Alliance AutoGas Engineered Systems

Our EPA certified autogas systems have been through rigorous Environmental Protection Agency (EPA) testing prior to receiving EPA certifications. These tests include rolling road dynamometer emissions testing and engine dynamometer cell testing. Each year, our engineers build and test bi-fuel systems for new vehicle platforms in order to meet the demands of fleets nationwide. Currently, we lead the industry with 358 EPA Certificates of Conformity and 81 Intermediate Age Vehicle Notifications spanning 1948 vehicles, which can be viewed HERE.
