<p>The device comprises substantially an integral connection block (5) for connection to an air manifold (1) and to an engine wall (7); in said block there is provided a plurality of pairs of main air feed holes (15, 16), one hole (16) of each pair being controlled by a throttle valve (17); in the block there is also provided a series of supplementary idling air ducts (18a, 18b, 19a, 19b) the passage of which is controlled by a solenoid modulating valve (22) housed in a suitable seat (21) in the block. On the block there is also provided a series of seats (23) for the injectors (24), and a pair of ducts (26, 27) for feeding fuel to the injectors and for its recirculation. Finally, on the block there are provided further seats (30, 43) for a fuel pressure regulator (31) and for a pneumatic actuator (44) arranged to control said throttle valves by way of a transmission (45).</p> |
