  • Internal combustion engine
    Patent number: 9518482
    Abstract: This invention presents a method to improve the volumetric efficiency of a reciprocating internal combustion engine using a common transfer port between the exhaust and intake port. The engine employs a poppet valve as part of the intake and exhaust valve to control the flow from the transfer port into the combustion chamber. Two plate type valves outside of the combustion chamber are located at both ends of the transfer port to control the flow coming from the intake and out the exhaust. The timing for opening and closing of the poppet type valve is regulated to remain open for a longer duration which provides complete evacuation of air in the exhaust stroke. The ejector effect from the exhaust flow through the transfer port draws a vacuum into the cylinder. When the exhaust plate closes, the vacuum diverts the intake into the cylinder.

  • Preignition restraining device
    Patent number: 9500142
    Abstract: An ECU has an output-value obtaining portion, a preignition estimating portion and a valve-opening-time controller. The output-value obtaining portion obtains the output value of the knock sensor, which corresponds to an intensity of an engine knocking. A preignition estimating portion estimates that a preignition will be generated in an internal combustion engine, when the obtained output value is greater than or equal to the specified threshold. When the preignition estimating portion estimates that a preignition will be generated, the exhaust-valve timing control mechanism advances the opening time of the exhaust valve to suppress the preignition.
