ENGINE STALL PREVENTING DEVICE FOR ENGINE WITH TURBOSUPERCHARGER

摘要

PURPOSE:To prevent engine stall due to shocks at the time when a clutch is connected, without increasing the number of parts regardless of the skill of clutch operation or the depressing amount of an accelerator pedal. CONSTITUTION:An air supply pipe 33 branched from a conductor 17 for introducing the boost pressure of an engine 10 with a turbo charger into a boost compensator pressurizing chamber 21 is connected to a compressed air source 36 through a pressure reducing valve 34, and a change-over valve 37 is provided at the branched place. When the rotating speed of the engine is decreased to a specified rotating speed lower than an idle rotating speed at the time of increasing the engine load, a controller 40 controls the change-over valve 37 to introduce the compressed air of the compressed air source into the pressurizing chamber 21.
