Studied of recycled fuel oil for diesel engine extracted from waste plastics disposals

In developed countries there are so many discarded plastic disposals from various kinds industry and cities. One of authors´ company (Ecology System) has developed a new recycling system and apparatus to liquefy these plastic disposals into fuel oils. These discarded plastics are melted and evaporated first, and their vapors are condensed and extracted after passing through various metal catalyzers for decomposition. The recycled oils are different one by one according to the kind of raw plastic, and generally it has high heating value with rather large density, and their total weight are about 60-80 % of raw plastics. The recycled oils are fed to diesel engines of several factories as a 30-40% blended fuels with gas oil. Recycling of plastics by this method will be a very good contribution to energy and environment of the Earth. In this paper it is shown that cracked PE (polyethylene) blending oil can be used for engine performance
