HYBRID4 NMT – TNGA Engines – Variable Flow Cooling System
Flow shutting valve
When there is no current applied to the flow shutting valve and the
water pump operates, the valve opens due to engine coolant pressure
When the flow shutting valve is closed and electric current is applied, a
magnetic field is generated between the yoke, valve and core, which
keeps the valve closed
The opened valve remains open until the engine coolant flow stops
