摘要： A supercharging device for an engine is provided, which includes a supercharger to be provided to an intake passage of the engine, an actuator configured to drive the supercharger, and a controller including a processor configured to control the actuator to drive the supercharger when an operating state of the engine is in a given supercharging range, and to stop or drive the supercharger when the operating state is in a non-supercharging range. The controller estimates an amount of condensate accumulated in an oil pan, and the controller causes the actuator to forcibly drive the supercharger when the estimated amount of condensate is equal to or more than a preset amount, even if the operating state is in the non-supercharging range.

摘要： A supercharger constructed in accordance to one example of the present disclosure can include a first shaft portion, a coupling assembly, a clutch rotor and a clutch armature. The first shaft portion can be connected to a pulley. The coupling assembly can couple the first shaft portion to a second shaft portion. The first and second shaft portions can be configured to rotate around a common longitudinal axis. The coupling assembly can be configured to provide torsional damping between the first and second shaft portions. The clutch rotor can be mounted to the second shaft portion. The clutch armature can be mounted to a drive shaft and be unconnected to the first and second shaft portion. The clutch rotor and the clutch armature can selectively cooperate in an engaged position and a disengaged position. In the engaged position, the clutch rotor and the clutch armature rotate together.

摘要： A power system including a stoichiometric compression ignition engine (10) in which a roots blower is positioned in the air intake (12) for the engine (10) to control air flow. Air flow is decreased during part power conditions to maintain the a ir-fuel ratio in the combustion chamber of the engine (10) at stoichiometric, thus enabling the use of inexpensive three-way catalyst to reduce oxides of nitrogen. The roots blower is connected to a motor generator (34) so that when air flow is reduced, electrical energy is stored which is made available either to the roots blower to temporarily increase air flow or to the system electrical load (40) and thus recapture energy that would otherwise be lost in reducing air flow.

摘要： An internal combustion engine provided with a mechanically operated supercharger in kinematic connection with a crankshaft the engine. The engine is provided with a system for controlling the effect of supercharging, such as a by-pass control valve. A timer is provided for detecting a predetermined short period after the engine is switched to an acceleration condition from the preceding deceleration condition with a fuel-cut, or after a moderate acceleration has begun. The system for controlling the effect of the supercharging is so controlled that the effect of supercharging is weakened during that period.

摘要： An improved supercharger or blower (10) of the Roots-type with reduced airborne noise and improved efficiency. The blower includes a housing (12) defining generally cylindrical chambers (32, 34) containing meshed lobed rotors (14, 16) having the lobes (14a, 14b, 14c, 16a, 16b, 16c) thereon formed with an end-to-end helical twist according to the relation 360 * /2n, where n equals the number of lobes per rotor. In one embodiment, blower housing (12) also defines inlet and outlet ports (36, 38). The inlet port includes longitudinal boundaries defined by housing wall surfaces (20f, 20h) and transverse boundaries defined by housing wall surfaces (20g, 20i). The transverse boundaries (20g, 20i) are disposed substantially parallel to the helical lobes. The outlet port includes longitudinal boundaries defined by housing surfaces (20m. 20r) and a transverse boundaries defined by housing surfaces (20p, 20s). The inlet and outlet port openings are skewed in opposite directions to increase the time top lands of the lobes are in sealing relation with cylindrical walls (20a, 20b) of chambers (32, 34). Expanding orifices (42. 44) defined by the intersection of transverse boundaries (20p, 20s) and longitudinal boundary (20m) are disposed substantially midway between ends (14g, 14h and 16g, 16h) of the lobe lands to reduce backflow noise.
