| 41 | High efficiency, reduced emissions internal combustion engine system, especially suitable for gaseous fuels | US10284402 | 2002-10-31 | US20040083715A1 | 2004-05-06 | Christopher R. Le Leux; Gerald Fischer |
| Internal combustion (nullICnull) engine system for high fuel conversion efficiency and low exhaust emissions, particularly although not exclusively with gaseous fuels. An IC engine operates at approximately stoichiometric (nullnull1) air/fuel mass ratios. A higher-than-normal compression ratio for typical stoichiometric operation is possible for the engine, due to the introduction of an inert (i.e., not chemically reactive in the combustion process) gas into the air/fuel mixture. The inert gas slows the combustion rate to avoid uncontrolled combustion rates and engine nullknock.null The elevated compression ratio yields higher fuel conversion efficiency. Stoichiometric air/fuel ratio permits catalytic processing of the exhaust gas stream to reduce CO, NOx, and HC emissions via a combination of non-selective catalytic reduction process. | ||||||

| In a purifier for removing particulates from an exhaust gas, a pressure difference, and a flow rate of the air supplied to the filter element is adjusted in such a manner that a difference between a pressure difference of an air across a substantially invariable air flow resistance before the air reaches a filter element collecting and storing the particulates therein and a reference pressure difference is a predetermined value, while heating the air. | ||||||

| A filter-cleaning apparatus utilizes pulsed air to remove matter collected on a first surface of a filter. Reverse flow loosens the material which is collected in a hopper on the upstream side of the filter. The collected matter may then be combusted in the hopper so that the amount of material collected is minimized. The pulses are directed at the filter with a controlled shape and time to optimize reverse pulsing. Pulsing occurs while the thermal exhaust flow continues so that operation of the engine is not interrupted. A number of valves may be utilized to clean one or more filters. | ||||||

| 60 | Exhaust gas purification device for an engine | US08523455 | 1995-09-05 | US06409973B1 | 2002-06-25 | Yukio Kinugasa; Toshifumi Takaoka; Kouhei Igarashi; Takaaki Itou |
| The exhaust gas purification device according to the present invention utilizes two NOx absorbents in order to remove NOx from the exhaust gas of an engine operated at a lean air-fuel ratio. The NOx absorbents are disposed, in series, in the exhaust passage of the engine and a nozzle for supplying a reducing agent is disposed in the exhaust passage at a position between the two NOx absorbents. Further, the device includes switching valves for changing the direction of the exhaust gas flow in the exhaust gas passage. When the switching valves are set to direct the exhaust gas flow to one direction, the exhaust gas first flows through one of the NOx absorbents (first NOx absorbent), and after passing through the first NOx absorbent, the reducing agent is supplied to the exhaust gas before it flows into the other NOx absorbent (second NOx absorbent). Thus, the first NOx absorbent absorbs NOx in the exhaust gas, and the NOx absorbed by the second NOabsorbent is released from the second NOx absorbent. When the switching valves are switched, the exhaust gas flows in the opposite direction, and flows through the second NOx absorbent and the first NOx absorbent in this order. In this case, the second NOx absorbent absorbs NOx in the exhaust gas, and the NOx absorbed by the first NOx absorbent is released and reduced to N2. Therefore, by reversing the direction of the exhaust gas periodically, the absorbing operation of NOx and releasing/reducing operation of NOx are performed by two NOx absorbents alternately. Thus, it becomes possible to remove NOx in the exhaust gas continuously while the NOx absorbents are prevented from being saturated by the absorbed NOx. | ||||||
