On the question of the under engine guard of the car

It is absolutely necessary to install, preferably steel. Because of the strong steel, it has better protection for the engine and a high safety factor in case of a collision between a bad road condition and a protrusion on the ground. Don't worry about the weight, it's very light. No matter what road conditions you drive, you need to install it, and prevention is the main thing.

It is necessary to load. It is best to be made of titanium alloy, which dissipates heat quickly and does not rust. However, it is a little higher.

The advantage of installing the car engine underguard is to prevent the bottom of the engine from crumbling on the road surface and stones, mainly to protect the oil pan. The disadvantage is to increase the weight of the vehicle, affect the heat dissipation, reduce the road passability of the vehicle, and produce noise if the assembly is not good. If you only drive in the city, you don't need to install it, and if you often have to run in the suburbs or on gravel and bumpy roads, the engine underneath guard can play a protective role

If the guard plate is installed, the screws must be tightened.

Of course it's good to be made of steel.

It depends on the road.

Engine guard is an engine guard designed according to a variety of different models, its design is first to prevent mud from wrapping the engine, resulting in poor engine heat dissipation, and secondly, to prevent damage to the engine caused by the impact of the uneven road surface during driving, through a series of designs to extend the service life of the engine, to avoid the car breakdown caused by external factors during the travel process due to engine damage.

Engine guard classification.

1. Hard plastic, resin guard board.

**Relatively cheap, the production process is simple, but it should be noted that this material guard is easy to break, and it cannot be repaired after the damage can not play a long-term protective role.

Advantages: light weight, low weight.

Disadvantages: Easy to damage.

2. Steel or manganese alloy guard plate.

It should be noted that when choosing this kind of guard, it is the matching of the style of its design and the car and the quality of the supporting accessories, and the products of regular manufacturers must be selected. The guard plate of this material can protect the important parts of the engine and chassis to the greatest extent, but the disadvantage is that the weight is heavy.

Advantages: strong impact resistance.

Disadvantages: Heavy weight.

3. Aluminum alloy protection plate.

Many beauty shops push this product, looking at the high profit behind its ** grid, but its hardness is far less than that of steel protection plates. Damage is difficult to repair, and the alloy material is extremely complex and difficult to determine its characteristics, but it is characterized by its light weight.

Advantages: Light weight.

Disadvantages: **High, material strength is not high.

If you decide to install the guards, be sure to look at the equipment in the construction area, as the construction of the guards is quite troublesome. First of all, it is necessary to carefully remove the oil stain of the chassis, use a special detergent to completely remove the asphalt and oil stains, and then dry it, any negligence in these treatments will affect the firmness of the guard plate. Then seal the parts that need to dissipate heat, such as the transmission shaft and other rotating systems, exhaust pipes, with tape or waste newspapers.

In order to avoid accidental damage and affect their normal operation, and remove these tapes or newspapers after the construction is completed to avoid danger.

Is it necessary to install the engine underguard? The professional technician told the truth.

For drivers who often run secondary roads or villages, it is necessary to install engine guards, which can play a role in protecting the engine.

The engine guard is an engine guard designed according to a variety of different models, which is designed to prevent mud from wrapping the engine firstly, and secondly to prevent damage to the engine caused by the impact of uneven road surfaces during driving.

It is necessary that if the chassis of the car is low, it is easy to catch the engine when driving on muddy roads. Installing a guard plate can protect you well, and it's not expensive. Just 200 yuan.

The engine underguard is coming from the car manufacturer.

Since a few years just launched to protect the engine bai with, why do you leave the factory new zhi car no, the reason dao is very simple is to increase income, these engine guards are not necessarily the original manufacturers, many are auto parts manufacturers do, of course, 4S shop strong launch, they are very profitable, but the benefits of installing are absolutely there, the car chassis is low if there is something in front of it will touch the engine, as for fuel consumption do not worry, almost unaffected, it is recommended to install one.

It is recommended that it is necessary to install it, and the main function of the lower guard plate is to protect the engine from impact when passing over uneven roads, and it can also ensure that the soil does not run into the engine compartment. Almost all luxury cars, such as BMW, Mercedes-Benz, etc., have a whole shield plate on the chassis, which is fully enclosed.

Say that there is no need to pretend, too copy generalization.

