    摘要: A control system and method for improving vehicle fuel economy is provided. A base timing module generates a base timing signal. A trim module generates a timing trim signal based on a calibratable compensation factor. A vehicle speed trim module adjusts a calibration parameter (such as engine timing for example) based on the base timing signal and the timing trim signal. According to some implementations, the trim module includes a base trim module and a vehicle speed compensation module and a calibratable compensation factor module. The vehicle speed compensation module generates a vehicle speed compensation factor. The base trim module generates a base trim signal based on the vehicle speed compensation factor or the calibratable compensation factor. The base trim signal can be based on a speed of the engine. The base trim signal can further be based on a quantity of fuel delivered to the engine.

    摘要: A multiple path air mass flow sensor assembly includes an inlet duct which is divided into at least two separate ducts. A first duct has an air mass flow sensor disposed in conventional fashion therein. A second duct includes a damper or valve which may be selectively, partially or fully opened. At low air flow rates, the damper is closed forcing all air through the first duct. As engine speed increases and the air mass flow rate increases, the damper opens, either fully at a predetermined flow rate or proportionally over a predetermined flow rate range, to allow a larger volume of air through the inlet duct. The signal from the air mass flow sensor is adjusted by the engine controller to compensate for the (bypass) air flowing through the second duct.

    摘要: A method for calibrating an engine is provided. The engine includes a cylinder for combustion of a fuel. The method includes setting combustion parameters of the engine, detecting a combustion noise during combustion proximate to the cylinder, detecting an engine sound radiated from the engine during combustion, adjusting the combustion parameters and repeating the steps of detecting a combustion noise and detecting an engine sound. The method further includes generating a relationship between the combustion noises and the engine sounds, determining a combustion noise level that correlates to a predefined engine sound threshold from the relationship, adjusting a speed of the engine and a load on the engine and repeating the previous steps to determine a combustion noise level for each engine speed and engine load setting, and calibrating the engine using the combustion noise levels.
