Study on the use of alternative fuel made from waste vegetable oil in the diesel engine

As a useful alternative fuel, vegetable oil is a kind of continuous renewed energy sources made from photosynthesis. In the paper, a performance comparison experiment of two kinds of fuel, alternative fuel made from waste vegetable oil and No.0 diesel oil, was conducted in the small type of diesel engine. Results showed that the alternative fuel is fit for the diesel engine. Compared with diesel oil, in the export power of the engine, the WVO is much at one (only reduced 2%), and fuel consumption increased 6%∼12%, exhaust gas temperature decreased 20 °C, CO2, CO, HC concentration emission reduced 10%∼15%,10%∼18%,47% respectively. The theory on searching for alternative fuel using in diesel engine was also provided.

Design of control system for testing platform of soil-bin for agricultural machine based on PLC

Soil-bin provides a stable platform for the design and research of agricultural machine. An automatic controlling system was developed in order to improve the degree of automation. Industrial Control Computer and PLC (Programmable Logic Controller) were taken as the core control of the system. The system integrated kinds of techniques including variable frequency adjustable speed system, PXI bus technique, Lab View, image processing, etc. A Research on Scheme of control system was introduced. The function, basic components, Protection and Anti-interference Measures were discussed.
