Simultaneous reduction of nitric oxide and smoke opacity in TDI dual fuel engine fuelled with calophyllum-diesel blends and waste wood chip gas for modified inlet valve and injector nozzle geometry

The present paper briefly elaborates the influence of inlet valve masking (IVM) and nozzle hole configuration on performance, emission and combustion behaviour of a single cylinder water cooled turbo-charged engine fuelled with Calophyllum inophyllum as injected fuel and babul wood chip generated pr...
