III. Advantages of Diesel Engine Generator
The core advantages of diesel engine generators lie in their high power, low cost, and durability, making them a reliable choice for heavy loads and long hours of operation.
1. Diesel engine generator provide strong power and high overload capacity
Thanks to their high compression ratio, diesel engines naturally produce high torque. They have far superior ability to start up and power high-demand equipment (such as motors and compressors) compared to gasoline engines of the same power, making them ideal for harsh environments like construction sites and mines.
2. Diesel engine generator is economical and have low operating costs
Diesel fuel has a high energy density, making it more fuel-efficient. Additionally, diesel engines lack an ignition system, have simpler structures, and generally lower failure rates. All of this directly helps reduce long-term fuel and maintenance costs.
3. Diesel engine generators are robust and highly reliable
Diesel engine generators are designed to withstand intensive work, with more durable core components. Moreover, they use compression ignition rather than spark plugs, which are prone to wear, giving them a longer lifespan and higher availability.
IV. Precautions for Using Diesel Engine Generator in Cold Weather
1. Diesel Engine Generator Oil Selection and Handling
Change oil grade: You need to use the winter diesel grade corresponding to the lowest local temperature (for example, No. -10, No. -20). This is fundamental to prevent diesel from gelling and clogging the filter.
Add anti-gelling additive: If there's no time to change the oil, be sure to add a proper diesel anti-gel to the tank, which can effectively lower the cold filter plugging point.
My recommendation: Before winter begins, completely empty the tank and replace it with winter diesel. This is the most reliable approach.
2. Preparations and Operations Before Starting a Diesel Engine Generator
Preheating: Most modern diesel engines have glow plug functions. Before starting, turn the key to the "ON" position and wait for the preheating indicator to turn off (usually 10-20 seconds) to raise the cylinder temperature.
Gentle start: Do not hold the key continuously when starting. Each start attempt should not exceed 10 seconds. If it doesn't start, wait 30 seconds before trying again to protect the battery and starter.
Check the battery: Cold temperatures significantly reduce battery performance. Ensure the battery is fully charged and the terminals are secure and free of corrosion.
3. Operation and Storage Details of Diesel Engine Generator
Warm up slowly: After starting, do not immediately apply a heavy load. Let the diesel engine generator run without load or under a low load for 5-10 minutes to increase the oil temperature and lubricate all components.
Storage location: Whenever possible, store the diesel generator indoors or in a sheltered location, which can significantly reduce the effects of low temperatures.
Backup plan: If the environment is extremely cold, consider installing an engine block heater. This ensures the generator can start quickly in extremely cold conditions.
V. Precautions for Preventing Freezing of Diesel Engine Generator in Cold Weather
1. Use of antifreeze for diesel engine generator:
Check the freezing point: Use antifreeze coolant and ensure that its freezing point is lower than the historical lowest temperature in your area (recommended -25°C or lower).
Do not use water: If water has been added to the cooling system, it must be drained and replaced with proper antifreeze; otherwise, freezing can crack the engine block, causing devastating damage.
2. Diesel: Preventing solidification is of utmost importance
Switch to winter diesel: Depending on the local lowest temperature, diesel engine generators should be promptly switched to the appropriate grade of winter diesel (such as -10 or -20), which is fundamental to preventing diesel wax formation and clogging of filters and fuel lines.
Add anti-gel additive: Add a proper diesel anti-gel additive to the fuel tank as a double assurance along with changing to winter diesel.
3. Diesel generator engine oil and battery: Ensure smooth startup
Switch to winter engine oil: Check and replace with low-viscosity winter engine oil (such as 5W-30) to ensure that the diesel engine generator oil can quickly reach all lubrication points during cold start.
Maintain battery charge: Low temperatures significantly reduce battery capacity. Ensure the battery is fully charged, and the terminals are tightly connected and free of corrosion.
VI. Q&A on Diesel Engine Generator Knowledge
1. How does a diesel engine generator work?
Four-stroke cycle: Intake (drawing in air) → Compression (piston compresses air, raising its temperature) → Power (fuel injection, compression ignition generates power) → Electricity generation (kinetic energy is ultimately converted into electrical energy).
2. What is parallel operation of diesel engine generators?
Multiple diesel engine generators are connected through a parallel cabinet to operate synchronously to meet higher load demands, commonly used in large projects.
3. How should a diesel engine generator be maintained when not in use?
Drain the liquids from the diesel engine generator's water tank, fuel tank, and fuel lines, or fill them and add a stabilizer, then store the generator in a dry place.
VII. Applications of Diesel Engine Generator
1. Diesel Engine Generator as Backup Power
In hospitals, data centers, financial centers, airports, and commercial buildings, they serve as emergency power sources, automatically starting the moment the main power goes out, ensuring that critical operations and lifeline systems continue without interruption.
2. Diesel Engine Generator for Production and Construction
In remote mines, outdoor construction sites, and large-scale events, they act as the main power source, providing continuous power to machinery, lighting systems, and essential facilities.
3. Diesel Engine Generators as Mobile Power Stations
Integrated as vehicle-mounted power sources in specialized vehicles for communication, command, and inspection, they ensure that these mobile units can operate independently anywhere.
4. Remote Areas
For remote islands, grazing areas, or exploration camps, they serve as a regular power source and are the primary electricity provider for local production and daily life.
The value of diesel engine generators lies in their reliability and independence. They are not picky about the environment, always ready, and provide a dependable solution for dealing with power uncertainties.
