摘要： A multi-cylinder 2 cycle engine having n cylinders has fuel injected and ignited at (n-1).times.360/n crank angle intervals. This induces the situation wherein combustions occur in each cylinder at n-1 cycle intervals. This provides at least one piston stroke for each cylinder during in which no combustion takes place and fresh air is pumped through the combustion chamber in a manner to scavenge residual combustion gases therefrom.

摘要： A hydraulic power steering system is disclosed which has a steering control valve operatively connected to a steering shaft to be actuated by the torsional torque exerted thereon by a steering wheel, and a hydraulic cylinder operated by the control valve for assisting the steering of the vehicle. An electric motor drive unit is coupled to the steering shaft for exerting torque thereto in a direction for returning the steering wheel to a straight ahead position. An electronic control circuit is connected to the motor drive unit for exerting a variable amount of return torque to the steering shaft according to the steering angle of the steering shaft, or to both the steering angle and the travelling speed of the vehicle.
