Omnitek receives EPA approval for Detroit Diesel Series 60 natural gas engine

Omnitek Engineering Corp. said it has received approval from the U.S. Environmental Protection Agency (EPA) for its Detroit Diesel Series 60 engine families for model-years 1988 to 2009.

The Certificate of Conformity allows diesel-to-natural gas engine conversions in 49 states. It covers the 11.1L, 12.7L and 14.0 DD60S engine models.

Omnitek will offer 100% dyno- tested “drop-in” ready converted engines, configured for quick installation. An assembly line engine remanufacturing/conversion process will assure that engines are in “as new” condition with the highest quality and uniformity, Omnitek said.

“There is significant pent up demand for converted Detroit Diesel Series 60 natural gas engines and we expect strong sales momentum in the quarters ahead as fleet customers take advantage of the favorable economics of natural gas and our ‘drop-in’ engine program. The Series 60 remains an extremely popular engine in Class 8 truck applications. With more than 1 million engines produced, we are excited to add this engine to our product portfolio,” said Werner Funk, president and CEO.

Omnitek’s conversion results in an engine producing 450 hp. with low NOx emissions of 0.17 gr/bhp-hr per the EPA SET emissions test and low NOx emissions of 0.04 gr/bhp-hr per the EPA NTE emissions test protocol, without the use of EGR.

“As engines are converted to use 100% natural gas, CNG or LNG, the payback on a diesel-to-natural gas truck conversion can be as short as 16 months, including the cost for the engine, fuel storage system and installation labor. This is a significant improvement compared with diesel-dual fuel technology, which uses a mix of diesel and only a small amount of natural gas,” Funk said.

Omnitek is working to finalize the development of the Caterpillar C15 and Cummins ISX engine conversion kits.
