Canadian Bus Manufacturer Enters Natural Gas Market

| Canada, Vancouver BC

Grande West Vicinity BusCanadian bus manufacturer Grande West Transportation Group Inc. (Grande West) is now offering clean burning, low emission Cummins ISB G engines for delivery on 2017 orders of Vicinity heavy-duty mid-sized transit buses. The ISB G Engine, powered by compressed natural gas (CNG) has the lowest North American Emissions standards and is approved from both the US Environmental Protection Agency (EPA) and Air Resources Board (ARB) in California.

This certification represents major emissions reduction well below current EPA nitrogen oxide (NOx) emissions standards – providing the cleanest engine in the bus industry, the company says in a press release. The engine also greatly reduces particulate matter (PM), providing major greenhouse gas benefits.

Grande West says the CNG-powered Vicinity buses will deliver the performance demanded by our customers as well as offer the best maintenance and serviceability available in the market.

Jean-Marc Landry, Executive VP of Sales and Marketing stated, “We are seeing a growing demand for natural gas powered buses. CNG has helped transit customers meet stringent clean air requirements and is now being requested on many tenders in Canada and the US. The CNG option has been a requirement in many of our  tenders as transit agencies move towards lower operating costs associated with CNG.”

Grande West’s Vicinity bus is available in 30 and 35 foot models.

ISB G Engine

Cummins Westport introduced the dedicated natural gas engine for school bus, shuttle, transit, medium-duty truck, and vocational vehicle markets in 2016. Based on the Cummins ISB6.7 diesel platform, the Cummins Westport ISB6.7 G offers up to 240 hp (179kW) and 560 lb-ft (759 Nm) of torque, and is available with automatic transmissions. The ISB6.7 G meet U.S. Environmental Protection Agency (EPA), California Air Resources Board (ARB) 2016 emissions regulations, ARB’s optional low oxides of nitrogen (NOx) standard of 0.1 g/bhp-hr, and it meets 2017 EPA greenhouse gas (GHG) requirements a year ahead of schedule.

The ISB6.7 G features the same advanced combustion controls with Three-Way Catalyst (TWC) as Cummins Westport’s ISL G & ISX12 G engines. It operates on 100 percent natural gas, which can be carried on the vehicle in either compressed or liquefied form (CNG / LNG respectively). It can also run on 100 percent biomethane or renewable natural gas, which meets published Cummins fuel specifications.
