Demonstrator: Engine development

Motivation: Reduction of CO2 emissions by increased engine compression ratio (CR), High water to fuel ratios for Direct Water Injection (DWI) to avoid engine knock limitation for increased engine efficiency, Water recovery from exhaust gas condensation as enabler for self-sustaining water injection and increase of customer acceptance for water injection systems and Stoichiometric air/fuel ratio in entire engine map for low CO2 emissions and RDE compliance.

UFI FILTERS designed the complete treatment system for the purification of the water harvested from the exhaust gases of a gasoline engine, taking care of solid particles and chemicals that can damage the injection line. Read more.

For the Mercedes Demonstrator vehicle with Stoichiometric small TC-VVA-DI water injection engine, the following achievements have been reached: Read more.

Aftertreatment system must provide excellent emissions control under lean (λ>1) conditions, whilst being thermally durable to withstand high temperatures under peak-load λ=1 conditions. Final system design comprised. Read more.

For the JaguarLandRover Demonstrator vehicle with Dry dilute combustion engine, the following achievements have been made: Read more

Lean Combustion Requires higher air delivery to the cylinders, efficient turbocharging at low exhaust gas enthalpy conditions and swift transient response to air mass flow demand (lean switch). Read more

The overall aim is to demonstrate a new generation of gasoline DI engines achieving a ≥ 15% reduction in CO₂ based on a Dry Dilute lean burn combustion concept (JaguarLandRover).
