1. Introduction
The engine guard is a guard engine various models of a given body design, which is designed to prevent dirt wrapped first engine, resulting in poor engine cooling, followed by 
Alloy steel engine protection plate in order to prevent the uneven road surface and engine damage caused by impact of the engine, through a series of design to prolong engine life, avoid trip during engine damage due to external factors during driving automobiles anchor.
2, engine guard classification
a hard plastic, resin protective plate
less expensive, simpler production process does not require a lot of investment and the high value of the equipment, the production of such guard low barriers to entry. But note that this material is easily broken fender especially in winter, in itself susceptible to broken beyond repair after injury will not achieve long-term protection. When
Second, the steel shield plate
However, this choice should be noted that the protective plate is the quality of matching and matching accessories style and design of cars, must choose regular factory product.
Third, the aluminum protective plate
should be noted that many of the beauty shop pushing this product, see is the high profits behind its high price, but it is far less than the hardness of the steel protective plate. Damage repair more difficult, extremely complex alloy is difficult to determine its characteristics.
Fourth, the alloy steel protective plate
alloy steel material developed in recent years of new polymer materials. The main chemical composition of a modified polymer alloy steel, also called copolymerized modified PP. It is characterized by light weight, toughness, compression and strong. Due to its physical properties such as rigidity, elasticity, corrosion resistance, excellent anti-aging properties, commonly used as copper, zinc, aluminum and other non-ferrous metals good substitute. Due to its excellent material properties, it has recently been used to make engine protection plate.
3. Application
First, the car type
such sheeting usually steel shield, because the car chassis from the ground are typically only about 20 cm, the first consideration is to prevent the uneven face of the engine drag hanging and impact. Of course, there are a lot of “limousine” aluminum alloy protection board.
Second, the mini-car type
mini cars, vans major manufacturers in the factory when installing a hard plastic, a resin protective plate, which shield generally only be able to have some protective effect of dirt road.
Third, SUVs
off-road vehicles are generally used for non-normal road driving, the engine guard is indispensable major components, manufacturers have been manufactured before each have a very strong steel shield mount .
4, the effect of engine guard
to keep the engine compartment clean, surface water to prevent dust from entering the engine compartment.
prevent the cars during the tire rolling the rolled sand hard objects striking the engine, engine knocking as sand hard objects of this phenomenon.
a short time will not affect the engine produced for, but a long time, the engine is still influential.
can also prevent uneven pavement and scratch hard objects touch on the engine.
drawbacks: hard protective engine guard may prevent the engine settle in a collision, the protective effect of weakening the engine sinking.
5, the selection engine guard
have four principal engine guard: hard plastic, resin, steel and aluminum. Different types of shield material, which is essentially different properties.
a hard plastic, a resin shield.
less expensive production process is simple, but requires injectionThis material is intended to shield fragile especially in winter, in itself susceptible to broken beyond repair after injury will not achieve long-term protection.
Advantages: light weight, low price
Disadvantages: easily damaged
Second, steel or manganese alloy shield. When
However, note that the choice of such boards, matching is the quality of the design and related accessories and car models, must choose regular factory product. And this material can shield the maximum degree of protection important engine and chassis parts, but the disadvantage is the weight and the sink.
Advantages: impact resistance
Disadvantages: heavy weight
Third, the aluminum protective plate.
It should be noted that many of the beauty shop pushing this product, see is the high profits behind its high price, but it is far less than the hardness of the steel protective plate. Damage repair more difficult, extremely complex alloy is difficult to determine its characteristics, but which is characterized by low weight.
Advantages: lightweight
drawbacks: high price, high material strength is not
Fourth Generation: Alloy steel protective plate. .
It is characterized by light weight, toughness, compression and strong.
Advantages: protection of steel alloy plate with a new innovative plastic polymer materials, tailored according to the original car, toughness, high temperature resistance, anti-collision.
Traditional protective plate to aging, easily deformed, resonance, rust, breakage.
Disadvantages: materials used are imported polymer, high construction cost, resulting in higher price of the product.
engine sink: one of the few leading brand has gained the patent technology, it does not affect the engine sink.
Currently on the market price of the shield far from uniform, ranging from several hundred dollars to, but basically substantially similar to a thousand dollars all places can guard the construction materials used, but is the manufacturer Different. Network would be best to opt for a regular car 4S shop or online store to buy, look for the brand product. Also, if you decide to install guard, be sure to place the construction optimisticConstruction equipment, guard quite cumbersome. First carefully remove oil chassis, the use of special detergents asphalt, oil, etc. is removed completely clean after drying, the shield will affect the firmness of these processes in any one of neglect. The transmission shaft is then rotated based, the need for cooling exhaust pipe portions spray sealed with tape or the waste paper. So as to avoid accidental damage, which affects their normal operation, and these tapes will be completed at the construction or demolition newspaper, to avoid danger.
guard frequently used in cement production process!
