AutoGas

The most sustainable AutoGas

At Repsol, we are committed to advanced solutions for transportation, sustainable development, and technology of the future. AutoGas is the most widely used alternative fuel worldwide as it leads to fuel savings of up to 40%. It also reduces CO2 emission to the atmosphere by around 15%.

How AutoGas works

AutoGas vehicles are dual-fuel vehicles; they are fitted with two tanks, one for gas and another for AutoGas, therefore doubling the vehicles’ range. Their fittings and performance are similar to vehicles using traditional fuels, and the appearance of the vehicle and its trunk is exactly the same as its gas or diesel counterparts.

In Spain, there are now many manufacturers that sell AutoGas vehicles, but, in addition, many gasoline-powered vehicles can be converted to AutoGas. The technology consists in adding a kit comprising a tank, gas lines, a vaporizer, and injectors to a gasoline engine. It does not take up space in the trunk because it is normally placed in the space for the spare tire. Thus, the vehicle becomes a dual-fuel vehicle and can operate interchangeably with AutoGas or with gasoline.

At Repsol, we have been able to take another step in the use of LPG by optimizing its consumption and specifications.

Company scientists and researchers have consolidated their knowledge and technology with AVL and Delphi, leading European engineering companies, to develop a prototype AutoGas vehicle. In addition, For the first time direct injection is possible in the liquid phase of a light fuel, LPG.

This alternative energy source does not produce particulates when burned, complies with the limits on emissions for 2020, and, above all, reduces emissions of CO2 to the atmosphere by around 15% more than gasoline vehicles. 

To develop AutoGas Liquid Direct Injection, the scientists and researchers at the Repsol Technology Center based their work on two essential foundations, the first being that LPG can take on the same properties and functions as conventional gasoline when it is at ambient temperature and is pressurized to a level 10 times greater than atmospheric pressure. The second is that injection with LPG is very similar to injection with traditional fuels.
