Comparisons of Combustion Characteristics of Biodiesels in a High Speed Direct Injection Diesel Engine 2008-01-1638
A modified KIVA code is used to simulate the operation of a small bore HSDI engine with biodiesel from various sources. Genetic modified soybean biodiesel has very similarly combustion characteristics with soybean biodiesel, albeit less NOx. Yellow grease biodiesel burns in a similar manner as regular diesel with less NOx. All types of biodiesel show longer ignition delay but faster combustion, except after TDC injection, where biodiesel exhibits some diffusion combustion. Delaying injection is an effective way to reduce NOx emission. Over 90% of reduction in NOx is observed when fuel injection is delayed from 335° to 363°.
