Abstract: A method of operating an engine comprises introducing into a cylinder volume a non-compression-combustible fuel, such as natural gas, a compression-combustible fuel, such as diesel, and an oxidant and mixing the components for greater than about 275 microseconds, prior to compression combusting the compression-combustible fuel. The mixing may be done such that the two fuels are at least partially homogenized in the cylinder volume. By mixing, or premixing, the two fuels prior to combustion, the compression-combustible fuel is then simultaneously combusted via compression at multiple ignition points in the volume. The second, non-compression-combustible fuel is ignited in response to the combustion of the first fuel. An engine that enables the various methods is also disclosed.

Abstract: A method of operating an internal combustion engine is provided. The method includes combusting a mixture of fresh air and fuel within multiple cylinders. The method also includes directing a first portion of exhaust gases into a first-stage turbine and a second stage turbine of a turbocharger for expanding the exhaust gases, directing a second portion of exhaust gases from the exhaust manifold via an exhaust channel bypassing the first-stage turbine and recirculating a third portion of exhaust gases into an intake manifold after mixing with fresh air. The method includes controlling at least one of: reducing a normal engine speed at each engine power setting while maintaining constant engine power level by increasing a fuel injection per cycle; concurrently increasing a flow rate of the third portion of exhaust gas during recirculation; and advancing a fuel injection timing for reducing emission levels that meets Tier 4 requirements. cuN 0 E co( ,,t LU -I cuu .x

Abstract: Ein Verfahren zum Betreiben eines Motors weist das Einbringen eines unverdichtet-brennbaren Kraftstoffs, wie z. B. Erdgas, eines verdichtet-brennbaren Kraftstoffs, wie z. B. Diesel, und eines Oxidationsmittels und die Vermischung der Komponenten für länger als ca. 275 Mikrosekunden vor einer Verdichtungsverbrennung des verdichtet-brennbaren Kraftstoffs auf. Die Vermischung kann so ausgeführt werden, dass die zwei Kraftstoffe wenigstens teilweise in dem Zylindervolumen homogenisiert werden. Durch Mischen oder Vorvermischen der zwei Kraftstoffe vor der Verbrennung wird der verdichtet-brennbare Kraftstoff gleichzeitig durch Verdichtung an mehreren Zündpunkten in dem Volumen verbrannt. Der zweite unverdichtet-brennbare Kraftstoff wird in Rektion auf die Verbrennung des ersten Kraftstoffs gezündet. Ein Motor, der die verschiedenen Verfahren ermöglicht, wird ebenfalls beschrieben.
