The miniaturized design of a gasoline generator

The key technical points for the miniaturized design of gasoline generators include the following aspects:

1. Theoretical Guidance in Practice: Comprehensively grasp the basic principles and structures of small gasoline engines to facilitate fault analysis and troubleshooting, especially for different models of engines, specific models require specific analysis.
2. Noise Control: The noise of gasoline generator sets exhibits a wide-frequency band spectrum characteristic, requiring the silencer to withstand high airflow speeds and be resistant to high temperatures, pressures, water, and humidity. In the design, micro-perforated plate composite silencers are often used, which have good absorption effects on medium and high-frequency noise.
3. Environmental Protection and Efficiency: With the increasing strictness of environmental regulations and consumer demand for noise control, modern gasoline generators pay more attention to efficiency and environmental protection in their design. Advanced combustion technologies and low-noise designs have been adopted, which reduce exhaust emissions and significantly lower operating noise, improving the user experience.
4. Intelligence and Sustainability: In the future, small household gasoline generators will focus more on intelligence and sustainability. By integrating intelligent control systems, generators can automatically adjust output power, improve fuel efficiency, and reduce carbon emissions. With the advancement of renewable energy technologies, generators will gradually transition to using biofuels or hybrid fuels to reduce dependence on fossil fuels, aligning with the development trend of green energy.
5. Control System Design: For small gasoline generator set systems, although the individual power is small, the power load variation of the equipment is large, leading to significant voltage fluctuations and speed fluctuations, affecting the performance indicators of the generator. A new control scheme is discussed in the design, using speed feedback and load current compensation control schemes to keep the generator’s output voltage stable under various load changes, and it has the characteristics of small overshoot and short stabilization time, which can greatly improve the power quality of the gasoline generator and enhance the product quality and competitiveness.
6. Electronic Governor Design: To improve the speed control performance of portable gasoline generators, an electronic governor has been developed using a digital signal controller. This governor can adjust the throttle position according to the load size and the actual speed of the gasoline engine, achieving closed-loop control of the gasoline engine speed through the PID algorithm.

These key points cover various aspects from basic theory to practical application, from environmental efficiency to intelligent control, and are the key technical elements to achieve the miniaturized design of gasoline generators.
