LNG/CNG Technology
Our NZE Natural Gas engines use renewable fuels and have the power to get the job done. They are the next step to 100% zero-emissions.
We rigorously test every near-zero-emission class 8 tractor available to ensure it meets our rigorous operational needs - right down to the last mile and the last turn-around minute. Natural Gas and Natural Gas Hybrid Near-Zero-Emission (NZE) trucks meet these and take us a giant leap toward our commitment to a 100% NZE & ZE Fleet.

The First 48
On May 22, 2008, TTSI took delivery of the first 8 Clean LNG Trucks. By July 2011, TTSI had purchased 49 LNG Trucks.
State-of-the-Art Natural Gas Engine Fleet
Cummins Westport
Cummins Westport ISL G Near Zero (NZ) emission engine has 90% fewer NOx emissions than the current North American EPA standard. These trucks use renewal natural gas (RNG) - from organic waste and refined to met emissions standards, and have a 250 mile range. They are an excellent solution for drayage and regional hauls, and we've added them to our green fleet. TTSI is also testing Westport's CNG and Battery Electric Hybrid Engines.

US Hybrid
Kenworth
Kenworth's T680 Prototype is a hybrid propulsion system using battery-electric and near-zero-emission CNG (Compressed Natural Gas). These range-extended electric trucks can operate in zero-emissions mode on batteries for 30 miles. The batteries recharge while driving using the onboard generator powered by the near-zero-emissions natural gas engine.
Kenworth
Kenworth T680 Prototype is a Hybrid Emission Cargo Transport (HECT). Funded in part by the Office of Energy Efficiency and Renewable Energy (EERE), the U.S. Department of Energy and the South Coast Air Quality Management District.
Our trucks are state-of-the-art, featuring Westport Innovation's High-Pressure Direct Injection (HDPI) technology.
