Abstract: The disclosure relates to a system and method for sizing of system components in a dual fuel port injection system. The system includes a pressure regulator and a safety shut-off valve that feeds a main gas rail. The gas rail is operatively connected to a gas admission valve by a gas jumper tube. The gas admission valve is operatively connected to a gas admission port in a cylinder head or to an intake runner via a gas delivery tube. The gas admission valve has an effective cross sectional area that is defined by the actual cross sectional area multiplied by a modifying coefficient. The components of the system are sized based upon the effective cross sectional area of the gas admission valve.

Abstract: The disclosure is directed to an intake system for a machine, the intake system including a connector including an inlet portion, a mixing portion and an outlet portion where the connector is configured to flow air sequentially through the inlet portion, the mixing portion and the outlet portion within the connector, a fuel admission valve input where the fuel admission valve input is connected to an outer surface of the connector and is configured to receive fuel that subsequently enters inside the connector and a fuel admission point placed within the connector. The fuel admission point is configured to receive the fuel from the fuel admission valve input and introduce the fuel inside the connector. The fuel admission point is further configured to introduce the fuel inside the connector at an angle with respect to an airflow through the connector to generate a turbulent flow and cause mixing of air and fuel.
