DEVICE FOR EMERGENCY SHUTTING DOWN OF INTERNAL COMBUSTION ENGINE AND DECELERATION OF VEHICLES BY ENGINE Russian patent published in 2006 - IPC F02D17/04 F02B77/08 

FIELD: mechanical engineering; engines.

SUBSTANCE: invention relates to devices for disconnection of engines in case of emergency situations and to compression brakes of engine trucks. Device for emergency shutting down of internal combustion engine and deceleration of vehicle by engine contains member for closing section of intake pipe line, closing member position setter and compressed air source. Closing member position setter is made in form of crankshaft speed limit pickup, oil pressure drop pickup, cooling liquid temperature rise pickup, and engine retarder control pushbutton. Intake pipeline section closing member is made in form of spool series-connected by pneumatic cylinder, in upper part of which calibrated hole communicating with atmosphere is made with fuel-feed valve connected with fuel-feed main line and with each of above-indicated pickups through check valve, and signal lamp and with engineering retarder control pushbutton and is connected in series with compressed air source. Pickups and engine retarder control pushbutton are connected in parallel.

EFFECT: improved reliability and efficiency of engine in operation, enlarged functional capabilities.
