July 8, 2019. Two compressed natural gas (CNG) buses will begin circulating in the Autonomous City of Buenos Aires in the coming weeks. It will be a pilot test driven by the Government with the aim of finding a mobility solution less harmful to the environment and reduce operating costs for transport companies.

One of the vehicles was manufactured by Scania for line 132 and the other by Agrale for line 50. The first is Brazilian industry, with certain Argentine components in the transmission; the second occurred in national territory.

“We can say that the operating cost of buses to CNG, compared to diesel, is 37% lower,” said Bus Manager of Scania Argentina, Jorge Vittar. The Swedish firm has experience in the field: already delivered about 6.000 CNG units for the BRT system in Bogotá, Colombia, called Transmilenio.

Exterior and interior, they are practically identical to the rest of the units of both lines. They measure about twelve meters and have twenty-eight seats.

The badge of these copies is in the driving block. The CNG vehicle of line 132 is equipped with a 280-hp 9.0-liter engine with a range of 290 kilometers and considerably lower noise levels, says Scania.

The CNG bus of line 50 comes with a 7.8-liter engine of 272 HP. According to the density of the traffic, Agrale affirms that it gives autonomy of between 300 and 400 km. Sometimes it can be up to 40 percent of the braking time.

For loading CNG, refueling points will be used in the headings of both bus lines. Each unit has four cylinders in the roof, which will be completed in twenty-five minutes. This operation is shortened by 50 percent if a special peak called NGV1 is used.
