Abstract: A fuel system for an engine is disclosed. The fuel system may have a first fuel injector configured to inject a first stream of gaseous fuel radially into a combustion chamber of a cylinder of the engine through a first air intake port. The fuel system may also have a second fuel injector configured to inject a second stream of gaseous fuel radially into the combustion chamber through a second air intake port to collide with the first stream of gaseous fuel.

Abstract: A fuel system for an engine having a cylinder liner is disclosed. The fuel system may have a gaseous fuel injector having a nozzle located at an air intake port of the cylinder liner. The gaseous fuel injector may be configured to inject gaseous fuel radially into the cylinder liner at an oblique vertical angle with respect to a plane perpendicular to an axis of the cylinder liner. The fuel system may also have a liquid fuel injector configured to inject liquid fuel axially into the cylinder liner.

Abstract: A fuel system for an engine has a cylinder with an inlet air port, an air box surrounding the inlet air port, and a gaseous fuel injector positioned in the air box and having a nozzle located at the inlet air port. The fuel system also has a gaseous fuel control valve, a fuel supply line fluidly extending from the gaseous fuel control valve to the gaseous fuel injector, a purge valve, and a purge fluid supply line fluidly extending from the purge valve to at least one of the fuel supply line and the gaseous fuel injector. The fuel system also has a return valve and a return line fluidly extending from at least one of the fuel supply line and the gaseous fuel injector.

Abstract: A control system for an engine is disclosed. The control system may have a first gaseous-fuel injector configured to inject gaseous fuel into a first intake passage associated with at least a first cylinder and a second gaseous-fuel injector configured to inject gaseous fuel into a second intake passage associated with at least a second cylinder. The control system may also have a variable orifice disposed within the second intake passage upstream of the first gaseous fuel injector. The control system may additionally have a sensor configured to provide a signal indicative of a performance parameter of the engine and a controller electronically connected to the variable orifice and the sensor. The controller may be configured to move the variable orifice to adjust a ratio of air-to-fuel in the first and second intake passages based on the signal.
