摘要： An injection timing for supplying a fuel by one injection per two rotations to a single-cylinder four-cycle engine of a fixed spark advance ignition system is decided on the basis of a simple system. With respect to ignition signals A1, B1, A2, B2, generated every one rotation of the engine, an intake pipe pressure lowering state exists in one ignition signal cycle A1-B2, and the intake pipe pressure lowering state does not exist in the next ignition signal cycle B2-A2. The signal B1 corresponds to a terminal phase of an exhaust stroke and the signal A2 corresponds to a terminal phase of a compression stroke if these two conditions are established, and an injection timing is decided on the basis of the determination in such a manner that the fuel injection burnt by the ignition of A2 is executed at one time during two rotations.

摘要： An electronic control method for a throttle by an electronic control throttle device that controls the throttle while an electronic control unit generates a control signal based on an input data signal. The method may include calculating an engine rotation speed deviation from a difference between an engine rotation speed and an input engine rotation speed command, calculating an engine rotational acceleration based on the engine rotation speed, obtaining a proportional torque from a product of the engine rotation speed deviation and a predetermined coefficient, obtaining an integral torque by integrating a value obtained by subtracting a product of the engine rotational acceleration and the predetermined coefficient from the product of the engine rotation speed deviation and the predetermined coefficient, and generating a control signal for the throttle by using a sum of the proportional torque and the integral torque as a value of a torque command.

摘要： A method for controlling fuel injection to an engine may include calculating an amount of air passing through a throttle, which is actually controlled, from a calculated amount of air in an intake manifold, which is calculated from a pressure value detected by a pressure sensor installed in the intake manifold connecting the throttle and a cylinder to each other, and a calculated pressure change in the intake manifold. The method may further include predicting an actual amount of air to be sucked into the cylinder when mixed with fuel from the calculated amount of air in the intake manifold and the calculated amount of air passing through the throttle. The method may also include injecting an amount of fuel according to the predicted actual amount of air to be sucked into the cylinder.

摘要： In an electronically controlled throttle control device in which a throttle control output command calculated by an electronic control unit (ECU) is calculated based on a throttle main control command, calculated from a throttle opening deviation which is a difference between a throttle opening command and a throttle opening detection signal, and a throttle correction control command which is a value obtained by integrating a product of the throttle opening deviation and a coefficient, the coefficient for calculation of the throttle correction control command is changed depending on a driving state based on an acceleration state and a deceleration state of a throttle and a small throttle deviation state.

摘要： Provided is a fuel pressure monitoring system of a vaporizer using a safety module which issues a fault signal by detecting a pressure using a fuel pressure sensor disposed in a pressure regulating chamber of the vaporizer within a predetermined time after an engine is stopped and determining that the pressure regulating mechanism fails when the detected pressure exceeds a threshold stored in a storage device to be increased to a predetermined pressure or higher, and the pressure regulating mechanism is determined to fail only when a water temperature of cooling water in the engine of the vaporizer reaches a predetermined temperature at which warming up of the engine can be determined to be completed.

摘要： A fuel supply system includes a housing including a housing body in which a fuel storage tank serving as a reservoir tank as well and a lid covering an opening of the housing body in an air-tight manner. The housing includes a fuel pump, a regulator configured to regulate a pressure of the fuel to return excess fuel to the fuel storage tank, a regulator holding member supporting the regulator, and a fuel storage volume adjusting unit that maintains the liquid surface level of the stored fuel at a fixed level. The fuel supply system supplies fuel at a predetermined pressure from a fuel discharging pipe of the lid to the engine. The regulator holding member is formed in such a manner in a planar view as to fill most of interspace in the opening of the housing body to close the upper portion of the fuel storage tank.
