Idling a car for 50 minutes without moving does consume fuel. The details are as follows: 1. Idle state: When the car is started but not moving, it indicates that the engine is in an idle state. Idle state refers to the engine running without load, with the engine speed generally between 550-800 RPM. Prolonged idling can easily cause carbon buildup in the engine. 2. Temperature: Both high and low idle speeds are undesirable. A high idle speed can affect fuel consumption, potentially increasing engine fuel consumption, raising internal engine temperature, and accelerating engine wear, thereby reducing the engine's lifespan. Conversely, prolonged low idle speed can cause the car to stall. Stalling can occur in two scenarios: one during idling and the other while the car is in motion. Many car owners prefer to warm up the engine by idling in cold temperatures. While this method can be used, the idling time should not be too long. Idling for about one minute is sufficient. Once the RPM stabilizes, using a low-speed driving method can warm up the car. Additionally, it's important to control the engine speed, keeping it below 2000 RPM. This method not only saves fuel but also minimizes the risk of carbon buildup in the engine.

What is the fuel consumption of the Jetour X70?

The 2022 Jetour X70 has 2 models on sale: the 1.5T-Manual Lexing Edition-5-seater and the Manual Lexing Edition-7-seater, both equipped with a 1156 horsepower engine, with an NEDC fuel consumption of 7.5L per 100 km. The fuel tank capacity of different Jetour X70 models is the same. The distance that can be covered with a full tank of fuel is as follows: For models equipped with a 156 horsepower engine and an NEDC fuel consumption of 7.5L per 100 km, the fuel tank capacity is 55L, and the distance that can be covered with a full tank is 55/7.5*100=733 km. The fuel consumption of a car is directly related to five major factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. Specific factors that can increase fuel consumption are as follows: Driving habits: Aggressive driving, such as sudden acceleration, frequent overtaking, and not easing off the throttle before a red light, can increase fuel consumption. The car itself: Cars with larger engine displacements generally consume more fuel than those with smaller displacements because larger displacements usually mean higher power, requiring more gasoline to burn and perform work. Heavier cars also consume more fuel because greater weight requires more driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases car resistance and fuel consumption. Low environmental temperatures: When the engine block is cold, the gasoline injected during a cold start does not atomize easily, requiring more gasoline to be injected for combustion, which increases fuel consumption. Additionally, in low temperatures, the engine's computer controls higher RPMs to warm up the car, which also increases fuel consumption.
