The engine guard plate is a protective device installed on the chassis of the car, which is mainly used to prevent the engine, oil pan, gearbox and other components from being eroded by road bumps, sediment, rain and snow. There are many materials for engine guards, such as steel, plastic steel, aluminum-magnesium alloy, etc. Different materials have different advantages and disadvantages, and are also suitable for different models and road conditions. So, is it necessary to install engine guards for family cars?This is a controversial topic, and different car owners have different opinions.
The main functions of the engine guard are as follows: to protect the engine. Since the bottom of the automobile engine is an oil pan, and the oil pan is relatively thin (heat dissipation), it is easy to deform, in order to avoid the deformation of the oil pan caused by roads and other factors, we can consider installing an engine guard plate to reduce the probability of oil pan deformation1. In addition, the three-way catalytic converter, gearbox and other components of some models are also susceptible to damage, and the engine guard plate can play a certain role in buffering.
Reduced wind resistance. After the installation of the engine guard, the bottom of the vehicle can be made more flat, thereby reducing the turbulence under the vehicle, and thus reducing the wind resistance, so as to achieve the purpose of reducing fuel consumption. Prevent the ingress of foreign objects. In some places with poor road conditions, the vehicle may encounter foreign objects such as stones, branches, and plastic bags when driving, and if there is no engine guard, these foreign objects may be stuck under the vehicle, affecting the normal operation of the vehicle, and even causing a fire. The engine guard can effectively block these foreign objects and ensure the safety of the vehicle.
The pros and cons of the engine guard plate are mainly as follows: Pros: It can effectively protect the engine and other components, reduce maintenance costs and accident risks, reduce wind resistance and fuel consumption, prevent foreign objects from entering, and improve the durability and safety of the vehicle. Disadvantages: It may affect the heat dissipation of the engine compartment, increase the burden on the cooling system, cause the engine temperature to be too high, and affect the life and performance of the engine. It may increase the weight of the body, affecting the handling and dynamics of the vehicle. It may affect the safe sinking of the engine in the event of an accident and increase the hidden danger of personal injury. It may increase the noise of the vehicle and affect the NVH of the vehicle.
The selection of engine guards is mainly as follows: according to the model and road conditions. Generally speaking, vehicles with high ground clearance such as off-road vehicles and SUVs, as well as vehicles that often drive in bad roads and mountain roads and other places with bad road conditions, need to install engine guards to prevent serious damage to the engine. For some models with low ground clearance, as well as vehicles that only drive on city roads, the need to install engine guards is less great, and it may even bring some drawbacks.
Choose according to the material and thickness. Different materials and thickness of the engine guard have different characteristics, generally speaking, the steel engine guard has high strength, wear resistance and crash resistance, but the weight is large, affecting fuel consumption and safe sinking. The engine guard plate of plastic steel is light in weight and has good air permeability, but it has low strength and is easy to deform or break. The aluminum-magnesium alloy engine guard plate is of moderate weight, moderate strength, and good heat dissipation, but it is high and easy to be stolen. Therefore, car owners should choose the right material and thickness of the engine guard according to their actual needs and budget.
Choose according to the installation method. The engine guard is mounted in two ways, either directly to the body or attached to the body by a suspension. The direct fixing method is relatively firm, but it is not conducive to disassembly and cleaning, and it is not conducive to engine sinking. The suspension device is more flexible, the height can be adjusted according to the road conditions, and it is also easy to disassemble and clean, and does not affect the sinking of the engine. Therefore, car owners should choose the appropriate installation method according to their own usage Xi and safety considerations.
Engine guard plate is a kind of pros and cons of auto parts, it can protect the engine and other components, reduce wind resistance and fuel consumption, prevent foreign objects from entering, improve the durability and safety of the vehicle, but it may also affect the heat dissipation of the engine compartment, increase the weight of the body, affect the safe sinking of the engine in the event of an accident, and increase the noise of the vehicle. Therefore, there is no absolute answer to whether it is necessary to install engine guards for family cars, and it is necessary to consider comprehensively according to various factors such as vehicle type, road conditions, material, thickness, and installation methods, weigh the pros and cons, and make a reasonable choice. At the same time, car owners should also regularly check and clean the engine guard plate to keep it in good working condition to avoid unnecessary troubles and losses.
