Welcome to Schneyer Automotive Technologies, LLC

We have over 12 years of experience working on advanced projects using compression ignition engines; including feedgas, aftertreatment, boost system, EGR system, alternative fuels, and fuel system work. In that time, we have worked on site at most of the well known engine development facilities in the world.
