Zemission + Exhaust After-treatment

Regulations for exhaust after-treatment is continuously intensified which requires ever more development from the manufacturers. Passenger cars are increasingly being electrified partly or fully. When it comes to long haul heavy vehicles, electrification is currently not an option. Zemission runs a development project where our catalytic combustion technology will revitalize the after-treatment system for diesel engines. 

Within a foreseeable future, heavy vehicles will be electrified. In route-bound and local traffic, this is likely to be successful. Phasing out the diesel engine for long haul traffic is a different challenge. These deliveries have multi-day travel spans, maximum driving range and a minimum of stops are therefore crucial. Interruptions are costly and alternative technology is measured in profitability.

Temperature dependent systems

Today’s exhaust after-treatment for diesel engines require a minimum temperature to function correctly. In stop-and-go traffic or when idling, the rest heat from the engine is not enough for the after-treatment system to function properly. This results in untreated exhausts, that will not be allowed in upcoming regulations.

Zemission develops a new solution

The automotive industry is searching for a solution, and time is short. Zemission is running a development project with an OEM. The goal is to ensure a continuous minimum temperature for the after-treatment system regardless of engine running conditions. With this solution, the diesel engine can continue to be used in situations where there are no other alternatives. The development is progressing and has generated considerable interest.
