Recent Technology and Prospect of Reciprocating Hydrogen Fuelled Engines

Abstract

The characteristics of hydrogen have been reviewed to show that hydrogen is good as a fuel of automobiles. There are two mixture formations in hydrogen engines. One is external mixture. And the other one is internal mixture formation. These mixture formations show different characters in engine performance. By comparing the two mixture formations、 the author would like to show which one is better for automotive engines. Based on the result、 recent technologies and prospects have been discussed.
