Design of Natural Gas Ejector in the Engine

Abstract:

in order to meet the requirements of the supplying system of CNG engine to the mixed state of fuel and the ejection time control of fuel, the overall structure of CNG fuel ejector is given. The structural characteristics of the main components of the CNG ejectors are analyzed and the structure parameters which have significant effect on the performance of the ejector are designed and calculated. Through the calculation on the through-hole diameter, spring, coil and minimum wall thickness, it is indicated that the designed ejector satisfies the demand of the jet pressure and jet control.
