ABSTRACT:
A fuel consumption measuring device is provided with a flow meter which is mounted on a fuel feeding passage extending from a fuel tank to an engine, wherein a return fuel which is not consumed by the engine is returned to a passage in the downstream of the flow meter through a return passage so as to measure a fuel consumption in the engine by the flow meter. The fuel feeding passage is provided with a pressure reducing valve for maintaining a confluence of the fuel feeding passage and the return passage at atmospheric pressure. Therefore, the fuel consumption measuring device has high measuring accuracy and high security, and is suitable for a vehicle.
