Two water pumps may be provided in the engine to supply water to the first and second water inlets 11 and 13, respectively.

This scheme provides one kind and has solved three hourglass of water pump, guaranteed that engine both sides temperature water pressure is unanimous, when guaranteeing that certain side water pump trouble the engine front end casing (be the shell structure) scheme that this side organism still can obtain timely cooling, increase the firm nature of water pump lubricating oil interface. The scheme has the following characteristics:

1. the scheme is that a water channel is arranged in a front end shell of an engine, the connection of a water pump to a water pipe of the engine body is optimized, the length of an external water pipe and a connector are reduced, leakage points are reduced, and three leakage faults are reduced. The water channel water pipes and the joints are reduced, and the fault probability of water leakage caused by large vibration of a long pipe is reduced.

2. The shell is arranged at the front end of the engine, the left side and the right side of the shell are communicated, a water channel is arranged in the shell, the pressure and the temperature of a high-temperature water pump at the left side and the right side entering the engine can be consistent, the problem that the water pump at one side fails can be solved, and water is automatically supplied to a machine body at the failure side at the other side. The water at the high-temperature and high-pressure side can be supplied to the side with relatively low temperature and pressure, so that the balance of the two sides is realized. When the water pump on one side fails and the machine body on the side cannot be cooled by the water pump, the water of the water pump on the side without failure can be automatically supplied to the other side for cooling the machine body on the side with failure.

3. The engine front end shell with the built-in oil duct can not only solve the problem of lubricating a water pump bearing, but also solve the problem of lubricating an idler shaft bearing, and due to the fact that the oil duct is symmetrical in the left side and the right side, the original connection of a water pump shaft, an idler shaft lubricating oil pipe and an oil inlet and return interface is omitted, and the oil leakage probability is greatly reduced. In addition, the oil pressure from the oil passage is larger than that of the original external oil pipe, so that the bearing can be lubricated better.
