What Does Instantaneous Fuel Consumption Mean?

[DelaneyDella]

Instantaneous fuel consumption refers to the fuel consumption of a vehicle at a specific moment, reflecting the transient operating condition of the car. When the vehicle is in motion, the displayed unit is "liters per 100 kilometers (L/100Km)." However, if the engine is running but the vehicle is stationary, the unit displayed is "liters per hour (L/H)." Below is an introduction to instantaneous fuel consumption: 1. High instantaneous fuel consumption does not necessarily mean high average fuel consumption. Since modern fuel-injected engines can cut off fuel supply during coasting, some models may show a minimum instantaneous fuel consumption of 0. 2. When climbing a steep slope, the throttle may be pressed deeply, but the speed remains low, which naturally results in high instantaneous fuel consumption. 3. During acceleration from a standstill, the engine needs to exert significant force to change the vehicle's state. Therefore, it is normal for the instantaneous fuel consumption displayed on the dashboard to reach 40 or even higher during acceleration or uphill driving.
