Blending pyrolitic oil (or Waste Plastic Disposal, called WPD for short) produced from household and industrial plastic wastes with natural bitumen, which is 70% (v) of orimulsion, reduces the viscosity of the natural bitumen. The experimental results indicated that, the WPD mixing ratio of 20% (v) reduces the natural bitumen's viscosity from more than 500 cSt to 20 cSt at 50°C. 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 natural bitumen has proved the possibility of WPD-blended natural bitumen as a fuel for diesel engines. In order to improve the engine performance and exhaust characteristics, the far-infrared fuel filters have been tested. The engine test result has shown the effect of the far-infrared fuel filter in the aspect of enhancing the engine performance stability and reducing NOx and N<SUB>2</SUB>O emission.
