摘要

Apparatus (10) for controlling the air to gas ratio of fuel supplied to a gas engine (12) that includes a conduit (22) connecting the carburetor (28) to the intake manifold (14) of the engine (12). A throttle valve (24) is located in the conduit (22) for varying the flow area therethrough in response to load changes on the engine (12) and a regulator device (32) including a controller (46) and gas regulator (32) for changing the air to fuel gas ratio of fuel supplied to the engine (12) in response to the position of the throttle valve (24).
