description	PURPOSE: An engine control system of construction machinery is provided to possessively cope with a low idle state of an engine by increasing an engine RPM at a predetermined level, thereby improving fuel and work efficiencies. CONSTITUTION: An engine control system of construction machinery comprises an RPM selector(100), an operation input unit(200), a speed controller(5), and an equipment controller(3). The RPM selector is an RPM selecting switch or a monitor and receives the input of RPM from a user. The operation input unit includes a hydraulic control lever(1), a steering handle, an electronic steering lever and travelling switch(11), and a gear selector. The equipment controller controls the speed controller to maintain the selected RPM when the input of the operation input unit is sensed. [Reference numerals] (1) Hydraulic control lever; (10) User interface supportable monitor; (100) RPM selecting switch; (11) Electronic steering lever and travelling switch; (13) Pressure sensor; (3) Equipment controller; (5) Speed controller for low-speed regions of an engine; (8) Hydraulic main P/P; (AA) Steering handle; (BB) Left; (CC) Right; (DD) Low-speed region 1; (EE) Low-speed region 2; (FF) Low-speed region 3
