Renewegy is currently evaluating the feasibility of a hybrid engine and system redesign for a leading grounds keeping equipment company. In 2015, new emission standards put in place by the Clean Air Act become effective for diesel engines with 75 horsepower and above, known as a tier 4 engine. A fair amount of current engine designs fail to meet the new requirement, forcing a redesign by companies that wish to sell grounds keeping equipment in the United States.

The new emission standards offer a few different options for redesign. First, a company can design an entire system to reduce power losses associated with hydraulics and other systems. Reducing the power requirements would eliminate the need for a tier 4 engine and allow a tier 3 engine that will fit emission standard. Second, a company can outfit a tier 3 engine aided by a hybrid motor to create the level of peak horsepower needed while staying under the emissions limit.  Finally, a company can redesign systems that are powered by hydraulics to systems that are powered by electric motors; this will reduce the power demand s on the engine and allow a tier 3 diesel engine to be used.

Renewegy has experience in emission certifications, engine design, and system controls. The project is a good match for the customer’s needs and Renewegy’s capabilities.
