När temperaturen gradvis minskar, särskilt i kalla områden i höga höjder, blir det svårare att starta dieselgeneratorer på vintern .
Temperaturen inuti motorn sjunker kraftigt och oljeviskositeten ökar, vilket direkt påverkar dieselmotorns startprestanda .
We understand that diesel generator sets generate power by injecting diesel into the cylinder, where it mixes with high-pressure, low-temperature compressed air to form a high-temperature, high-pressure mixture that can ignite spontaneously. When the ambient temperature drops, the temperature in the combustion chamber also decreases, causing changes in the fit clearances of various components of the diesel engine. This increases the resistance moment required for starting. Additionally, diesel contains a certain amount of wax, which may precipitate at low temperatures and cause clogging of the filter, thereby affecting the normal supply of fuel. In this case, the temperature is referred to as the cold filter plugging point of diesel.
In the cold winter, the viscosity of diesel will increase, the fluidity will be weakened, and there may even be wax formation, which will cause the diesel to fail to flow, making it difficult to start the engine. In addition, during the start-up process, the lubricating oil and cooling water may also condense into a solid state due to the low temperature, thus losing the lubrication and cooling function, which may damage the motor .
The water jacket heater of the diesel generator set can maintain the engine at a certain temperature, so as to prevent the freezing and cracking of the generator set in winter.The heater enables the diesel engine to start quickly at low temperatures.The jacket heater can maintain the water temperature in the jacket of the unit at a set value (about 35℃) and indirectly heat the lubricating oil through heat conduction, därmed förhindra oljan från att kondensera .
I den hårda vintermiljön är därför den förvärmda motorn utan tvekan ett klokt val, som ger en stabil driftsbasis för dieselgeneratoruppsättningen och säkerställer den pålitliga starten av utrustningen vid ett kritiskt ögonblick .}
