摘要： A system is described using a fuel quality sensor for controlling various aspects of engine operation. In particular, an acoustic wave sensor is utilized to measure viscosity and density of gasoline fuels. This measurement is utilized to predict engine combustion quality during an engine start. Based on the prediction, the method adjusts engine operating parameters (such as fuel injection amount and ignition timing) to achieve improved vehicle driveability and engine combustion.

摘要： As one example, a method is provided for controlling a relative amount of air and fuel that is provided to a combustion chamber of an internal combustion engine. The method comprises adjusting a relative amount of air and fuel provided to the combustion chamber during an engine start based on a volatility of the fuel identified during a previous engine start. As another example, a vehicle engine system is provided, comprising: an internal combustion engine including at least one combustion chamber; a fuel injector configured to provide fuel to the combustion chamber; a fuel system operatively coupled with the fuel injector including a fuel storage tank; a control system configured to vary an amount of fuel injected into the combustion chamber during an engine start based on a speed response of the engine during a previous engine run-up from rest and a change in an amount of fuel stored in the fuel storage tank before the engine start.

摘要： A system and method for operating an engine having ionization signal sensing include detecting plug fouling and controlling the engine using progressively more aggressive control strategies if the fouling condition persists. A first control strategy may be used when the number of engine starts or running time are below corresponding thresholds and a second strategy otherwise. The first strategy may employ progressively more aggressive control procedures to eliminate spark plug deposits that may include repetitive sparking, exhaust cycle sparking, increasing engine loading, advancing spark timing, increasing air/fuel ratio, and increasing idle speed, for example. The second strategy may include similar corrective actions employed in a different order and/or to a lesser degree in an attempt to eliminate plug fouling without any noticeable change in engine operation or performance as perceived by the vehicle operator. The control strategies may be applied to individual cylinders, cylinder banks, or all cylinders.

摘要翻译： 用于操作具有电离信号感测的发动机的系统和方法包括如果污垢状况仍然存在，则检测堵塞污垢并且使用逐渐更积极的控制策略控制发动机。 当发动机启动次数或运行时间低于相应阈值时，可以使用第一控制策略，否则第二策略。 第一种策略可采用逐步更积极的控制程序来消除火花塞沉积物，例如可能包括重复火花，排气循环火花，增加发动机负荷，提前火花正时，增加空气/燃料比，以及提高空转速度。 第二种策略可以包括以不同的顺序采用的类似的纠正措施和/或在较小程度上试图消除堵塞堵塞，而不会由车辆操作者感觉到发动机操作或性能的任何明显改变。 控制策略可以应用于单个气缸，气缸组或全部气缸。
