Supercharged engine and intercooling inlet pipe thereof

Abstract

The invention discloses an intercooling inlet pipe of a supercharged engine, which comprises an inlet main pipe and an inlet branch pipe communicated with the inlet main pipe. The bottom of the inlet branch pipe is provided with a bypass hole, and the bypass hole is communicated with the inlet branch pipe and an air cylinder of the supercharged engine. Compared with the prior art, the intercooling inlet pipe modifies a structure of the inlet branch pipe, the bypass hole communicated with the inlet branch pipe and the air cylinder are arranged at the bottom of the inlet branch pipe so that when gas flows into the air cylinder through the bypass hole, the differential pressure caused by the Venturi effect enables condensed water located at the bottommost end of the inlet branch pipe to be sucked into the air cylinder to be combusted, and the problem of accumulation of the condensed water is effectively solved. The invention further discloses the supercharged engine comprising the intercooling inlet pipe.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an intercooling intake pipe of a supercharged engine. The present invention also relates to a supercharged engine comprising the above-mentioned intercooled intake pipe. Background technique [0002] For a supercharged engine, the intercooler is an important component of the supercharging system. The intercooler is arranged between the supercharger and the engine intake pipe to reduce the intake air temperature of the engine. [0003] The temperature of the exhaust gas discharged from the engine is very high, the heat conduction through the supercharger will increase the temperature of the intake air, and the density of the air will increase during the process of being compressed, which will inevitably lead to an increase in the temperature of the air, thus affecting the charging of the engine Efficiency, which in turn affects the power of the engine, so if you want to further ...

AI Technical Summary

Problems solved by technology

Due to the setting of the partition plate 105 between the intake manifold and the intake manifold 104, the cross-sectional area A of the bottommost end 142 of the intake manifold 104 is smaller than the cross-sectional area of ​​the joint 141 between the intake manifold 104 and the cylinder, so the gas In the process of entering the cylinder through the intake manifold 104, the gas flow rate at the bottommost end 142 of the intake manifold 104 increases, and according to Panoulli's theorem, the pressure at the bottommost end 142 of the intake manifold 104 is less than that of the intake manifold The pressure at the joint 141 between the pipe 104 and the cylinder cannot take away the condensed water accumulated at the bottom end 142 of the intake manifold 104. With the increase of the engine working time, the condensed water will accumulate more and more. After a long time, it will be very May rust the bottommost end 142 of the intake manifold 104

In addition, the accumulation of condensed water is too large, and it is likely to enter the cylinder after parking, which will cause white smoke from the engine, difficulty in starting, and even flameout.
