One of the biggest advantages of FreeTron Bifuel system is the reduction of exhaust emissions. Combustion of gas is much more environmentally friendly than regular diesel Engine. By adding gas the combustion of diesel is increased from an 89% efficiency (hier wird der Wirkungsgrad beschrieben, dass wenn Gemisch gefahren wird, der Wirkungsgrad von Diesel bis auf 97% erhöht wird) up to about 97%. And also the carbon footprint shows significant improvement: LPG operation compared to pure diesel vehicles emits (?) 5 to 18 percent of the greenhouse gas CO2. Particle emissions are reduced by up to 35%.
