Patent number: 7971433Abstract: A system and method for treating exhaust gasses from an engine is described. In one example, the exhaust gasses are routed from the engine to atmosphere through a helical exhaust passage. The helical exhaust passage includes a plurality of spatially separated exhaust passages that separates the exhaust flow into separated smaller flows, wherein the smaller flows are re-introduced into a common passage and re-combined to form a single exhaust flow, and wherein the plurality of spatially separated exhaust passages induces a helical flow pattern within the re-combined exhaust flow.Type: GrantFiled: February 14, 2008Date of Patent: July 5, 2011Assignee: Ford Global Technologies, LLCInventors: Daniel Michael Kabat, Furqan Zafar Shaikh, Bryan Christopher Stoll, Sandro Balestrino, Michael Levin

Patent number: 6711491Abstract: A method for calibrating an output signal of a mass airflow (MAF) sensor in operative communication with an induction system of an internal combustion engine is provided. The method comprises the steps of determining an engine speed value, determining a maximum MAF output signal value at the engine speed value, detecting a mean MAF output signal value at the engine speed value, and correlating the MAF output signal with an airflow rate value as a function of the MAF output signal value, mean MAF output signal value and engine speed.

Patent number: 6609499Abstract: A fuel injection system for a gaseous-fueled engine is provided. The fuel injection system comprises at least one gaseous fuel injector for each of the engine cylinders, wherein each fuel injector is located proximate the intake manifold. A guide tube connects each of the gaseous fuel injectors to at least one of the intake ports. The guide tube comprises a fluid passage arranged within the respective intake port substantially tangent and adjacent to an interior wall of the intake port and directed toward the respective intake valve. The guide tube is adapted to deliver high-pressure gaseous fuel from the injector to the respective combustion chamber along the interior wall of the intake port. In this way, the high velocity peripheral fuel charge creates a lower pressure central core within the intake part which, in turn, increases the overall intake charge flow and engine volumetric efficiency.Type: GrantFiled: November 8, 2001Date of Patent: August 26, 2003Assignee: Ford Global Technologies, LLCInventors: Daniel Michael Kabat, Xiaoguo Tang, William Francis Stockhausen
