摘要： A method of operating an engine system should produce relatively low concentrations of various emissions without compromising a desired power output of the system. In order to operate an engine system of the present disclosure, a predetermined total amount of fuel injected into at least one combustion chamber is apportioned into at least a first amount and a second amount of fuel. The first amount of fuel is injected into the at least one combustion chamber during non-auto ignition conditions. The second amount of fuel is injected into the at least one combustion chamber during auto-ignition conditions. When the engine system is in a mid-low engine load range, the second amount of fuel is one of equal to or less than 15% of the predetermined total amount of fuel. When the engine system is in a high engine load range, the second amount of fuel is greater than 15% of the predetermined total amount of fuel.

摘要： A method of operating an internal combustion engine is provided. The method includes injecting a first fuel charge into at least one cylinder of the engine. The method further includes determining a value indicative of at least one of a cylinder pressure and a rate of change in cylinder pressure. The method further includes injecting a second fuel charge into the at least one cylinder, upon the occurrence of a predetermined contingency, which may be a determined cylinder pressure or rate in change thereof exceeding a predetermined threshold. An internal combustion engine is further provided, including an electronic controller having a control algorithm. The control algorithm includes software for determining a value indicative of at least one of a cylinder pressure and a rate of change in cylinder pressure of at least one cylinder of the engine. The control algorithm further includes logic for transitioning a fuel injector of the engine between modes, based upon the occurrence of a predetermined contingency, which may be the determined value.

摘要： A piston for an internal combustion engine is disclosed. The piston has a piston crown with a face having an interior annular edge. The piston also has first piston bowl recessed within the face of the piston crown. The first piston bowl has a bottom surface and an outer wall. A line extending from the interior annular edge of the face and tangent with the outer wall forms an interior angle greater than 90 degrees with the face of the piston. The piston also has a second piston bowl that is centrally located and has an upper edge located below a face of the piston crown.

摘要： Often NOx selective catalysts that use ammonia to reduce NOx within exhaust to a harmless gas require on-board storage of ammonia which can be hazardous and inconvenient. In order to generate ammonia in exhaust, the present disclosure increases a NOx concentration in exhaust from at least one combustion chamber, at least in part, by injecting fuel in a predetermined increased NOx generation sequence that includes a first injection during non-auto ignition conditions and a second injection during auto ignition conditions. At least a portion of the NOx is converted to ammonia by passing at least a portion of the exhaust with the increased NOx concentration over an ammonia-producing catalyst.
摘要翻译：通常，使用氨将排气中的NOx减少到无害气体的NOx选择性催化剂需要板上存储氨，这可能是危险的和不方便的。为了在排气中产生氨，本发明至少部分地通过将燃料喷射在预定的增加的NOx生成顺序中来增加来自至少一个燃烧室的排气中的NOx浓度，所述增加的NOx生成顺序包括在非自动点火条件下的第一次喷射并在自动点火条件下进行第二次喷射。通过在排出氨的催化剂上使排气的至少一部分通过增加的NOx浓度而将至少一部分NOx转化为氨。
