As the winner of the prestigious GM Alt Fuels Van Program in 2010, we continue to offer excellent product design, conversion, warranty & tech support and customer service today. We have also invested in our own low pressure system design and will be manufacturer of record for all of our certificated kits, starting in 2018.

We match all OEM warranties and can sell kits to certified installers or handle complete conversions with our one-stop-shop model and many ship-through codes.

Compressed Natural Gas

Natural gas is an odorless, nontoxic, gaseous mixture of hydrocarbons—predominantly methane (CH4). It accounts for about a quarter of the energy used in the United States.

In recent years, 80% to 90% of the natural gas used in the United States was domestically produced. Most natural gas is drawn from wells or extracted in conjunction with crude oil production.

Two forms of natural gas are used in vehicles: CNG and LNG. Both are clean burning, domestically produced, relatively low priced, and widely available. Because of the gaseous nature of this fuel, when stored onboard a vehicle, it must be in either a compressed gaseous (CNG) or liquefied (LNG) state.

Propane Autogas

Also known as liquefied petroleum gas (LPG) or autogas, propane is a clean-burning, high-energy alternative fuel that’s been used for decades to power light, medium and heavy-duty propane vehicles.

Propane has a high octane rating and excellent properties for spark-ignited internal combustion engines. It is non-toxic and presents no threat to soil, surface water, or groundwater.

Propane is produced as a by-product of natural gas processing and crude oil refining. It accounts for about 2% of the energy used in the United States.

Electric

Hybrid Electric Drive Systems drive just like the others in a fleet – no driver training required. Because the system installs under the vehicle body, there’s no impact on cargo space. Hybrid Electric Drive System systems generates 100% of its own electricity during deceleration, eliminating the need for costly fueling infrastructure.

Using electricity to power vehicles can have significant energy security and emissions benefits.

Hydraulic

Hydraulic Hybrid Regenerative Braking Drive Systems can be added to the driveline of a vehicle to regenerate braking energy. Hydraulic pumps and a lightweight accumulator store braking energy and upon acceleration use the stored energy to provide torque to power the wheels. The fuel efficiency gains are achieved by regenerating the braking energy that is normally wasted to heat, and using this energy instead of the internal combustion engine for acceleration.

New and Developing Technology

Eco Vehicle Systems is aggressively looking into new EPA and CARB certified technologies that have the potential to make transit systems safer, greener and more efficient.
