EXHAUST GAS CLEANING SYSTEM FOR VEHICLE

Method of detecting a doser valve opening or closing event

A method of detecting a valve opening or closing event in a solenoid operated reductant injector valve comprises applying a voltage with a chopped waveform to the solenoid to actuate the valve. The resultant current through the solenoid is sampled at local maxima 13, 15, 17 and minima 14, 16. Values of the difference between local maxima and subsequent local minima or between local minima and subsequent local maxima are determined. A valve opening or closing event is determined based on the rate of change of the difference values. The valve opening or closing time may be determined from the rate of change. Valve opening and closing events are determined from a plot of values of the current at local maxima or local minima. The first or second derivatives of the plot may be compared to a threshold. The sampling times may be synchronised with the modulation signal with respect to the voltage drive.

Filtration and combustion process for carbon particulate matter from an internal combustion engine

The object of the invention is a filtration and combustion process for carbon particulate matter from an internal combustion engine. The process is characterized by the following steps: a rare earth or rare earth mixture derivative is introduced into the fuel at a concentration of 10 ppm to 500 ppm (by weight), and preferably of 20 ppm to 200 ppm; the soot produced by the internal combustion engine is collected on a filter, the temperature of the gases entering the filter being selected in the range of 100 ~C to 350 ~C; the soot is allowed to build up until a significant fraction or rate of incoming soot is balanced by the combustion of soot in the soot cake on the filter, and no regeneration is effected as long as the head loss caused by the soot does not exceed a preselected value and is not higher than 400 millibars. This invention is useful for organic synthesis.

Method and apparatus for reducing harmful emissions from a diesel engine by post combustion catalyst injection

Emissions of pollutants from diesel engines (10) are reduced by a regimen for catalytically treating engine exhaust and, preferably, also the combustion of the fuel. The balance point of a diesel trap (30) is reduced to permit more efficient regeneration, preferably self-regeneration, while also reducing emissions of carbon monoxide and hydrocarbons by a combination of mechanical devices and fuel additives. The regimen requires the introduction of from 0.05 to 1 ppm of a platinum group metal catalyst (based on the volume of fuel combusted) into the particulates, by introducing at least half of the platinum group metal catalyst (50) directly into the hot exhaust gases (52, 20). Preferably, the platinum group metal catalyst is employed with a combustible organic liquid to aid in either progressively loading the trap (30) with the combustible organics or to combust in the hot combustion gases to facilitate burning of the particulates on the trap (30) for more effective regeneration. The judicious selection and use of an auxiliary catalyst metal (e.g., copper), preferably adding at least half of its total to the fuel as a fuel additive, is a preferred part of the regimen to achieve the lowest trap balance point.
