Performance of CO2 enrich CNG in direct injection engine
This paper investigates the potential of utilizing the undeveloped natural gas fields in Malaysia with high carbon dioxide (CO2) content ranging from 28 to 87. For this experiment, various CO2 proportions by volume were added to pure natural gas as a way of simulating raw natural gas compositions in...
