Abstract: PURPOSE: COP(catalyst overheat protection) area is decided in reference of an exhaust gas temperature and a catalyst temperature to adjust fuel amount, thereby improving air fuel ratio. CONSTITUTION: A method for deciding fuel amount feedback control comprises step of deciding whether an exhaust gas temperature is over a certain level. If the exhaust gas temperature is not over the level, it is decided as an air fuel ratio control area, and a feedback control using an oxygen sensor is carried out. If the exhaust gas temperature is over the level, it is decided as a COP area, and mapped fuel amount is injected. If the mapped fuel amount is injected, it is decided whether the exhaust gas temperature is over a certain level again. If then, fuel is more injected, and if not, the fuel is reduced.

Abstract: PURPOSE: An oil pump driving system for a vehicle engine is provided to vary the driving revolutions per minute according to the revolutions per minute of the engine, thereby improving the power performance and fuel efficiency performance of a vehicle. CONSTITUTION: An oil pump driving system for a vehicle engine includes a pump housing(10), a slider(11), a spring support(12), a relief spring(14), a spring mounting part(13), and a first and a second hydraulic chamber(211,222). The relief spring is mounted on the pump housing, and provides a restoring force to the spring support. The spring mounting part for mounting the relief spring is installed in the pump housing in response to the spring support. The first and the second hydraulic chamber are formed on the outer circumferential surface of the pump housing, and are mutually blocked and partitioned so that the slider is rotated on a pivot(P) by a hydraulic force. A connection between the first and the second hydraulic chamber is selectively opened or closed.
