The characterization of pyrolysis oil obtained from mixed waste plastics and its utilization in a compression ignition engine were investigated. chemical compositions physicochemical properties distilled plastic (WPO) crude (CWPO) analyzed. experiment was conducted with variable ratio diesel at various loads ratios to evaluate combustion characteristics, exhaust emissions, performance. experime...

At partial load, traditional automotive gasoline engines have high pumping losses due to the throttling of intake charge for load control. Variable Valve Timing (VVT) and introduction externally cooled EGR could reduce but only with a very limited effect. On other hand, in medium full range, engine cannot utilize compression ratio limitations knocking. A variable displacement, device which util...

Tremendous efforts have been devoted to study the complex phenomenon "knock in spark ignition engines. There is an increasing interest in providing some tools to study knock in simulated data. In the previous studies, engine cylinder pressure oscillation has been used to investigate knock. Unless those methods involved highly complex non-detailed chemical relations, the previous studies were de...
