• Are the hood and the hood the same thing?
• 5, The reason why the hood of the car heats up

What material is the engine shell made of?

Car engines are generally made of cast iron and aluminum alloy, and now there are also aluminum-magnesium alloys.The housing of aerospace engines is generally made of ultra-high-strength steel.

The engine shell is cast from aluminum alloy. Crankshafts, valves, cylinders and gearboxes are generally machined with high-carbon steel. The cylinder and piston ring need to be electroplated with rare metal chromium.

The materials of the Suteng engine shell are: metal material, steel plate, carbon fiber, aluminum, reinforced plastic, etc. The materials of different car shells and different parts are different, generally steel plate, high-end cars are aluminum, racing cars are carbon fiber, and some car hoods are reinforced plastic.

The basic structure of the engine?

Engine valve chamber cover, the engine valve chamber cover is abbreviated as valve chamber cover. It is the sealing component of the top part of the engine, and the oil supper.Correspondingly, the engine lubricant is sealed, so that when the engine is running, the lubricating oil will not leak out. The function of the cylinder head is to seal the cylinder, form a combustion space with the piston, and withstand the effect of high-temperature and high-pressure gas.

The engine is composed of two major mechanisms and five major systems: crank connecting rod mechanism, gas distribution mechanism, fuel supply system, lubrication system, cooling system, ignition system and starting system. The crank connecting rod mechanism is the main moving part of the engine to realize the working cycle and complete the energy conversion. It is composed of a fusele group, a piston connecting rod group and a crankshaft flywheel group.

Most of the gas distribution mechanisms adopt the overhead valve gas distribution mechanism, which is generally composed of valve group, valve transmission group and valve drive group.

The basic structure of the engine is roughly composed of two major mechanisms and five major systems.Composition, that is, crank connecting rod mechanism (including fuselage) and gas distribution mechanism, fuel supply system, cooling system, lubrication system, start-up system and ignition system (for gasoline engines).

Hello, the engine is composed of two major mechanisms: crank connecting rod mechanism and gas distribution mechanism, as well as cooling, lubrication, ignition and fuel supply. It is composed of five major systems such as the start-up system. The main accessories are. Cylinder block, cylinder head, piston, piston pin, connecting rod, crankshaft, flywheel, etc.

The reason why the engine bottom shell is made into an irregular shape

Because of the organic oil collector filter in the oil pan shell. In addition, the car body tilts when going uphill, downhill and passing through uneven road surfaces. In order to facilitate the oil pump to better provide oil and ensure good lubrication, it must be made into a half-light and half-deep shape. When you disassemble the engine and see its internal structure, you will naturally understand it.

Increasing the heat dissipation area is not made irregularly, but according to the shape determined by the structure inside the engine oil span. There is an oil pump inside. Of course, the shape of the oil sall should also be determined according to the external structure of the engine.

The oil pan is used to store oil and close the crankcase.In order to ensure that the oil pump can absorb oil normally when the car tilts, the oil pan shell is usually made deep. That is, there is a gradient, not a rectangular square box.

The surface of different engine pistons has different shapes. The ultimate goal is to make the mixed gas more fully mixed and the internal convection of the engine stronger. Generally, the piston of a diesel engine is flat, with a depression in the middle, and a bulge in the middle of the depression. Diesel is sprayed here for mixed combustion. The surface of the direct injection engine is convex.

These two things are related to a part called "exhaust valve" (EGR). Exhaust gas valve (EGR) is also known as "oil-gas separator". Because the piston of the engine has an irregular shape, the piston moves up and down, and the crankshaft moves around the circle. In order to protect the cylinder block, the piston is designed into an irregular shape.

If the car is lifted by a lift, the old oil flows out naturally by gravity. Due to the oil outlet angle and the irregular structure of the oil span, there is always a part of the oil that cannot flow out naturally. Because the engine oil has been used for a long time, there are many impurities, which cannot be completely cleaned.

Are the hood and the hood the same thing?

1. The hood is the engine cover, which is made of rubber foam and aluminum foil. When reducing engine noise, it can simultaneously isolate the heat generated by the operation of the engine, effectively protecting the paint on the surface of the hood and preventing aging. The function of the hood: air diversion.

2. The structure of functions is different.The hood is the cover of the front of the entire vehicle. Its function is to protect the engine and other mechanical parts, while providing heat insulation and sound insulation. The hood is a component under the hood, which is to cover and protect the engine and prevent dust, water vapor, etc. from entering the engine.

3. The hood, also known as the hood, is a part designed in automobile design for convenient maintenance. Usually, we need to add glass water, engine oil, brake fluid and steering auxiliary oil under the hood. Especially when adding antifreeze, it is usually necessary to open the engine hood.

4. The hood is actually the engine cover. The engine hood refers to the engine cover, which can play a disturbing role to a certain extent, and at the same time, it can also play a role in beautifying the engine compartment.

5. How to open the front hood of the car? The hood of the car is the most eye-catching body component of the car engine cover (also known as the engine hood) and one of the parts that car buyers often need to check. The structure of the engine cover is generally composed of engine cover heat insulation/sound insulation cotton, engine cover snap, engine cover support rod and other parts.

6. The advanced engine hood has a layer of soundproof sponge on the inner wall of the engine compartment, and there is an adhesive strip at the opening, which can effectively reduce the engine noise; the engine guard is on the top of the engine. In order to prevent water, oil and other precision originals such as water and oil from contaminating spark plugs and solenoid valves, the engine hood is under the hood, playing a role More layers of protection.

The reason why the hood of the car heats up

The engine hood heats up is a normal phenomenon.Because the heat emitted by the engine will accumulate on the hood, you can also look at the water temperature gauge at this time. If the water temperature is about 90 degrees, it is normal.

The operating temperature of the engine itself is very high. If the front hood is very hot after the vehicle runs for a period of time, but the dashboard shows that the water temperature is normal, this situation should be normal.

The reasons for the heating of the car hood are as follows: the first step is to check whether there is an alarm of excessive water temperature in the indoor dashboard alarm. If there is an alarm of excessive water temperature, it must be caused by excessive water temperature.

The continuous heating of the hood is not a bad thing: first of all, relying on the car's own heat dissipation system in summer, the heat of the engine will not cause damage to the car body; secondly, in winter, the residual temperature of the engine is conducive to the success of the next ignition.Therefore, there is no need to be overly nervous about the problem that the hood is still very hot after the car is turned off. It is just a normal phenomenon of the car.

Because the working temperature of the engine is generally 90 degrees, the heat of the engine is transferred to the hood, and the hood will heat up. If there is no heat-insulating and noise-reducing cotton on the inside of the hood, the heat will be more obvious.

The hood will heat up. If there is no heat-insulating and noise-reducing cotton on the inside of the hood, the heat will be more obvious. The heat of the engine movement is emitted to the cabin cover, including the heat of the radiator. As long as the water temperature gauge on the dashboard does not show that the water temperature is too high, there is no problem. Secondly, confirm whether the radiator fan is working normally.
