NEW HUDSON, MI – Icom North America, a developer and manufacturer of liquid-injection propane-autogas systems for commercial and consumer vehicles, has received 17 new U.S. Environmental Protection Agency (EPA) certifications for its patented JTG II Propane Liquid Injection bi-fuel systems.

The new certifications cover approximately 200 2010-2012 General Motors Chevrolet- and GMC-brand light-duty trucks and SUV platforms with 4.8L and 5.3L engines. The EPA certifications allow Icom to convert these fleet vehicles in the U.S. market for propane-autogas bi-fuel use.

The Chevrolet-brand vehicles include Silverado, Tahoe, Express vans, Avalanche and Suburban. The GMC-brand vehicles include Sierra, Yukon and Savana vans.

Icom's JTG II system is now available for over 400 vehicle platforms, the most of any liquid-injection system in the U.S. market. Icom's total number of EPA certifications now stands at 40.

Icom's EPA certifications now cover approximately 3 million vehicles, primarily Ford and GM fleet vehicles. The company soon expects to receive additional certifications for Ford, GM, and Dodge vehicles.

Jasper Engines and Transmissions Alternative Fuels Division provided Icom with the GM vehicles for integration, according to Icom. Jasper, founded in 1942, is an Indiana-based, employee-owned company that is one of the nation's largest remanufacturers of a diverse line of drive-train components.

The Jasper Alternate Fuels Division was formed 20 years ago and has over 70 installation locations throughout the U.S. Icom previously had been awarded 23 EPA certifications: two for Ford 6.8-liter E-Series vehicles, 13 for 2009- through 2011-model-year Ford light-duty trucks equipped with 5.4- and 4.6-liter engines covering E-Series vans, Navigators and Expeditions, and eight for all Ford E-Series vans, Expeditions, Crown Victorias, Lincoln Town Cars and Navigators.

Since 2004, Icom North America has been supplying its patented JTG liquid-injection propane systems to bus, truck, and commercial vehicle manufacturers in the United States. Approximately 150,000 vehicles worldwide have been equipped with the Icom JTG Propane System since 2004. JTG II includes an enhanced multi-valve for rapid filling and an integrated fuel pump for ease of service.

Currently, propane fuel is used primarily on commercial vehicles. Icom's proprietary vehicle-conversion systems also can be used on any gasoline fuel-injected car or truck, including shuttles, vans, hybrids, taxis, police vehicles or passenger cars.

The company's patented JTG liquid-propane injection application is a fully-integrated, mono-fuel or bi-fuel engine system. It is designed specifically for use with OEM gasoline engines. The JTG II system often delivers substantial fuel economy improvements when compared to propane-vapor-injection systems, as well as increased power, torque and performance.
