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.

摘要翻译： 使用燃料质量传感器描述用于控制发动机操作的各个方面的系统。 特别地，使用声波传感器来测量汽油燃料的粘度和密度。 该测量用于在发动机起动期间预测发动机燃烧质量。 基于该预测，该方法调整发动机工作参数（例如燃料喷射量和点火正时），以实现改进的车辆驾驶性能和发动机燃烧。
