LNG/CNG Technology

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. LNG 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.

Operating Goals

  • Servicing the Los Angeles and Long Beach Ports 6 days a week
  • Class 8 Zero Emission Trucks
  • Power to transport 36 to 39K loads
  • Able to travel 6% Grade at minimal 30 to 35 MPH
  • Minimal fueling time & available locations

LNG/CNG Benefits

  • Fuel cheaper than diesel (Domestic/Renewable)
  • Cheaper operating cost/mile than diesel
  • Low NOx Emissions
  • Driver Acceptance

State-of-the-Art Natural Gas Engines

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.
