(Natural Gas for Vehicles) returned to the fore after the rise in gasoline and ethanol prices. In order to increase the sector’s competitiveness, fight fraud and improve publicity about the fuel, the Brazilian Biogas Association (ABiogás) announces the creation of the National CNG Committee
According to ABiogás, the CNG
depends on many small and medium-sized businesses. At the National CNG Committee
, they will be represented by associations, including the Federation of Industries of Rio de Janeiro (Firjan), the Vehicle and Accessories Repair Industry Union (Sindirepa) and the National Organization of the Petroleum Industry (ONIP).
O National CNG Committee
will have the objective of defending agendas that are common to all companies involved in the industry. “On a daily basis, the commercial negotiation belongs to each one. But within the committee, we will assess what is common to all”, says Gabriel Kropsch, vice-president of ABiogás
According to the National CNG Committee
, all the accidents
that occur with gas vehicles are caused by conversions made by illegal companies
. One of the objectives will be to identify offenders to prevent further irregularities.
Despite the fuel economy, gasoline models do not deliver good performance when converted to CNG
. This is due to the low compression ratio, which usually improves on flex or ethanol powered models.
For good combustion of CNG, a compression ratio of at least 13:1 will be required. Gas-only cars have compression ratio
between 8:1 and 10:1, being insufficient for good combustion.
Roughly speaking, flex vehicles
or those powered by alcohol need more energy to change the fuel from a liquid to a gaseous state. Thus, when converted to CNG, the average working temperature is higher. Therefore, flex or ethanol models theoretically work better than gasoline if they are converted to CNG.
According to a study carried out by Comgás, vehicle owners with the installation of CNG
they even save, on average, 50% of the amount that another driver would spend on a flex model, for example. The percentage may vary depending on the region of the country, but it is evident that the installation of a natural gas vehicle kit is an interesting resource for those who want to save money.
The law says that all vehicles with gas kit
installed must undergo an annual inspection, although many owners do not pay the necessary attention to safety. It is necessary to look for a workshop that is both approved by Inmetro and registered by Denatran.
For the inspection, the owner must present the prior authorization from Detran (proving that his vehicle was able to receive the installation), a certificate of quality from the installer and an invoice for installation and components. It is worth remembering that when driving in the car carrying the documentation of the CNG
with expired validity, the owner may have his car’s annual license denied by Detran.
