Center for Alternative Fuels Engines and Emissions


With over 20 years of testing experience, CAFEE engineers have quantified emissions from the full range of engines: from small half-horsepower equipment to high-horsepower locomotive engines and all points in between. Our past programs have covered a broad spectrum of emissions testing: heavy-duty on-highway, non-road applications, spark-ignited engines, locomotive, marine, and alternatively fueled engines. Capable of testing in conformance with applicable EPA, CARB, EURO and other requirements, we pride ourselves on delivering accurate emissions results from nearly any combustion source.

We maintain a full-time staff of engineers and technicians dedicated to testing, so we can provide the best service along timelines that work for you. Among the many services we offer to our clients are:
