  • Patent number: 10519877
    Abstract: A control system for a dual fuel engine having a liquid fuel supply and a gaseous fuel supply is disclosed. The control system may include at least one sensor operably coupled to a cylinder of the dual fuel engine and configured to monitor cylinder condition and transmit a cylinder condition signal. Additionally, a controller may be communicably coupled with the at least one sensor and the controller may be configured to receive the cylinder condition signal and determine whether the cylinder is operating in an abnormal operating condition. Whereas the controller determines the cylinder is operating in the abnormal operating condition, the controller sends a control signal for the liquid fuel supply to provide an amount of liquid fuel which is greater than an amount of liquid fuel supplied to the cylinder during a normal operating condition.

  • Patent number: 10508603
    Abstract: An apparatus for controlling an internal combustion engine is provided. An engine includes a compression release mechanism and a fuel injection valve. The compression release mechanism variably controls the opening degree of a valve member, and thereby connects the combustion chamber of the engine with at least one of the intake passage and the exhaust passage in order to release in-cylinder pressure during at least the compression stroke. A controller controls the fuel injection valve to execute coasting with the fuel cut off in which the fuel is cut off under a predetermined condition, and while executing coasting with the fuel cut off, controls the compression release mechanism to increase the opening degree of the valve member of the compression release mechanism as the speed of the engine is higher.

  • Patent number: 10508611
    Abstract: The present invention relates to a control device and a control method for an internal combustion engine including a fuel injection valve and an electric fuel pump. In stopping the internal combustion engine, the control device stops driving of the fuel pump and then fuel injection by the fuel injection valve, and increases the total amount of fuel injection by the fuel injection valve after stopping of driving of the fuel pump as the temperature of fuel in stopping the internal combustion engine decreases, thereby reducing a fuel pressure in a stop period. In this manner, fuel leakage from the fuel injection valve in the stop period can be reduced with a simple configuration.
