  • Patent number: 6846212
    Abstract: In fuel supply system for an engine in which a discharge port in a fuel pump driven by the engine to draw up fuel in a fuel tank is connected to an inlet port which is provided in a fuel reservoir and which is controlled in opening and closing by a float valve so that the fuel in the fuel reservoir is supplied to the engine, a second discharge port is provided in the fuel pump, and a second inlet port without a float valve is provided in the fuel reservoir. The second discharge port and the second inlet port are connected to each other through a control valve opened during starting of the engine. Thus, when the engine is started, fuel vapor generated in a pump chamber in the fuel pump can be discharged to the fuel reservoir having an air vent, to normalize the function of the fuel pump, leading to an enhancement in hot startability of the engine.

  • Patent number: 6820470
    Abstract: A system detecting leakage of an internal combustion engine having a secondary air passage, bypassing a throttle valve, at an air intake pipe connecting to the intake manifold and a secondary air control valve which regulates opening of the secondary air passage. In the system, when the changes in the absolute manifold pressure and the atmospheric pressure before and after the engine starts rotation, are small, it is determined that the intake manifold may possibly leak and should be monitored. Specifically, the opening of the secondary air passage is changed and the changes in the pressure, etc., before and after the opening is changed, are calculated and based thereon, it is determined whether the intake manifold, in fact, leaks. With this, it becomes possible to detect intake manifold leakage accurately with a simple configuration.

  • Patent number: 6810724
    Abstract: A system for detecting reverse rotation of a 4-cycle, internal combustion engine with three or more cylinder for an outboard motor mounted on a boat, whose output is connected to a propeller such that the boat is propelled forward or reverse. In the system, it is determined whether a counted value of crank angle signals generated once every 30 crank angles is a multiple of a predetermined number (e.g., four in six cylinders), when the cylinders are identified and it is determined that engine rotates reverse when the counted value is determined to be not the multiple and the engine is immediately stopped. With this, it becomes possible to accurately detect the reverse rotation of the engine and prevent its further reverse rotation.

  • Patent number: 6792797
    Abstract: A system for detecting malfunction of an equipment such as an alternator or a hydraulic switch that is connected to an internal combustion engine and generates an output. In the system, it is discriminated periodically for a predetermined period of time whether the output of the equipment is within a predetermined range, a number of times that the output of the equipment is discriminated to be out of the predetermined range is counted; and the equipment is determined to have malfunctioned when the count is equal to or greater than the reference value. With this, it becomes possible to detect the malfunction of the equipment accurately.

  • Patent number: 6778076
    Abstract: An oil pressure switch failure detection system for an outboard motor, having a first oil pressure switch which generates an ON signal indicating that the oil pressure is less than or equal to a first predetermined oil pressure and a second oil pressure switch which generates an ON signal indicating that the oil pressure is less than or equal to a second predetermined oil pressure which is set higher than the first predetermined oil pressure. In the system, by discriminating whether the generated signals of the first and second oil pressure switches are equal to be expected signals expected under operating conditions of the engine, it is determined whether at least one of the first and second oil pressure switches fails. With this, it become possible to detect failure of the first and second oil pressure switches, accurately.

  • Patent number: 6685515
    Abstract: A system for detecting overheat of an internal combustion engine for an outboard motor. In the system,when an elapsed time since engine staring is within a predetermined time, a detected engine temperature is equal to or greater than a first predetermined temperature and an detected engine speed exceeds an idling speed; a threshold value (compared with the detected engine temperature to determine the engine overheating) is changed to be increased. With this, even if the detected engine temperature is higher than a true or actual temperature at, for example, a high engine load immediately after engine starting or when the engine has been left in the idling state, the system can prevent it from being determined unnecessarily as the overheated condition.

  • Patent number: 6612882
    Abstract: An idling speed control system for an outboard motor mounted on a boat and equipped with an internal combustion engine, whose output is connected to a propeller through a clutch, having secondary air supplier that supplies secondary air. In the system, a difference of preceding and present current command values each indicative of a desired secondary air supply amount is comparing with a predetermined value when the clutch is changed, and the current command value is increased or decreased by a predetermined correction amount when the difference is greater than the predetermined value. With this, it can surely improve the control stability and suppress the overshooting or undershooting of engine speed due to the load change when the clutch is changed, thereby enabling to eliminate or reducing the shock to be felt by the operator and improving the feeling of the operator.

  • Patent number: 6614345
    Abstract: An oil pressure warning system for an outboard motor for detecting and alarming an abnormal oil pressure of an internal combustion engine, the system including a first oil pressure switch which generates an ON signal when the oil pressure is less than or equal to a first predetermined oil pressure, and a second oil pressure switch which generates an ON signal the oil pressure is less than or equal to a second predetermined oil pressure set higher than the first predetermined oil pressure. The abnormality of oil pressure is detected and alarmed based on the ON signal of the switches. The first and second predetermined oil pressures are determined based on an oil pressure characteristic of a (possible) maximum oil temperature (under which the engine has been warmed up) set relative to the engine speed, thereby ensuring to detect and alarm the abnormality of oil pressure under any engine speed and any oil temperature.

  • Patent number: 6599158
    Abstract: An idling speed control system for an outboard motor mounted on a boat and equipped with an internal combustion engine, whose output is connected to a propeller through a clutch, having secondary air supplier that supplies secondary air. In the system, the engine start-state as to whether the engine has been started is determined and the clutch position is detected and based thereon, the desired idling speed and the desired secondary air supply amount is determined through learning control. With this, the system can therefore accurately determine the desired idling speed and the desired secondary air supply amount and achieve steady idling speed even if load changes owing to a change in clutch position or propeller replacement.
