Simulation of gaseous fuel injector geometries of mult holes nozzle by using CNG engine

Compressed natural gas (CNG) is the most preferred for fossil fuel substitution. This project is to study simulation of gaseous fuel injector geometries of multi-hole nozzle by using CNG engine. Three main components are focused on this paper. First, the relation between engine speed and injector pr...

Hashim TJ Mechanical engineering and machinery Compressed natural gas (CNG) is the most preferred for fossil fuel substitution. This project is to study simulation of gaseous fuel injector geometries of multi-hole nozzle by using CNG engine. Three main components are focused on this paper. First, the relation between engine speed and injector pressure in achieving stoichiometric airfuel mixture is investigated.

The results are shown; by increasing the engine speed, the injector pressure increases at different valve lift. Valve lift increment will increase the injector pressure for different engine speeds but the injector pressure is constant for valve lift increment from 75 percent to 100 percent.