Whether you install it or not depends on what road conditions you often drive, the role is determined by taking into account environmental factors, the road conditions you drive are very good, very smooth, such as urban roads, it is recommended not to install; If the road conditions are not very good in the countryside, then put it on. Be nice to your engine oil pan

This is definitely needed, don't think about it.

New cars are now no one on this baffle, a lot of small gravel roads, when the car version is fast, the right to damage the engine is not small, and the pit is not good for a long time.

Or go back to your hometown or something, the road is full of potholes, and if you don't pay attention, you will touch the engine, who doesn't feel distressed.

To sum up, be sure to !!

Of course there is a need, especially to walk the potholed road!

I look at the road conditions that I often walk.

Come to the city to park the oil road since.

It's okay if you don't pretend. If only bai

I'm still a little worried, but I can buy a barrel chassis armor zhi, spray it on the oil pan, and do a lot of things.

If you have a gravel road, it is good to install it. If it really collapses to the bottom of the oil, I don't dare to guarantee that it will not leak, and the strength of the stone is still quite large.

There's no need, bai

Let me talk about the protection of the guard.

DU role. 1. Keep the engine compartment clean and prevent water on the road.

Dao mud ah into the engine compartment.

Expert. 2. Prevent the sand and gravel hard objects rolled up after the tires are rolled over during the driving of the car from hitting the engine. It will not have an impact on the engine in a short time, but it will still have an impact on the engine after a long time.

3. Prevent the scratching of the engine by uneven road surfaces and hard objects.

It is not necessary to affect the heat dissipation, which is not good

It should be installed in winter to keep warm.

It can be installed and it is necessary to install. Let's talk about the misunderstood shortcomings first, some people say that the engine guard plate consumes fuel, and when the guard plate first prevailed, there were steel plates. One piece weighs more than 20 pounds.

You put it on, you say that it consumes fuel but does not consume fuel, and it is not easy to break in the event of an accident, which affects the sinking of the engine. There is also said to have resonance, noise. Later, titanium alloy aluminum alloy guard plate was produced.

This comparison steel plate is relatively much lighter, but because it is light, the bearing capacity is not good, and the point is that it will resonate. Now, the more popular plastic steel guard, the plastic steel guard plate is light and the bearing capacity is not bad, the most important accident is easy to break due to the special installation method, will not affect the normal sinking of the engine. Because it is made of alloy plastic steel (PVC and a polymer material), it will not resonate.

Others say that plastic steel affects heat dissipation. However, those who have studied carefully know that the engine relies on water cooling to dissipate heat, and the main heat of the engine is dissipated by water circulation water cooling, not air cooling. The main heat dissipation method is the water cooling system, the water of the water tank, under the action of the water pump, flows to the part of the engine that needs to dissipate heat, and takes away the heat.

Only a small part is dissipated through the chassis. Moreover, when the speed of the car reaches 70, the wind speed is equivalent to a strong wind of 7 or 8 levels, when the car is driving, the heat is dissipated to the back and both sides, and the heat rushes to the top when it stops. When the car stops, the heat dissipation is generally based on natural emission, and it is rushed to the top, and the top is not finished rushing to both sides and back, so the heat dissipation will not be affected after the guard plate is installed.

Therefore, the landlord decides whether to install the guard plate and what material to choose. The landlord can make a reference.

Engine guards have a role.

Since the engine is a machine that converts chemical energy into mechanical energy, its conversion process is actually the process of the work cycle, simply put, it is through the combustion of fuel in the cylinder, generating kinetic energy, driving the reciprocating motion of the piston in the engine cylinder, thereby driving the connecting rod connected to the piston and the crank connected with the connecting rod, making reciprocating circular motion around the center of the crankshaft, and outputting power.

1. Body: It is the assembly base of each part of the engine. It includes the cylinder head, cylinder block, lower crankcase (oil pan). The cylinder head and the inner wall of the cylinder block together form part of the combustion chamber. Many parts of the body are part of other systems.

2. Crank connecting rod mechanism: It is a mechanism used by the engine to generate and transmit power, through which the linear reciprocating motion of the piston is transformed into the rotary motion of the crankshaft and output power. It includes pistons, piston pins, connecting rods, crankshafts with flywheels, and cylinder blocks, among others.

