Fuel feed apparatus for liquid or gaseous fuels

摘要

The IC engine has a single injector (5) for each cylinder. For running with liquid fuel the injectors are connected to a fuel feed line (6) with a pressure controlled (7) fuel feed. Air is also fed to each injector via an air feed line (10a) and a control valve (9). For running with gas fuel the liquid fuel line is closed and gas fuel is dosed into the air line (8) and distributed to each injector. The gas feed is via a dosing unit (11). This is connected to a processor control as are the injectors, the flow control valve and other engine control systems. The processor control allows a simple and rapid switchover between liquid fuel and gas fuel.
