Description

[Detailed description of the invention] The present invention relates to a supercharger mounting device for an internal combustion engine equipped with a supercharger and an intercooler, which allows the supercharger and intercooler to be arranged compactly and effectively removes condensed water generated in the cooler. It was designed to be removed.

By the way, in an internal combustion engine equipped with a supercharger, it is customary to cool the combustion air pressurized by the supercharger in an intercooler before supplying it to the combustion chamber. As a result, a complex arrangement of superchargers, intercoolers, and piping to connect them was made.
A large space is required at the end, and work efficiency in maintenance, inspection, etc. in the vicinity is significantly hindered.

Additionally, when the air pressurized by the supercharger is cooled by the intercooler, the moisture contained in the air condenses and forms water droplets, but conventional methods have not been able to effectively remove this. Because they were unable to do so, they received reports that they could enter the combustion chamber and rust the intake and exhaust valves, or inhibit combustion.

The turbocharger mounting device of the present invention was developed in view of these circumstances. An L-shaped bracket consisting of a horizontal section and a vertical section is attached to the end face of the engine, and the supercharger is mounted on the top of the bracket. The intercooler is housed in the space formed by the lower surface of the horizontal part and the inner surface of the vertical part, and the inside of the bracket is used as an air passage connecting the cooler and the air supply pipe, so that the supercharger and intercooler can be It is arranged compactly at the end of the engine, thereby creating extra space around the end, improving the workability of various operations, and making the air passage formed in the bracket curved. By doing so, condensed water is effectively removed from the air passing through the passage.

This will be explained below with reference to the embodiment shown in the drawings. In Fig. 1, 1 is an engine, and 2 is a bracket attached above one end face 1a of the engine at the rear surface 2a, as shown singly in Fig. 2. It has an L-shape consisting of a horizontal part 3 and a vertical part 4, and a supercharger 5 is placed on the upper surface 2b of the L-shaped part.
An intercooler 6 is housed in the space formed by.

The bracket is hollow, and the hollow part is an air passage 7 having an inlet lower part a on the front surface 4a of the vertical part and an outlet lower part b on the upper surface 2b. An air outlet 6a is directly connected, and an air supply pipe 9 is connected to the lower casing outlet b via a bent pipe 8.

Here, a drain hole 7c is formed at the bottom of the passage 7.

10 is a connecting pipe connecting the blower outlet 5a of the supercharger 5 and the air port 6b of the intercooler, 11 is an exhaust pipe connected to the turbine port 5b of the supercharger, and 5c is an air intake port of the supercharger. , 5d is the exhaust outlet.

According to the above configuration, the supercharger 5 is mounted on the upper surface 2b of the bracket 2 attached to the end surface 1a of the engine 1, and the supercharger 5 is formed by the lower surface 3a of the horizontal portion 3 and the front surface 4a of the vertical portion 4 of the bracket. Since the intercooler 6 is housed in the space where the intercooler 6 is located, and the inside of the bracket is used as the air passage 7 that connects the cooler and the air supply pipe 9, the supercharger 5 and the cooler 6 are connected to the end of the engine 10. It is compactly arranged and the connecting piping is extremely simple.

Furthermore, since the air passage 7 is a bent passage having an inlet lower a on the front face 4a of the vertical portion and an outlet lower b on the upper surface 2b, the air passing through the passage collides with the inner wall surface of the bracket. As a result, the condensed water generated in the cooler 6 is effectively separated from the air.

Here, the separated condensed water is drained from the drain hole 7c at the bottom of the passage.
However, the hole may be provided with an opening/closing cock so as to be discharged at an appropriate time.

Moreover, a frame 1 as shown in FIG.
By installing a moisture removal device 12 in which gutter-like baffles 12b are arranged above and below 2a, condensed water in the air flowing into the passage in the direction A from the cooler can be more effectively removed. You can.

As described above, the turbocharger mounting device of the present invention attaches an L-shaped bracket consisting of a horizontal part and a vertical part to the end face of the engine, and mounts the turbocharger on the top surface of the bracket. The intercooler is housed in the space formed by the front surface of the bracket, and a bent air passage connecting the cooler and the air supply pipe is formed within the bracket. It is arranged compactly at the end of the engine, and the piping for connecting these parts is extremely simple. In addition, the condensed water generated in the intercooler is effectively removed, which prevents the intake and exhaust valves from flowing into the combustion chamber. This has the effect of preventing reports of rust or combustion being inhibited.
