• This chapter describes a Yanmar second-generation electronic governor (herein referred to as the “Gen2 Eco-governor”) that conforms to the third EPA regulation by controlling Exhaust Gas Recirculation (EGR). The Gen2 Eco-governor is standard equipped on NV3 and supercharged engines.
• It is also available as an option for other engines. Contact Yanmar for details. The engine electronic control unit (E-ECU) controls the speed and power of the engine by adjusting the rack position of the fuel injection pump depending on the signal from the accelerator sensor.
• The opening of the EGR valve is adjusted depending on the engine speed and load factor so as to ensure conformance to exhaust emission standards. The Gen2 Eco-governor provides control to the engine depending on the throttle position, coolant temperature, external-switch positions, signals through CAN or other parameters and is superior to a mechanical governor in versatility.
