Abstract: A marine propulsion system for a marine vessel includes an engine effectuating rotation of an output shaft, multiple batteries configured to power a marine vessel load, and an alternator having a rotor that is driven into rotation by the output shaft and that outputs a charge current to the batteries. The marine propulsion system further includes a control system configured to operate the engine in a propulsion mode and a generator mode. Upon receiving a generator mode command to start the engine in the generator mode, the control system operates the engine in accordance with a set of generator parameters to charge the batteries while a shift system of the marine propulsion system is locked in a neutral position such that the propulsor cannot be engaged and the marine vessel remains stationary.

Abstract: In a fuel level control system for an internal combustion engine, more than one filter having different characteristics is applied to correct the fuel level value according to the condition of the vehicle, providing precise fuel level measurement. The fuel level control system for the engine includes a fuel level correction section in which fuel level detection is prevented until a first set time has elapsed from activation of an ignition switch. The fuel level is detected by the fuel level detector after the first set time has elapsed and the detected fuel level value is corrected with a weak filter of high followability. After a second set time has elapsed the detected fuel level value is corrected with a strong filter of low followability. The strong filter minimizes the effect of disturbances on the fuel level value.

Abstract: An engine control system for an internal combustion engine of a type having a stratified combustion mode and a homogeneous combustion mode comprises a controller for controlling an EGR flow in the engine with an EGR control valve. The controller effects a changeover of an EGR control mode of the EGR control valve from a first EGR mode to a second EGR mode immediately in response to a changeover request signal before an actual changeover of a combustion control mode from the stratified combustion mode to the homogeneous combustion mode. In the case of a changeover from the homogeneous mode to the stratified mode, the controller effects a changeover of the EGR control mode from the second EGR mode to the first EGR mode in response to an actual changeover of the combustion control mode, with a delay after the changeover request signal.

Abstract: A fuel injection system for engines for improving performance and fuel economy. The fuel injector controlled along with an exhaust port timing control mechanism so that fuel injected into the engine will not pass out of the exhaust port under most engine running conditions. The invention is disclosed particularly in conjunction with a two cycle crankcase compression engine wherein it has particular utility. The timing of the opening and closing of the exhaust port is changed by means of an exhaust control valve that obstructs the exhaust port under certain running conditions so as to delay its opening and closing.

Abstract: A controller for an internal combustion engine includes processing circuitry configured to execute: a dither control process of operating fuel injection valves to designate at least one of cylinders as a lean combustion cylinder, in which an air-fuel ratio is leaner than a stoichiometric air-fuel ratio, and to designate at least another one of the cylinders as a rich combustion cylinder, in which an air-fuel ratio is richer than the stoichiometric air-fuel ratio; and an idle-time limiting process of causing an absolute value of a difference between the air-fuel ratio in the lean combustion cylinder and the air-fuel ratio in the rich combustion cylinder to be smaller when the internal combustion engine is idling than when the internal combustion engine is not idling.

Abstract: A fuel passage structure of a fuel supply device is configured to supply fuel from a fuel tank to an internal combustion engine. The fuel passage structure includes a passage-forming member that forms a fuel passage and a check valve. The fuel passage includes a vertical passage extending in a vertical direction and a lateral passage extending in a horizontal direction. The check valve is disposed at an intersection of the vertical passage and the lateral passage. The check valve includes a valve body configured to close under its own weight. The valve body is movably arranged within the vertical passage in the vertical direction. The check valve is provided with a restriction member which restricts movement of the valve body into the lateral passage, while at the same time the restriction member does not disturb the forward flow of the pressurized fuel.
