During combustion phenomena in Petrol engines, combustion is accompanied by flame, producing a very high rate of pressure rise resulted in detonation. Incidence of knock remains a significant barrier to achieving optimum performance potential. Experimental results are presented of the knocking behavior of a number of common gaseous fuels that include methane, hydrogen, propane and carbon monoxide and their mixtures. Comparison with the corresponding performance with liquid fuels is also made. Guidelines for achieving extended knock free operation with these fuels are to be outlined in this...

The refrigeration load and capacity of the system fluctuates due to input conditions and change in ambient conditions. Since the capacity of the system is designed for maximum load conditions. During half load conditions, the capacity of the system is greater than the requirement. Hence it is necessary to control the capacity of the system to reduce the energy consumption and maintain the required design conditions. Automatic controls make the system to operate independently without skilled supervision and also maintain higher degree of accuracy in maintain the temperatures. The...

A numerical model is developed to simulate the steady state behaviour of a Domestic Refrigerator Evaporator controlled by a expansion valve. The liquid-vapour slip in the two-phase region of the evaporator is accounted for by a void fraction model. The Refrigerator is one of the most important and the biggest energy-consuming device. The selected Refrigerant mixtures are tested as potential short and mid-term substitutes for CFC12, HFC134a with some hydrocarbons (HC290) are considered as components of refrigerant mixtures but mineral oil is used for the analysis. HFC134a with HC 290 are used...
