LYON TOWNSHIP, 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, which bring the company’s total number of EPA certifications to 40, cover approximately 200 2010-2012 General Motors Chevrolet and GMC 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 EPA certifications now cover approximately three 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. 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.

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.
