ment direction. The Council consists of representatives from the NMAs, NMGs and CMs and is responsible for the technical, financial and administrative policy of CIMAC. Briefly discuss the importance of CIMAC in the advancement of propulsion technologies. CIMAC provides forum for tech- nical interchange with all parties con- cerned with piston engines and gas tur- bines. The organization promotes the development of combustion engines and their applications. Congresses are held every three years and that activity has been ranked very important and valu- able for delegates (engine manufactur- ers, users, scientists etc.). The Working Groups are established by the Council to prepare recommendations and actual reports on subjects of combustion engine technologies. Some examples of working areas will be: Emissions, Fuels, Automation, Classification, Lubrication, Users etc. The activity will give direct benefits to manufacturers and engine users. What are the top three or four issues that have, in your opinion, had the most significant impact in driving marine propulsion development? 1. The rising fuel oil prises during 7' and 8' speeded up the engine effi- ciency development and development of heavy fuel engines dramatically; 2. Ship sizes have shown tendency for tremendous growth and that has cre- ated the market for largest two-strokers and trend is continuing; 3. Customer need for smokeless oper- ation in cruise business initiated the fast development of 4-stroke common rail engines; 4. The emission legislation has been one of the main driver to develop clean engines. What technologies do you count as having the most significant positive impact on marine propulsion in the last decade? Focus on the environment has encouraged the development of no
