Continental Backs 94UL, Unveils Diesel Project

May13, 2010 — Teledyne-Continental Motors announced this week that it is backing 94UL as the replacement for 100LL avgas. The company has been researching how the lower octane fuel will affect its range of engine models and initial research shows that all of its engines already certified to run on 80/87 octane will still provide rated power with 94UL. TCM’s Bill Brogtdon told AvWeb that 94UL is the same as 100LL but without the tetraehtyl lead that acts as an  octane enhancer.

TCM’s Bill Brogtdon told AvWeb that 94UL is the same as 100LL but without the tetraehtyl lead that acts as an  octane enhancer. Continental claims its turbocharged, low-compression engines will also experience no drop-off in performance. Some high-compression models, however, have shown to have issues with the lower octane fuel and the company is experimenting with several solutions including variable timing, knock detection, and increasing the displacement.

“We’re hopeful that there might be a higher octane unleaded avgas solution in our future that will satisfy a greater proportion of the existing GA fleet and are working with the petroleum industry, aviation manufacturers and others toward that end,” said EAA Vice President of Government Relations Doug Macnair. “It’s very prudent that Continental is focusing their business model on the worst-case scenario so that they will be prepared for the long term regardless of the outcome.”

Continental Announces Diesel Project
With two piston diesel models already on the market, Continental has purchased certified diesel technology from a European company in order to speed the development of its own four- and six-cylinder diesel engine models. TCM’s Johnny Doo told AvWeb that the agreement allows Continental to avoid having to start from scratch and develop the engines as they see fit. Doo says that the four-cylinder model is due out in 2011 with the six-cylinder to possibly follow by 2013.
