Abstract: PURPOSE: A compressor fin is provided to reduce material cost while maintaining superior cooling efficiency by arranging fins arranged onto a condenser to have different fin pitches so as to correspond to a change of the amount of air from an axial blower. CONSTITUTION: In a condenser(200) mounted to an indoor unit of an air conditioner and which is cooled by heat-exchange with an air flowing by a rotation of an axial blower(210), a plurality of compressor fins with a first pitch(i.e., spacing between each of the fins) are arranged in a portion facing a radial outside of the axial blower, and a plurality of fins with a second pitch are arranged in a portion facing the center portion of the axial blower. The fins are arranged in such a manner that the first pitch is narrower than the second pitch. Thus, fins arranged at the center portion of the condenser have wider pitches, thereby reducing material cost.

Abstract: PURPOSE: A method for controlling the fuel injecting time of a diesel vehicle is provided to operate an engine within an injecting time considering durability even in any operation conditions. CONSTITUTION: An engine electronic control unit(20) advance-controls an injecting time to compensate the engine performance at a low temperature. Herein, the advance-control is performed by calibrating a basic injecting time according to an engine cooling water temperature and an absorbed air temperature. A map data is obtained by mapping the injecting time by the maximum advance amount within an engine durability limitation based on the rotation number of an engine and a fuel amount. The engine electronic control unit decides the maximum advance value of the injecting time by the map data. Then, a smaller value is decided as the final fuel injecting time by comparing the maximum advance value of the injecting time decided by the engine rotation number and fuel amount with the calibration value of the injecting time.
