Omnitek Natural Gas Conversions on Detroit Series 60s Now EPA-Certified

Omnitek Engineering Corp. has received a certificate of conformity from the U.S. Environmental Protection Agency (EPA) for natural gas conversions on Detroit Diesel Series 60 engine families for model years 1988 to 2009.

The certification allows conversions to proceed in 49 states and covers the 11.1-liter, 12.7-liter and 14.0-liter DD60S engine models. Both compressed natural gas (CNG) and liquefied natural gas (LNG) can be used on the converted trucks.

‘The Series 60 remains an extremely popular engine in Class 8 truck applications,’ says Werner Funk, president and CEO of Omnitek Engineering Corp. ‘With more than 1,000,000 engines produced, we are excited to add this engine to our product portfolio.’

The company notes that Series 60 engines converted using Omnitek's proprietary technology can produce 450 hp with low NOx emissions of 0.17 gr/bhp-hr per the EPA SET emissions test (and NOx emissions of 0.04 gr/bhp-hr per the EPA NTE emissions test protocol) without the use of EGR.

According to Omnitek, the company is also finalizing the development of natural gas conversion kits for the Caterpillar C15 and Cummins ISX engine families.
