A variable ignition type diesel-gasoline dual fuel powered combustion engine and control method can select spark ignition or compression ignition depending on the engine operating range. The variable ignition type diesel-gasoline dual fuel powered combustion engine includes a cylinder block formed of a plurality of cylinders each being connected to an air intake manifold sucking 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 engine operating ranges are judged by the speed and load of the engine. When the range is the high load range or the low load range, a gasoline fuel combustion is performed, and when the range is between the high load range and the low load range, a diesel-gasoline dual fuel powered step is performed.
A variable ignition type diesel-gasoline dual fuel powered combustion engine comprising:
A method for controlling a variable ignition type diesel-gasoline dual fuel powered combustion engine in which a spark plug and a diesel fuel injector are provided in the interior of a cylinder, and air or a gasoline-mixed air is introduced by way of an air intake manifold and is spark-ignited or compression-ignited in the interior of the cylinder, comprising:
A variable ignition type diesel-gasoline dual fuel powered combustion system which is formed of a plurality of cylinders, each cylinder being equipped with a spark plug and a diesel fuel injector, and air or a gasoline-mixed air is introduced into each cylinder, and an electronic control unit (ECU) is configured to control a gasoline fuel combustion, a diesel fuel combustion or a gasoline-diesel fuel combustion depending on an engine operating range, comprising:
