Tata Motors introduces India’s first Bio-Methane bus

Home-grown automaker Tata Motors recently showcased the country’s first Bio CNG (compressed natural gas) a.k.a. bio-Methane bus in India.

The company has designed and developed bio-Methane engines for LCV, ICV, and MCV buses and the powertrain options include – 5.7 SGI and 3.8 SGI.

The new bio-methane engines were introduced at the Bio-energy programme, called ‘Urja Utsav,’ and the Tata LPO 1613 bus, which features the top-spec 5.7 SGI NA BS-IV IOBD-II engine that makes 123 bhp and develops 405 Nm of peak torque, was also showcased at the event.

Tata Motors believes that moving towards bio-Methane will not only contribute majorly towards decreasing emissions for a cleaner environment but also help promote the Government of India’s Smart City initiative.

Interestingly, the bio-methane powered Tata LPO 1613 showcased at the event is already in operation by PMPML (Pune Mahanagar Parivahan Mahamandal Limited) in Pune city.

In CNG, the Methane gas co-exists with other heavier hydrocarbons (for which the end application Stoichiometry – air fuel ratio is not adjusted), Bio CNG has only Methane in it and thus it is also called as bio-Methane.

Furthermore, this makes Bio CNG more application friendly and efficient than regular CNG.

For over two decades now, Tata Motors has been working with CNG technology for its vehicles has introduced several technologies in CNG engines related to vehicle performance and safety including sequential gas injection technology, skip fire, plug type coils, long life spark plugs and longer oil drain intervals.
