摘要： Engine-starting enrichment is decreased gradually, after the engine is completely started, in response to the temperature difference between the present-coolant temperature and the initial-coolant temperature. The initial-coolant temperature is determined to be equal to the present-coolant temperature just when the engine is completely started.

摘要： An engine comprising a main intake passage having a throttle valve therein. A bypass passage is branched off from the main intake passage located upstream of the throttle valve and is connected to the main intake passage located downstream of the throttle valve. A flow control valve, actuated by a step motor, is arranged in the bypass passage. When the engine is operating in an idling state, the step motor is rotated in a rotating direction wherein the engine speed approaches a desired idling speed. An air conditioning device is provided, which comprises an air duct, an evaporator arranged in the air duct, a heat exchanger arranged in the air duct, and an air mixture damper for controlling the flow of air which has passed through the evaporator. The desired engine speed is increased when the temperature of air, which has passed through the evaporator, becomes higher than a predetermined temperature and when the entire air, which has passed through the evaporator, directly flows into the driver's compartment without passing through the evaporator.

摘要： There is provided a radar apparatus for detecting a target. A detection signal generating unit generates detection signals of the target based on transmission and reception waves of antennas. A detection signal processing unit performs frequency analysis on the detection signals to extract signal components of the target, and performs a predetermined process on the signal components to calculate at least one of a distance to the target, a relative speed to the target, and an orientation of the target. The detection signal generating unit includes a filter unit for giving changes to the detection signals in a frequency bandwidth higher than Nyquist frequency which is a half a sampling frequency. The detection signal processing unit acquires the signal components from the detection signals to which the filter unit gives the changes to determine whether the signal components are generated by replication due to the Nyquist frequency.
