JPS58172428A - Air feed system with reciprocating compressor for engine - Google Patents

Abstract

PURPOSE:To improve efficiency of combustion and output substantially by using pressurized air fed to an engine with a reciprocating compressor. CONSTITUTION:Air is fed to an engine with conventional intake action of an engine itself and feeding air pressurized by a main reciprocating compressor so that the pressurized air is fed in the compression stroke of the engine. Then, the air pressurized by the compressor is once reserved in a tank and supplied to the engine through a feed valve opened and closed in synchronization with the engine rotation. Also, a sub-reciprocating compressor driven by exhaust gas is constituted to pressurize the prepressurized air with the main reciprocating compressor so that efficiency of utilization of energy can be improved further.

Description

Detailed Description of the Invention: By using a "reciprocating compressor" and tank with high air compression efficiency for the supply air of an engine (gas internal combustion engine), efficient combustion can be achieved under high air concentration and highly compressed air. Figure 1 shows a system that aims to obtain higher output.
Supplementary explanation 1) Air supply to the engine is conventionally carried out by separating the air supply from the engine itself and the air supply from the compressor into separate systems, and compressing the air supply from the compressor during the engine compression process. This is a system that pumps in a lot of air.

An example of how to synchronize the engine and compressor is a)
For a 4-cycle 4-cylinder engine, the compressor is a 2-cycle engine, so you can double the rotation of the compressor relative to the engine shaft, or b) You can make the compressor rotate at high speed relative to the engine and supply air by compressing it into the tank (engine compression In this case, the air supply method from the compressor is used.

2) This engine system effectively uses the effect of pushing down the piston during high-pressure combustion to discard low-pressure energy that does not have much force to turn the crank near bottom dead center.

3) Since the engine exhaust pressure is strong, energy can be used without wasting energy by adding a ``sub-reciprocating compressor'' that utilizes the output of the exhaust gas turbine and injects it into the tank of the ``main reciprocating compressor'' (see Figure 1). ``-'' 4) If it's a 4-cylinder engine, it can be made into an integrated 5-cylinder engine by adding another cylinder for the compressor. 5) If you increase the air compression effect of the compressor, it will have the characteristics of a diesel engine. In that case, it is better to use the fuel injection method because the engine combustion chamber looks similar.6) An example of an engine combustion chamber is shown in Figure 2.
