Emissions from trucks

Emissions from trucks

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 in staying at the forefront of environmental technology.

Efficient exhaust after-treatment
Diesel engines are highly energy-efficient. During the combustion process the temperature level is high and the cylinders are fed with a surplus of air to make sure that combustion is as complete as possible. 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 do. By monitoring combustion, the balance between hydrocarbons/carbon monoxide and nitrogen oxides is regulated.

Fuel quality
Diesel fuel has a higher energy value than petrol does, but it also contains higher levels of sulphur and aromatic hydrocarbons. Currently, low-sulphur fuel can be found in countries such as Sweden, Finland and the United Kingdom.

Cleaning Techniques
There are several ways of reducing emissions. Filters or particle traps reduce the quantity of particles discharged, whereas the catalytic converter efficiently burns exhaust gases under controlled conditions.
 
The Diesel Particle Filter kit can be retrofitted on trucks with Euro 2 and Euro 3 engines, allowing them to operate within eco-classified "green" zones.
 
This kit effectively reduces substances that affect health - carbon monoxide, hydrocarbons and soot particles in the exhaust gases. The closed-loop filter reduces health-impairing emissions by 80-95%, while keeping engine power intact.

There are also new engine technologies that meet the toughest legislation. Exhaust Gas Recirculation (EGR) is today used in parallel with Selective Catalytic Reduction (SCR) on some markets.
