How about the quality of the Lifan 620 engine

Durability. An engine is a machine that can convert other forms of energy into mechanical energy. The Lifan 620 adopts the 6LTritec engine imported from Brazil, and the Lifan 620 engine is durable. It has ultra-high power and fuel economy.

The stability performance is also relatively strong. The 12-year-old Lifan 620 automatic transmission is a transmission device that automatically changes gears according to the speed and engine speed, so the 12-year-old Lifan 620 automatic transmission is very good.

Durable. It can be said that the engine is fuel-efficient, durable and powerful! Lifan 620 is equipped with an electronic anti-theft system, automatic door and window closing system, main and auxiliary airbags, leather seats, audio-visual system, electronic central door lock, MP3USB interface, automatic air conditioning, etc.

The score is only 3 stars. In summary, as an independent brand car, Lifan 620 performs well in terms of appearance, interior and power, but there is still a lot of room for improvement in terms of safety performance. When buying a second-hand car, it is recommended to buy it through regular channels and do a good job of sufficient testing to ensure the quality and safety performance of the vehicle.

Hello, the overall performance of the Lifan 320 is still good. The vehicle engine is relatively solid, and the durability and fuel consumption are relatively low, and the cost performance is relatively high @2019.

Lifan 620 engine model LF479Q2 displacement 149815L naturally aspirated maximum power 69KW 94 horsepower maximum torque 128 Nm national No. 4 93 oil 8A displacement 13L, maximum power Kwrpm 636000, maximum Torque Nmrpm 1105200, compression ratio 93.

Why does Lifan 620 emit white smoke

The reason why the car exhaust pipe drips is that gasoline turns into water vapor and carbon dioxide after complete combustion. Water vapor is colorless and transparent at high temperatures, but when the temperature is below 100 degrees, the water vapor will condense into water. If the condensed water droplets are small and suspended in the air, the water vapor is a white gas.

The white smoke from the exhaust pipe is water vapor; the condensed water vapor gathers into water droplets and will be discharged by itself with the exhaust pipe. Water and carbon dioxide are produced after the complete combustion of gasoline, and water is gaseous at high temperatures. But when water vapor enters the colder air, it condenses into water.

It's good to change the air conditioner filter at the beginning to survive last summer. This year, there have been several major situations, that is, not long after the hot wind blew the air conditioner, the abnormal position of the car engine made a serious noise, the car shook, and then smoked. I was scared to pee. There was no problem when I opened a car repair shop, and others couldn't solve it. It appeared again this winter, and I just came across this situation when I drove there.

Hello, if the water tank cover is broken, after the engine water temperature is too high, it will spray out of the cover, causing water shortage and excessive temperature.Please replace the water tank lid in time.

How about the quality of Lifan 620 second-hand cars?

1. In summary, as an independent brand car, Lifan 620 performs well in terms of appearance, interior and power, but there is still a lot of room for improvement in terms of safety performance. When buying a second-hand car, it is recommended to buy it through regular channels and do a good job of sufficient testing to ensure the quality and safety performance of the vehicle.

2. If there is no problem with the procedures, the second-hand car of Lifan 620 can be purchased: Lifan 620 is the main model of Lifan Automobile in the second half of 2008. After a comprehensive and strict listing evaluation before the market, it has a better quality improvement compared with previous models in terms of quality and performance. Rise.

3. If the second-hand Lifan 620 is in good condition, even if the price is slightly higher, it will attract the attention of many buyers. As for the quality of the vehicle, it mainly depends on the owner's usual use and maintenance. If the owner of the car often maintains it and has a complete maintenance record, it is also guaranteed to buy such a second-hand car.

4. Secondly, Lifan's quality control is difficult to describe. Poor quality and high fuel consumption is everyone's general impression of Lifan. Take Lifan 620 as an example, engine valve chamber cover oil leakage, gearbox oil leakage, sunroof leakage, interior noise and other problems are easy to occur, and the quality of the vehicle is indeed poor.

5. OK. According to the official website of the owner's guide: In terms of materials: Lifan 620 engine adopts polymer polymer lightweight materials, which has good thermal insulation effect and good quality.Durability: The Lifan 620 engine is equipped with the 6LTritec engine imported from Brazil, which is highly durable.

6. The Lifan 620 is cheap, the space is large, the materials are average, and the workmanship is poor. Compared with the old model, the appearance of the Lifan 620 is quite fashionable when the inverted trapezoidal air intake grille is well connected to the headlights. The shape of the body and the rear of the car is designed in a moderate way, without much characteristics. Compared with its competitors, it still has a big gap.

Lifan 620 is turned off and the throttle can't be added

1. The combustion is not good and the ignition energy is low: the spark plug gap is too large, the ignition coil is aging, the high-voltage line of the spark plug is aging or the power leakage in a closed loop In the controlled car, oxygen transmissionThe minimum working temperature of the sensor is 370 degrees Celsius. If you just start the car, the oxygen sensor will not work because the temperature in the exhaust pipe does not reach 370 degrees Celsius.

2. Another reason is that the throttle valve is faulty. The above two problems will cause engine shaking and unstable speed.

3. Mine is also Lifan 620. It is a 2009 model. The following is the problem of the car. When the antifreeze leaks at the water tank interface for more than 1,000 kilometers, it has been dealt with for a total of 4S8 times. At more than 10,000 kilometers, the two shock absorbers in the front were replaced with abnormal sound, and all the four glass lifters were replaced (abnormal sound). Now there is still abnormal sound after the warranty, and the right transmission shaft has been replaced.

4. This may be due to low-voltage power failure and engine failure during driving. At this time, you can mainly check the switch of the ignition and starter, as well as the fuse box.The short circuit of the low-voltage line causes the engine to be turned off, in which case it is intermittently turned off. Check your low-voltage line. One is a device failure.

5. It is possible that the fuel injector has glue attached to it. The fuel injection of the cold car is not smooth, and the hot car has no problem. It is recommended to try a few high-speed runs. If it still doesn't work, we need to clean the fuel injector.

6. It is estimated that there are several possibilities: the spark plug does not work, because the spark plug cannot provide a strong enough temperature, causing the engine to be weak and the engine to turn off. If the clutch is not completely separated, the car will also perform as if it is not smooth to step on the clutch. The idling control valve is dirty, so that the engine cannot return to the idle state.
