Blending pyrolitic oil (or Waste Plastic Disposal, called WPD for short) produced from household and industrial plastic wastes with bitumen, which is 70% (v) of orimulsion, reduces the viscosity of the oil. The experimental results indicated that, the WPD mixing ratio of 20% (v) reduces the bitumen's viscosity from more than 500 cSt to 20 cSt at 50℃. The blended oil has been applied to a small size high-speed single-acting 4 stroke diesel engine (14 kW, 2200rpm) without preheating the oil. The engine test with non-preheated blended bitumen has proved the possibility of WPD-blended bitumen as a fuel for diesel engines. In order to improve the engine performance the far-infrared filter has been tested. The engine test result has shown the good effect of the filter on the engine performance.
