Description
Technical Field
[0001] The utility model relates to the technical field of diesel generator sets, in particular to an emergency generator in high-cold areas. Background Art
[0002] Alpine areas refer to extremely cold climate zones due to high altitudes or high latitudes. Low temperatures will increase the viscosity of engine oil and fuel, deteriorate fluidity, and increase friction resistance inside the engine. The starting motor requires greater torque to drive the engine, which increases the difficulty of starting. Some metal and non-metallic materials may become brittle under alpine conditions and are prone to cracks or damage, affecting the structural strength and sealing performance of the generator. Low temperatures will worsen the atomization effect of the fuel and cause uneven mixing with air, resulting in incomplete combustion and reducing the power output and thermal efficiency of the engine.
