PCT No. PCT/SE94/00647 Sec. 371 Date Mar. 7, 1995 Sec. 102(e) Date Mar. 7, 1995 PCT Filed Jun. 30, 1994 PCT Pub. No. WO95/02119 PCT Pub. Date Jan. 19, 1995An arrangement and method for regulation of idle speed and charge pressure in a supercharged combustion engine (1) which engine includes an idle speed valve (20) arranged in a shunt channel (21) by-passing the throttle (9) and a gate valve (10) regulated by a pressure controlled diaphragm pot for regulating of the supercharger. The valve (20) is used both for regulation of idle speed and charge pressure by an arrangement of ducting (23, 24, 25, 19) and a shut-off valve (26). A control device (31) includes different functions for regulation of idle speed and charge pressure. The function selected for regulation by the control device depends on an engine parameter, such as throttle position, detected by a throttle position sensor (16). |
