The sprayer supplies liquid to clean the surfaces of the cooler 7 over which the air passes. The liquid is supplied to the cooler from a reservoir 15 having a partition 23 which divides off the left hand part to form a settling chamber for dirt. A vent 24 allows the escape of air which has passed through the line 14.

    (54) ENGINE FOR INTERNAL COMBUSTION
    The invention relates to mechanical engineering, in particular to devices for internal combustion engines with supercharging, and with a charge air cooler. Internal combustion engines are known that contain at least one turbocharger, charge air cooler with nozzles for spraying washing fluid on its frontal surface, and a moisture separator installed between the cooler and the receiver of the engine and connected via a choke to the washing fluid drain line 1. Known engines have a choke made adjustable and its cross section depends on the attention of the operator. If the operator forgets to shut off the throttle, a compressed air leak is possible. In addition, the operator must take care to open the choke in time to drain the washing liquid. Therefore, the reliability of the known drain systems cannot be considered sufficient. The aim of the invention is to increase engine reliability. This is achieved by the fact that the choke is made with a constant flow section. constitute from 0.01 to 0.2% of the front surface of the cooler. As a result, the air flow through the drain pipe is at most one percent of the charge air cooler flowing through the cooler. As a result, the size of the throttles are so small that it does not have any influence on the conditions of operation of the engine. FIG. 1 dan proposed engine; in fig. 2 - sprinkling and draining system. Engine 1 has an exhaust manifold 2 and an air receiver 3 for charging air. The exhaust gas collector 2 is connected to turbines of a group of turbo-compressors 4, of which exhaust gases are discharged through pipe 5 to exhaust gases (not shown). The superchargers of the turbocharger group supply air through the air duct 6 with the charge air cooler 7 to the receiver 3. At the junction of the air duct 6 of the passage and the receiver 3 a moisture separator 8 is installed, which has deflecting partitions and
    flange 9 for fastening the main line of draining liquid.
    As can be seen from FIG. 2, in front of the cooler. M. 7 of the charge air, a device 10 is disposed for spraying washing liquid on the front surface. This device contains a spray pipe 11 with nozzles. 12 connected to a joint distribution pipeline 13.
    The flange 9 of the water separator is connected to the main 14 of the drain of washing liquid leading to the tank 15. In the main 14 there is a throttle 16, which has the shape of a diaphragm 17 fixed between two flanges 18 and 19.
    The suction pipe 20 is connected to the tank 15 with a pump 21, which supplies the washing liquid from the tank 15 through the feed pipe 22 to the spraying device 10. The container 15 is provided with a partition wall 23, which limits the space for contaminants discharged from the washing liquid and has a vent nipple 24 for exit of the charge air entering the main 14. In addition, the tank 15 is equipped with a bypass pipe 25, which when accumulating condensate serves to drain excess liquid.
    During operation, the air is compressed by the turbochargers and through the air line 6 through the cooler 7 enters the receiver 3 of the Engine and is used to fill its cylinders during operation. In the process of long-term operation, the dust particles contained in the air settle on the surfaces of the cooler and reduce its efficiency ..
    In order to remove these particles, a washing liquid is sprayed through the nozzles 12 onto the front surface of the cooler. In the dehumidifier 8, the washing liquid is separated, flows to the lowest point, and from there flows through the conduit 22 to the container. Together with the fluid on the line is looking for a leak of compressed air.
    Since the throttle cross section is designed to leak approximately 1% of charge air, this leakage has almost no effect on the workflow, and a constantly open throttle eliminates the possibility of fluid accumulation in the dehumidifier and its sudden throw into the engine.
