The name and structural characteristics of the fixed support of the automobile engine on the vehicle

Fusele group, composition: cylinder head, cylinder block and crankcase Function: As the assembly base of various mechanisms and systems of the engine, it is the support and fixed crank connecting rod mechanism and other equipment The skeleton and the relevant parts of the tractor chassis make up the frame of the tractor.

Engine front-wheel drive (FF) Engine front-wheel drive is a popular layout form in cars. It has the characteristics of compact structure, reducing the quality of the car, reducing the height of the body floor, improving the stability of control when driving at high speed, and high power transmission efficiency.

It can be rotated in the bearing to form a crank connecting rod mechanism. The top of the cylinder is closed with the cylinder head. The cylinder head is equipped with an intake valve and an exhaust valve.Through the opening and closing of the inlet and exhaust valves, it realizes inflation into the cylinder and exhausting into the cylinder. The opening and closing of the intake and exhaust valves are driven by the camshaft. The camshaft is driven by the crankshaft through a toothed belt or gear.

Engine is a complex machine composed of many mechanisms and systems. There are many structural forms of modern automobile engines. Even if it is the same type of engine, its specific structure is very different.

Car engines are mainly composed of 1 fuel supply system, including fuel tank, filter, oil pump carburetor, or electric injection, etc. 2 The lubrication system includes oil bottom and oil filter. Oil pump, oil pressure gauge, oil pipeline, etc. 3 Cooling system water tank, fan circulation pump, etc. 4 Crank connecting rod mechanism, including cylinder piston crankshaft connecting rod, etc.

What is a fixed engine? It's better to have a full solution! Thank you

1. The foot glue is aging or loose: the foot glue is the glue block between the engine and the frame. Its function is to reduce the vibration and buffering of the engine when it is working, and to fix the engine. Once these machine foot glues are aged or loose, the vibration of the engine will become very intense, and the effect will be much weaker after replacing the machine foot glue again.

2. Fuselage group, composition: cylinder head, cylinder block and crankcase Function: As the assembly base of the engine mechanisms and systems, it is the skeleton that supports and fixes the crank connecting rod mechanism and other devices, and the relevant parts of the tractor chassis form the frame of the tractor.

3. Abnormal noise caused by aging or loosening of the machine foot pad. The foot mat, also known as the chicken claw mat and the foot mat, is generally installed between the engine and the car body, connecting the car body and the engine, and playing a role in fixing the engine. And its most important role is to have the effect of cushioning and absorbing shock.

Is the motorcycle engine firmly fixed on the frame by a few screws

1. Big jitter. The reasons are as follows: Most of the shaking of the Tiger Shark is caused by the unstable fixing screws of the engine and the frame.The engine and frame of the Haojue Tiger Shark are fixed with ten screws. If these screws are loose or not tightened correctly, it will cause a large vibration of the engine during operation, causing the shaking of the whole vehicle.

2. If it's just a screw on the shell, it's generally about 30. Basically, 8 and 10 socket wrenches are fine. There are also screws of other specifications, but they are relatively few. In the past, some used Phillips screwdrivers, but now there are basically none.

3. Jialing 70 motorcycle, there are two fixing screws between the engine and the frame, one on the back of the engine and the other behind the engine. You need to remove the sprocket cover on the left side of the engine to see it.

4. There are generally four large bolts and springs to fix the engine shock absorber bracket. The engine is usually fixed by two long bolts and nuts to fix the engine on the bracket.Or other ways of four-point fixation. At least two longitudinally fixed with the engine on the exhaust pipe, a total of 3 to 4 screw sets can be completed.

5. The horizontal engine should be replaced with a horizontal 125 engine. If it is a model of the same series, basically the screw hole of the engine can be fixed on the frame, but it is not absolute, because 110 and 125 have many models of engines, even if they are of the same series and different manufacturers. Or there may be differences in different periods.

6. It is abnormal. There should be no gap between the engine of the motorcycle and the frame, otherwise there will be obvious vibration during driving, which may even affect the normal driving.

Chang'an cross-diesel vehicleIs the engine fixed?

1. The rated speed of the high-speed diesel engine is more than 1500 rpm. The engine of Chang'an Crossing King x5 diesel version is 1800 rp, so it is a high-speed engine.

2. The quality of Chang'an Crossing King diesel car is good. Chang'an Crossing King is a pickup truck under Chang'an, which adopts a 2L engine to meet the needs of pulling people and carrying goods.

3. The Guoliu Liuji 8L engine used by Chang'an Crossing King PLUSE, the Guowu Mingyou gasoline engine used in the old model, and the Chang'an Crossing King X5Plus small and light truck have also made a series of adjustments in terms of power system, and launched a variety of different power versions, compared with the 5L engine , the power improvement is more obvious.
