Supercharged HCCI Engine: Prediction of Combustion Parameters at Varying Load and Speed
// Dvigatelestroyeniye. 2013. 3. P. 915.
Keywords: HCCI engine, working cycle, dimethyl ether, natural gas, combustion velocity, indicating parameters.

A new combustion model was offered. The model was used as a basis to develop a new method of analysis of HCCI engine combustion process, which would yield current values of heat release rate, heat transfer, and changes in working medium mass, volume and composition. Indicated parameters of combustion process in supercharged HCCI were calculated for varying load and speed values.

Engine Building Worldwide (Based On Papers Presented at CIMAC 2013)
// Dvigatelestroyeniye. 2013. 3. P. 3953.
Keywords: HERCULES scientific project, computer-aided design, ultimate engine, emission reduction limits, operating values' stability, emission reduction technologies, liquefied natural gas, dual fuel engines.

The paper in question presents preliminary results of HERCULES integrated project, carried out by major engine makers MAN and Wartsila partly funded by European Union. The project in general is targeted at evaluation of practical limits of emission reduction in transport and marine diesel engines by integration of various successful technologies, without compromising efficiency. Challenges arising from dual duel operation are considered, and solutions of problems involved are analyzed.
