    摘要： A method and apparatus generate turbulence and impact on soot rich zone within a burning fuel jet within a combustion chamber of an internal combustion engine. A reservoir accumulates charge and projects the charge into a combustion chamber and into and around the burning fuel directly injected into the combustion chamber. A ring or the fire deck define one or more reservoirs with an orifice for accumulating, directing and ejecting the charge. The method and apparatus are particularly beneficial when employed with gaseous fuels.

    摘要： This disclosure teaches a method of controlling a direct injection internal combustion engine and predicting the behaviour of a direct injection internal combustion engine. An estimation of initial cylinder pressure, air flow and EGR flow (if applicable) is used to establish a system that provides engine behaviour by integrating an injection module, combustion module and engine control module to provide data indicative of engine behaviour such as brake torque and power, air flow, EGR flow, cylinder pressure, brake specific fuel consumption, start of combustion, heat release rate, turbo-charger speed and other variables. These values can then be used to adjust commanded variables such as start of injection, commanded pulse width, rail pressure to meet operator demand. Also the output data can be used as a tool to determine how a conceptualised engine design will behave. This is particularly useful for gaseous-fueled internal combustion engines where cylinder pressure influences behaviour of injected gases in light of the fact that rail pressure and cylinder pressure are, generally, of a similar magnitude.

    摘要： An obstruction is employed in a combustion chamber of an internal combustion engine. The obstruction is located within the chamber to generate turbulence and break-up or disrupt the soot rich zone within a directly injected quantity of fuel that is burning. More specifically, a ring disrupts fuel jets directly injected into the combustion chamber that impact on or are influence by the ring. The ring can be suspended from the piston or from the fire deck. Post-type obstructions help generate turbulence and are also targeted at disrupting the soot rich zone of the burning fuel jets. A method involves disrupting the soot rich zone or reducing soot generated within the combustion chamber and increasing burn rate by impacting the fuel jets on an obstruction within the chamber.
