Cng Regulator Factory introduced that the biggest difference between single-point and multi-point is the way of air intake (natural gas). The single point is that the natural gas is directly supplied through the throttle valve of the vehicle after the three-stage decompression of the pressure reducing valve, and the size of the intake air is controlled according to the different vacuum degrees of the vehicle's intake system.
The multi-point system is that the natural gas passes through several solenoid valves (one for each cylinder) after being decompressed by the pressure-reducing valve. The solenoid valve controls the air supply size according to the computer signal. The solenoid valve supply needs to be marked on the engine intake pipe. The hole can ensure the air supply for each cylinder. The single point is the air intake from the very beginning of the intake pipe, and the multi-point is the air intake from the end of the intake pipe.
Regarding the issue of single-point blasting and insufficient power, many refitting factories attribute the problem of blasting to the single-point system. In fact, the blasting of gas vehicles is almost all caused by the ignition system. Will set off. The power of gas is 15% lower than that of fuel. This is determined by the nature of the fuel, and it cannot be solved by a single point and multiple points.
The most important thing is the later use and maintenance. The single-point system is simple and has low maintenance cost. It does not need to modify the original car engine, but the system stability is a bit poor and requires frequent debugging. The multi-point system is relatively stable, but the maintenance cost is high, the maintenance is very complicated, and the air intake pipe of the original car needs to be modified.
So "oil to gas" cannot simply say which is good or which is not good. You should choose according to your car's structure and car usage habits. If your car has a long intake pipe, or if your car is older, you can choose a multi-point system. If your car's intake pipe is very short, and you try not to change the original car parts, you can change it to a single point.
