For a bright future
The environmental impact of a truck is mainly generated from exhaust emissions. That is why we go all the way when it comes to research and development in cutting emissions and be at the forefront of environmental technology.
Efficient exhaust after-treatment
Diesel engines are highly energy efficient. During combustion the temperature level is high and there is a surplus of air, to make sure that the combustion is almost complete. The hydrocarbon and carbon monoxide levels are low compared with petrol ("otto") engines.
On the other hand diesel engines produce more nitrogen oxides and particles than otto engines. By monitoring combustion, the balance between hydrocarbons/carbon monoxide and nitrogen oxides are regulated.
Diesel fuel has a higher energy value than petrol, but it also contains higher levels of sulphur and aromatic hydrocarbons. Currently, low-sulphur fuel can be found in e.g. Sweden, Finland and the United Kingdom.
