摘要： The present invention relates to a method and apparatus for removing hydrocarbons from the exhaust stream of a diesel engine prior to cooling the exhaust for recycling through the intake manifold. A filter is used to remove hydrocarbon combustion products, including particulate matter, from the exhaust at a point after the exhaust gasses leave the exhaust manifold and before the exhaust gasses enter an exhaust gas cooler. Reduction of the hydrocarbon levels in the exhaust gasses slows or prevents buildup of hydrocarbon residue downstream of the filter, such as in the exhaust gas cooler, reducing the frequency of the requirement for cleaning or replacing the filter and effectively extending the life of the exhaust system.

摘要： A method of operating a spark ignition engine comprises introducing a fuel comprised of a water soluble organic compound and at least 30% by volume water mixed in a homogeneous charge air-fuel mixture. The air-fuel mixture is compressed in an engine having a compression ratio of at least about 16, with such compression ratios including the effective compression ratios arising from precompressing the intake air (e.g., turbocharging). The compressed air fuel mixture is then ignited by a spark or like controllable ignition source.
