Onyx expands propane engine portfolio

Onyx, a supplier of propane engines used in industrial, lawn and garden, and transportation equipment, plans to expand its portfolio of propane engines by adding the following models to its lineup: 302cc horizontal engine, 452cc vertical engine, 459cc horizontal engine, 764/678cc horizontal engine, 999cc horizontal engine and 999cc vertical engine. Onyx propane engines are fully EPA- and CARB-certified with emission certification results below EPA and CARB limits. For example, the 603cc engine is certified at 6.73 g/kWh for carbon monoxide emissions, versus the EPA limit of 610 g/kWh, two orders of magnitude below the EPA limit, and the “black carbon” hydrocarbon plus nitrous oxide (HP + NOx) certified emissions are 56 percent lower than the EPA limit, according to the company.
