Abstract

PURPOSE:To suppress an increase of the charging air temperature and to simplify the structure of an intercooler by injecting an inflammable liquid with large heat of vaporization to the charging air fed from a supercharger in a supercharged engine. CONSTITUTION:A supercharger 3 is provided on the passage of the exhaust pipe 2 of an engine 1. One end of a pipe 9 is opened 6 to a charging air pipe 4 and the other end is opened to a tank 7. An inflammable liquid with large heat of vaporization is stored in the tank 7. A control box 11 controls the aperture of a flow control valve by feedback so that the temperature of the charging air fed into a cylinder is kept at a predetermined value by comparing the temperature signals from temperature sensors 10, 10'. Accordingly, the structure of an intercooler can be simplified and its efficiency can be improved. In addition, the possibility of its damage is low and the risk is small that foreign objects may mingle in the charging air.

Description

【発明の詳細な説明】 本発明は、従来とは異なる手段による過給機付エンジン
のインタークーリング方法及び装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for intercooling a supercharged engine by means different from conventional means.

過給機付エンジンの一般的なデメリットは、過給機より
Ｉモ送される給気が断熱圧縮によってａｕｇとなったま
まシリンダーに供給されることに起因する。A general disadvantage of a supercharged engine is that the charge air sent from the supercharger is supplied to the cylinder as aug by adiabatic compression.

水が混入する恐れがある。In order to reduce this increase in supply air temperature, conventionally an air-cooled or water-cooled intercooler is placed in the supply air pipe connecting the supercharger and cylinder, but effective heat absorption (intercooling) is required. This requires complicated and large equipment, and the cooling pipes are easily damaged (there is a risk that air or water may get mixed into the air supply).

本発明は、このインタークーリングに液体の蒸発潜熱を
利用すること、その液体を過給機からの給気中で自接に
蒸発させることを特徴とする特許たがって、本発明では
インタークーリングに使用する液体は可燃性である必要
がある。The present invention uses the latent heat of vaporization of the liquid for this intercooling, and the liquid is self-evaporated in the air supplied from the supercharger. The liquid must be flammable.

本発明の方法は、例えばアルコール、エーテル。The method of the invention uses, for example, alcohols, ethers.

機に接続した給気管のシリンダー側内にｌＩ制づること
である。・ 哨剖によって前記液体は給気管内で即時蒸発しその潜熱
により、周辺の給気から熱を吸収づる。This is to condense a flammable liquid such as gasoline with a large latent heat of vaporization into the cylinder side of the air supply pipe connected to the supercharger. - The liquid immediately evaporates in the air supply pipe due to the patrol, and its latent heat absorbs heat from the surrounding air supply.

1lffill efficiently lowers the supply air temperature.

熱Ｃ吸収される拳に比例覆るから、液体の噴１）１％は
給気の温度に応じて増減、すなわち、比例さける。In this method, since the drop in the supply air 2111 is proportional to the amount of latent heat of vaporization C absorbed by the liquid, the liquid jet 1) 1% increases or decreases depending on the temperature of the supply air, that is, it is proportionally avoided.

An air supply pipe 4 connected to the supercharger 3 has one end opened 6 on the cylinder side and the other end opened 8 in a tank 7, and a liquid is supplied under pressure to a pipe 9 communicating between the inside of the air supply pipe 4 and the tank 7. A pump P and a flow rate regulating valve V are arranged. The tank 7 is filled with the above-mentioned liquid which is flammable and has a large latent heat of vaporization.
