One of the technical barriers of HCCI was controlling combustion timing,the HCCI two phases of combustion companied with two phases of heat release.

Combustion and heat release of diesel engine operating on both No.

The heat release calculation by external condensation of horizontal multitube, vibration check while media transversely flow over tube bundle, ensemble rigidity pipe bundle and connecting technology of tube and tube plate ware presented in this paper.

Simple method for determining gaining heat or losing heat in a thermodynamic process;

In this paper, we developed a handy way for determining gaining or losing heat in a thermodynamic process.

In this article two methods for determining gaining heat or losing heat in a thermodynamic process are given.

Experimental studies on the process of its heat discharge on the 10kW electric heat solid heat storage device are made and temperature distribution regulations in heat retaining mass under the different heating methods and control temperatures are obtained.

Experiments of heat discharge on the industrial simulation bedstand are conduced to study the performance of solidification process.

This article has discussed comprehensively straight line process in the p V graph of ideal gas with negative slope, and the endothermic and exothermic variations so as to understand the process completely and clearly.
