This thesis analyzes the types and art trait of solar-assisted heat pump water heater, the development trend of direct expansion solar-assisted heat pump water heater, makes a summary of these research results from six aspects. On the basis of these works and from the point of view of receiving optimum solar radiation , the thesis develops a novel design model of direct expansion solar-assisted heat pump water heater with a truncated cone collector/evaporator, theoretically analyzes the heat that the system can absorb, compares its ability with other two types of cylinder and flat plate ones, and calculates COP and EER with computer aids. The results show that a truncated cone direct expansion solar-assisted heat pump water heater can absorb not only more solar energy but heat energy in air. It takes on favorable thermal performance. Under the average day in February which is of the worst weather throughout the year in Kunming, the COP is about 4. 2, EER is about 2.9 . The heat absorbed by the system are more than those of the other systems. The system is very great in terms of saving

The effects of port injected n-heptane equivalence ratio and iso-octane direct injection timing are investigated experimentally and numerically. The results indicate that the combustion mode of iso-octane is dependant on the iso-octane direct injection timing corresponding to the stage of n-heptane HCCI combustion. In case of direct injection before the low temperature reaction of n-heptane, premixed combustion of the iso-octane occurs. In case of direct injection at the NTC period or the initial high temperature reaction stage of n-heptane, the iso-octane mainly undergoes premixed combustion.
