Emission Management

Fuel metering for exhaust thermal management

Operating with high precision, Thomas fuel metering pump systems provide a number of unique benefits thanks to their versatile use in passenger and commercial vehicles. Whether gasoline and diesel or alternative fuels such as e-fuels or biofuels, Thomas pump systems deliver and control substances with supreme reliability and in line with demand. They combine several functions in a dedicated system and, thanks to the principle of a magnetically driven reciprocating piston established at Thomas, guarantee consistently high levels of metering quality over the entire service life.

In addition to precise metering, the self-priming systems include a shut-off function that prevents unwanted fuel flow, thus making them suitable for use in safety-critical applications.
