Revolutionary Engine Tech: Propane Autogas Meets Sustainability Goals

In an exciting partnership, Stanadyne, Katech, and the Propane Education & Research Council (PERC) are ushering in a new era of eco-friendly technology. Their collaboration combines Stanadyne’s direct injection fuel pump and injector system with Katech’s cutting-edge vapor lock technology. The result? A medium-duty engine system that seamlessly delivers propane autogas at a constant 350-bar pressure directly into the engine.

This innovative technology is a game-changer for fleet owners striving to meet the stringent ultra-low emissions regulations scheduled for 2027. Compared to diesel, propane autogas slashes nitrogen oxide emissions by an impressive 96% and curbs carbon dioxide emissions by 5 to 10%, all while maintaining excellent engine performance. Moreover, this engine tech can run on renewable propane, boasting a carbon intensity four times lower than conventional diesel.

One of the most significant hurdles in working with liquified gases like propane is vapor lock, which can disrupt fuel pump operation. However, this joint system has conquered that challenge. During a grueling 250-hour performance and durability test, it successfully powered a standard 6.6L GDI engine. These tests validate this technology’s compatibility with existing engines and highlight propane autogas as a low-carbon alternative to gasoline and diesel engines.
