What is the fuel consumption for 180 horsepower idling for 1 hour?
2 Answers
Idling for 1 hour consumes approximately 1L of fuel. Introduction to idling: Idling is a working condition of a car, referring to the engine running in neutral gear. The engine speed during idling is called the idle speed. The idle speed can be adjusted by changing the throttle size, among other methods. Idling means the engine "outputs power without doing work," and it is important to avoid prolonged idling. Driving idle: When the car is in gear, without pressing the accelerator pedal or releasing the accelerator pedal while driving, maintaining the minimum throttle opening, the engine speed matches the parking idle speed. This state is referred to as driving idle.
I often pay attention to fuel consumption while driving. A 180-horsepower engine consumes approximately 1.5 to 2.5 liters of gasoline per hour at idle, depending on the vehicle condition and environment. For example, my sedan with a 1.8T turbocharged engine consumes about 1.8 liters of fuel per hour during idle tests. Many factors affect fuel consumption, such as whether the engine is cold-started or whether the air conditioning is on. Turning on the air conditioning can increase fuel consumption by about 0.5 liters. It is recommended to avoid prolonged idling, especially in traffic jams, as turning off the engine for a minute saves fuel and protects the engine. In daily use, regular oil changes and air filter replacements can improve efficiency. After purchasing a car, conducting an idle test is more accurate—just measure it with a fuel consumption meter. Energy-efficient driving not only saves money but also contributes to environmental protection.
