Abstract: An electrically operated power steering apparatus in a motor vehicle has a steering system for steering the motor vehicle, a steering torque detector for detecting a manual steering torque applied to the steering system, and an electric motor for generating an assistive torque to be transmitted as a steering assistive force to the steering system. An actual assistive torque detector detects an actual assistive steering torque which is actually transmitted from the electric motor to the steering system. A controller has at least a target assistive torque generator for generating a target value for an assistive torque to be generated by the electric motor depending on the manual steering torque detected by the steering torque detector, and generates a control signal based on the difference between the actual assistive steering torque detected by the actual assistive torque detector and the target value generated by the target assistive torque generator.

Abstract: An emulsion oil containing oil and water in a ratio of 5 - 9.5:5 - 0.5 by volume is burned by two-stage combustion method or by the combination of two-stage combustion method and exhaust gas recirculation method.

Abstract: In burning an emulsion oil containing oil and water in a ratio of 5 - 9 : 5 - 1 by volume, a method characterized in that the emulsion oil is burned while recycling 10 to 40% by volume of the resulting combustion exhaust gas to a combustion chamber.
