Abstract
A system for measuring quality of fuel in an engine is disclosed. The system includes a fuel quality measuring unit and a controller in communication with the fuel quality measuring unit. The fuel quality measuring unit includes a first valve, a second valve, and a quality measurement sensor disposed between the first valve and the second valve. The controller is configured to determine whether the engine is running in a steady state condition, and identify a measurement window based on a pressure of the fuel at an inlet, an Intake Manifold Pressure (IMP), and the steady state condition. The controller is configured to control an opening and a closing of the first valve, the second valve, and a fuel metering valve during the measurement window. The controller is configured to determine the quality of the fuel captured between the first valve and the second valve by the quality measurement sensor.
