Do you have engine guards on the chassis of your car?

Install a good engine guard plate is based on a variety of different models of design of the engine guard, its design is first to prevent mud to wrap the engine, resulting in poor engine heat dissipation, followed by to prevent the engine damage 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 due to external factors during the travel 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 not to cause accidental damage and affect their normal operation, and to remove these tapes or newspapers after the construction is completed to avoid danger.

Hello, engine guard I think it is very necessary to install one here for several reasons, the engine guard can prevent rain and snow weather sewage into the engine compartment, effectively reduce engine corrosion and rust.

Prevent small or large hard objects from being rolled up during driving to knock on the engine. Prevent oil leaks from the engine. Scratches or something.

It can protect the oil pan, and if the oil pan leaks, there will be no lubricating oil in the engine.

In order to reassure myself, I think it is necessary to install one, I recommend not to go to the 4S store to install it, because the 4S store is more expensive and not durable, just buy one yourself online It is easy to install, but it is necessary to consider heat dissipation and resonance and protection, to ensure the sinking space of the engine. Don't just go for sturdy. I didn't install it before, and then I went to buy a Jinke engine guard plate myself, which is quite cheap and easy to install.

If it is not installed, long-term driving will definitely pile up a lot of soil in the engine compartment, which not only increases the fuel consumption of the car, but also has a certain impact on the power.

Many cars are not equipped with engine baffles when they leave the factory, so some car owners want to be fresh and install baffles by themselves. However, some friends questioned the practicality of the baffle, thinking that it was just a boo for the merchants. So, is it necessary to install the engine baffle, and what are the pros and cons of installing the engine guard.

If you often drive on some low-lying roads or gravel roads, it is necessary to install the engine baffle. Otherwise, in the long run, a lot of soil will definitely accumulate in the engine compartment, which will not only increase the fuel consumption of the car, but also have a certain impact on the power. But on the contrary, if you usually only use the car to commute in the city, there is no need to install the engine baffle, after all, the road conditions themselves are very good, and adding another baffle may just be a futile effort.

The pros and cons of installing the engine guard plate first talk about the benefits of the engine guard plate, which can not only prevent the mud from wrapping the engine, but also effectively alleviate the impact on the engine when the car is driving on uneven roads, and play a protective role to a certain extent. As for the disadvantages of the engine guard, it is the problem of heat dissipation, but this impact can be said to be minimal. Because the heat dissipation of the engine mainly depends on the front grille, engine compartment design, water pipe and radiator design, only a small part of the heat is emitted from the chassis.

Therefore, you don't have to worry about adding the engine guard, which will affect the heat dissipation performance of the engine.

After the owner buys the car, the staff of the car 4S shop will suggest that the owner install the engine chassis guard plate for the vehicle, so is it necessary to install the engine chassis guard?

After the owner buys the vehicle, it is necessary to install the engine chassis guard for the vehicle, which belongs to a protective device of the vehicle, which can prevent debris on the road from adhering to the engine and chassis surface of the vehicle. Especially when the vehicle is driving on a low-lying road, the chassis guard plate is installed for the vehicle, which can prevent the mud on the road from splashing directly on the surface of the engine, wrapping the engine of the vehicle, and affecting the normal heat dissipation of the engine.

It can also prevent the vehicle from protruding on uneven roads, scratching the vehicle's oil pan, or scratching the vehicle's chassis. To sum up, when the vehicle is driving on uneven road surface, it is necessary to install chassis guard, if the owner buys the vehicle only for use in the city, this road surface will generally be relatively smooth, and the chassis guard plate can not be installed.

It is necessary to install the chassis guard. The scientific name of automobile chassis armor is automobile chassis anti-collision, anti-rust and sound insulation ("undercoating\"primer), a high-tech adhesive rubber bitumen coating. It has non-toxic, high coverage rate, high adhesion, can be sprayed on the vehicle chassis, wheels, fuel tanks, car lower panels, trunks and other exposed parts, after rapid drying to form a firm elastic protective layer, can prevent the impact of flying stones and gravel, avoid moisture, acid rain, salt on the vehicle chassis metal erosion, prevent the chassis rust and rust, protect the driving safety of the owner.

The functional features of the armor of the automobile chassis are as follows:

1. Chassis anti-corrosion: The rust of the car starts from the bottom plate, and you don't see it, and the side beams of the car that have only been running for three or five years have begun to appear rusty. The humid weather in the south, coupled with the fact that the sewage will remain at the bottom every time you wash the car, will form potential corrosion factors and cause damage to the car in the long run.

