How long can the car idle and consume 1 liter of oil?

The car runs at idle speed for about 1 hour, and can consume 1 liter of engine oil.

1: The fuel consumption at idle is about 1~2 liters/hour, and it is about 0. 1~0.2L in three minutes.

2. The fuel consumption of ordinary cars is about 0.1liter per kilometer, which is equivalent to about 0. 1L per kilometer.

3: The fuel consumption of idling for three minutes is really equivalent to the fuel consumption of one kilometer.

Extended data:

(1) Generally speaking, the idling condition refers to the condition that the car is in neutral, the car is parked in the same place, and the engine keeps the lowest speed.

(2) The rotation of the engine mainly maintains the operation of air-conditioning compressor, water pump and flywheel. If the clutch is engaged at this time (without stepping on the clutch pedal), the engine will also drive the gears and other parts of the input shaft of the gearbox to run. Therefore, the idling of the engine also consumes fuel.

(3) At low speed, the air intake of the engine is also low, the fuel combustion is insufficient, the movement energy loss of mechanical parts (such as valves and pistons) is large, and the overall mechanical efficiency of the engine is low, so the fuel consumption is high. This is why the engine consumes a lot of fuel when idling.
