Chery qq The 372 and 472 engines are better

1. The engine is very stable and the steering is easy to use. And it is very fuel-efficient. It is an economical and practical car for home use.

2. Chery Q3 has two displacements, but it is equipped with SQRE3G0SQR371F and CAC-SQR472 independently developed by Chery. SQRE3G08 and SQR371F adopt a three-cylinder and four-door structure, matched with a 5-speed manual transmission. CAC-SQR472 is a four-cylinder four-gale engine with low manufacturing cost and can improve the intake efficiency of the engine.

3. Hello, the Chery QQ currently on sale is equipped with three engines, which are configured in different models. If my answer is helpful to you, please set it as the best answer.

4. Different engines Chery qq3: Adopts CAC472 four-cylinder 16-valve double-top camshaft engine, which has better smooth operation, and more sufficient single-cylinder 4-valve intake and exhaust. QQ308: All the engines have been replaced with the 372 engine jointly designed and developed by Chery and a world-renowned engine design company.

5. The engine of the Chery QQ372 car is equipped with a continuously variable valve timing system (CVVT), which continuously changes the system of opening and closing the intake valve according to the phased changes of engine speed and vehicle load. 06 Model QThe 1L displacement series in Q is fully equipped with Chery's own new CAC472 engine this time.

What will be the impact of the two teeth of the camshaft of the 472 engine are misaligned

1. The wrong tooth should affect the overall performance of the vehicle.It is an indirect control of the ignition sequence of the vehicle, that is, the ignition advance angle, the control of the camshaft indirectly controls the opening of the inlet and exhaust valve and the closure of the water pump, and provides data to the driving computer, that is, the ignition time control.

2. There are many deformations of the shaft. I don't know which one you are talking about. In terms of bending deformation, it has a great impact on gear meshing, which will cause the meshing line to shift to the large diameter of the wheel teeth, thus reducing the bending strength of the gear root and the life of the gear.

3. If the timing belt installation error of the car is slight and the deviation is small, the car will be weak and unable to add oil uphill. If it is more serious, there is no idling, or the engine trembles seriously in the idling state, and the exhaust pipe bursts when refueling.

4. Camshaft orthoticing method, the orthotical timing of this engineThe point is that the four pistons are in a horizontal position after the positive sign. There are two marks on the forward camshaft that move on the same parallel line, and there are also two marks on the middle cylinder.

5. Pressure, burst, discharge, and there must be no error in the cooperation, otherwise the valve will either open or close early, causing great damage to the engine. The gas distribution mechanism is an advance angle, which is used to make the turnover of the crankshaft and the camshaft through the belt teeth. If the teeth are not right, it is easy to cause the valve bar to bend.

advantages and disadvantages of byd472qa engine

reduces power density, low efficiency and low torque at low speed. The 5L engine can only output 135Nm peak torque at 4500 rpm, which is not suitable for pure fuel vehicles.There is some noise.

BYD 472qa engine adopts advanced combustion technology and optimized design to make it have the characteristics of high efficiency. The engine excels in fuel efficiency, which can effectively improve the fuel economy of the vehicle.

BYD472QAD's engine is of good quality. It is a four-cylinder naturally aspirated engine, and its power is widely recognized by consumers. BYD472QAD has low power density, poor efficiency and low torque at low speed.

byd472qa is very good. This model of engine has the first place in terms of performance and quality, high power, low fuel consumption, good quality of steel, excellent price and reputation, good accessories for luxury cars, everyone says it's good.

Not great. As long as the car shakes when driving, bigThe family will say that the engine is shaking, and subconsciously feel that the problem is very serious. In fact, shaking is inevitable when the engine is working, but under normal circumstances, the shaking of the car engine should be very smooth and regular.

BYD engine is energy-saving and environmentally friendly. BYD engine adopts European V standard, which is installed on cars to ensure effective emissions and meet the requirements of national environmental protection standards. In addition, the engine adopted by the European V standard can reduce the fuel consumption of the car and achieve energy saving and emission reduction.

How about the engine of Chery 472

The engine is good. According to the relevant public information of the query, the number of cylinders of the engine is different. 472 is a 4-cylinder engine timing belt drive, which saves time.Save effort. 371 is a 3-cylinder engine with timing chain drive, and the chain drive will be easy to fail, so Chery qq372 and 472 engines, 472 engines are good.

sqr472wd engine is good. The advantages of sqr472wd engine are: high reliability: sqr472wd engine adopts advanced technology and simple structure, which reduces the possibility of failure. High efficiency: The engine adopts SOHC and VVT intelligent valve timing technology, which improves combustion efficiency and reduces energy loss.

Chery 472 is good. There are two models of Chery QQ engines. The early one used the Dong'an 465 engine, which was eliminated early. At present, the 472 engine independently produced by Chery is used. Reliable quality and power, and convenient maintenance.

The engine of the Chery QQ372 car is equipped with a continuous variable valve timing system (CVVT), which continuously changes the intake valve opening and closing system according to the phased changes of engine speed and vehicle load. The 1L displacement series in the 06 QQ is fully replaced with Chery's own new CAC472 engine.
