摘要： A compression-ignition internal combustion engine includes a plurality of combustion chambers operating in a four-stroke combustion cycle and is configured to operate at a geometric compression ratio greater than 10:1. A method for operating a the engine includes forming a fuel/air charge by injecting fuel into each combustion chamber during a compression stroke, wherein the injection is completed prior to any combustion within the combustion chamber. The method further includes operating the engine to manage temperature of the fuel/air charge in the combustion chamber below an auto-ignition point of the fuel/air charge, and providing a spark discharge in the combustion chamber subsequent to injecting the fuel and in advance of the fuel/air charge achieving an auto-ignition temperature.

摘要： A method of optimizing combustion in a combustion chamber during operation of a fuel-injected internal combustion engine includes monitoring an operating condition of the internal combustion engine, and adjusting a protrusion depth of a fuel injector nozzle in the combustion chamber according to the operating condition to thereby optimize combustion in the combustion chamber. A fuel injector system includes a fuel injector configured for injecting fuel into the combustion chamber and an actuator. The fuel injector includes a body and the fuel injector nozzle slideably connected to the body and configured for translating within and injecting a fuel plume into the combustion chamber. The actuator is configured for adjusting the fuel injector nozzle within the combustion chamber. A shape of the fuel plume remains substantially unchanged as the fuel injector nozzle translates within the combustion chamber.

摘要： A four-valve per cylinder engine has two intake valves, two exhaust valves and a centrally located fuel injector. Between each adjacent pair of valves is a valve bridge with a point of minimum separation between adjacent valves. In the present disclosure, the glow plug port is defined in the cylinder top at a location outboard of the minimum separation between adjacent and at a depth which is tangent to an edge of a fuel jet emanating the injector. By placing the glow plug farther outboard than found in the prior art, the glow plug contacts the fuel as it comes out of the injector and as it rebounds off a feature of the piston bowl.

摘要： In a direct fuel-injection engine equipped with a pentroof-shaped piston, cross-sectional shapes containing a piston central axis (Lp) of a cavity recessed in a central part of the piston having a top face with the height varying in the circumferential direction are set so as to be basically identical at each position in the circumferential direction (see broken line). Since the sizes of the cross-sectional shapes of the cavity thereby become different in a region further on the piston central axis (Lp) side than intersection points (e1, d1) in the vicinity of a fuel injection point (Oinj), in order to compensate for this, by correcting in a cross section that is away from the piston pin direction the cross-sectional shape of the broken line into the cross-sectional shape of a solid line so that it enlarges, the size of the cross-sectional shape at each position of the circumferential direction of the cavity is thereby made more uniform, thus making the conditions in which fuel and air are mixed uniform and improving the engine output and reducing harmful exhaust materials.

摘要： A system and method is provided for startup characterization in a turbine engine that provides the ability to accurately characterize engine startup. The startup characterization system and method uses engine temperature sensor data and engine speed sensor data to accurately characterize the startup of the turbine engine by determining when several key engine startup conditions are reached. By storing and analyzing engine sensor data taken during these key conditions of engine startup, the system and method is able to accurately characterize the performance of the engine during startup. This information can be used as part of a trending system to determine when faults in the start transient regime are occurring or likely to occur. Additionally, this information can be used in real time by control systems to better control the startup and operation of the turbine engine.
