Abstract
An internal combustion engine air supply system having a first air intake passage (11) through which air can flow to the engine (8) with a driver actuated mechanism operatively coupled to a first control means (12) to vary the air flow through the primary passage (11) to the engine (8) in response to the driver demand and a second air intake passage (13) through which air can flow to the engine (8) with an actuator means operable in response to sensed engine operating conditions to operate a second control means (5) to vary the air flow through the second passage (13) to the engine (8); the first control (12) means and second control means (5) being operable independently, so that the air supplied to the engine (8) may pass solely through one of the first (11) or second (13) air passages or simultaneously through both.
