Precautions for Operating Diesel Generators in Low-Temperature Environments

When using diesel generators in low-temperature regions, special measures must be taken regarding fuel, engine oil, batteries, and insulation, along with proper maintenance, to ensure normal startup and operation of the diesel engine. Specific precautions are as follows:

<!--[if !supportLists]-->1. <!--[endif]-->When starting the diesel generator, run it at a low to medium idle speed (approximately 1000–1200 rpm) for a period (typically 5–15 minutes, depending on temperature) to warm up the engine.

<!--[if !supportLists]-->2. <!--[endif]-->Based on the expected minimum ambient temperature, select diesel with a pour point at least 5–10°C lower than that temperature (e.g., 0#, -10#, -20#, -35#, etc.). Before switching to a lower-grade diesel or during sudden temperature drops, add a qualified diesel anti-gel additive in the appropriate proportion.

<!--[if !supportLists]-->3. <!--[endif]-->Ensure the proper concentration of coolant and the sealing integrity of the cooling system, and reasonably control the flow and temperature of the cooling system.

<!--[if !supportLists]-->4. <!--[endif]-->Regularly check the battery’s electrolyte level and charging status, and recharge or replace aged batteries as necessary. In extremely cold regions or after long periods of inactivity, consider removing the battery and storing it in a warm indoor space, reinstalling it before use.

<!--[if !supportLists]-->5. <!--[endif]-->If the diesel generator will be inactive for an extended period, drain the fuel from the fuel tank. Ensure all components of the generator are dry and clean, and store the unit in a dry, well-ventilated warehouse. Alternatively, install heating equipment to prevent rust or damage to the machinery
