    摘要： Apparatus and method for determining vehicular distance per fuel unit, such as the miles per gallon or liter of fuel consumed in driving a car. The vehicle has a fuel gage, and when stopped on, or operating on level road, a reference mark is made where the fuel gage pointer is then located and the odometer mileage reading is recorded. Vehicle operation is continued and when convenient, fuel is then added to the fuel tank to cause the pointer to show a greater quantity of fuel in the tank than is shown by the reference mark. The vehicle is then driven until the fuel gage pointer again returns to the reference mark, and the total distance traversed is also determined. With the knowledge of the amount of fuel consumed and the total distance traversed, the distance traversed per unit of fuel can be calculated. The reference mark is preferably established by means of a sight device which permits the operator to accurately locate the reference mark in alignment with the fuel gage pointer, and visual assists are available in the sight device for the accurate alignment mentioned.

    摘要翻译： 用于确定每个燃料单元的车辆距离的装置和方法，例如在驾驶汽车时消耗的每加仑英里/升燃油。 车辆具有燃料计量器，当停在或在水平道路上操作时，在燃料计量指示器然后被定位并且记录里程表里程读数时，作出参考标记。 车辆操作继续进行，当方便时，将燃料添加到燃料箱中，使得指示器在罐中显示比参考标记所示更大量的燃料。 然后驱动车辆，直到燃料计量指针再次返回到参考标记，并且还确定所经过的总距离。 通过了解燃料消耗量和总距离，可以计算每单位燃料所穿过的距离。 参考标记优选通过瞄准装置建立，其允许操作者精确地定位与燃料计量指示器对准的参考标记，并且在瞄准装置中可以获得视觉辅助以便所提到的精确对准。
