Abstract: An apparatus for supplying dimethylether common rail fuel enables a high pressure pump (23) to supply dimethylether fuel to multiple injectors (30) through a common rail (24) and sprays the dimethylether fuel to a cylinder; collects the fuel remaining in the injector after the spraying, to a return gallery (31) formed to connect the multiple injectors to the cylinder head, then returns the fuel to a fuel tank (10). An auxiliary pump (70) is also installed on a bypass line (B) which bypasses the high pressure pump (23) and the common rail (24) then is joined to the return gallery (31). An ECU(60) determines the types of the dimethylether fuel returned by the injector. If the fuel is liquid, the ECU operates only the high pressure pump. If the fuel is gas or has possibility of being gasified, the ECU operates the auxiliary pump additionally.

The common rail maintains the pressure generated by the fuel pump and transfers the pressure to each injector. The injector comprises a bypass line(B) in an upper stream. The fuel amount control valve is installed in the bypass line and directly controls the fuel from the fuel pump along the bypass line with the injector.

Abstract: PURPOSE: Logic for checking whether or not the performance of an air volume sensor decreases and a diagnostic method thereof are provided to prevent damages to vehicles and engines by informing drivers with a time to replace the air volume sensor. CONSTITUTION: Logic for checking whether or not the performance of an air volume sensor decreases measures the air volume sucked into an engine using an air volume sensor if an ignition switch is turned on. The logic comprises an engine controller. The engine controller determines that the performance of the air volume sensor decreases if measured air volume is smaller than standard air volume(S6). The engine controller determines whether or not battery voltages, the amount of fuels, engine RPM, and water temperature are satisfied for a condition to check the performance of the air volume sensor if the ignition switch is turned on. If the condition is satisfied, whether the performance of the air volume sensor decreases or not is determined.

Abstract: 본 발명은 차량의 연비 극대화를 위한 멀티토크 및 듀얼파워 혼용 시스템에 관한 것으로,
종래에는 차량의 연비저감을 목적으로 멀티토크 로직과 오르막길 출력 강화를 목적으로 하는 스마트파워 로직을 동시 적용하였지만 실제 연비 개선 효과가 미미하게 되는 문제가 있었고, 아울러 급출발 및 급가속시에 운전감이 떨어지게 되고, 평지 운전시 출력이 부족하게 되며, 고속 주행시 최고 속도에 대한 불만이 있게 되는 등의 문제가 있었던 바,
엔진 공칭토크 범위내에서 변속기(TM) 기어 단수별로 최대 토크를 별도 설정하는 멀티토크와; 엔진 전영역에서 공칭출력의 70~90% 범위내의 출력인 연비출력으로 운전함으로써 변속기(TM) 단수별 최대(MAX) 출력을 제한하여 차량의 부하 조건에 따라 잉여 출력에 소비되는 연료량을 제한하는 듀얼파워;를 통해 엔진 토크 및 출력을 선택 제어하는 것을 특징으로 하는 본 발명의 차량의 연비 극대화를 위한 멀티토크 및 듀얼파워 혼용 시스템에 의하면 듀얼파워 및 멀티 토크를 적절히 분배하여 부하운전 구간 및 고지대구간 등에 관계없이 연비를 최적화하고 파워 운전을 할 수 있게 되므로 차량의 성능을 크게 향상시킬 수 있게 되고, 연비를 2.2% 이상 절감할 수 있게 되므로 차량의 상품성을 크게 향상시킬 수 있게 되는 등의 효과를 얻을 수 있게 된다.
