Small Two-cyliner Gas Turbine Control System Design

In this paper a small two-cylinder gas engine for the study, natural gas engine electronic control system to carry out theoretical and experimental research aimed at identifying suitable ignition natural gas engines and speed control method and control system, ignition natural gas engines and speed control method and control system in China. For this paper, distributed power to promote a greater impact with gas engines, has an important significance.The first paper to 120 kilowatts power generation gas engine introduced supercharged gas engines overall control process, analysis of the gas engine to control the intake of different institutions in different ways, analysis of the key factors that affect the air-fuel ratio, to find a solution:According to different working conditions control the throttle opening, select the appropriate ignition timing to achieve optimal control.Next, the paper analyzes the idea of natural gas engine ignition control, to illustrate the problem, no description of the limited control of the ignition 2 cylinder engine, but rather focus on the calculation of the ignition advance angle, regardless of a few tanks, do the same method can be achieved control. For the throttle control is relatively simple, this is not too much narrative.Control ideas to sort out, the next step is to control the realization of ideas. The system according to the number of input and output signals and requirements, select the appropriate host controller, the power supply modules, input and output modules, each module of the microprocessor module hardware implementation are described in detail, and describes the relevant proceduresEngine debugging process is extremely complex, to facilitate on-site commissioning, this article describes applies to on-site debugging PC software, the software installation, use and impact of the engine block are described in detail, and provides on-site debugging data.Through the above analysis, this paper concluded that the design of the gas engine control system, either from theory or from practical work, the engine control can be achieved.
