outboard boat marine water temperature gauge

Our water temperature gauge can be installed on your outboard boat marine . At present, the outlet water temperature of marine diesel engines is generally too low, which makes the diesel fuel unable to burn completely. The oil viscosity is high, and the running resistance of the diesel engine is correspondingly increased, and the diesel fuel consumption is increased; Excessive water temperature, overheating of the outboard boat marine diesel engine, insufficient intake air, reduced cylinder compression pressure, and incomplete combustion of diesel fuel can also increase fuel consumption. One of the main measures is to remove the scale in the cooling system . Second , the cooling system should be filled with soft water . Third , keep the thermostat working normally . So install a water temperature gauge is necessary to the outboard boat marine .

The purpose of maintaining the optimal fuel supply advance angle for outboard engines is to enable full combustion of fuel . The oil supply advance angle of the outboard engine refers to the crankshaft angle from the moment when the fuel injection pump plunger starts to supply oil to the moment when the piston reaches the top dead center . Therefore , the fuel supply advance angle can be achieved by changing the phase of the crankshaft and camshaft . The rule is that when the camshaft is ahead of the crankshaft , the oil supply is advanced . Otherwise , it will lag .

There are 9 main reasons for high water temperature of outboard boat marine diesel engine. The diesel engine used for construction machinery generally has a high working temperature. Filling antifreeze can ensure its high boiling point and reduce scale in the cooling system . If any air in the cooling system is not discharged or the coolant is not replenished in time, the cooling performance will be reduced and the coolant temperature will be increased . Remove the air from the cooling system. Maybe the indication of the water temperature gauge is incorrect . Including : water temperature sensor is damaged; The circuit is grounded or the indicator fails , resulting in false alarm . At this time , the surface thermometer can be used to measure the temperature at the water temperature sensor and observe whether the indication of the water temperature gauge (warning light) is consistent with the actual temperature .
