摘要： A compression ignition engine (10) has a control system (24) for processing data, one or more cylinders (16), a fueling system (18), and a variable valve actuation mechanism (20). Control system (24) develops both fueling data for fueling the engine and timing data representing time during the engine cycle for intake valve closure to a cylinder that will endow the cylinder with an effective compression ratio (ECR) appropriate to current engine operation for causing auto-ignition to occur near or at top dead center in the engine cycle. During a compression upstroke, the cylinder is fueled according to the fueling data and intake valve closure for the cylinder is performed according to the timing data. This creates an air-fuel mixture that is increasingly compressed to the point of auto-ignition near or at top dead center.

摘要： A mechanism (40) for enabling an engine cylinder valve (18) to close at various times during engine cycles has a hydraulic actuator (58) and a control valve (60) controlling the hydraulic actuator a) to constrain a pivot axis of a valve rocker (52) against relocation while the cylinder valve is being forced increasingly open, and b) to release the constraint after the cylinder valve has been forced open for enabling the pivot axis to relocate so that the intake valve can close early thereby providing early IVC. A hydraulic snubber (64) snubs closing motion of the cylinder valve through a scheduling geometry to a hydraulic accumulator (62). The control valve opens to the accumulator to allow the rocker pivot axis to relocate and provide early IVC and closes to return the pivot axis to a location that doesn't provide early IVC.

摘要： A premixed charge of air and a low reactivity fuel is created in a combustion chamber space by the time at which a piston comes substantially to top dead center at which time a high reactivity fuel is directly injected into a central zone of the combustion chamber space which is bounded partially by a central bowl cavity in the piston head which is itself surrounded by an upright intermediate wall. The high reactivity fuel combusts by conventional diesel combustion and creates a flame front which propagates into an outer zone of the combustion chamber space which is bounded partially by the upright intermediate wall and an outer bowl cavity in the piston head to initiate combustion of the premixed air-fuel charge in the outer zone of the combustion chamber space.

摘要： In a compression ignition multi-fuel engine employing both port/intake manifold injection of fuel and in-cylinder injection of fuel, the recirculation of exhaust gas to the engine induction system is used to control the temperature and to set the reactivity of an air/fuel charge introduced to the engine for combustion. Fuel directly injected during compression of the charge controls ignition. A variable valve actuator for opening and closing an intake valve extends control over charge pressure and temperature to extend suppression of auto-ignition of the charge. Fuel injection strategy and variable valve actuation are subject to a control strategy to extend the benefits of premixed combustion.

摘要： A method for controlling fuel injection timing into a cylinder of an internal combustion engine having an internal control system based on ignition delay correlation wherein intake manifold pressure and oxygen concentration values are compared to steady state values of manifold pressure and oxygen concentration of a particular indicated torque set-point and engine speed. Comparing intake manifold pressure and oxygen concentration to steady state reference values further comprises experimentally determining exponential factors for intake manifold pressure factor and oxygen concentration factors. A multiplier for intake manifold pressure and oxygen concentration is determined taking into consideration the exponential factors for manifold pressure and oxygen concentration. An equation for correlation ignition delay is used to determine optional SOI timing.

摘要： Engine includes an air induction sub-system for delivery of air to each cylinder. A lowpressure fuel injector injects a low reactivity fuel into the sub-system. An exhaust gas recirculation line connects exhaust gas purged from the cylinders back to the sub-system. An exhaust gas cooler cools recirculated gas in the exhaust gas recirculation line. The quantity of exhaust gas recirculated is controlled and the recirculated gas provides dilution and temperature control of the charge to suppress auto-ignition of the charge in the cylinder. A high pressure fuel injector injects a high reactivity fuel in the compression stroke for auto ignition and to initiate combustion of the charge. A variable valve actuator controls compression ratio and cylinder peak temperature. Boost is provided in air induction sub-system to assure combustion to stoichiometric levels.

摘要： When a high-pressure compressor stage operates in an efficient operating zone defined on a compressor performance to one side of an optimum performance line that is spaced from but generally parallel to a choke limit line, the turbocharger is controlled by closed-loop control of vanes of the high-pressure turbine stage while a by-pass around the high-pressure turbine stage is kept closed. When the high-pressure compressor stage operates in a zone between the optimum performance line and the choke limit line, the vanes of the high-pressure turbine stage are increasingly opened as operation of the high-pressure compressor stage increasingly approaches the choke limit line. When the vanes have been maximally opened and the high-pressure compressor stage has become unable to provide sufficient boost, the high-pressure turbine by-pass is opened to begin routing exhaust flow to a low-pressure turbine that operates a low-pressure compressor stage, thereby avoiding choking of the charge air flow by the high-pressure compressor stage.
