The high-temperature water inlet jacket 27 is arranged at the upper right side of the intercooling water outlet jacket 26, and the high-temperature water outlet jacket 28 is arranged at the right side of the intercooling water outlet jacket 26.
Working principles: the two superchargers on the top of the box body 1 press air into a cover of the box body 1. After being cooled by the intercooler in the box body 1, the air enters left and right air intake main tubes through the air outlet 15 at the back face of the main body 2 of the box.
Oil enters an oil filter via an oil passage on the box body 1. Most of the filtered oil enters a main oil passage of an engine body via a casting cavity in the box body 1 by two passages, and the rest filtered oil is directly communicated with the supercharger oil inlet 19 and the supercharger oil return port 20 via an oil inlet passage and an oil return passage of the box body 1 to lubricate and cool a rotor shaft. The oil pressure regulating valve at the lower right part of the back face 2 of the box body can adjust the pressure of the oil entering the engine body, and the oil flowing through the oil pressure regulating valve retums to an oil bottom housing.
A high-temperature water pump at the front end of the box pumps cooled water into the high-temperature water inlet 24 of the box. The water enters a power unit via left and right passages for cooling, enters again the high-temperature water inlet jacket 27 in the box at the front end after being gathered via a water outlet main pipe of a cylinder head. The cooled water in the high-temperature water inlet jacket 27 enters left and right intercooler cooling passages via two passages to cool air passing through the intercooler. The cooled high-temperature water flows back to the high-temperature water outlet jacket 28 in the box and flows out of the box. The intercooling water pump pumps the water into the intercooling water inlet 22 of the box. After entering the intercooler water inlet jacket 25 of the box, the intercooling water enters the left and right intercooler cooling passages via two passages through a connecting tube, and cools the air cooled by the high-temperature water again. The 6 intercooling water after two-stage cooling enters the intercooling water outlet jacket 26, and then flows out of the box body 1.
The above description is only illustrative but is not restrictive for the présent invention. The person skilled in the art understands that many modifications, changes, or équivalents made without departing from the spirit and scope defined by the appended claims ail fall within the protection scope of the présent invention.
