Evaluation Of A Two Stroke Compressed Natural Gas Mixer Design By Simulation And Experimental Techniques

Natural gas is a viable alternative fuel that is able to reduce tailpipe emission, most notably in two stroke engines it is available in compressed form or Compressed Natural Gas (CNG) for easy storage. The excessive by-products of two-stroke engine combustion; normally due to inefficient combustion...
