1. 100 km fuel consumption = volume (liter) of a certain amount of fuel ÷ the distance that a car can travel under this amount of fuel (km) × 100 km fuel consumption is an indicator of a vehicle. When calculating fuel consumption on expressways and engineering transportation, the first two specifications are not applicable, and it is more accurate to calculate hourly fuel consumption.
2. Calculation formula of hourly fuel consumption: 100 km fuel consumption/100* limit *0.8 (the limit speed is the highest safe speed) is a standard for formatting statistics. The slower the vehicle travels within the economic speed, the more fuel it consumes per 100 kilometers, and vice versa. If the engine speed is controlled within the same safe speed, the fuel consumption per hour is the same regardless of the vehicle speed.
3. The economic index of automobile is mainly expressed by fuel consumption, which is an important part of automobile performance. When the vehicle is driving at an economical speed, the slower it is, the more it consumes, and the less it consumes when it exceeds the economical speed. There are many factors that affect fuel consumption. In addition to the different displacement of different models, it depends on road conditions, car performance and driver's skills.
4. The fuel consumption of an automobile refers to a fuel index calculated by the value measured through repeated tests when the vehicle is driving at a specified speed and time on a specified road, also known as the road cycle fuel consumption under multifunctional conditions. It is stipulated in the specification that each cycle contains various driving power conditions, and the driving power conditions are recorded according to the indicators such as shift time, parking time, driving speed, acceleration, braking and deceleration specified in each cycle.
1. Factors affecting automobile fuel consumption: automobile fuel consumption is also directly related to tire pressure. For vehicles without tire pressure detection display, many car owners often ignore the importance of tire pressure. If the tire pressure is too high or too low, the fuel consumption of the car will increase. The road condition of the car will also have an impact on fuel consumption. If the car often runs on roads with poor road conditions, the load generated by the engine will increase, so the fuel consumption of the car will naturally increase.
2. Generally speaking, the displacement of the engine has a certain influence on the fuel consumption of the car, but this influence is a fixed value. Therefore, the displacement of the engine has no great influence on the fuel consumption of the car, and some external factors will affect the fuel consumption of the car.
3. First of all, talk about the driver's driving habits. The fuel consumption of a car is closely related to the driver's driving habits. If the driver often jerks on or accelerates or decelerates during driving, it will affect the fuel consumption of the car. According to statistics, incorrect driving habits will lead to an increase in car fuel consumption of 5-30%.
