  • Patent number: 10208651
    Abstract: In certain embodiments, a unique method and pre-combustion chamber (PCC) structure may ensure very efficient flame propagation of lean fuel-air mixture in natural gas engines by reducing the amount of fuel admitted to the PCC. A PCC may include an enclosed volume of 1-3% of the main combustion chamber volume, with a spark plug and a fuel passage located opposite one or more PCC discharge nozzles to create a relatively richer fuel-air mixture with relatively lower turbulence in the spark plug region and a relatively leaner fuel-air mixture with relatively high turbulence in the nozzle region, which can be reliably and efficiently ignited, resulting in a high velocity flame jet/torch emerging from the prechamber into the main chamber. The PCC may be threaded with a 22 mm×1.5 or ??-18 thread size, to allow the PCC to be screwed into a cylinder head in place of a spark plug.

  • Patent number: 10197002
    Abstract: An engine includes a fuel injector. The fuel injector includes a valve body and an electromagnetic part that moves by energizing the valve body from a valve-closed position to a valve-open position. The fuel injector injects fuel when the valve body is moved to the valve-open position. In fuel injection, an ECU feeds a pre-charge current smaller than a current for operating the valve body, to the electromagnetic part in a pre-charge period at the beginning of a start of energization, and subsequently feeds a drive current for operating the valve body, to the electromagnetic part. Further, the ECU acquires a current change parameter as a parameter correlated with a speed of a rising change in drive current, and controls the feed of the pre-charge current to the electromagnetic part of the fuel injector, based on the acquired current change parameter.

  • Patent number: 10197037
    Abstract: The invention, while reducing noise, suppresses a load increase in a processor and a delay in drive control. An engine control unit includes a processor, a driving circuit including a switching element to drive a load such as a fuel injector and an ignition device, and a communication circuit that transmits control signals from the processor to the driving circuit via serial communication. The control signals each include a command frame for controlling the driving circuit and a data frame for driving the load. If a predetermined bits in each of the data frames received from the processor at predetermined time intervals are determined to be the same twice in succession, the engine control unit changes a state of a driving signal ‘Drive’ for driving the load and thereby changes an operating state of the switching element.

  • Patent number: 10190525
    Abstract: A method of calculating an angular position of a crankshaft at the occurrence of a fuel injection event includes integrating a first polynomial function, and integrating a second polynomial function. The integrated second polynomial function is then divided by the integrated first polynomial function to calculate the angular position of the crankshaft at the occurrence of the fuel injection event. The calculated angular position of the crankshaft at the occurrence of the fuel injection event may then be correlated to an absolute angular position of the crankshaft, relative to a Top Dead Center position of the crankshaft. The calculated angular position of the crankshaft at the occurrence of the fuel injection event may be used to adjust the injection timing of future fuel injection events.

  • Patent number: 10174703
    Abstract: Disclosed is a homogeneous charge compression ignition and diffusion compression ignition combined ignition control method for low-octane gasoline, using a diffusion compression ignition control mode as a forced ignition measure, to ignite a premixed homogeneous lean oil and gas mixture, and meanwhile to achieve homogeneous charge compression ignition of the oil and gas mixture. During an intake stroke, a fuel is partially injected into the cylinder or an intake manifold, to form a low-concentrated, homogeneous, premixed oil and gas mixture. Before the piston reaches a top dead center during the compression stroke, the remaining part of fuel is injected into the cylinder, diffuses in the air, and spontaneously ignites, thus achieving diffusion compression ignition. A flame is generated in the diffusion compression ignition, and ignites the premixed oil and gas mixture in the cylinder, to achieve ignition and combustion of the homogeneous lean fuel.
