The fuel injection and peak fuel injection pressures of a liquid fuel compression-ignition engine, such as a diesel engine or a diesel engine burning an alternative liquid fuel, are affected by fuel physical properties, and various engine design and operation input parameters. The fuel physical properties under this investigation include fuel density, fuel bulk modulus of elasticity, and fuel viscosity. The design and operation input parameters studied include the engine speed and the injector nozzle configuration parameters, such as the number of holes per injector nozzle, the dimensions of the hole, and the nozzle fuel flow discharge coefficient. The work of this paper analytically investigates the effects of those input parameters on pump-to-injector line fuel pressure and peak pressure. An understanding and simplified modeling of the fuel peak pressure affected by those property and input parameters are developed. The variations of the fuel pressure parameters over varying the fuel properties and the input parameters are analyzed and predicted. Results from this study indicate that, as the fuel bulk modulus of elasticity varies, the initial fuel pressure build-up period would be affected more significantly, with a less-significant variation in the fuel-line peak pressure. Among those fuel physical properties, the fuel density has a relatively significant effect on the fuel peak pressure. The effects of the various design and operation input parameters on the fuel peak pressure and related injection parameters are also studied and presented.
