IC engine with automatic gear control and mechanical regulator for fuel-injection pump - has charge pressure and/or atmospheric pressure-dependent pressure box and engine torque not to be processed for automatic gear connectable to vacuum connection

摘要

The rotational speed governor 3 has a capsule 5 subject to boost pressure and/or atmospheric pressure and connected to vacuum from a pump 15 when a valve 13 is switched by a signal from a control unit 12 to reduce engine torque. The unit 12 receives signals from a capsule pressure sensor 8, an accelerator pedal position sensor 10 and an engine speed sensor 11. The vacuum is applied to the capsules when the engine torque is excessive for the gearbox. <IMAGE>
