“…Typical diesel particulate consists mainly of a carbonaceous core (soot formed during combustion), adsorbed compounds such as unburnt and partially oxygenated hydrocarbons, sulfates (due to the oxidation of the sulfur contained in the fuel), and metal oxides (Huehn and Sauerteig, 1989;Moser et al, 1990). The solid part and the adsorbed hydrocarbons readily react with oxygen present in the exhaust gas at sufficiently high temperatures (over 500°C).…”

“…For example, one could refer to the full flow regenerable, burner assisted trap system described in Huehn and Sauerteig (1989). The principle of operation of trap protection in this class of systems relies upon a compressor that is capable of sustaining sufficiently high flow rate through the trap even at idle conditions.…”

Comprehensive tests were performed on an on-road vehicle in cooperation with the Los Angeles County Metropolitan Transit Authority emissions test facility. All tests were with a transient chassis dynamometer. Tests included both a double arterial cycle of 768 s duration and an EPA heavy duty vehicle cycle of 1,060 s duration. The test vehicle was a 1994 pickup truck with a 5.9-L turbocharged and intercooled, direct injection diesel engine. Rapeseed methyl (RME) and ethyl esters (REE) and blends were compared with low sulfur diesel control fuel. Emissions data includes all regulated emissions: hydrocarbons (HC), carbon monoxide (CO), carbon dioxide (CO2), oxides of nitrogen (NOx), and particulate matter (PM). In these tests the average of 100% RME and 100% REE reduced HC (52.4%), CO (47.6%), NOx (10.0%), and increases in CO2 (0.9%) and PM (9.9%) compared to the diesel control fuel. Also, 100% REE reduced HC (8.7%), CO (4.3%), and NOx (3.4%) compared to 100% RME.

Heavy-duty diesel engine particulate matter (PM) emissions must be reduced from 0.1 to 0.01 grams per brake horsepower-hour by 2007 due to EPA regulations. A catalyzed particulate filter (CPF) is used to capture PM in the exhaust stream, but as PM accumulates in the CPF, exhaust flow is restricted resulting in reduced horsepower and increased fuel consumption. PM must therefore be burned off, referred to as CPF regeneration. Unfortunately, nominal exhaust temperatures are not always high enough to cause stable self-regeneration when needed. One promising method for active CPF regeneration is to inject fuel into the exhaust stream upstream of an oxidation catalytic converter (OCC). The chemical energy released during the oxidation of the fuel in the OCC raises the exhaust temperature and allows regeneration. This approach facilitates active control of the regeneration process so that the CPF can be operated in a sufficiently clean state to maintain engine performance and fuel economy. Development of active regeneration control strategies is challenging since a balance must be struck between fuel consumption for the regeneration process, keeping backpressure low by burning off PM, and maintaining regeneration stability.
