Some Proposals to Low-Emission, High-Specific-Power Diesel Engine Equipped with CRT (*1) 2001-01-1256
CRT looks promising in achieving clean Diesel emission particularly PM, however, it presents two limits in exhaust gas temperature levels, i.e., at idling to low power region requiring emission temperature 260°C minimum, and at high power region 450°C maximum. These problems can only be solved by the proposed method under the currently available known technologies. At the lower power side, 260°C minimum, can be materialized by the use of “Exhaust Secondary Cam (ESC)”, throttling intake air and exhaust gas lines together with other means like reduction of number of cylinders in operation. At the high power side, 450°C maximum, will easily be cleared by “Hyperbrid supercharging system” invented by the author.
