摘要： A hydrogen enhanced gasoline engine system using high compression ratio is optimized to minimize NOx emissions, exhaust aftertreatment catalyst requirements, hydrogen requirements, engine efficiency and cost. In one mode of operation the engine is operated very lean at lower levels of power. A control system is used to increase equivalence ratio at increased torque or power requirements while avoiding the knock that would be produced by high compression ratio operation. Accordingly reduced hydrogen requirements at high power can significantly reduce the cost and size of onboard hydrogen generator technology. Increased in-cylinder turbulence and stratified hydrogen injection can be used to minimize hydrogen requirements for operation at a given equivalence ratio value. In another embodiment, hydrogen enhanced exhaust gas recirculation (EGR) at all power levels is used.

摘要： Fuel management system for enhanced operation of a spark ignition gasoline engine. Injectors inject an anti-knock agent such as ethanol directly into a cylinder. It is preferred that the direct injection occur after the inlet valve is closed. It is also preferred that stoichiometric operation with a three way catalyst be used to minimize emissions. In addition, it is also preferred that the anti-knock agents have a heat of vaporization per unit of combustion energy that is at least three times that of gasoline.

摘要： A hydrogen enhanced gasoline engine system using high compression ratio is optimized to minimize NOx emissions, exhaust aftertreatment catalyst requirements, hydrogen requirements, engine efficiency and cost. In one mode of operation the engine is operated very lean (equivalence ratio O = 0.4 to 0.7) at lower levels of power. Very lean operation reduces NOx to very low levels. A control system is used to increase equivalence ratio at increased torque or power requirements while avoiding the knock that would be produced by high compression ratio operation. The increased equivalence ratio reduces the amount of hydrogen required to extend the lean limit in order to avoid misfire and increases torque and power. Reduced hydrogen requirements at high power can significantly reduce the cost and size of onboard hydrogen generator technology. Increased in-cylinder turbulence and stratified hydrogen injection can be used to minimize hydrogen requirements for operation at a given equivalence ratio value. In another embodiment, vehicle NOx emissions can be suppressed to low levels and knock can be prevented by use of hydrogen enhanced exhaust gas recirculation (EGR) at all power levels with stoichiometric operation and a 3-way exhaust aftertreatment catalyst. Alternatively, EGR can be used with lean operation to keep NOx at low levels while the equivalence ratio is increased to provide higher torque and power capability. The effect of reduced peak power due to charge dilution to avoid knock can be minimized by boosting, using turbocharging or supercharging.
摘要翻译：优化了使用高压缩比的氢气增强型汽油机系统，以最大限度地减少NOx排放，废气后处理催化剂要求，氢气需求，发动机效率和成本。在一种操作模式中，发动机在较低功率水平下运行非常稀薄（当量比O = 0.4至0.7）。非常精益操作将NOx降低到非常低的水平。控制系统用于在增加转矩或功率要求的同时提高当量比，同时避免由高压缩比操作产生的爆震。增加的当量比减少了扩大稀薄极限所需的氢气量，以避免失火并增加扭矩和功率。在大功率下降低氢气需求可显着降低机载氢发生器技术的成本和尺寸。可以使用增加的缸内湍流和分层氢气喷射来最小化在给定的当量比值下操作的氢气需求。在另一个实施方案中，车辆NOx排放可以被抑制到低水平，并且可以通过使用具有化学计量操作的所有功率水平的氢增强废气再循环（EGR）和三向排气后处理催化剂来防止爆震。或者，EGR可以用于稀薄运行，以将NOx保持在低水平，同时增加当量比以提供更高的扭矩和功率能力。通过使用涡轮增压或增压来升压，可以将由于充电稀释而引起的峰值功率降低以避免爆震的效果最小化。

摘要： Fuel management system for efficient operation of a spark ignition gasoline engine. Injectors inject an anti-knock agent such as ethanol directly into a cylinder of the engine. A fuel management microprocessor system controls injection of the anti-knock agent so as to control knock and minimize that amount of the anti-knock agent that is used in a drive cycle. It is preferred that the anti-knock agent is ethanol. The use of ethanol can be further minimized by injection in a non-uniform manner within a cylinder. The ethanol injection suppresses knock so that higher compression ratio and/or engine downsizing from increased turbocharging or supercharging can be used to increase the efficiency of the engine.

摘要： A method for reducing required octane number and spark ignition gasoline engine system with hydrogen-enhanced knock resistance. The method includes the addition of hydrogen or hydrogen-rich gas containing carbon monoxide to gasoline. Octane number can be improved. A spark ignition gasoline engine system is provided to supply gasoline and hydrogen or hydrogen-rich gas to the engine at a varying hydrogen or hydrogen-rich gas to gasoline ratio selected both to prevent knock and to ensure a desired level of combustion stability. The engine system may be normally aspirated or boosted and EGR may be added. The hydrogen-rich gas to gasoline ratio may be controlled as a function of boost pressure, torque, engine speed, or air/fuel mixture ratio.

摘要： Fuel management system for operation of a spark ignition gasoline engine. The system includes a gasoline engine powering the vehicle and a source of gasoline for introduction into the engine. A source of an anti-knock fuel such as ethanol is provided. An injector directly injects the anti-knock fuel into a cylinder of the engine and the control system shuts down the engine by stopping gasoline and anti-knock agent flow into the engine during vehicle deceleration and idling and restarts the engine upon driver demand. Direct ethanol injection and engine shutdown results in efficiencies similar to those of full hybrid vehicles.

摘要： Engine management system for operation of a direct injection spark ignition gasoline engine. The system includes a gasoline engine, a source of gasoline and a source of an anti-knock agent. Gasoline and anti-knock agent are introduced into a proportioning valve that delivers a selected mixture of gasoline/anti-knock agent to a high pressure pump. At least one injector receives the selected mixture from the high pressure pump and delivers the mixture into a cylinder of the engine. The engine management system provides a rapidly variable mixture of directly injected anti-knock agent and gasoline which prevents knock as the engine torque increases.
