Owing to space constraints, this paper introduced only NIRVANA injection screw air compressor characteristic.

Influence is described on engine performance of atmosphere temperature and air compressor characteristic by a serious of matching test between turbocharger and D6114 diesel engine.

And the capacities of compressor could be selected by on-off switch along with the change of burthen of evaporator, which is a main characteristic of the central refrigeration system model.
