What kind of engine is Huapu?

"Next, I'll do it.Explanation for everyone: Huapu Haishang's engine model MR479QA displacement (mL) 1498 intake form naturally aspirated: Haishang (sedan) is equipped with a strong JL481Q, 8L engine, which is powerful, and the car is easy to move freely.

The 3L model of Huapu Sea uses Geely's 3L in-line four-cylinder 16-bale engine, which is basically the same as the engine on the Liberty ship: Huapu belongs to Geely, which is relatively backward in technology and has a high repair rate.

The Huapu Haixun engine is not a joint venture, but a 5-displacement independently designed and developed by Geely. The technological progress of this engine is completely based on Toyota's 8a engine.

Where is the engine number of Huapu Automobile?

1. Where is the engine number of Huapu Automobile? The engine number of Huapu Automobile is on the cylinder block of the engine, close to the gearbox. The engine number can also be found on the vehicle license plate. The engine number is a mark to prevent arbitrary modification of the engine, which must be checked during the annual vehicle inspection.

2. The engine number can be seen on the driving license, under the windshield, and on the right plate of the engine throttle valve.

3. To sum up, the engine number is usually located under the engine cover of the car, in the engine room or on the vehicle registration certificate. Through careful observation and search, you should be able to find it. Here, we attach an diagram to help you better understand the location of the engine number.

4. On the left side of the engine, under the third-cylinder spark plug in the middle.On the nameplate in the engine room. On the motor vehicle driving license, the VIN code is printed in the "Vehicle Identification Code" column. Composition of engine number: head: including product code, replacement symbol and enterprise code, which can be used to identify.

5. Your good friend. On the cylinder block. Close to the gearbox. I hope I can help you [If there is a problem with the car, ask the car master. 4S store professional technician, 10 minutes to solve.

What is the reason for the sound of the old engine guard of Huapu?

One is that the guard plate frictions with the moving parts outside the engine, causing abnormal noise, and the other is that the guard plate is close to the vibration frequency of the car, resulting in resonance; it is difficult for ordinary car owners to distinguish which are faulty abnormal sound and which are reasonable abnormal noise. When I went to the repair shop to test the abnormal sound of the vehicles, only nearly 20% of the vehicles really had problems.

If the noise is loud after installation, it may be caused by the resonance of the protective plate and the engine during driving. Common engine protection plates are made of resin, steel and alloy steel. The resin engine guard is made of general-purpose resin, and some manufacturers who keep up with the times adopt a fully closed design.

It is possible that the quality of the engine guard is not good or the installation is wrong. It is best to remove it, rinse the inside of the guard, and apply a layer of shock absorber, which is very effective. The engine guard is an engine protective device designed according to various different models. Its design is first of all to prevent damage to the engine caused by impact.

However, the biggest disadvantage of the metal guard plate is resonance and noise. If the chassis is really scraped, it is likely to cause deformation of the metal guard plate. If this is a necessary part, it will be installed in the original factory.

If there is a "squeak" sound when stepping on the brake, it is probably caused by excessive wear of the brake pads, resulting in unnecessary gaps. Of course, improper use or deformation of the brake disc material, unqualified hardness, porosity, friction characteristics and compression characteristics of the brake disc may lead to abnormal noise.

There is a steel guard under the engine, which may have been rubbed by an obstacle.

Why is there an engine failure light on after a long-distance stop in 12 years?

The fuel quality of the car is not qualified. If the engine fault light on the dashboard of the car lights up shortly after the vehicle is refueled, then it is generally due to the wrong oil addition, poor quality, and non-standard, resulting in insufficient combustion of oil-gas mixture when the engine is working.

Fault phenomenon: If the engine speed is unstable, the power is obviously insufficient, and there is a tempering phenomenon, it can be considered that the engine has a fault of excessive mixed gas.

The third reason is the serious carbon accumulation in the cylinder, which usually exists in cars that often drive at low speed in urban areas.Once this is serious, it may also cause engine explosion, and then the car will have a decrease in power, abnormal jitter to produce noise, and even knock on the cylinder. At this time, the fault light will definitely issue a warning.

Bad combustion will occur, and the engine fault light will turn on. The failure of the vehicle engine emission system is the most important and one of the most common reasons for the vehicle engine failure light. If this kind of failure occurs, most of it is the cause of carbon accumulation in the vehicle engine or the problem of fuel quality.

The specific analysis is as follows; sensor problem; the sensors mentioned here include water temperature, crankshaft position, air flow, intake temperature, oxygen sensor, etc. When these sensors are damaged, poor contact or the signal is interrupted, the ECU of the car cannot accurately obtain the engine data, and at this time it will Cause the engine fault light to turn on.