4. Fuel supply system: The fuel supply system of gasoline engine includes gasoline tank, gasoline pump, gasoline filter, air filter, carburetor, intake pipe, exhaust pipe, exhaust muffler, etc. Its function is to mix gasoline and air into a suitable combustible mixture and supply it to the cylinder for combustion, and exhaust the exhaust gases generated by combustion out of the engine.

5. Cooling system: mainly including water pump, radiator, phoenix fan, water distribution pipe, cylinder block and water jacket in the cylinder head. Its function is to dissipate the heat of high-heat parts into the atmosphere to ensure the normal operation of the engine.

6. Lubrication system: including oil pump, pressure limiting valve, lubricating oil channel, filter collector, oil filter and oil radiator, etc. Its function is to supply lubricating oil to the friction parts to reduce the friction resistance between them, reduce the wear of the parts, and partially cool the friction parts and clean the friction surface.

7. Starting system: including the starting mechanism of the engine and its auxiliary devices.

Many people are consulting about various matters of the car, and one fan asked: If you want to understand the function of the engine underguard, you may wish to take a look at my introduction, I hope to give you some help. The lower guard of the engine ensures that the engine oil pan can be activated, making the car's chassis smoother.

In this way, when the air is driving at high speeds, the airflow through the chassis will be faster and the stability of the car will be better.

Most cars have a guard plate under the engine to protect the oil pan. Some cars have plastic engine guards, while others have metal engine guards.

The under-engine guard makes the chassis smoother, so that the air flowing under the vehicle is faster and more stable at high speeds.

There are many high-performance cars or racing cars with completely sealed chassis. This kind of car has a lot of pressure when driving, which can improve the high-speed driving stability of the car.

If the air body passes through the chassis faster, the pressure under the chassis will be less, so the air above the body will press the car to the ground, so the stability will be better at high speeds.

Many SUVs have poor stability at high speeds. Part of the reason for this is that the chassis of SUV models is too high. There will be bumps when the air passes through the chassis, and the bumps will provide lift, so the SUV will always feel the body shake when driving at high speeds.

Most engine underguards have air holes that can also be closed to cool the engine. Some riders will convert the plastic fenders to metal, encouraging them not to modify the lower fenders casually, otherwise the engine will sink in the event of a collision.

Automotive engine guards are also part of the chassis planning of the car, which is primarily designed to optimize aerodynamics and heat dissipation in the engine compartment (making the chassis smoother, and optimizing drag and noise as air flows through the chassis at high speeds). Targeted heat dissipation of the guard plate makes the heat dissipation more stable during driving), and it can also have a certain effect on chassis protection!

Nowadays, the most common raw materials for automobile engine guards are mainly iron, aluminum alloy, plastic steel, and plastic, and some businesses call aluminum alloy titanium aluminum alloy, which is a gimmick to improve the first grade. The raw materials of plastic steel are similar to the raw materials of plastic steel windows that are common today, and have certain strength and resistance.

Iron trim plate. The strongest protection performance, moderate performance, can withstand high-intensity bumps. However, due to raw material factors, wet south and cold north, rain and snow corrosion is easy to rust after a few years of use, and the fixed bolts and screws are all corroded, which greatly increases the difficulty of disassembly and assembly. Another disadvantage is the occurrence of resonances, which sometimes occur when the fixing bolts are loose or when the guard plate comes into contact with the oil pan.

Aluminum alloy guard.

The weight is light, and the protective performance is inferior to that of iron guards.

Plastic steel guard plate. It is the same material as the plastic steel doors and windows at home, but the color is different. The amount is similar to that of aluminum alloy, and the raw material itself has strong resistance, and it is easy to deal with small scratches, but in terms of overall protective performance, it is not as good as aluminum alloy materials.

Plastic cladding plates. The weight is the lightest, and many models are equipped with plastic guards, which are first and foremost to reduce the drag coefficient. The protective performance of the plastic shield is the lowest among these types of guards, which can only play the effect of blocking sediment and resisting stones. If the plastic guard plate is installed in the later stage, it is necessary to pay attention to whether the distribution of the heat dissipation port is reasonable, and the long-term close contact with the bottom of the car engine is likely to have the risk of spontaneous combustion at high temperatures!
