Good roads in Russia are rather exception than the rule, so damage the engine crankcase on our roads is very simple: covered with snow curb, loose lid, deep pit and so on. The list is quite large, so many car owners ask how to protect the oil crankcase engine and whether it needs protection at all. About this further in the article.

What is a car carter

Carter is one of the main parts of the DVS. This element is fixed and can be mounted not only on the power unit, A and on the gearbox and other devices and vehicle mechanisms. Carter is a support of different working details. In addition, it is used as protection against getting into various details of garbage, dust and dirt. Carter has a lower and upper part. As for the lower part of its design, it is not rarely used as a container for lubricant.

Why driver safety and front passenger may depend on the protection of the crankcase during the front collision

Different car manufacturers belong to the protection of the oil crankcase in different ways. In most models, the engines from the bottom are absolutely open. And this is reasonable. Designers are trying to make it easier to ease the weight of the vehicle and ensure the best conditions for cooling the power unit to achieve the optimal indicators of the car in economy, pickup and power.

Not the last role is played out and considerations of ensuring the safety of the front passenger and the driver under conditions of a frontal collision. In this case, the power unit should not go into the salon, and down.

Protect or not protect the car crankcase why it is relevant to our roads

Even in the most civilized cities of Russia, the conditions for driving a car with low road clearance are far from ideal. Bricks and stones on the roads are not rare, not to mention the resulting ughabes and pits. In winter, deep ice rhesis appear on them. In addition, whatever the driver would be experienced, sometimes there are such situations on the roads when it is impossible to notice in a timely manner and drive around the pit on the road or a stone.

To protect individual parts and knots from dirt and dust, manufacturers are used by plastic covers and rubber anthers that are not able to save them from damage during the receipt of strong blows. So, when designing cars, designers do not take into account the movement of off-road, as well as inexperienced motorists driven by borders and stones. SUVs have high clearance for this.

But it cannot be said that manufacturers fully ignore this question. Many of them make regular protection of the motor crankcase as an additional accessory to the TC set, and provide in the bottom of the holes with threads for fastening protection. Thus, the buyer can solve himself, to establish protection or not.

Under what conditions are better to install Carter's protection

In principle, it all depends on the model and purpose of the car, the conditions of its operation and the driver's experience. If the car has high clearance and it is operated only in the city on the roads of the European level of asphalt type careful and experienced motorist without bad habits, it means that protection can not be set. In this case, the risk of receiving strikes along Carder is very small. In other cases, the ceter protection is better to install.

What can damage the bottom of the crankcase

Carter is a pallet of a motor that contains motor oil, from where it is drawn to cool and lubricating the crank-connecting and piston system. In the passenger car, it is located below other elements of the bottom and closest to the surface of the Earth. Just measured the road clearance of the car. There are steel and cast-iron crankcase pallets, and on some models - plastic. During a strong impact of a solid and hard object like a concrete curb, a sewer hatch or stone cover, the pallet may be deformed or crack.

Celers, which have appeared from the blows of any foreign objects about the bottom of the Carter, are able to break the operation of the oil pump and lead to the fall of oil pressure. The oil leakage is and leaked through a crack or samples in the pallet. As a result - overheating and outlet of the engine is out of order, and its repair will be as much as expensive than the acquisition and installation of protection.

Carter protection, which is protection

Carter protection is a rigid composite or metal sheet, which is designed to prevent solid items on the bottom of the power unit. It is mounted in front of the shield. His task is to take the energy of impact on itself and transmit it to the power components of the frame and chassis, protecting the motor. Therefore, the shield must be attached exclusively to the bearing frame structures.

In the modern market there is something to choose the protection of the crankcase. Manufacturers offer different samples of products from composite materials, aluminum and steel. Each of the proposed variations has its advantages and disadvantages.

Carter protection in the form of a shield from stainless steel, pros and cons

Stainless steel shields have good strength and is well opposed to repeated impacts, and also differ in low cost. The shortcomings can be attributed to the high weight of the product.

Aluminum Sheet Carter Protection, Pros and Cons

The protection of the crankcase made of aluminum sheet by strength is somewhat inferior to the steel shield, but weighs significantly less than it. Benefits, in addition to low weight, its high resistance to corrosion belongs. At the cost much higher than the steel counterpart. Weak place is the ears of the attachment.

Carter protection CARBON composite, pros and cons

Carboral composite protection is the most practical and durable design, which protective properties exceeds other types of shields. Its advantages are lightness, high strength, resistance to the effect of aggressive substances. The main disadvantage is the high cost of the product.

What are the requirements for Carter Protection

• The high rigidity and strength of the structure is provided by a sheet thickness, as well as the presence of longitudinal ribs or a special profile.
• The presence of technological holes in order to provide access to the drain crankcase corks during the maintenance of the motor.
• It is necessary that the elements of the fastening of the sheet ensure reliable and durable connection to the frame that will endure the blows of solid objects.
• It is necessary that the protective sheet does not interfere with the heat transfer by blowing the engine with air flow and did not deteriorate its natural cooling.
• It is necessary that the protection profile ensures the air gap in two or three centimeters from the crankcase pallet, however, it did not significantly reduce the clearance of the vehicle.
• A protective sheet with a plurality of ventilation gaps and technological holes has a slight strength, so their quantity must be minimal.

Carter Protection Rules

• Raise the car on the lift or put on the pit.
• Systems for fastening protection on various models of cars differ insignificantly. In the set of fasteners, they can have brackets, bolts or nuts. As a rule, the protection guide is attached to the defense itself with a description and scheme. Most often, protection has in front of two or three holes under the fastening bolts, and behind - two ears or wide slits under nuts with washers.
• Install the required mortgage nuts, brackets, align the installation holes on the bottom of the car and protect, then tighten the fastening bolts.

Tips Prof.

When choosing a crankcase protection for your car, pay attention to such moments:

1. Reliability of fastening components.
2. The presence of light grateproof plugs and covers on technological hatches intended for replacing the filter and oil.
3. The presence of damper pads to prevent the knock on the defense system.
4. The presence of a special coating for steel products from premature corrosion.
