When it comes to fuel consumption, we need to know how much fuel is consumed by a hundred kilometers of this car, or how much oil it costs for a kilometer. However, for many new car drivers, they always do not understand how to calculate a car. The basic fuel consumption. In fact, there are many fuel consumption calculation methods. Different people use different calculation methods, which will lead to greater errors in the calculated results. Therefore, for the calculation method of automobile fuel consumption, let's analyze how the automobile fuel consumption is calculated.
The more accurate formula for calculating the fuel consumption of a car is:
Consumption of fuel/range = Fuel consumption per kilometer.
For example, the capacity of our engineering vehicle's tank is 50 litres. When there is still 10 litres of oil, the oil meter light will be on. At this time, we have already run 500 kilometers so that we can calculate our fuel consumption per kilometer. That is, 40 liters/500 km = 0.08 liters/km. The fuel consumption per 100 km is 8 liters. By adding oil three times in this way, we can calculate a more accurate fuel consumption. Of course, we need to clear the odometer after each full oil, so that the number of kilometres run is accurate.
Generally speaking, the fuel consumption of driving in the city is relatively high, because the displacement of the engine is certain, and the relative speed of the car is relatively slow, because the stall in the urban area is low. If it is on the high speed, the engine speed is the same as the speed in the city (we can see the tachometer when driving, basically keep it between 1000 and 6,000 rotations), but the gear is high, the car The speed is relatively fast, so the fuel consumption is also lower at the same distance.
This is why people often say: The reasons for high-end fuel-efficient than low-grade. However, although the high-end is more fuel-efficient, it is better to upgrade or downgrade as needed. If the upshift is too early, because the engine speed after the upshift will slow down, then some oil will remain in the cylinder can not be fully burned, thus forming carbon deposits in the cylinder, which is no good for the engine. For a long time, fuel consumption will increase. As for how many rotations should be upshifted, it will vary according to different engines. Generally speaking, the displacement is large and the fuel consumption is high. This is just a general case. The exception is the piston. If the piston is slow, the fuel consumption may not be high.
For example, when some new energy vehicles run at a high speed, instead of using gasoline as a power source, electric power is reduced, and the Pistons do less work and fuel consumption will be relatively reduced. In addition to automotive fuel consumption and displacement related to the size of the car's appearance, weight and engine technology and other factors will also affect fuel consumption.
