Abstract

PURPOSE:To obviate any engine stall due to hydraulic coupling load by operating an exhaust shutter in the opening direction at the time of travel range stoppage warming up, in case of an automatic transmission car. CONSTITUTION:In case of an automatic transmission car made up of interposing a torque converter between an engine 1 and an automatic transmission, an exhaust shutter 5 functioning as an exhaust brake and for warming up is installed in an exhaust pipe 4 of the engine 1 free of opening or closing. Here a controller 13 judges that it is at the time of travel range stoppage warming up if a warming switch 14 is opened, and a car speed switch 15, a neutral switch 17 and a parking switch 21 are all opened, whereby it makes a three-way solenoid valve 9 come into a nonexciting state. With this constitution, a diaphragm mechanism 11 is interconnected to the atmospheric side and thereby the exhaust shutter 5 is opened. In consequence, a rise in exhaust pressure is brought to nothing and torque converter load only comes to be imposed on the engine 1, thus the occurrence of an engine install is obviated.
