Off-Road: Material Handling

There are more than 90,000 off-road large spark ignition engines in California. Many of these engines have no emission controls and some remain in operator fleets for decades. Just one uncontrolled engine can emit as much hydrocarbon and oxides of nitrogen in three eight-hour shifts as a new car certified to California’s cleanest emission standard does over its entire lifetime.

Large spark-ignition engines are a significant source of air pollution. These engines are powered by gasoline, liquid propane gas, or compressed natural gas and are used in commercial and industrial applications, including forklifts, electric generators, airport baggage transport vehicles and a variety of farm and construction applications. They currently account for about 9 percent of hydrocarbon (HC) emissions, 4 percent of carbon monoxide (CO) emissions, 3 percent of oxides of nitrogen (NOx) emissions, and 2 percent of particulate matter (PM) emissions from mobile sources. If left uncontrolled, by 2020 these engines will contribute 24 percent of national HC emissions, 6 percent of CO emissions, 9 percent of NOx emissions, and 5 percent of PM emissions from mobile sources.

HC and NOx emissions form smog and contain toxic compounds such as benzene, so reducing them will benefit our health and environment, especially in terms of respiratory impairment and related illnesses. Some of these engines also emit high levels of CO, which is especially problematic for people who work with or are otherwise active near these engines. Many engines operate in warehouses, ice skating rinks, or other enclosed areas, where personnel who work with or near the equipment can experience increased exposure.

We have provided 3-way catalyst technology in both integrated muffler form and catalytic converter style to original equipment manufacturers (OEMs) and manufacturers of record (MORs) since the inception of the Large Spark Ignited Regulation by the Environmental Protection Agency (EPA) and California Air Resources Board (CARB). These turnkey solutions offer reduced platinum group metals (PGMs), thus stabilizing costs.

Our 2-Way Purimuffler® emissions control systems can easily be installed in material handling equipment. 2-Way Purimuffler® integrates a catalytic converter, muffler and venturi to effectively reduce CO, and odor causing HC from liquefied petroleum gas, compressed natural gas or gasoline powered industrial equipment.
