Bread throttling

The first reason for the high fuel consumption of automobiles;

Even if the driving skill is low, the fuel consumption of the same car and different people will be different. Only by summing up experience and improving driving level can we solve the problem of high fuel consumption caused by driving technology.

The second reason for the high fuel consumption of automobiles:

There is something wrong with the spark plug and high voltage line of the gasoline vehicle, which leads to the abnormal ignition circuit. Therefore, high fuel consumption can be solved by repairing and replacing another part.

The third reason for the high fuel consumption of automobiles:

There is something wrong with the brake system, the brake pads do not return, and the driving resistance increases. Oil consumption can be reduced through maintenance and recycling.

The fourth reason for the high fuel consumption of automobiles:

The automobile oil circuit is not smooth and the carbon deposit is blocked. Clean the fuel injector and throttle with fuel cleaner. Can reduce fuel consumption.

The fifth reason for the high fuel consumption of cars is that the air filter is dirty and the air is not smooth, which leads to the wrong oil-gas ratio. The filter element needs to be replaced.

The sixth reason of high fuel consumption of automobiles: high fuel consumption is caused by high temperature and humidity in summer and seasonality.

The seventh reason for the high fuel consumption of automobiles: fast driving speed, heavy automobile load and high fuel consumption.

The eighth reason for high fuel consumption of automobiles: gasoline quality is not up to standard, which leads to high fuel consumption.

The ninth reason of high automobile fuel consumption:

Metal wear. After running in for 2,000 kilometers, the surface roughness of cylinder wall and piston ring can be reduced to Ra=0.2 micron, the clearance between cylinder and piston is also the smallest, the valve seal is also the strictest, and the fuel consumption of automobile is naturally the least. After the average domestic car travels 50000- 100000 km, the metal friction surface is gradually worn and uneven. At this time, the wear rate is several times to ten times higher than that of a new car. After the metal is worn, the gap between parts increases, the friction resistance increases, and the cylinder pressure decreases, which inevitably leads to oil channeling and gas channeling. Loss increases, efficiency decreases, power performance decreases, and automobile fuel consumption naturally increases. Some cars even consume 20-30% more fuel than new cars. In order to restore the high fuel consumption of a car to the standard of a new car, the most effective way in the past was to overhaul the boring cylinder and replace the piston and piston ring. Restore the dimensions of the original car parts. But the cost is high and the time is long.

Recently, a new technology that can improve power and reduce fuel consumption has been popularized and used, and the wear is extremely low (about zero) when the car travels 654.38+ 10 thousand kilometers.

Fine running-in and metal self-repair technology of cermets in xinba. The fine running-in technology of NWFB is suitable for new cars to run 2000 kilometers. After use, the surface roughness of cylinder wall and piston ring becomes smaller, reaching Ra=0.02 micron, which is 10 times lower than that of non-precision running-in, and the friction resistance is reduced by 50-80%. It is also reasonable to solve the problem of high fuel consumption caused by large friction resistance of parts. The metal self-repairing technology of NWFB is suitable for vehicles with unburned engine oil of 200-65438+100000 km, and can self-repair the cylinder pressure drop caused by cylinder wear. The most obvious effect is to restore power and let the car with high fuel consumption return to the level of a new car.
