Spark-Ignition Natural Gas Variant Added to Growing Line-Up
Omnitek Engineering spread the word at the North American NGV Conference & Expo in Atlanta that it has completed a pilot project involving 21 refuse collection trucks with the Mack E7 engine, which it plans to add, when approved, to its growing line-up of spark-ignition dedicated-natural gas engines. The 12-liter engine is up for U.S. EPA approval of 1998 through 2006 variants, expected in the first quarter of 2014. The trials in California were conducted under a California Air Resources Board waiver.
Also under development are spark-ignition Omnitek versions of the 1998 through 2006 Detroit Diesel Series 60 and Caterpillar C15 engines.
Omnitek said last month that the S60 and Cat C15 have been chosen for a Seattle-area Puget Sound re-power program disclosed last summer (F&F, July 17).
Omnitek is looking ahead to develop Navistar VT365 and T444E engines, and the Mercedes-Benz 904/906 series engines, for export.
DT466 and DT530 with Minnesota’s Reviva
Already approved are the Navistar DT466 and DT530 engines, for which Omnitek has a new drop-in replacement program with the Minneapolis-based diesel engine remanufacturer Reviva.
Omnitek’s strategy, says vocational sales and product integration VP Jim Cole, is to help operators green their fleets by modifying the installed diesel base as an alternative to new truck (and engine) purchases.
The Omnitek way can be 60% less expensive, Cole says, with fuel-savings payback in as little as 18 months.
“The accumulative fuel savings thereafter can be absolutely huge,” he says. Cole is a veteran of Emissions Solutions Inc., which also offered a spark-ignition version of the DT466.
“Our technology is feasible and affordable, with a projected return on investment of less than two years – a particularly appealing value proposition for large fleet operators given that the service life of some diesel engines can be up to 20 years,” Omnitek CEO Werner Funk said in the company’s Puget Sound announcement.
Omnitek offers three-year engine and five-year emission warranties.
