Q3 of 14 is very expensive. What happened?

Q3 of 14 consumes a lot of fuel, and the throttle may be dirty. The contact gap of spark plug is too large. There are also external factors. Wind resistance of tire pneumatic driving. Road conditions will increase fuel consumption. If fuel consumption can't be reduced, then change driving habits and routes, because road conditions and driving habits are the factors that affect fuel consumption. Then another factor is that the oil in the gearbox is too viscous, which will also lead to an increase in fuel consumption. The most common factor is that too much carbon deposits in the engine will reduce the atomization effect of the fuel injector, and the fuel consumption will naturally be high.

Causes and solutions of increased oil consumption

If abnormal noise is found in the wheels when driving or starting, check whether the bearing and braking system are faulty in time. If the wheel rotates abnormally, it will affect the speed and increase fuel consumption. Overhaul the bearing and braking system. When your car travels 200,000 to 300,000 kilometers, there will usually be insufficient cylinder pressure and fuel consumption will increase significantly. If this kind of fault really occurs, then the engine needs to be overhauled.

The exhaust pipe emits black smoke and the fuel consumption increases, so it is necessary to check the carburetor. If the carburetor is too dirty, you can spray cleaning agent directly to the intake of the carburetor. If there is still black smoke at this time, the carburetor will have to be disassembled and cleaned. If the spark plug is used for too long, the fuel consumption will also increase. Because the damage of spark plug will reduce the ignition energy and slow down the vehicle speed, resulting in a significant increase in fuel consumption. It's time to change the spark plug.
