How to check the quality of the engine?

The following is the way to judge whether the engine is good or bad.Method: It depends on the engine speed. Generally speaking, the engine speed between 2500 and 3000 is more suitable for the engine speed. In the same case of 120 miles, the more expensive the car, the lower its engine speed may be.

Judge whether the engine combustion is normal by the condition of the exhaust pipe. If there is dripping water at the exhaust port of the vehicle, it does not mean that our engine is broken, but that our engine burns well. If there is black smoke or blue smoke from the exhaust pipe, there may be a problem with the engine.

Check the appearance of the engine and identify the traces of oil leakage and water leakage. Check the external cleanliness of the engine to see if there is too much dust to determine whether the wear is too much, but pay special attention to the fact that if it is spotless, it does not mean that the car is worn very little, or it may be that the owner has done something to cover up some information.

The distribution of judging whether the engine is good or bad is as follows: The engine form determines the grade. In general, according to the displacement size, the engines are divided into three-cylinder, four-cylinder, six-cylinder, eight-cylinder and turbocharged types, while L4 (in-line four-cylinder engine) and V6 (V-type six-cylinder engine) and turbocharged Pressure models are more common.

What do you think about the quality of the car engine

The following is the way to judge the quality of the engine: look at the engine speed. Generally speaking, the engine speed between 2500 and 3000 is a more suitable engine speed. In the same case of 120 miles, the more expensive the car, the lower its engine speed may be.

Looking at the good or bad performance of the car, it mainly depends on the exhaust pipe.The main function of the exhaust pipe of a car is that the waste can be discharged after the engine burns. The quality of the discharged gas can be fully seen from the condition of the engine when it burns.

Judge whether the engine combustion is normal by the condition of the exhaust pipe. If there is dripping water at the exhaust port of the vehicle, it does not mean that our engine is broken, but that our engine burns well. If there is black smoke or blue smoke from the exhaust pipe, there may be a problem with the engine.

The quality of the engine can be roughly distinguished from the three points of power, fuel injection form and manufacturing process. As we all know, the engine is the heart of the car. Only the heart of the car can see that there are some problems with the engine, so you can judge the quality of the engine.

First of all, it is the most intuitive method and the simplest method of judgment.Just look at the exhaust pipe at the rear of our car and see if there will be water droplets in the position of the exhaust pipe. This is a very simple way to judge whether an engine is good or bad.

The quality of the engine mainly depends on these aspects?

1. The following is the way to judge whether the engine is good or bad.: It depends on the engine speed. Generally speaking, the engine speed between 2500 and 3000 is a more suitable engine speed. In the same case of 120 miles, the more expensive the car, the lower its engine speed may be.

2. Judge whether the engine burns normally through the exhaust pipe. If the exhaust outlet of the vehicle drips, it does not mean that our engine is broken, which reflects that our engine is burning well. If there is black smoke or blue smoke from the exhaust pipe, there may be something wrong with the engine.

3. So for a car, which aspect of the configuration can determine its quality? In fact, for a car, I think the most important accessory in it is the engine.

What about the car engineWhether it's good or bad

First of all, when the engine starts, you should observe whether the start-up process is smooth. It is directly started successfully within 2 seconds after ignition, and then runs smoothly, indicating that the engine has good starting performance. Secondly, after the engine is started, observe the stability of the engine operation.

There are several ways to judge whether a car engine is good or bad: After starting the engine, listen to the sound of the engine (idling, medium speed, high speed) in three working conditions. Fuel consumption: The number of kilometers you run determines the fuel consumption, and the quality of the engine can be judged by the fuel consumption. Check the tightness of the cylinder.

Judge the quality of the car engine, check the appearance of the engine, and identify the traces of oil leakage and water leakage. Light the engine and observe the color of the discharged gas. If it is translucent light gray, sayObviously, the engine is in good condition. If the gas discharged is black, it means that the engine has not been adjusted well.

On the contrary, if the engine exhaust pipe does not drip, it means that the fuel combustion of the car is insufficient, or the sealing problem of the engine is not good. Of course, it depends on the quality of an engine and whether the exhaust pipe drips, which is just a simple auxiliary method. I can only give you a general judgment.

Judge the quality of the engine by the power of the engine. For example, if the engine is weak in refueling, it is very likely to be due to excessive carbon accumulation in the combustion chamber of the engine, or the leakage of air intake system, blockage of the fuel injection nozzle, etc. Look at the appearance of the engine to see if there are water leakage, oil leakage and other phenomena.

Look closely at the hood. When opening the hood, first check whether the inside has been painted or not. If so, it means that the cover has been hit. Look at the two longitudinal beams or the two inner sub-beams under the body. Under normal circumstances, there are round spot welding marks in these places. If the shape and size of the spot welding are different, it may collide.
