The throttle problem of Isuzu cars, what is the lack of engine power of Isuzu cars?

I think if the oil circuit and pump are fine, it must be one less cylinder to work. That is to say, if you want to do it, the grease nozzle is stuck and does not atomize. If it's a problem in the tank, you can find a repairman to check this aspect.

There is also the case of a clogged exhaust pipe (of course, this is rare...). It only takes the repairman to disassemble the exhaust branch pipe and try it... Of course, this is just my personal opinion, if you want to really fix it, you have to treat it like a doctor, and everything is clear, and then you can take the right medicine.

Find a professional school oil pump to calibrate the oil pump nozzle and then check the oil circuit and wash the oil tank, if it doesn't work, then check the engine to see if there is a cylinder that works badly.

Calibrate the oil pump nozzles, and then clean the oil circuit, if it doesn't work, then check the engine to see if any cylinder is working badly.

It may be that the air intake first checks whether the oil circuit is blocked, especially the pipe and hollow screws from the hand oil pump to the fuel tank The diesel filter element should also be replaced, and sometimes the oil will not be added, and then it will not be possible to change the oil pipe.

With a barrel of diesel. Use the oil pipe to go straight to the oil pump, test run, if there is no problem, it is the problem of the oil circuit and the oil tank, otherwise, it must be the problem of the oil pump, the oil pump is not well calibrated, to the professional school.

1. The sensor is damaged, the contact with the carrying object is bad, or the signal is interrupted; 2. Poor engine maintenance; 3. The quality of fuel and oil is not good; 4. The combustion of the mixture is insufficient; 5. a spark plug.

malfunction, ignition coil failure; 6. The fuel pump is faulty and the oil circuit is blocked; 7. The air conditioner filter is blocked.

1. Sensor problems; The sensors mentioned here include water temperature and crankshaft.

Position, air flow, intake air temperature, oxygen sensors, etc., when these sensors are damaged, poor contact or signal interruption, the ECU of the car cannot accurately obtain engine data, and the engine failure light will be on. 2. Maintenance problems; Poor engine maintenance is the most common cause of engine failure to light up. We know that the vehicle has a certain maintenance cycle, if the owner does not maintain on time, coupled with bad driving habits, then it will increase the burden of engine operation, and finally can only remind you through the fault light to care about your car 3, oil quality problems; The oil quality here includes fuel and engine oil, we know that the fuel filled by the car is generally marked, and the engine oil is also semi-synthetic and fully synthetic, the manufacturer will generally recommend the owner to use which grade of fuel, what type of engine oil, if the owner does not add as required, it will cause wear and tear of the engine in the long run, and the fault light is not to blame.

Poor combustion of the mixture; The failure of the spark plug, ignition coil, fuel pump, and oil circuit blockage of the engine will cause poor combustion of the engine mixture. Poor combustion of the mixture is caused by the problem of engine carbon deposition or knocking, and these will eventually be detected by the engine's oxygen sensor and reported to the ECU, which will naturally turn on the fault light to warn of the intake air intake problem; When the engine burns, it needs to take in the air, and in the process the air cleaner is required.

It is very important, if the air filter of the car is not clean, it will affect the air intake of the car if it is not cleaned regularly, and it will be blocked in the long run, and in serious cases, it will cause the engine failure light to turn on. pressurization issues; Intake booster lines, turbochargers.

It will also cause the engine failure light to illuminate. The most common of these is turbocharger damage, while the vehicle can also experience symptoms such as oil leakage, high oil consumption, loss of power, metal noise, and blue or black smoke from the exhaust pipe. 7. Exhaust problems; Rear oxygen sensor, three-way catalytic converter.

Exhaust camshafts and bearings.

The most common of these is a failure of the three-way catalytic converter that causes the engine failure light to illuminate. The use of leaded gasoline, the use of leaded or silicone lubricant additives, the bump of the three-way catalytic converter, and the failure of the engine oil supply system are some of the factors that can easily cause the failure of the three-way catalytic converter. anti-theft system; If the car's electronic immobilizer fails, or if the immobilizer does not match the engine electronic controller, the immobilizer system will also cause the engine to not work properly and the engine fault light will be lit at the same time.

Summary. Hello. Friend.

1. Gearbox failure. If it's a gearbox, it's easier to judge. If there is a problem with the gearbox, the throttle cannot be pressed, and the engine speed will suddenly increase by 2000 to 4000 rpm.

Because the power is cut off, the engine suddenly goes to zero load, and its speed will fluctuate. There are general problems with the engine, including problems with the transmission control system, the engine light will be on, and the fault light must have stored the fault, so we use the diagnostic instrument to read the fault.

2. Throttle.

3. Gas pedal.

4. Brake priority system. Like the current car, it is also equipped with a brake priority system, that is, the brake pedal and the accelerator pedal are pressed at the same time, the brake pedal is prioritized, and the accelerator does not respond. If the pad accidentally touches the brake pedal, it is possible that if it touches the brake pedal a little, there will be a brake signal, then it is possible that the brake priority system is working.

