Title: The Innovative Contributions of Gordon W. Sweetnam
Introduction
Gordon W. Sweetnam is a notable inventor based in Milford, MI (US). He has made significant contributions to the field of internal combustion engines, holding a total of 4 patents. His work reflects a commitment to advancing automotive technology and improving engine efficiency.
Latest Patents
One of Sweetnam's latest patents is for an internal combustion engine with stratified charge and tumble motion. This innovative design features a tumble control valve located in the intake port upstream of the fuel injector, which creates a high-velocity airflow. The fuel injected by the fuel injector is entrained into this airflow, establishing regions of fuel-rich and fuel-lean mixtures within the cylinder. The airflow circulates about an axis that is substantially perpendicular to the piston’s operation axis.
Another significant patent is for a finger follower rocker arm with an engine valve deactivator. This design includes an outer body that engages the stem of an engine valve, with an inner arm pivotally mounted within the body. The inner arm is moved by the cam lobe of an engine camshaft. A latching pin typically causes the inner arm and outer body to function as a single unit to activate the engine valve. However, selective withdrawal of the latching pin allows the cam lobe to move the inner arm freely, disabling the engine valve without affecting the outer body or valve stem.
