摘要： A method for improving ignition of a spark ignited internal combustion engine by controlling the composition of recirculated exhaust gas. It is assumed that the engine has a spark ignition system and an exhaust gas recirculation (EGR) loop such that at least one of the combustion cylinders is an EGR cylinder that generates an EGR stream carried by the EGR loop. Thus, the combustion charge is a mixture of air, fuel and recirculated exhaust. A first step is receiving combustibility data representing the current ignitability of the charge. It is then determined whether the energy of the ignition system is sufficient to ignite the charge. If not, the amount of hydrogen in the EGR stream is increased, which increases the ignitability of the charge.

摘要： A method and system for controlling recirculated exhaust gas composition and quantity provided to an internal combustion engine, which has one or more separately controllable combustion cylinders, a main exhaust line and an exhaust gas recirculation (EGR) loop. A first exhaust valve is connected to the main exhaust line, and a second exhaust valve is connected to the EGR loop. The operation of the exhaust valves is controlled such that exhaust does not flow through both exhaust valves at the same time. Control of the exhaust valves is coordinated with the main fueling event used to control the exhaust composition exiting each valve for every cylinder on every cycle. During each engine cycle, a post-combustion fuel injection event is also used to add fuel to the exhaust in-cylinder, which flows only through the second (EGR) exhaust valve.

摘要： A method of preventing a pre-ignition event within a cylinder (20) of a spark ignition engine (100) involves taking in-cylinder measurements and using the measurements to determine the instantaneous heat being released within the cylinder (20) as a function crank angle. If significant heat is being released before the intended spark timing, additional fuel is injected into the cylinder (20) immediately following the detection of early heat release (pre-ignition) within the same engine cycle, preferably within 45 crank angle degrees following the detection of pre-ignition. The additional fuel quenches the heat released within the cylinder (20) to prevent a pre-ignition event.
摘要翻译：一种防止火花点火发动机（100）的气缸（20）内的预先点火事件的方法包括进行气缸内测量并使用测量来确定作为功能曲柄的气缸（20）内释放的瞬时热量角度。如果在预期的火花正时之前释放出明显的热量，则在检测相同发动机循环中的早期放热（预点火）之后，最好在检测之后的45个曲柄角度内，立即将额外的燃料喷入气缸（20）的预燃。额外的燃料淬火在气缸（20）内释放的热量以防止预先点火事件。

摘要： A method using exhaust gas recirculation (EGR) in an internal combustion engine. The engine has at least one “dedicated EGR cylinder”, whose entire exhaust is recirculated back to all the engine cylinders. The dedicated EGR cylinder is operated at a rich air-fuel ratio, and the other cylinders are operated stoichiometrically so that a conventional three way catalyst may be used to treat the exhaust. A fuel injector is used to inject fuel into the combustion chamber of the dedicated EGR cylinder after initiation of the main combustion event. This post injection method overcomes flammability limits of a dedicated EGR cylinder, and increases the hydrogen (H2) and carbon monoxide (CO) in its exhaust.