Check it out, friend.

Hope it helps.

Isuzu trucks can't step on the accelerator and can't raise speed.

I hope you can give me a thumbs up, your thumbs up are important to me, thank you.

Compared with the same level models, the comprehensive fuel consumption of Qingling, Isuzu Giga giant coffee heavy trucks is more than 4L, some card friends say that they save 10%, and some card friends say that they can save 70,000 yuan by running 200,000 kilometers a year.

However, fuel-saving is not simple, how does this fuel-efficient "giant" do it?

Isuzu engine, fuel economy +1

It is equipped with Isuzu 6U and 6W engines, which are known for their fuel efficiency, with a horsepower range of 350-520PS, a displacement of 10-16L, large low-speed torque, ultra-wide torque band, and a large economic speed area, so as to realize the actual effect of speeding up, fuel-saving and efficient operation of the car.

AMT automatic transmission, fuel economy +2

The AMT automatic transmission transmission in the field of commercial vehicles has high transmission efficiency and avoids the idling fuel consumption caused by frequent clutching, and the data shows that the average oil bending consumption of vehicles using AMT transmission is 3%-5% lower than that of manual transmission

Hydraulic retarder, fuel saving +3

Equipped with hydraulic retarder, the vehicle runs smoothly and achieves the effect of fuel saving, at the same time, there is no need for a water sprinkler, saving the cost of adding water, and the maintenance cost of the braking system will be saved every year, and the most important thing is that the driving safety is further guaranteed.

Four-airbag suspension + rear lift axle, fuel economy +4

The airbag suspension ensures driving comfort and cargo safety, and the rear lifting axle can be used to lift the axle when the vehicle is empty, reducing the friction and wear of tires on the ground, and also helping to reduce fuel consumption.

Summary. Hello. We'll be happy to answer for you.

How to control the throttle of Isuzu 4 h k 1 The answer is: the working principle of the electronic throttle is that the electronic throttle is to control the opening of the throttle through a cable or wiring harness to achieve automatic control function, and the electronic throttle replaces the cable or pull rod with a wire harness or wire, and a micro motor is installed on the throttle side to drive the throttle opening with an electric motor, which is the so-called wire driving, and the original mechanical transmission mechanism is replaced by a wire. Advantages of electronic throttle:

1. The driver's intention can be judged according to the details of the action amplitude of stepping on the accelerator, so as to achieve accurate control; 2. High stability, not easy to stall and break. The electronic throttle control system is mainly composed of the accelerator pedal, pedal displacement sensor, ECU (electronic control unit), data bus, servo motor and throttle actuator.

The engine on the excavator can't add the throttle now, how can you add the throttle.

Hello. We'll be happy to answer for you. Isuzu Zen Spring 4 h k 1 throttle how to control the answer is:

The original principle of the electronic throttle is that the electronic throttle is to control the opening of the throttle through a cable or wiring harness to achieve automatic control function, and the electronic throttle is installed with a wire harness or wire instead of a cable or a rod, and a miniature motor is installed on the throttle side to drive the throttle opening with an electric motor, that is, the so-called wire driving, and the original mechanical transmission mechanism is replaced by a wire. Advantages of electronic throttle: 1. It can judge the driver's intention according to the details of the action amplitude of stepping on the accelerator, so as to achieve accurate control; 2. High stability, not easy to stall and break.

The electronic throttle control system is mainly composed of the accelerator pedal, pedal displacement sensor, ECU (electronic control unit), data bus, servo motor and throttle actuator.

Hello dear! The engine on the excavator can't add the throttle now, how to add the throttle 1, first of all, check whether the electronic control throttle is noisy and whether it fails; 2. Secondly, consider the failure of the engine itself; 3. There is a hidden fault in the electronic control throttle circuit; 4. Problems with the throttle controller will also cause the failure; 5. If there is a problem with the instrument program, although the probability of occurrence is not large, it cannot be eliminated by touching the cherry blossoms. In the process of overhaul and disassembly, the causes of the fault problem can be listed, and then the machine is powered on and started smoothly, and the throttle knob is twisted to see if the instrument gear is displayed normally, and it is found that the normal gear can be displayed, so it can be judged that the throttle knob is no problem.

The reasons why you can't fill up the oil are:

1. Oxygen sensor failure;

2. The quality of gasoline is not up to standard;

3. The air leakage of the inlet pipe leads to the mixture being too thin;

4. The fuel pressure is low, and the fuel injection finder and fuel filter are blocked;

5. The pressure sensor and throttle position sensor detect signal abnormality;

6. The ignition timing is inaccurate and the ignition is too late.

7. Weak high-voltage sparks due to poor spark plugs, igniters or high-voltage wires;

8. The throttle is dirty;

9. The exhaust gas recirculation system works poorly;

10. The exhaust pipe is blocked;

11. The cylinder pressure is low;

12. Zheng Xiangli turbocharging system failure.
