The fuel metering system employs a throttle plate (4) inserted in the air intake (3) for the engine controlling the vol. of air supplied. The amount of fuel fed to one or more fuel injection valves (2) is simultaneously adjusted in accordance with the setting of the throttle plate (4). The ratio of the supplied air to the injected fuel may remain constant over the full engine operating range, or may be altered in dependence on a detected engine parameter, e.g. the engine operating temp. |
