Should the car be equipped with engine guards?

There are pros and cons to installing engine guards, the biggest benefit is that it protects the engine, but there are problems such as affecting heat dissipation.

Advantages of the Orange Engine Guard: Prevent particularly heavy stone strikes and damage to chassis heavy parts (e.g. breakdown of engine oil pan or transmission housing) under extreme bad roads. For vehicles with low chassis, it is necessary to prevent the damage of automobile chassis parts caused by the bottom support.

In addition, it can also prevent the debris rolled up by the tires from hitting the engine oil pan, causing oil leakage and injuring the engine. The under-engine guard improves the smoothness of the chassis and reduces the forces caused by air flow.

The disadvantages of installing the engine guard, such as it will affect the heat dissipation of the engine, after all, it must be close to the engine cracking, which will affect the ventilation and heat dissipation of the engine is in the process of cleaning. In addition, it will increase fuel consumption, after all, the increase in weight will also increase fuel consumption accordingly. Older models are equipped with engine guards, and when the car has a huge collision, the engine guards block the engine from falling, which will cause the safety of the people in the car to be unguaranteed.

Therefore, if you want to install the engine underguard, it is best to choose according to your actual needs.

1.Benefits: When driving at high speeds, the wheels will roll up debris on the ground, such as mud, sand, leaves, rain, etc. These can cause some corrosion to the exposed parts of the car chassis. To protect these parts, the loss of these parts can be avoided by installing an engine guard.

2.Hidden dangers: No matter what kind of car you design, you should consider safety.

In general, when a car encounters a major collision, the engine sinks. The aim is to prevent the good orange engine from being moved back into the cabin, which could cause injury to the occupants of the vehicle. However, if the engine is equipped with a guard plate, in the event of an accident, the sinking function of the engine will be blocked, thus increasing the hidden danger of injury to the occupants of the car.

Note: As an engine protection device, the model without the engine guard plate is different, and it is tailor-made. It is designed firstly to prevent mud from wrapping around the engine, and secondly to prevent damage to the engine due to the impact of uneven road surfaces during driving.

Through a series of designs, the service life of the engine can be prolonged, and the car can be avoided from breaking down due to external factors that cause engine damage and dust.

1.Benefits: When driving at high speeds, the wheels will roll up debris on the ground, such as sand, leaves, rain, etc. All of this can corrode the exposed parts of the car's chassis. In order to protect these parts, the loss of these parts can be avoided by installing a trapping motor guard.

2.Pitfalls: No matter what kind of car you design, you have to think about safety.

Generally speaking, when a car encounters a major collision, the engine will, in order to prevent the engine from moving back to the cab, thus causing injury to the occupants of the car. However, if the engine is equipped with a guard plate, in the event of an accident, this energy of the engine will be blocked, thus increasing the hidden danger of injury to the people in the car.

3.Note: As an engine protection device, the engine guard plate of the model is the same, and it is all tailor-made Lu Hall Nian.

It is designed firstly to prevent mud from wrapping around the engine, and secondly to prevent uneven road surfaces from impacting the engine and damaging it. Through the design of the train, the service life of the engine can be extended and the car can be prevented from breaking down due to external factors that cause engine damage.

Advantages: When driving daily, the speed is fast, and the wheels will roll up the debris on the ground, such as silt, leaves, rain, etc. These things may cause some corrosion to the exposed parts of the car's chassis. To protect these parts, engine guards can be installed to avoid the loss of these parts.

Pitfalls: No matter what kind of car you design, you have to think about safety. Under normal circumstances, when a car encounters a major collision, the engine will sink in order to prevent the engine from moving back to the cabin, thereby causing injury to the occupants of the car.

However, if the engine is equipped with a guard plate, the sinking function of the engine will be hindered in the event of an accident, which will increase the risk of injury to the occupants of the vehicle.

Note: As an engine protector, models without engine guards are different. It's all tailor-made.

It is designed first to prevent mud from wrapping around the engine, and secondly, to prevent damage to the engine due to the impact of uneven road surface on the road. Through a series of designs, the service life of the engine can be extended and the car failure caused by engine damage caused by external factors can be avoided.

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.

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.
