Abstract

The air supply to the engine inlet valves (13) is formed by an air entry (15), a filter (16) and a throttle (18). The throttle can be part of a carburettor and is controlled by a cable (27) from the accelerator pedal (28). An auxiliary inlet (22) admits a controlled proportion of preheated air upstream of the filter (16). A Helmholtz resonator (30) has a neck (32) opening into the air supply system between the filter (16) and the throttle (18). A vane (31) in the neck (32) of the resonator is controlled by a cable (34) from the throttle (18). The natural frequency of the resonator is thus made to vary with the air intake so that the resonator is effective in increasing the volumetric efficiency over the whole range of the engine output.
