Patent number: 12234759Abstract: A heat management system for air-cooled engines suitable to power yard care equipment or vehicles. The system may generally comprise an engine, a blower configured to blow ambient cooling air across the engine, and an exhaust system comprising an exhaust header and a muffler. The exhaust header has an inlet end which receives heated exhaust gas from the engine and an outlet end fluidly coupled to the muffler. An air control baffle is configured to redirect a portion of the cooling air from the blower towards the exhaust header and the muffler to enhance cooling the exhaust system. The system may further include an outermost protective shield exposed to equipment operators and an inner heat barrier or shield located between the muffler and protective shield. The system is designed to ameliorate both radiative and convective sources of heat transfer to maintain the protective shield at temperatures below established industry standards.Type: GrantFiled: February 14, 2024Date of Patent: February 25, 2025Assignee: Discovery Energy, LLCInventors: Robert A. Griswold, David Hasler, Brittany Nicole Tremblay, Sean Leroy Winter, Christopher Wolf, Alexander Anthony Yosick

Publication number: 20240308897Abstract: System and method for micro-Super Critical Water Oxidation solids treatment of fecal waste are described. The system includes an injector vessel (112) and a reactor (114). The reactor can receive an injection of a slurry batch and an input of compressed air that is heated over time to a temperature at or above the critical point of water into the super critical fluid phase. A combined concentrator and phase separator (150)) can receive a treated output from the reactor and separate solid ash from liquid and gaseous effluent. A drying tunnel (170) can receive and dry the solid ash. The treatment process includes heating the slurry batch, within the reactor, to a temperature of at or above the critical point of water into the super critical fluid phase and maintaining the slurry batch a minimum temperature, within the reactor, for a predetermined treatment time to produce a treated output.Type: ApplicationFiled: July 15, 2022Publication date: September 19, 2024Inventors: Shannon YEE, David HASLER, Roland LEHMANN, Christian SEILER, Christian FORRER, Christoph FARRÉR, Andreas STAUB, Marco CADUFF, Janine GLATTHARD, Adrian GEMPRELI, Florian FISCHER, Daniel RÜDISÜLI, Valdinei FRASSON, Josef FISCHER, Tobias BLEIKER

Patent number: 11624333Abstract: Engine systems which are safer and have reduced risk of fire are desirable in a wide range of equipment markets. The present engine systems utilize sensors and control systems which reduce the probability of fire or spark exiting the exhaust system. The sensors may monitor a wide range of conditions within the exhaust system to alter the operating parameters of the engine to prevent ignition of objects adjacent the engine system during use. By altering operation of the engine, conditions such as exhaust temperature or unburned fuel can be controlled to minimize risk of undesired ignition.Type: GrantFiled: April 14, 2022Date of Patent: April 11, 2023Inventors: Martin Louis Radue, Marshall Hau, David Hasler, Donald Castle, Michael E.
