摘要:
In certain embodiments, there is provided a method of operating a turbocharged system including injecting a first quantity of fuel into an engine cylinder at a first predetermined time during a second half of a compression stroke before a piston of the engine cylinder reaches top dead center of the compression stroke. The method further includes injecting a second quantity of fuel into the engine cylinder at a second predetermined time after the first predetermined time when the piston is advanced by a predetermined advance value before the piston reaches the top dead center of the compression stroke.

System and method for supplying reductants to an emission treatment system. The system includes a fuel tank adapted to supply a premixed fuel stream that includes a primary component and a reductant component, and an engine in fluid communication with the fuel tank, wherein the engine is configured to create an emission. The engine includes an emission treatment system to treat the emission. The system also includes a separation system that includes a membrane with differential permeability for the reductant component relative to the primary component. The separation system is configured to receive at least a portion of the premixed fuel stream from the tank and to separate the premixed fuel stream into a first fraction and a second fraction. The first fraction includes a higher concentration of the reductant component than the second fraction, and the separation system is configured to supply the first fraction to the emission treatment system.
摘要:
Ignition of a main fuel in an internal combustion engine having at least one cylinder having a combustion chamber is accomplished by diverting a portion of the main fuel to a processing system; processing said portion of the main fuel to increase ignition sensitivity thereof and form a pilot fuel; introducing the main fuel into the combustion chamber; and introducing said pilot fuel to control ignition of the main fuel.
摘要:
A regenerative fuel cell is combined with a combustion engine such as a Pulse Detonation Engine (PDE) to create a closed-loop power generation system. Stored hydrogen and oxygen are used by the regenerative fuel cell, and by the combustion engine, in which the reaction of the hydrogen and oxygen produces water in the gas phase (steam). The steam is used to generate work from a turbine shaft, which is used to drive a propulsion system for the marine vessel. After the steam passes through the turbine, the steam is cooled back to liquid water by a condenser, and stored with the water produced by the regenerative fuel cell. The stored water can be converted back into hydrogen and oxygen by using electrical power external to the closed-loop system. After regeneration of the water into hydrogen and oxygen, the closed-loop power system would be ready for operation again.

A system and method for control of a fluid flow. The system includes an array of interdependent fluidic actuators, each including a chamber, a flow control port, and opposite side walls configured to expand apart and contract together to flow a control fluid through the flow control port in response to an input, wherein adjacent actuators in the array of interdependent fluidic actuators are integrally coupled together via a common side wall of the opposite side walls.
