Claim Text:
1. A control system for a dual-fuel engine, comprising: a gaseous fuel injector having a nozzle located at a first air intake port of a cylinder of the engine and configured to inject a variable amount of gaseous fuel radially into the cylinder based on at least one of a load and a speed of the engine; a liquid fuel injector configured to inject a fixed amount of liquid fuel axially into the cylinder based on the at least one of the load and the speed of the engine; a regulator configured to selectively adjust a flow of gaseous fuel to the gaseous fuel injector; at least one sensor positioned at a second air intake port of the cylinder and configured to generate a first signal indicative of a first performance parameter of the engine wherein the first performance parameter is a presence of gaseous fuel that has exited the cylinder through a second air intake port; and a controller in communication with the regulator and the at least one sensor, the controller being configured to selectively cause the regulator to adjust the flow of gaseous fuel based on the signal.
