What does NEDC combined fuel consumption mean?
1 Answers
NEDC combined fuel consumption stands for New European Driving Cycle, which is a method used in Europe to test vehicle energy consumption. The following factors affect combined fuel consumption: Thermal efficiency of the engine: From a purely technical perspective, direct injection is an excellent technology that significantly improves fuel combustion efficiency, but it imposes higher requirements on the engine's fuel supply system and cylinder materials. Gradient resistance: When a car is driving on a sloping road, the component of its gravity along the road direction manifests as gradient resistance. Clearly, it is mainly related to the vehicle's weight. The heavier the car and the steeper the slope, the greater the force required to overcome, resulting in higher fuel consumption.
