摘要: Adding hydrogen to natural gas is a promising way improve the ignition stability and reduce greenhouse emissions of pilot-ignition direct-injection engines. Most previous studies concerning hydrogen-enriched engines are focused on spark-ignition The limited investigations addition in conducted by experimental method. Therefore, some detailed information in-cylinder combustion emission formation process left unknown. In this work, numerical simulations have been performed for engine based an integrated mechanism which capable describing chemical kinetics involving diesel, gas, hydrogen. Three-dimensional (3D) computational fluid dynamics were at different blend ratios explore effects whole mole f...
