| 20090165441 | Combustion engine with feedback gear/rotary pump input - A combustion engine, which is highly efficient, noiseless and lightweight, includes a combustion chamber without pistons. The combusted and expanded air exiting the combustion chamber flows into a displacement pump, such as a gear pump or radial vane pump. The displacement pump drives the load, and, in addition, another smaller displacement pump, which pressurizes fresh air and introduces same, via a feedback loop, into the combustion chamber. Gas or other burnable fuels are introduced in the combustion chamber, so that a continuous fuel burning will occur, after being ignited. The ratio of bigger to the smaller pump is influenced by the percentage of expansion of the air in the combustion chamber. Additional features could be implemented for optimization of performance of the combustion chamber, such as: spring loaded adjustable baffles within the chamber to create desired compression, meandering walls and protrusions in the feedback loop, and heating the air in the smaller pump prior to entry into the feedback loop. | 07-02-2009 |
| 20090173060 | EXHAUST GAS CONTROL APPARATUS - An exhaust gas control apparatus is provided for an internal combustion engine having at least two cylinders, a turbine, and an exhaust manifold collecting a flow of exhaust gases formed in each cylinder towards the turbine. The exhaust manifold has an inlet port connected to each cylinder and an output port upon which the turbine is secured. The exhaust gas control apparatus includes at least one seal positioned between two adjacent inlet ports, each seal being articulated relative to the exhaust manifold and being capable of sealing one of the two adjacent inlet ports to reduce the internal volume of the exhaust manifold available for the flow of exhaust gas. The apparatus of the invention makes it possible to reduce the internal volume of the exhaust manifold according to the engine cycle. By doing so, most of the kinetic energy of the exhaust gases is channelled towards the turbine; this is in contrast with a traditional exhaust manifold whereby a part of the kinetic and thermal energy of the exhaust gases is dissipated within the internal volume of all the inlet ports of the exhaust manifold. | 07-09-2009 |
| 20100186379 | EXHAUST GAS PURIFICATION APPARATUS FOR AN INTERNAL COMBUSTION ENGINE - An object of the present invention is to improve preferable promotion of the modification of reducing agent in a precatalyst in the case where the reducing agent is added through a reducing agent addition valve in order to supply the reducing agent to an exhaust gas purification catalyst. According to the present invention, one end of an exhaust passage in which an exhaust gas purification catalyst is provided is connected to an exhaust manifold, and a precatalyst and a reducing agent addition valve are provided in the exhaust manifold. The precatalyst is configured in such a way that the exhaust gas flows through the gap between the outer circumferential surface thereof and the inner wall surface of the exhaust manifold. The precatalyst and the reducing agent addition valve are arranged in such a way that the most part of the reducing agent added through the reducing agent addition valve flows into the precatalyst. | 07-29-2010 |
| 20100186380 | METHOD FOR REMOVING SOOT PARTICLES FROM AN EXHAUST GAS, ASSOCIATED COLLECTING ELEMENT AND SYSTEM - A method for removing soot particles from an exhaust gas of an internal combustion engine, especially of a diesel engine, includes feeding the exhaust gas through a collecting element through which the exhaust gas can pass freely but which is provided with a plurality of deflections and/or zones of swirl and calming or stabilization.
