By using the polytropic exponent (n) as the intermediate medium information, the air-fuel ratio inside the cylinder is measured from the compressed pressure inside the cylinder at the respective points of time.SAITO SHINICHIROOMORI SHOGO
An apparatus, system, and method are disclosed for measuring a normalized air-to-fuel ratio. A normalized air-to-fuel ratio is measured by providing an engine control module, providing a first wide-band oxygen sensor in fluid communication with an exhaust stream, adjusting the oxygen pumping ...
PURPOSE:To measure an air fuel ratio from a light emission intensity with high precision without being affected by a combustion temperature and a combustion pressure by applying time integration to a radical light emission intensity detected in a specified area. CONSTITUTION:A detection area of a ra...
