Determination of Valve Gate Open Timing for Minimizing Injection Pressure of an Automotive Instrument Panel [PDF]

Transactions of the Korean Society of Automotive Engineers, 2012
Injection pressure, an important factor in filling process, should be minimized to enhance injection molding quality. Injection pressure can be controlled by valve gate open timing. In this work, we decided the valve gate open timing to minimize the injection pressure.

Effect of boosting on a performance and emissions in a port fuel injection natural gas engine with variable intake and exhaust valve timing

Energy Reports, 2021
Recently, many studies have been conducted on the conversion of conventional fossil fuels to alternative fuels. Natural gas is one of the best alternative fuels because it is a low-carbon fuel. In natural gas engines, port fuel injection is generally adopted rather than direct injection because of the compatibility of the injection system in a positive
