Our Capabilities

Heavy Duty Engine

While E2A’s heavy-duty cell has historically conducted testing involving on-road, diesel engines with a power range of 150 horsepower to 700 horsepower, the laboratory is capable of measuring raw and dilute emissions for a wide range of engines and fuels.  Prior projects have involved engines with a large array of horsepower, operating on fuels from standard commercially available gasoline and diesel to natural gas, propane, methanol, di-methyl ether, and a multitude of alternative fuels. 

The main thrust of this laboratory is to perform emissions research for heavy-duty engines fueled by diesel or natural gas.

The E2A Team

E2A’s diverse team has over 100 years of experience in the areas of engine and vehicle performance and emission control and are continually recognized as subject area experts by public and private sector stakeholders.
