Investigation of Low Temperature Combustion With Hydrogen Addition to Intake Gas and High Rate EGR
Published September 29, 2010 by Society of Automotive Engineers of Japan in Japan
This study experimentally investigated low temperature diesel combustion with small amount of hydrogen added to the intake air at high EGR rate. If EGR rate is high, combustion temperature and NO emission is low. Ignition delay is prolonged by high rate EGR and hydrogen addition. Smoke emission decreases by ignition prolongation and replacement of diesel fuel by hydrogen. The present study tried to simultaneously decrease NO and smoke emission by low temperature combustion with hydrogen addition and EGR at high load condition.
