    • PURPOSE: A mixed combustion engine using diesel and gasoline, a control method thereof, and a complex ignition type combustion system are provided to improve cold start performance as the system is ignited by a spark plug in a low load area. CONSTITUTION: Complex ignition type combustion system comprises a cylinder block(10), a spark plug(12), a diesel injector(13), and an electronic control unit(30). The cylinder block comprises a plurality of cylinders(11), and each cylinder is connected to intake(21) and exhaust manifolds. The spark plug and the diesel injector are placed in the cylinder. The electronic control unit sucks air to the cylinder if an operation zone is in a high load area, and performs compression ignition by spraying diesel to the diesel injector. The electronic control unit sucks mixed gas into the cylinder if the operation area is in a low load area, and performs spark ignition. The electronic control unit performs the compression ignition by spraying the diesel to an diesel injector if the operation area is between the high and low load areas.
    • 目的:提供使用柴油和汽油的混合燃烧发动机,其控制方法和复合点火式燃烧系统,以在低负荷区域的火花塞点燃系统时提高冷起动性能。 构成:复杂点火式燃烧系统包括气缸体(10),火花塞(12),柴油喷射器(13)和电子控制单元(30)。 缸体包括多个气缸(11),并且每个气缸连接到进气口(21)和排气歧管。 火花塞和柴油喷射器放置在气缸中。 如果操作区域处于高负载区域,则电子控制单元将气体吸入气缸,并通过向柴油喷射器喷射柴油来进行压缩点火。 如果操作区域处于低负载区域,电子控制单元将混合气体吸入气缸中,并进行火花点火。 如果操作区域在高负载区域和低负载区域之间,则电子控制单元通过将柴油喷射到柴油喷射器来执行压缩点火。

    • PURPOSE: A method for operating a reciprocating internal combustion engine is provided to secure more effective operation of the reciprocating internal combustion engine in a load range below a pre-set rotation limit speed. CONSTITUTION: A method for operating a reciprocating internal combustion engine is composed of a cylinder(2) having a scavenging air opening formed in a scavenging slot(4) and an outlet valve(3); an air-compressing supercharger group(7) having a turbine(9) driven by exhaust gas from a combustion chamber(22) of the cylinder; and a piston(5) for reciprocating in the cylinder along a running surface(6) between a bottom dead center position(UT) and a top dead center(OT). The compressed air is supplied as scavenging air(12) through the scavenging slot to the combustion chamber of the cylinder. At least one cylinder of the internal combustion engine longitudinally scavenged is operated in at least one pre-set first rotation limit speed to a 4-stroke mode.
