摘要： The present invention is an apparatus for controlling a variable geometry turbocharger (VGT) in closed loop and open loop modes, and a switching mechanism for determining whether open loop or closed loop control laws should be used. In the closed loop mode, a correction factor, obtained from a pressure correction map based on engine speed and atmospheric pressure, is subtracted from the desired boost pressure to prevent overspeed of the turbocharger at lower atmospheric pressures. The actual boost pressure is then compared to the desired boost pressure after correction to obtain a boost pressure error signal. The boost pressure error signal is used as an input to a proportional integral differential control law that responsively produces a desired VGT vane position. A minimum limit on the desired VGT vane position is based on engine speed and fuel quantity, whereas a maximum allowable vane position may be a predetermined constant or function. A linearization map is used to obtain a VGT current signal that is transmitted to an actuator for moving the vane position.

摘要： A method of operating a diesel engine which overcomes problems encountered during use of a low cetane fuel with long ignition delays is disclosed. The method provides for a staged injection of an emulsified diesel fuel into the combustion chamber of the diesel engine. In particular, the method includes the steps of (A) injecting a pilot volume of an emulsified diesel fuel into a combustion chamber of the diesel engine, wherein the emulsified diesel fuel includes water and diesel fuel, (B) compressing the pilot volume of the emulsified diesel fuel within the combustion chamber during a compression stroke of the diesel engine, and (C) injecting a main volume of the emulsified diesel fuel into the combustion chamber of the diesel engine, whereby heat generated by compression of the pilot volume of the emulsified diesel fuel causes the pilot volume of the emulsified diesel fuel to combust so as to ignite the main volume of the emulsified diesel fuel.

摘要： Past exhaust emission control systems have failed to cool the exhaust gas prior to mixing with the intake air. The present exhaust gas recirculation system cools a flow of exhaust gas with a common coolant being used to cool an engine prior to mixing the flow of exhaust gas with a flow of intake air. The present exhaust gas recirculation system includes a control system for monitoring an operating parameter of an engine. The control system interprets a signal sensing the operating parameter within a controller and the controller causes an exhaust valve regulator to move between an open position and a closed position. Additionally, a plurality of paths or maps, for example, one being a normal coolant temperature strategy and another being a high coolant temperature strategy is used. In the normal coolant temperature strategy, with the exhaust valve regulator in the open position the supply of fuel to the engine would be advanced. And, in the high coolant temperature strategy, with the exhaust valve regulator in the closed position the supply of fuel to the engine would be retarded. Thus, the emissions emitted from the engine are maintained within a preestablished parameter.
摘要翻译： 过去的废气排放控制系统在与进气混合之前未能使废气冷却。 本废气再循环系统在将废气流与进入空气流混合之前，用用于冷却发动机的共同冷却剂来冷却废气流。 本废气再循环系统包括用于监测发动机的运行参数的控制系统。 控制系统解释感测控制器内的操作参数的信号，并且控制器使排气阀调节器在打开位置和关闭位置之间移动。 此外，使用多个路径或地图，例如一个是正常的冷却剂温度策略，另一个是高冷却剂温度策略。 在正常的冷却剂温度策略中，随着排气阀调节器处于打开位置，发动机的燃料供应将提前。 而且，在高冷却剂温度策略中，随着排气阀调节器处于关闭位置，发动机的燃料供应将被延迟。 因此，从发动机排放的排放物保持在预先建立的参数内。

摘要： A parasitic load control system is provided. The system may include an exhaust producing engine and a fuel pumping mechanism configured to pressurize fuel in a pressure chamber. The system may also include an injection valve configured to cause fuel pressure to build within the pressure chamber when in a first position and allow injection of fuel from the pressure chamber into one or more combustion chambers of the engine when in a second position. The system may further include a controller configured to independently regulate the pressure in the pressure chamber and the injection of fuel into the one or more combustion chambers, to increase a load on the fuel pumping mechanism, increasing parasitic load on the engine, thereby increasing a temperature of the exhaust produced by the engine.

摘要： Certain exhaust after-treatment devices, at least periodically, require the addition of unburnt hydrocarbons in order to create reductant-rich exhaust conditions. The present disclosure adds unburnt hydrocarbons to exhaust from at least one combustion chamber by positioning, at least partially within a combustion chamber, a mixed-mode fuel injector operable to inject fuel into the combustion chamber in a first spray pattern with a small average angle relative to a centerline of the combustion chamber and a second spray pattern with a large average angle relative to the centerline of the combustion chamber. An amount of fuel is injected in the first spray pattern into a non-combustible environment within the at least one combustion chamber during at least one of an expansion stroke and exhaust stroke. The exhaust with the unburnt amount of fuel is moved into an exhaust passage via an exhaust valve.
