Electronic governor for internal-combustion engine

Abstract

Abstract PURPOSE:To perform start incremental control without causing unstable engine operation by providing a start detection circuit for producing a start detection signal when the magnitude of integrated signal or operating signal is lower than the lower limit under normal operation. CONSTITUTION:Initial setting circuit 12 for producing an initial signal Vo when a speed sensor 3A is not producing an output is provided. Start detection circuit 11 will produce a start detection signal Vs when the operating signal Vh is lower than the lower limit Vy or the integrated signal Vi is lower than the lower limit Vy. While control element 10 will function the rack operating means 2 such that the rack is forcibly moved to the full-open position when the initial setting circuit 12 is producing the initial signal Vo. Consequently, the start incremental control can be executed without causing unstable engine operation.
