Abstract: A supercharged engine includes an engine body, an electric supercharger, a turbocharger, an EGR passage establishing communication between an exhaust passage downstream from a turbine of the turbocharger and an intake passage upstream from a compressor of the turbocharger, a fuel supply unit configured to supply fuel into a cylinder, and a controller configured to open the EGR passage and output a control signal to the electric supercharger to increase a boost pressure of the electric supercharger during acceleration of the vehicle in which an amount of the fuel supplied by the fuel supply unit is increased in response to an acceleration request signal.

Abstract: Provided are a motor capable of forcibly rotating an engine when the engine is started; and an electric supercharger disposed in an intake passage and driven by electric energy. When the engine is started in a state that a temperature inside a cylinder is equal to or higher than a predetermined first reference temperature, the electric supercharger is driven after an assist motor is driven. When the engine is started in a state that a temperature inside the cylinder is lower than the first reference temperature, the assist motor is driven after the electric supercharger is driven.

Abstract: A pretensioner includes a gas generator, a pinion, a tube pipe, a piston ball, a plurality of balls, and a tube cover. The tube pipe includes a tubular part that is formed continuously from one end portion to the other end in order to receive the piston ball and the plurality of balls. A hook portion formed at the other end portion is angled toward the pinion. A tip end part of the hook portion is attached to at least one of a refractor frame and the tube cover. With this construction, a reduction in an engagement amount between the pinion and the balls during operation of the pretensioner can be prevented, and as a result, the pinion can be rotated efficiently.

Abstract: There is provided a method of controlling an engine system having an internal combustion engine, a supercharger arranged in an intake air passage of said internal combustion engine and a motor capable of driving the supercharger. The method comprises, driving the motor to operate the supercharger to boost airflow inducted into the internal combustion engine when the internal combustion engine is in operation. The method further comprises driving the motor to determine a state of the supercharger when the internal combustion engine is stopped and indicating the determined state of the supercharger. According to the method, by driving the motor of the supercharger to detect a state of the supercharger when the internal combustion engine is stopped, the state of the supercharger can be more accurately detected because the condition is most stable.

Abstract: The present invention provides a seat belt system comprising: a moving element (36) rotatably received in a housing (26); a device (32) for applying a pressurized gas to the moving element (36) when abrupt deceleration occurs on a vehicle; a tensile member (40) responsive to movement of the moving element (36) extruded due to the pressurized gas to generate a rotational torque; and a clutch mechanism (44) for transmitting the rotational torque generated by the tensile member (40) to a retractor shaft (24) to rotate the shaft (24) in a webbing-winding direction.

Abstract: A rack can transmit a rotational torque in a webbing winding and tightening direction to a take-up spindle of a retractor via a pinion gear. In the event of a vehicular collision, this rack is pushed and driven by gas pressure. To rotate at an increased speed an outer clutch ring which can intermittently transmit a torque to the take-up spindle via a clutch mechanism, a speed-increasing gear unit is arranged between the pinion gear and the outer clutch ring.

Abstract: Accommodated within a trigger casing are a firing pin arranged movably toward a detonator, an inertia body formed of a permanent magnet and defining along a central axis thereof a through-hole through which the pin extends freely, and a cylindrical permanent magnet having an inner diameter greater than an outer diameter of the body. A ring-shaped non-magnetic weight is also accommodated within the casing in such a way that the weight is arranged on a side opposite to the detonator with the body located between them. When a deceleration or acceleration of at least a predetermined value occurs, the body and the weight together move toward the detonator against magnetic repulsion between the magnet and the body. The inertia body then moves toward the detonator through an opening of a cylindrical permanent magnet under magnetic attraction between the magnet and the body, thereby causing the firing pin to move toward the detonator.

Abstract: An auxiliary mechanism mounting structure for mounting an auxiliary mechanism on an engine has an auxiliary mechanism mounting portion whose bearing rigidity is high in the longitudinal direction of the engine and is low in the vertical direction of the engine so that the auxiliary mechanism is easy to vibrate in the vertical direction of the engine.
