| Abstract: | For the sake of realizing compressive ignition of single fueled natural gas and aiming at the characteristics of high spontaneous combustion temperature of natural gas, the separated combustion chamber provided with low heat radiation structure was designed, meanwhile the heating device for the intake pipe air and the ceramic electro-thermal plug heating device inside the separation chamber were set up. The passage di mension of separation chamber, the heating temperature of intake pipe air and the relevant influence of the ceramic heat insu- lation coating of combustion chamber upon the compressive ignition process of natural gas were studied by experiment. |
