DEUTZ Field Emission Downgrade (EDG)


DEUTZ engines with emission levels of stage IIIB / IV / TIER 4 interim are designed for the use of high-quality fuels, which are available in countries that are subject to the current exhaust emission legislation. Sale and export of used equipment in so-called secondary markets makes it necessary for the engines to be modified, in order to ensure safe and trouble-free operation. Among other things, combustion and exhaust after-treatment system need to be adapted to the higher sulfur content in diesel fuel in secondary markets.


DEUTZ Service offers cost-effective Emission-Downgrade-Kits that are individually matched to the engine type and system, allowing for market-oriented prices for used machines. DEUTZ also offers new engines that are downgraded to stage IIIA / TIER 3, providing excellent performance without exhaust gas after-treatment.


Downgrade Kits are available within the DEUTZ Service Network - you can find your local DEUTZ Partner here.
