Production Description:

At clean energy, low-carbon fields, we provide a safe, clean energy (compressed natural gas) conversion equipment. Using the most advanced control technology and advanced integrated design and closed-loop control technology. A single point of self-absorption control system for closed-loop model covers a variety of 4,6,8-cylinder engine; use the most advanced combination gas valve, no leakage; working pressure 20MPA to 35MPA and hydrogen conversion system optional. Applicable to a variety of well-formed gas premixed with a naturally aspirated engine motorcycle, car, bus, city bus.
 
Single Point Injection (SPI) system background knowledge:
In the top of the intake manifold throttle installed a central injection device, with l ~ 2 were gushing oil concentration of injection devices. Gasoline spray into the air flow in the human form of the combustible mixture from the intake manifold of the distribution to each cylinder. A single point of injection, also known as throttle body injection (TBI) or central fuel injection (CFI). Single-point injection system cost is lower, only slightly higher than the traditional carburetor. At present, domestic and international popular sedans been widely used.
A single point of jet injectors in the throttle at the top can only improve the throttle at the spray in order to heat the wall temperature has increased the degree of fuel evaporation is difficult to ensure the throttle to the intake valve after the section of the wall does not form a film or oil droplets, so the structure of the intake manifold of mixed gas transmission and distribution have a significant impact, but can be difficult to achieve in all operating conditions to maintain the ideal mixture of gas distribution.
    A single point of injection in which a very significant advantage is that single-point injection throttle injectors located in the top of the high speed directly to the air intake pipe injection, because of the low pressure (inversely proportional to velocity and pressure), spraying only need to be able to 0.1MPA low-voltage, multi-point injection will have to work in the 0.35Mpa only, which means that a single point injection system can reduce the demand for electric fuel pump, saving costs.
