FIELD: transport engineering. SUBSTANCE: proposed device can be used for effective evacuation of exhaust gases at standing before road crossing or traffic light. Device contains exhaust pipe installed for displacement under action of drives relative to car body and connected with hole in reservoir for utilization of exhaust gases, dc voltage source, control unit connected by supplied terminals to corresponding lead outs of dc voltage source. Drives for providing transverse, vertical and longitudinal displacements of lower end of exhaust pipe three noncontact induction pickups are connected with control unit. Control system makes it possible to accurately install lower end of exhaust pipe over inlet hole of exhaust gas gathering reservoir and provides its tight fitting to hole at forced standstill and before road crossings. EFFECT: reduced time taken for accurate and quick connection of lower end of exhaust pipe with hole of exhaust gas gathering reservoir for subsequent utilization of gases. 3 cl, 2 dwg |
