How much is the idle fuel consumption of the car?

【 Bang Master 】 How much is the idle fuel consumption of the car?

When buying a car, in addition to considering the cost of the current payment, the cost of car ownership should also be carefully considered, after all, the cost required in the later period is long-term, which is like boiling a frog in warm water, a single stroke of expenditure, payment will not feel anything. But if you add up all that money, it's not a small number.

Although the same class of models are basically similar in terms of maintenance costs, the fuel consumption at idle can be said to be very different.

What is the idle fuel consumption of the car

Cars usually idle fuel consumption at 1-2 liters, gasoline cars idle at about 800 RPM, the higher the displacement of the car, the more fuel consumption per hour idle.

The level of idle fuel consumption is directly related to the size of the displacement and the level of idle speed.

And even if it is the same car, its engine run-in, the condition of the car and the effect of air conditioning refrigeration will affect the level of fuel consumption.

What causes increased fuel consumption at idle

1

Oxygen sensor failure

The failure of the oxygen sensor can cause the engine computer data to be inaccurate, resulting in increased fuel consumption.

2

Tire pressure is too low

The increase in the contact area between the tire and the ground will not only lead to increased fuel consumption, but also bring many safety risks. Especially when running at high speed, tire pressure is too low and it is easy to burst a tire.

3

The air filter is blocked

We can also replace the air filter, the air filter is not replaced for a long time will be blocked, resulting in insufficient engine intake, fuel can not be fully burned, resulting in increased fuel consumption.

4

Engine carbon deposit

When the car is driven for a long time, the engine will more or less produce some carbon deposits, especially when the vehicle is often driven at low speed, it is easy to have too much carbon deposits in the engine. Too much carbon will cause the engine to be underpowered and fuel consumption will increase.

5

Aging of spark plug

The car travels about 50,000 kilometers, and the spark plug almost needs to be replaced.

Spark plug aging will lead to weak ignition performance, insufficient engine power, then in order to provide enough power to the car, the engine will consume more fuel, so fuel consumption will increase.

In addition, there are many reasons for increased fuel consumption, in addition to auto parts, oil quality problems, the driver's driving habits will also lead to increased fuel consumption. There is also that when you find that the car has an abnormal situation, you should go to the 4S shop in time to check the root cause of the disease in order to better save fuel.
