การศึกษาตัวแปรที่มีผลต่อสมรรถนะการฉีดเชื้อเพลิงของหัวฉีดรถยนต์ที่ใช้น้ำมัน ไบโอดีเซล และ น้ำมันไพโรไลซิส

The purpose of this research is to study on variables affecting fuel injection performance of biodiesel fuel injection and pyrolysis fuel. To test for variables affecting the fuel injection performance of biodiesel fuel injectors and pyrolysis fuel. By experimenting and modeling using computer programs to compare results. Finally for to use the information in the design of the car nozzle to work well with Biodiesel and pyrolysis fuel. The tested fuels which are pyrolysis fuel Bio-diesel fuel and diesel fuel are tested by tester Anton Paar@ Stabinger Viscosmeter (model SVM 3000/G2) ASTM D341 standard. The result shown that the density of the fuel is increasing normally. However the viscosity of the diesel and biodiesel are strong increased whereas the reducing of temperature is unaffected to the pyrolysis fuel. The fuel injection performance test showed that the density and viscosity of fuel were the major variables that affected the injection performance of the fuel. In case of using pyrolysis oil Injection performance is trend to higher other fuels and cold conditions.
