<Special Feature> Internal Combustion Engines Aim for Ultimate Low Loss
Japan's world-class engine technology is the result of the steady efforts of all the engineers involved.
Efforts are being made day and night to achieve a loss reduction of 0.1%. We have planned this special feature to convey to our readers the efforts of engineers who firmly support this top-of-the-line engine technology and aim for even greater heights.
This special feature introduces specialized articles that support Japanese engine technology, such as new engines aimed at reducing loss, friction loss reduction, wall heat loss reduction, and exhaust resistance reduction.
Please have a look.
The Journal of Society of Automotive Engineers of Japan is published in electronic format. Please read it on your PC, tablet, or smartphone.
