Title: Innovations by Dennis N Stenz
Introduction
Dennis N Stenz is an accomplished inventor based in Mount Calvary, WI (US). He holds a total of 5 patents that showcase his contributions to the field of emissions control and engine design. His innovative spirit has led to advancements that improve the efficiency and environmental impact of small internal combustion engines.
Latest Patents
One of his latest patents is an emissions control system for small internal combustion engines. This system includes a control valve associated with a fuel line and a vent line that connects the fuel tank to the carburetor. When the engine is not running, the control valve automatically closes both lines, trapping fuel vapors within the fuel tank and vent line. This prevents the supply of liquid fuel to the carburetor. Upon engine startup, the control valve opens the vent line and fuel line, allowing fuel vapors to be consumed by the engine while also supplying liquid fuel. Additionally, this evaporative emissions control system can work with various fuel tank sealing and venting assemblies to prevent fuel vapor escape into the atmosphere.
Another significant patent by Stenz is for an engine and pump assembly that features a combined housing. This design integrates both the engine and pump into a single housing structure. The first housing section defines parts of both the engine and pump housing, with an opening that supports the crankshaft through a bearing. The design includes a pump driving mechanism that connects to the crankshaft, enhancing the efficiency of the engine-pump combination.
