In a bid to decrease carbon fuel consumption in the United States, the EPA intends to mandate the blending of 18.8 billion gallons of biofuels into U.S. gasoline and diesel supplies next year. This translates into a spike of about 300 million more gallons of the biofuel additive ethanol when compared to the current 2016 volume. Unfortunately, if there’s one thing that’s harmful to today’s small engines like the ones found in handheld outdoor power equipment, it’s ethanol.
Ethanol accelerates the deterioration of traditional rubber-based diaphragm materials found in outdoor power equipment engines. This deterioration negatively affects the starting and running performance of gasoline powered products, decreasing their useful life. The issue is so important to the industry that the Outdoor Power Equipment Institute (OPEI) has launched a campaign alerting consumers to the adverse effects of higher ethanol content blended in modern fuels. The fact is, many small engines aren’t even designed to handle current levels of added ethanol, much less increased future levels coming soon.
So what’s the best solution for dealing with these new fuel blends? We think it’s a revolutionary ethanol-proof carburetor from the forward-thinking engineers at Walbro.
With 65 years of experience, Walbro has positioned itself as a global market leader in small engine management and control systems. Our comprehensive gallery of superior products includes ignition systems, fuel injection systems, air/fuel management systems, pumps, valves and fuel storage and delivery systems. With manufacturing and engineering facilities in China, Japan, Mexico, Thailand and the United States, we at Walbro have reach around the world. And for more than five years, our engineers have developed and tested an amazing innovation designed specifically to address the rising ethanol content found in fuel supplies – the Spiral Metering diaphragm carburetor.
What sets the Spiral Metering diaphragm carburetor apart from traditional diaphragm systems is a radical ethanol-proof membrane that renders the system resistant to the additive. This advanced technology, along with a stainless spiral support, ensures superior engine performance. It also means consistent fuel delivery and exhaust emission throughout the life of small engine products.
While the performance of inferior carburetors is impacted by climate and moisture, the Spiral Metering diaphragm is reliable even in extreme temperatures, and provides exceptional performance whether wet or dry. Rigorous testing of the Spiral Diaphragm demonstrated greatly reduced variations in fuel metering performance, an important factor in advanced emission control carburetors and newer electronic carburetor applications.
Modern fuel blends like E15 (15% ethanol, 85% gasoline) often prove harmful to small engine carburetors that can’t handle the aggressive chemicals and increased moisture that comes with the addition of ethanol. But the ethanol-resistant Spiral Metering diaphragm carburetor from Walbro succeeds where conventional products fail, delivering reliable starts and consistent performance every time.
