20080314363 | Actuated cool combustion emissions solution for auto-igniting internal combustion engine - Lower temperature combustion, which may lead to lower emissions, is accomplished by displacing air adjacent to a fuel injector nozzle. Initially, air is compressed in an engine cylinder by moving the engine piston toward top dead center. Air is displaced through a flow passage within the engine cylinder when the engine piston is in the vicinity of top dead center by moving an air displacement actuator. The air displacement actuator includes a member positioned in the combustion chamber that moves with respect to the engine housing and the piston when actuated. This movement causes air to flow through a flow passage, and fuel is injected into the turbulent compressed air flowing through the flow passage. The mixture of air and fuel are compression ignited in the engine cylinder after a brief ignition delay. Lower emissions may be achieved by bringing the air to the fuel prior to ignition, rather than attempting to bring the fuel to the air as in a typical compression ignition engine. | 12-25-2008 |

A volume change of the fuel in liquid phase in the fuel gallery can be compensated by a volume change of the fuel in gas phase or gas-liquid phase in the pressure chamber. Thus, the pressure pulsation in the fuel gallery is absorbed in the pressure chamber. | 01-07-2016 |
