KR970021678A - Internal combustion engine with independent combustion chamber - Google Patents

Abstract

The present invention relates to an internal combustion engine having an independent combustion chamber, and a configuration of the present invention includes a first cylinder having an intake port, an intake valve for opening and closing the inflow of air through the intake port, and reciprocating in the first cylinder. A first piston for performing suction and compression stroke, and a compressed air inlet valve communicating with the first cylinder and open at least in the time zone of the second stage of the compression stroke of the first piston to allow the inflow of compressed air; A combustion chamber including fuel injection means for injecting fuel into the compressed air introduced, a ignition means, a fuel gas discharge valve for discharging the combustion gas for a predetermined time region after the fuel injection and ignition, and a combustion gas in communication with the combustion chamber A second cylinder having a combustion gas inflow port supplied with the gas, an exhaust port, and an exhaust valve for opening and closing the exhaust port, and reciprocating in the second cylinder. An expansion stroke of the combustion gas and an exhaust stroke of discharging the combustion gas through the exhaust port are performed, and the first piston and the second piston are connected through the crankshaft.

With this configuration, the shape of the combustion chamber can be appropriately formed so that complete combustion of the mixed gas is achieved, thereby reducing the emission of pollution due to the complete combustion of the mixed gas.
