摘要： A control apparatus for an AC rotating machine that can reliably and stably start up an AC rotating machine, particularly a synchronous motor using a permanent magnet, in position-sensorless vector control thereof, includes: a steady speed calculator that calculates, during steady state control of the AC rotating machine, a rotation angular frequency of the AC rotating machine based on an AC current and voltage commands; and a start-up speed calculator that calculates, during start-up control within a predetermined period after the AC rotating machine has been started up, the rotation angular frequency of the AC rotating machine based on the AC current and the voltage commands. The control apparatus corrects during the start-up control current commands so that the AC voltage amplitude of the voltage commands will be a constant value not more than the maximum output voltage of a power converter.

摘要： A resistance calculation activator determines whether or not an electric car is stopped on the basis of a drive command signal and an external signal, and activates a resistance calculator if a powering command is input as the drive command when it is determined that the electric car is stopped. The activated resistance calculator computes, within a resistance calculation period, a resistance value of an AC motor that produces driving force for the electric car, on the basis of a d-axis voltage command value and a d-axis current value supplied to the AC motor.

摘要： A NOx selective reduction catalyst for reducing NOx by the ammonia adsorbed is disposed in an engine exhaust gas passage. As states of adsorption of ammonia by the catalyst, there are a first adsorption state of ammonia that occurs when the ammonia is adsorbed during low temperature and a second adsorption state of ammonia that occurs when the ammonia is adsorbed or has already been adsorbed during high temperature. The amount of adsorbed ammonia in the first state is restricted to control concentration of the ammonia that is in the first state and desorbed when the temperature of the catalyst increases so as to be not higher than an allowable concentration, and that in the second state is restricted to control concentration of the ammonia that is in the second state and desorbed when the temperature of the catalyst increases so as to be not higher than an allowable concentration.

摘要： A combustion chamber side end portion of a fuel injection valve is placed at a location that overlaps with an imaginary plane, which is perpendicular to a center axis of a cylinder and extends along a portion of a wall surface of an intake port where an intake valve protrudes, or is projected out from the imaginary plane toward a combustion chamber. Alternatively, a center of a fuel injecting side end port of the fuel injection valve, which injects fuel into intake air that flows in a branch port branched from the intake port, may be placed on the center axis side of the intake valve in a radial direction of the cylinder. Further alternatively, an upstream side fuel injection valve may inject fuel into intake air that flows in the intake port, and a downstream side fuel injection valve may inject fuel into intake air that flows in the branch port branched from the intake port. Alternatively, an injection quantity of fuel may be controlled for each of fuel injection valves, which injects fuel into intake air that flows in the corresponding branch port branched from the intake port.
