  • Patent number: 11111865
    Abstract: A compression ignition engine with a supercharger is provided, which includes one or more valves configured to switch a state between a first state where intake air is boosted by the supercharger and a second state where it is not boosted, a fluid temperature adjuster configured to adjust a temperature of engine coolant to be supplied to a radiator from an engine body, and a controller. When the engine operates in a high-load range, the controller controls the combustion mode to be in a compression ignition combustion mode, and causes the valve(s) to be in the first state, and in a low-load range, the controller causes the valve(s) to be in the second state. In the high-load range, the controller outputs a control signal to the fluid temperature adjuster so that a target temperature of the engine coolant is lowered than that in the low-load range.

  • Patent number: 11111846
    Abstract: In certain embodiments, Lube Oil Controlled Ignition (LOCI) Engine Combustion overcomes the drawbacks of known combustion technologies. First, lubricating oil is already part of any combustion engine; hence, there is no need to carry a secondary fuel and to have to depend on an additional fuel system as in the case of dual-fuel technologies. Second, the ignition and the start of combustion rely on the controlled autoignition of the lubricating oil preventing the occurrence of abnormal combustion as experienced with the Spark Ignition technology. Third, LOCI combustion is characterized by the traveling of a premixed flame; hence, it has a controllable duration resulting in a wide engine load-speed window unlike the Homogeneous Charge Compression Ignition technology where the engine load-speed window is narrow. Adaptive Intake Valve Closure may be used to control in-cylinder compression temperature to be high enough to realize the consistent auto ignition of the lubricating oil mist.
