Compared Fuel Consumption and Acceleration of a Dual-Fuel Commercial Vehicle when Propelled by Gasoline or by Compressed Natural Gas (CNG)

The CNG plan has been in practise over five years in Argentina.

There are innumerable opinions from the users as regards the behaviour of the converted vehicles but no data resulting from specific measurements.

Taking this into account, the Thermal Machinery Laboratory (TML) decided to compare the comsumption and acceleration of a conventional vehicle that functions both with gasoline and CNG using simple measurements which will provide immediate results.

Thus, in energetic terms, gasoline consumption related to the unit of distance covered resulted in up to a 36% higher than that of the CNG.

Acceleration capacity was reduced in the CNG adapted vehicle, from 10 to 12% as from still position while when accelerating in fourth gear the decrease was higher.
