Is automobile fuel consumption affected by temperature?

Hello! Oil consumption has a certain influence on the temperature, and the oil consumption in winter will be higher than that in summer. Due to the low temperature in winter, the engine needs to do more work to reach and maintain the working temperature, and the corresponding fuel consumption is also more. It seems to have some influence. It is said that high fuel consumption in winter has an impact. The main reason for the increase of fuel consumption of EFI vehicles in winter is preheating, and the preheating time should not be too long. Warm up for about a minute, and you need to drive at a low speed for several kilometers. The reason is that even if the engine is hot, the mechanical transmission system will not heat up. This part requires a trip, and the fuel consumption of short-distance vehicles will increase. Because the idle fuel consumption is proportional to the displacement. Hello 1, the engine needs to be maintained at room temperature, about 90℃. If the temperature is too low, the engine control system will increase fuel injection and change the ignition advance angle to increase the engine speed. 2. The temperature is low in winter, and the viscosity and low-temperature fluidity of engine oil are relatively poor. Especially after the vehicle is parked overnight, the engine oil has generally sunk to the bottom of the cylinder. After the vehicle is started, the lubrication effect of each part in the cylinder is not good, and the engine resistance increases, resulting in an increase in fuel consumption. Using warm air in the car in winter will also increase fuel consumption. Hot air can warm the cab. However, if the hot air is insufficient or cannot reach the set temperature, the engine will do extra work and generate more heat energy. In order to increase the cab temperature, this requires additional fuel consumption. 4. In low temperature environment, the thermal efficiency of gasoline is far less than that in high temperature environment. These factors naturally make the fuel consumption of cars in cold weather in winter higher than in other seasons. Reference. @20 19
