Numerical analysis of needle eccentricity effects on internal flow of enlarged VCO diesel injector
The VCO (Valve Covered Orifice) nozzle is known to reduce unburned hydrocarbon emission from direct-injection diesel engine. However, high-pressure fuel injection causes needle eccentricity which results in non-uniformity of sprays and deterioration of emission characteristics. Present study numeric...
