Gasoline-diesel complex combustion engine

Abstract

A gasoline-diesel complex combustion engine may include a cylinder including a cylinder body in which a combustion chamber is formed to generate a driving power by combusting a gasoline fuel and a diesel fuel and a cylinder head formed to cover an upper portion of the cylinder body, a pair of intake ports formed in the cylinder head, a pair of exhaust ports formed in the cylinder head, a diesel injector disposed in a center of the cylinder head, a pair of spark plugs disposed on opposite sides of the diesel injector, a first intake pipe and a second intake pipe mounted in the intake ports, an exhaust pipe mounted in the exhaust ports, a pair of intake valves disposed in the first and second intake pipes, and a gasoline injector disposed in the first and second intake pipes to inject the gasoline fuel into the combustion chamber.

Description

[0001] Cross-references to related applications [0002] This application claims priority from Korean Patent Application No. 10-2015-0178660 filed on December 14, 2015, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to a gasoline-diesel complex combustion engine, and more particularly, to a structure of a gasoline-diesel complex combustion engine driven by using a mixture of gasoline fuel and diesel fuel. Background technique [0004] Generally, a diesel engine has excellent fuel efficiency, but emits many polluting substances such as nitrogen oxides (NOx) and the like. On the other hand, gasoline engines have relatively low fuel efficiency, but emit less polluting substances, such as nitrogen oxides (NOx), etc., than diesel engines. [0005] Recently, exhaust gas management for diesel engine vehicles has become stricter, so development of new diesel engines has been required. [00...

Problems solved by technology

[0010] In addition, the distance the flame propagates from the ignition source of diesel fuel to the total fuel obtained by mixing gasoline fuel and diesel fuel depends on the position of gasoline injectors, diesel injectors, etc. in the combustion chamber and the combustion in conventional gasoline-diesel compound internal combustion engines The shape of the chamber increases, so the detonation can be increased
