Problems solved by technology
[0009] However, the above-mentioned mixed combustion of gasoline and diesel fuel has a problem to be solved, in other words, the compression ratio decreases in the low load range, so that it is difficult to achieve the designed ignition performance due to the strict exhaust gas recirculation (EGR) condition, so in Knock problem due to high compression ratio in high load range

The invention discloses a System and method for controlling a variable ignition diesel-gasoline dual fuel powered combustion engine. The variable ignition diesel-gasoline dual fuel powered combustion engine can select spark ignition (SI) or compression ignition (DI) depending on the engine's operating range. The engine may include a cylinder block formed of at least one cylinder each being connected to an air intake manifold supplying air or a gasoline fuel-mixed air and an exhaust manifold exhausting an exhaust gas after combustions; and an ECU controlling the combustion modes. The ECU is configured to judge the engine's operating ranges of an engine depending on the speed and load of the engine, and when the range is the high load range, only the diesel fuel is combusted, and when the range is the low load range, only the gasoline fuel is combusted, and when the range is between the high load range and the low load range, the diesel and gasoline fuels are mixed and combusted.
Description
[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2011-0135575 filed in the Korean Intellectual Property Office on Dec. 15, 2011, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The invention relates to a gasoline and diesel dual fuel power engine with variable ignition type, its control method, and a gasoline and diesel dual fuel power combustion system with variable ignition type. More specifically, the present application relates to a gasoline and diesel dual-fuel power engine with variable ignition type, its control method, and a gasoline and diesel dual-fuel power combustion system with variable ignition type, which can select spark ignition or Compression ignition. Background technique [0004] In gasoline engines, if the compression ratio is high, it is good for combustion, but it will cause knocking problems. [0005] There is a...
