.

2) Then there is the failure of the oil circuit. The stalling caused by oil circuit failure is often a symptom of engine weakness and refueling pedal stepping on cotton. Oil circuit failures may occur in the following areas: oil pump failure, oil circuit failure, oil filter blockage, carburetion.

Failures, nozzle damage, and more. 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 battery. There are many ways to check if you have a voltmeter on hand.

That's for the best. 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. Another simple way is to look at the outer wall of the battery with the naked eye, and 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.

1) Look at the front fuse box, there is an ECV fuse, if he is broken, the engine computer department is working!

2) If it is not broken, replace the diesel filter, and there is a solenoid valve under the oil pump to see if there is a 5V voltage!

3) There are 2 red buttons near the battery to see if it is a passage!

4) The oil rail comes to the oil pipe to see if the oil pressure is enough!

That's the general situation when Cummins won't start! You see if it's useful to you.

There are many reasons why it is not good to start, such as:

The battery is low and the starting speed is low.

Starter motor failure.

There is air in the low-pressure oil circuit.

The oil transfer pump is faulty, and the check valve is not closed tightly.

The fuel injection pump is aging and leaking, and the fuel supply is insufficient.

The governor is stuck, the rack is stuck, and the throttle is stuck.

The oil supply time is not accurate.

The fuel injector is aging, stuck and poorly atomized.

The cylinder is worn and the cylinder pressure is insufficient.

The valve is not closed tightly.

The system reports an error.

Pull the cylinder and hold the shaft. ......

The above analysis is for reference.

The Cummins engine doesn't start well.

Hello. There are many reasons for poor starting, such as: insufficient battery power and low starting speed.

Starter motor failure. There is air in the low-pressure oil circuit. The oil transfer pump is faulty, and the check valve is not closed tightly.

The fuel injection pump is aging and leaking, and the fuel supply is insufficient. The governor is stuck, the rack is stuck, and the throttle is stuck. The oil supply time is not accurate.

The fuel injector is aging, stuck and poorly atomized. The cylinder is worn and the cylinder pressure is insufficient. The valve is not closed tightly.

The system reports an error. Pull the cylinder and hold the shaft. ......

Spray starter fluid.

If you don't spray, you can't start it.

There is no explosive power, 1. Your inability to hit the phenomenon may be mainly caused by excessive carbon accumulation in the idle motor, air intake, intake valve and combustion chamber. 2. Because of the excessive carbon deposition and dirt in the air intake, the cross-sectional area of the air passage changes, resulting in the mixture being too thick or too thin, making the combustion abnormal or the engine shaking or even unable to start after starting. Or because there is a problem with the fuel injector, there is leakage or too much carbon, resulting in the mixture being too thin during start-up, which makes it difficult to start.

3. If the carbon canister or carbon canister solenoid valve fails, it will also cause it to be difficult to start.

Summary. Hello, glad for your question, first of all 1 you look down the front fuse box There is an ECV fuse fused no if he is broken if the engine computer department works !

2) If it is not broken, replace the diesel filter, and there is a solenoid valve under the oil pump to see if there is a 5V voltage!

3) There are 2 red buttons near the battery to see if it is a passage!

4) The oil rail comes to the oil pipe to see if the oil pressure is enough!

That's the general situation when Cummins won't start! You see if it's useful to you.

What is the reason why the Cummins engine does not catch fire Anyone who knows Cummins, please point me to get lost

Hello, I have seen your question, and I am sorting out the answer, please wait a while Hello, I'm glad for your question, first of all, 1 you look at the front fuse box There is an ECV fuse fused if he is broken The engine computer department works! 2. If it is not broken, it will be replaced with a diesel filter, and there is a solenoid valve under the oil pump to see if there is a 5V voltage! 3. There are 2 red buttons near the battery to see if the hail is the pathway!

What is the reason why a Cummins engine will not ignite? What is the reason why a Cummins engine will not ignite? Cummins belongs to the automotive engine brand.

The reasons why a Cummins engine fails to ignite include running out of fuel, faulty shut-off valve, clogged inlet, faulty injector, etc. The following is a detailed introduction about the automobile engine: 1. Overview:

The automobile engine is the device that provides power for the car, which determines the power, economy, stability and environmental protection of the car. According to different power**, automobile engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrids. 2. Others:

Common gasoline engines and diesel engines are reciprocating piston internal combustion engines, which can convert the chemical energy of the fuel into the mechanical energy of the piston movement and output power to the outside world. The gasoline engine has high speed, small mass, low noise, easy starting, and low manufacturing cost. The diesel engine has a large compression ratio, high thermal efficiency, and better economic performance and emission performance than the gasoline engine.

Summary. There are three reasons for this, the fuel injection pump drive is disconnected, and the transmission gear, the fuel injection pump shaft is broken, and the Cummins engine suddenly dies and then can't start.

Hello, glad your question, here is still in the query analysis even.

There are three reasons for this, the fuel injection pump drive is disconnected, and the transmission gear, the fuel injection pump shaft is broken, will it be the metering unit broken?

No, it's just the three areas above.

Foton Cummins EFI engine 430 hp.

Uh-huh, yes, no problem.

The car broke down halfway, and the repairman couldn't find the reason that the high pressure didn't get oil, and several repairmen said that most of the metering unit was broken.

We analyze the disconnection of the fuel injection pump drive, as well as the transmission gear, which is caused by the broken shaft of the fuel injection pump.

We don't know what the metering unit is for, and whether it will cause a sudden fire if it breaks.

No, trust me and he has nothing to do with it.

Summary. Hello dear! <>

Cummins engines are cold and the car does not catch fire, and some of the reasons are circuit or electronic failures. The phenomenon that occurs is very sudden and without warning. The faults of the circuit are:

The fuse is blown out, the high-voltage coil is broken, the low-voltage circuit is broken, the center ignition wire is off, the distributor head is leaking, and the spark plug is damaged. Electronic failure mainly refers to the loss of function of the computer control board.