After the bottom of the car is cured, even acid rain, snow dissolving agent, and car washing alkaline water cannot erode through this protective film;

2. Anti-stone shock: the vehicle will splash small stones in the process of driving, the force of the stone impact on the bottom plate is proportional to your vehicle speed, generally 10 grams of small stones at a speed of 80 kilometers per hour when the impact force will reach 30,000 times its own weight, enough to break the paint film below 30 microns, once the paint film is broken and rusted, it will start from the defect and slowly expand from the inside of the iron plate. After the bottom of the car is cured, even the gravel cannot be broken with a force of 300 kilograms;

3. Shockproof: the engine and wheels are fixed on the floor of the car, and their vibration will resonate with the bottom plate at a certain frequency, making people feel uncomfortable, and the bottom protection will eliminate this resonance;

4. Heat insulation and fuel saving: in summer, turn on the air conditioning in the car and the cold air sinks, and the ground heat outside the car rises, and the hot and cold air is mostly concentrated on the floor of the vehicle for exchange, how the protection effect of the bottom of the vehicle directly determines the effect of the vehicle's refrigeration energy utilization, after the maintenance of the bottom of your car, the honeycomb tissue sound absorption factor in the membrane will completely isolate the cold and heat;

5. Sound insulation and noise reduction: when the vehicle is driving on the expressway, the friction sound between the wheels and the road surface is proportional to the speed, and the vehicle has a good bottom protection, which can greatly reduce the noise in the car;

6. Anti-drag bottom: the thickness of the bottom maintenance material can reach 1 5 2 5 mm, and when the bottom is scratched by the road protrusion, the damage to the chassis will be reduced; Especially on the highway, the road friction is very high, the sound is noisy, the chassis makes the noise very small, and the heater can maintain the temperature for a long time even if the heater is turned off due to the good insulation effect.

Nowadays, many people will install engine chassis guards for their cars, which can protect a series of hazards that may be caused to the engine or transmission during driving, after all, the engine and transmission are the two most important things for the normal driving of the car. But some people will worry about the impact on heat dissipation, etc., so is it necessary to install it?

Automobile engine chassis guards are still useful. It can protect the vehicle during driving and prevent damage to the engine caused by sand and gravel on the road. Secondly, the vehicle is protected from engine damage when the chassis of the vehicle comes into contact with a protrusion.

The engine guard is divided into two installation methods, one is assembled by the manufacturer itself, and the other is installed by the owner in the later stage. Although the models equipped with engine guards by manufacturers are generally high-priced models, we can think that even manufacturers believe that the installation of engine guards is feasible.

Some people are worried about heat dissipation and safety issues, but they are actually a bit too worried. Engine heat dissipation is more through the exhaust fan in the front grille than under the engine, and although it does a little, it has little effect.

Plastic material ** cheap, easy to install, for urban roads and other road conditions in good driving environment, the installation of this material of the guard plate can be, however, the protection of the engine is weak.

Protects against dust or fine grit. However, if the road surface is uneven, it will not protect the oil pan, water tank, gearbox or other components. Especially off-road is not suitable. In older cars, the engine dissipates heat slowly in the summer.

Aluminum guard plate This kind of guard plate is now loved by most people, and heat dissipation can also be used, and the cost is on the high side. In particular, there is good protection against bottom components (e.g. oil pans).

Alloy material The store is more highly recommended material, mainly because of the high profit, the effect on the owner is not big, once the damage occurs, it is not easy to repair, and it needs to be replaced directly.

The hardness of the steel plate is large, and once it encounters the bottom support, hanging friction, etc., the steel plate can hold up and is not easy to break. It will be a little more expensive on **. It is mostly used for off-road vehicles. If you use a car, the engine will sink, and the fuel consumption will increase due to the heavier weight.

High-strength polyester guard This kind of guard board is better, light in weight and hard in strength, but the cost is not low.

1. Effectively protect against damage to the bottom of the engine or gearbox due to the road bulge.

2. Protect and resist the mud and stones that are brought up or splashed by the wheels when the vehicle is moving.

Yes, the engine undercarriage plate engine is a machine that converts a certain form of energy into mechanical energy. Its function is to convert the chemical energy of liquid or gas into heat energy after combustion, and then convert the heat energy into mechanical energy through expansion and output power. The power of the car comes from the engine.

The engine is the heart of the car, providing power for the walking of the car, and the power, economy and environmental protection of the car. To put it simply, the engine is an energy conversion mechanism, that is, the thermal energy of gasoline (diesel) is converted into mechanical energy by pushing the piston to work when the combustion gas expands in the sealed cylinder, which is the most basic principle of the engine. All the structure of the engine is for the energy conversion service, although the engine has gone through more than 100 years of history with the car, whether it is in the design, manufacturing, technology or performance, control has been greatly improved, its basic principle is still unchanged, this is a rich creative era, those engine designers, constantly integrate the latest technology with the engine, turn the engine into a complex mechatronics product, so that the engine performance has reached a nearly perfect degree, The world's famous automobile manufacturers will also take the performance of the engine as a competitive highlight, first, the role of the automobile engine.

The automobile engine is a device that provides power for the car, is the heart of the car, and is an energy conversion device, which is to convert the thermal energy of gasoline (diesel) into mechanical energy by expanding the gas after combustion in the sealed cylinder, pushing the piston to do work. According to different power**, automobile engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrids.

Second, the classification of automobile engines.

1. According to the working mode of the air intake system, it can be divided into four types: naturally aspirated, turbocharged, mechanically supercharged and double supercharged.

2. According to the piston movement mode, it can be divided into two types: reciprocating piston internal combustion engine and rotary piston engine.

3. According to the cylinder arrangement type, it is divided into in-line engine, V-type engine, W-type engine and horizontally opposed engine.

6. According to the number of strokes, it can be divided into four-stroke internal combustion engine and two-stroke internal combustion engine. Four-stroke internal combustion engines are widely used in automobile engines.

7. Classified according to the way of fuel: carburetor engine and EFI engine and in-cylinder direct injection engine.
