How to adjust the fuel consumption of oil-to-gas vehicles?

Many adjustments are made by computer. Generally, the combustion ratio of gas is used to adjust the rotation speed during conversion. The air-fuel ratio of gasoline engine is 1: 14. Like natural gas, an appropriate mixing ratio (the ratio of air to natural gas entering the engine) is required. Under normal circumstances, there is generally not much to be adjusted when a new car is converted into natural gas.

But the old car is different, and all the working conditions are not very good. At this time, the intake volume of CNG and idle air should be changed according to the situation. Vehicle deviation is also one of the main reasons for fuel consumption, and four-wheel imbalance will make the engine eat more power. If the gas consumption suddenly increases, mostly due to loose joints or lax sealing, it should be checked at the professional maintenance site in time to avoid further accidents caused by gas leakage.

Extended data:

The maximum air consumption is the amount of air browsing required when the cylinder moves at the maximum speed, which can be expressed as:

qr=0.0462D^2*um(P+0. 102)

For example, if the cylinder diameter d is 10cm, the maximum speed is 300mm/s and the working pressure is 0.6Mpa, the maximum air consumption QR of the cylinder is 0.046 *102 * 300 * (0.6+0.102) = 968.76.

If the working pressure of the cylinder is 0.5Mpa and the maximum speed is 200mm/s, the maximum gas consumption of the cylinder is qr=553.84.

If the cylinder diameter d is 50cm, the maximum speed is 300 mm/s, and the maximum gas consumption of the cylinder is qr=242. 19 when the working pressure is 0.6Mpa, then the cv value is about 0.3.
