摘要： A diesel engine and method for operating a diesel engine with exhaust after-treatment device regeneration capability are disclosed. The diesel engine may employ an exhaust after-treatment device such as a diesel particular filter to remove soot from the combustion gases exhausted by the engine. To regenerate the exhaust after-treatment device, the temperature of the exhaust gases is sufficiently raised by employing multiple compression and expansion strokes of the piston in certain engine cycles, with a combustion event associated with each pair of compression and expansion strokes. The engine may operate in a four stroke, one combustion cycle during conventional power operation, and switch to an enhanced combustion cycle during regeneration. The enhanced combustion cycle may include eight strokes with three combustion events. The engine may switch between cycles by using any selectively actuable valve actuator to prevent opening of the intake and exhaust valves during regeneration.
摘要翻译：公开了一种用于操作具有废气后处理装置再生能力的柴油发动机的柴油发动机和方法。柴油发动机可以采用诸如柴油特定过滤器的排气后处理装置来从发动机排出的燃烧气体中除去烟灰。为了再生排气后处理装置，通过在某些发动机循环中采用活塞的多次压缩和膨胀冲程，伴随着与每对压缩和膨胀冲程相关联的燃烧事件，废气的温度被充分地提高。发动机可以在常规动力操作期间在四冲程，一个燃烧循环中操作，并且在再生期间切换到增强的燃烧循环。增强的燃烧循环可以包括具有三个燃烧事件的八个冲程。发动机可以通过使用任何可选择性致动的阀致动器来在循环之间切换，以防止再生期间进气门和排气门的打开。

摘要： A control system (12) for an engine (10) having a combustion chamber (22) is disclosed. The control system may have a fuel injector (40) configured to selectively inject fuel into the combustion chamber, and a controller (54) in communication with the fuel injector. The controller may be configured to activate the fuel injector during a first compression stroke to initiate fuel injection in an amount and at a timing that results in a stratified lean air/fuel mixture within the combustion chamber during a first combustion event of a six- stroke cycle. The controller may also be configured to activate the fuel injector during a first power stroke to initiate fuel injection in an amount and at a timing that results in a homogenous lean air/fuel mixture within the combustion chamber during a second combustion event of the same six-stroke cycle.

摘要： In a multi-mode, 2-stroke/4-stroke internal combustion engine operation, by switching the engine stroke from 4-stroke operation to 2-stroke operation so that the combustion frequency is doubled, doubling of the engine power is achieved even at the same work output per cycle. In order to meet the demand of extremely high power, the engine operates in 4-stroke boosted SI operation transitioned from 2-stroke HCCI operation at pre-set level of power and crank speed requirements. By combining the multi-stroke (2- stroke HCCI and 4-stroke HCCI) and multi-mode operation (2-stroke HCCI and 4-stroke boosted SI operation), full load range and overall high efficiency with minimal NOx emission are achieved.

摘要： This ICE combines the advantages of a four-stroke engine and the power output of a two-stroke and air engines. The air charged from the high pressure receiver (1) is charged the engine through the electric valve (4) independently of the fuel and enables, due to a great difference in pressures, fast performance of the process eliminate intake and compression strokes which results in a two-stroke cycle operation. Depending on the degree of air reduction, the mode of operation of atmospheric or turbocharged engine can be achieved. Replacing of the mechanical exhaust valve (6) with the electric valve (7a, 7b) enables switching from two-stroke to four stroke mode of operation and vice versa only by the computer 2 instruction. Location of the fuel nozzle (5) directly in the compression chamber and its operation independently from the electric air valve (4) enable use of the petrol, gas and oil.

A first stroke mode for a first cylinder is selected and comprises at least a sequential deactive operation of the opening and the closing of a first intake valve and a first exhaust valve during at least two reciprocations of a first reciprocating piston. The first stroke mode is operated on the first cylinder, a second stroke mode is operated on a second cylinder, and a third stroke mode is operated on the remaining cylinders to meet or exceed a required torque output and to form a first aggregate of forcing function frequency profiles that comprises primary forcing function frequency profiles that are less than or approximate in amplitude and less than or approximate in frequency value to one of the respective baseline of primary forcing function frequency profiles.

摘要： Various methods and arrangements for improving fuel economy in decel fuel cut-off (DFCO) operation of an internal combustion engine are described. In one aspect, a catalytic converter bypass valve diverts the pumped air in DFCO mode from flowing through a catalytic converter. The diverted, pumped air may flow through a bypass line or be returned to the engine intake manifold through an exhaust gas recirculation return line. Another aspect of the invention relates to directing the diverted pumped air through an emission control device.

摘要： A method for exhaust temperature management in a multiple-cylinder, reciprocating-piston engine, comprising sensing a low temperature condition of the exhaust and implementing an increased heat output engine cycle pattern for the engine based on the sensed low temperature condition. The increased heat output engine cycle pattern comprises deactivating fuel injection to a first cylinder of the engine, the first cylinder comprising a piston reciprocating between top-dead-center and bottom-dead-center. Also, activating engine braking mode on the first cylinder by opening one or more valves when the piston is away from bottom-dead-center during a compression stroke. A second cylinder of the engine is fired in a combustion mode while the first cylinder is in engine braking mode.
