Partially pre-mixed auto-ignition of gasoline to attain low smoke and low NOx at high load in a compression ignition engine and comparison with a diesel fuel

A device for purifying the exhaust gas of an internal combustion engine is disclosed. The device has a particulate filter arranged in the exhaust system on which the trapped particulates are oxidized, and a reversing mechanism for reversing the exhaust gas upstream side and the exhaust gas downstream side of the particulate filter. The particulate filter has a trapping wall. The trapping wall has a first trapping surface and a second trapping surface. The reversing mechanism reverses the exhaust gas upstream side and the exhaust gas downstream side of the particulate filter so that the first trapping surface and the second trapping surface are used alternately to trap the particulates. The device can improve the amount of particulates that can be oxidized and removed on the particulate filter.

Feasibility Study of Ethanol Applications to A Direct Injection Gasoline Engine

Fischer-Tropsch Diesel (FTD) fuel is expected to be a promising clean diesel fuel in the future because of its characteristics of zero sulfur, zero aromatics and a high cetane number. However, the optimum fuel properties for diesel engines have not been realized. In this study, the effects of cetane number and distillation characteristics on engine-out PM emissions from a conventional direct injection diesel engine were investigated by using paraffinic fuels which were made to simulate FTD fuel. From the results of the vehicle exhaust emissions test and engine dynamometer test, it was found that the narrow distillation characteristics (which eliminates heavy hydrocarbon fraction) could reduce the soluble organic fraction (SOF) in PM emissions, and the excess high cetane number characteristic promoted the formation of insoluble organic fraction (ISOF). It is considered that shorter ignition delay due to the excessively high cetane number results in poor mixing of injected fuel and air in the combustion chamber. Future diesel engines are expected to lower the compression ratio and to require the fuels with high cetane number. However, in the case of conventional diesel, the results showed that moderate high cetane number and narrow distillation properties eliminating the heavy hydrocarbon fraction were desirable as the optimum FTD fuel.
