The Impact of Different Environments on Yuchai Diesel Generators

As one of the well-known domestic brand generators, Yuchai diesel generator set has been widely used in various industries as a self provided power source or backup power source. It has a wide range of applicable environments and can work normally under environmental conditions of -5 ° C~40 ° C and altitude below 2000 meters. However, when the environmental temperature is below the applicable range, users should take effective measures or use corresponding dedicated engines to ensure the normal operation of Yuchai generator set. So, what impact will different environmental conditions have on Yuchai diesel generator set? This article will take you to learn about Dingbo Electric Power.

1. When the ambient temperature is too low, the cylinder temperature will be very low, and the water vapor inside the cylinder is easy to condense on the cylinder wall. The sulfur dioxide generated during the combustion of Yuchai diesel generator will become a strong corrosive agent and adhere to the cylinder wall when it encounters the water condensed on the cylinder wall. Therefore, the surface of the cylinder wall will be strongly corroded, resulting in loose metal structure on its surface; When the cylinder liner and piston ring rub and scrape against each other, the loose metal on the surface of the corrosion layer will quickly wear off, or corrosion points and pits will appear on the working surface of the cylinder liner.

When the ambient atmospheric pressure decreases, the temperature increases, and the relative humidity increases, the amount of dry air sucked into the cylinder of the Yuchai diesel generator will decrease, and the power of the Yuchai diesel generator will decrease. On the contrary, the power of Yuchai diesel generator will increase.

3. Increased heat loss and fuel consumption

When the Yuchai diesel generator set operates at low temperatures, the cooling water takes away a large amount of heat energy from the cylinder, resulting in increased heat loss; The mixture cannot form and burn well, and fuel consumption will increase by 8% to 10%; After entering the cylinder in the form of droplets, the fuel will flush the lubricating oil film on the cylinder wall and infiltrate into the crankcase, increasing the wear of parts, diluting the lubricating oil in the oil pan, increasing fuel consumption, and reducing power output.

4. Deterioration of combustion and deterioration of overall performance

Some parts that expand due to heat are not expanded to their proper size due to low temperature, which affects the overall performance of the machine, such as large clearance between the piston and cylinder and poor sealing; The valve clearance is too large and is subject to rocker arm impact, which makes it difficult to start the Yuchai diesel generator set. When working in a diesel engine, the high temperature of the compressed gas is a necessary condition for ensuring fuel ignition. When the temperature of components such as cylinders and pistons decreases, it will cause a decrease in the final compression temperature, ignition delay, and deterioration of combustion conditions, resulting in incomplete fuel combustion, rough operation of the diesel generator, and exhaust smoke.

5. When the ambient temperature is too low, the temperature of the cooling water in the water tank is also too low, and the temperature of the lubricating oil decreases accordingly. The viscosity of the engine oil is higher when the temperature is low, and its flowability deteriorates. This not only increases the wear of the parts of the Yuchai diesel generator set, but also increases the mechanical power loss due to the increased resistance of the parts, resulting in a decrease in the output power of the Yuchai diesel generator set.

The impact of different temperatures on Yuchai diesel generator sets varies. If you need to use a diesel generator set in extreme weather conditions, you must operate it correctly, otherwise it may damage the unit and affect its performance.
