Since last years, the whole world is moving towards a new direction. Sustainable energy is one of our priorities; trying to reduce pollutants as maximum as possible and avoiding the petrol dependency are some ways to achieve that. In this direction, engineers are working in electric cars, which have zero consumption. However, batteries still don’t have sufficient autonomy such as an internal combustion car. Furthermore, when you are running out of batteries, the recharge time is too much compared to the 5 minutes that takes to fill a tank. In a few years this could be solved, but before that occurs, some engineers are researching other ways to consume less petrol and pollute less, putting emphasis on energy efficiency and use of renewable energy. This need for increased efficiency has placed the diesel engine in the spotlight due to its superior fuel efficiency compared to spark ignition engines. In this paper I will explain how we have been investigating a new kind of engine that runs with regular gas but using thermal ignition. Using the same principles as Diesel engines, it is possible to run an engine with regular gas but with a really lean mixture, reducing the pollutants and the consumption and gaining efficiency. And finally I will expose the obtained results and the conclusions.
