Water Inflow Of Air Filter Cannot Be Solved In Rainy Days? It'S Actually Leaking Here

As long as it rains, their trucks will have the problem of insufficient power and high fuel consumption. It’s normal at ordinary times, but I’m afraid of rainy days. Why on earth?Becourse water inflow of air.

In fact, there are many reasons for this problem. For example, the resistance of water on the road to the tire is much greater than that on the dry road, which will more or less increase the driving resistance of the truck. However, this is not the one that has the greatest impact on the power. The most common causes of insufficient power of trucks in rainy days are circuit failure and water inflow of air
The lack of power caused by water inflow of air in the circuit is indeed one of the troubles for card friends. Because the fault point is too difficult to find, it must be handled by professional maintenance personnel through professional testing equipment and rich maintenance experience, which is beyond our own processing capacity. I will not elaborate here. Today, let’s focus on how to solve the power shortage caused by water inflow of air filter.

Water entering the air filter is a very troublesome problem. Say it’s a fault. As long as it doesn’t rain, it won’t have any impact. Say it’s not a fault. You have to replace the air filter every time it rains, and you have to bear the losses yourself. Many card users have tried their best to solve the problem of water inflow into the air filter.
In fact, as long as you find the right part of the water inflow of air, the problem of water inflow of air inlet is relatively simple to solve. Most people think that the location of water inlet is the air inlet, while ignoring other possible locations of water inflow of air inlet. Because the air of the engine is sucked in from here. If it rains, it will certainly enter from here, but is this the case?

The real situation is not like this. I tested it before. After starting the engine, I sprayed water directly into it with a water pipe. As a result, the filter element was not wet by water at all. Because the interior of the water inflow of air has been designed to be waterproof, the water cannot enter the next link with the air at all. In addition, the interior of the air inlet is a swirling air strainer, which will be intercepted even if there is a small amount of entry. Therefore, the inlet water can be basically eliminated.

A large part of the culprit causing the water inflow of the air filter is caused by the lax sealing of the connecting part between the back air inlet of the cab and the air filter shell. Because the lifting of the cab should be considered, there is no way to make this part into an integral fully enclosed structure, and only rubber expansion joints can be used to seal it.

With the aging and deformation of the rubber expansion joint, water can easily enter the air filter from here. But most of us are hard to notice this little detail, let alone make targeted improvements. If your air filter often gets water, you can make a sealing modification here, and nine times out of ten, you can cure the maddening water inlet problem of the air filter.
