CANADIAN BUS MANUFACTURER ENTERS CNG BUS MARKET

Canadian bus manufacturer Grande West Transportation Group Inc. (Grande West) started 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.

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.
