摘要： An electronically controlled regulator is disclosed. The electronically controlled regulator reduces and adjusts a pressure of a high-pressure fluid introduced through an introduction port with a pressure adjusting valve and discharges a pressure-reduced fluid having a set pressure through a discharge port. A discharge pressure adjusting mechanism includes a valve shaft moving structure that operates by driving of an electric motor and moves a valve shaft to change a distance between a valve body and a valve seat, and opens and closes the pressure adjusting valve so that the pressure of the pressure-reduced fluid maintains the set pressure while operating the valve shaft moving structure with the electric motor on the basis of a value of a pressure sensor that detects the pressure of the pressure-reduced fluid.

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 fuel supply device may include a housing including a housing body and a lid. The housing body may form a fuel storage tank. A fuel pump, a regulator, and a fuel storage amount adjusting unit may be disposed in the housing. The lid may have an excess fuel discharge path through which excess fuel flowing down from the regulator is fed to an inner wall side of the housing body. The housing body may have an upward fuel receiving surface that receives the excess fuel discharged at a lower position on an end side of the excess fuel discharge path. The fuel receiving surface may be structured and arranged such that the excess fuel discharged through the excess fuel discharge path is temporarily received by the fuel receiving surface and then returned to the fuel storage tank along an inner wall surface of the housing body.

摘要： Even if the engine structure is not capable of continuous operation in the vicinity of stoichiometric air-fuel ratio, this engine is in the stoichiometric combustion region when condition such as low load and stable engine rotation is met, and the feedback control using the O2 sensor, although temporary, becomes possible. Therefore, the air-fuel ratio control system performs this feedback, and derives and sets the constant value for correction to attain the air-fuel ratio suited to the engine. Thereafter, the optimal air-fuel ratio is controlled at the normal control mode just by correcting the fuel injection quantity using the constant value.
