During high-load operation of an engine, fuel for initial slow-burning combustion and premixed combustion is injected into a combustion chamber by continuous fuel injection, then fuel injection is paused, and fuel for diffusion combustion is injected after a predetermined interval has elapsed. Also, the fuel injection amount in the continuous fuel injection is set higher than the fuel injection amount for diffusion combustion. A spray autointerference cooling effect is achieved by the continuous fuel injection, thus promoting ignition delay so as to increase the proportion of premixed combustion, thereby suppressing the production of smoke. This enables high-volume EGR to be performed, thus enabling reducing the amount of NOx produced.

Engine combustion control at low loads via fuel reactivity stratification

Номер: US20120247421A1
Автор: Derek A. Splitter, Reed M. Hanson, Rolf Deneys Reitz, Sage L. Kokjohn
Принадлежит: Individual

A compression ignition (diesel) engine uses two or more fuel charges during a combustion cycle, with the fuel charges having two or more reactivities (e.g., different cetane numbers), in order to control the timing and duration of combustion. By appropriately choosing the reactivities of the charges, their relative amounts, and their timing, combustion can be tailored to achieve optimal power output (and thus fuel efficiency), at controlled temperatures (and thus controlled NOx), and with controlled equivalence ratios (and thus controlled soot). At low load and no load (idling) conditions, the aforementioned results are attained by restricting airflow to the combustion chamber during the intake stroke (as by throttling the incoming air at or prior to the combustion chamber's intake port) so that the cylinder air pressure is below ambient pressure at the start of the compression stroke.

Rotary type stirling engine for green growth

Номер: US20130036732A1
Автор: Gook Sun Shin
Принадлежит: Individual

The present invention relates to a Stirling engine in which power is generated using a variation in pressure generated by continuously performing periodical heating and cooling operations when a heat transfer medium is stored in a sealed inner space. The Stirling engine generates power for rotating an output shaft ( 12 ) through the expansion and contraction of the heat transfer medium sealed and received in a space partitioned by a baffle ( 40 ) within an inner space ( 21 ) of a housing ( 20 ). Thus, when compared to the prior art, the Stirling engine of the present invention may be more easily manufactured. Also, the heat transfer medium for generating power may be easily managed, maintained, and repaired. In addition, since the heat circulation structure is simple, the Stirling engine of the present invention can achieve relatively higher thermal efficiency than those of the prior art.

Imbalance re-synchronization control systems and methods

Номер: US20130060449A1
Автор: Andrew P. Bagnasco, Ian J. Mac Ewen, Scott Jeffrey, Steven Ward Majors
Принадлежит: GM GLOBAL TECHNOLOGY OPERATIONS LLC

Fueling to one cylinder of an engine is selectively adjusted based on a correction associated with the cylinder. An instability module increments a counter value when the correction is equal to one of a first predetermined value and a second predetermined value and was previously equal to the other one of the first and second predetermined values. The instability module selectively generates a first indicator based on the counter value. A variance of imbalance values can be determined based on samples of an exhaust gas oxygen signal. Two variances are determined: one variance with adjustment based on the correction, one without adjustment based on the correction. A variance checking module selectively generates a second indicator based on the first and second variances. A re-synchronization module re-synchronizes the imbalance values with the cylinders, respectively, in response to generation of the first indicator and/or the second indicator.

METHOD FOR OPERATING A COMBUSTION ENGINE WHEN CHANGING FROM FULL ENGINE OPERATION TO PARTIAL ENGINE OPERATION

Номер: US20130085656A1
Автор: Delcour Thierry, GRUNWALD Oliver, Koehler Armin
Принадлежит: Audi AG

In a combustion engine, combustion chamber-specific deviations can be equalized by associating a specific adjustable air-fuel ratio with the individual combustion chambers. When changing from full engine operation to partial engine operation, the associated air-fuel ratios do not always remain optimal. A new air-fuel ratio, which is adjusted immediately when changing from full engine operation to partial engine operation, is then associated with the combustion chambers of a subgroup of combustion chambers to which an air-fuel mixture is applied in partial engine operation. The new individual air-fuel ratios can be easily computed, in particular, from the individual air-fuel ratios associated with full engine operation. 1. A method for operating a combustion engine having a plurality of combustion chambers , comprising the steps of:applying an air-fuel mixture to all combustion chambers for full engine operation,associating an individual air-fuel ratio with each combustion chamber for full engine operation,applying the air-fuel mixture to only a subgroup of the combustion chambers for partial engine operation, andassociating a new individual air-fuel ratio with the combustion chambers of the subgroup for partial engine operation, wherein the new individual air-fuel ratio is adjusted immediately when changing from full engine operation to partial engine operation.2. The method of claim 1 , wherein the new individual air-fuel ratio is computed based on the individual air-fuel ratios for full engine operation associated with at least the combustion chambers of the subgroup.3.
