Sulfur dioxide (SO2) emissions from diesel combustion remain a major unresolved problem at vehicle scale. Industrial flue gas desulfurization (FGD) systems exist but are too large and heavy for vehicle mounting. No vehicle-scale equivalent of AdBlue exists for SOx control. This paper proposes a compact rotating wet scrubber system inspired by semi-automatic washing machine drum mechanics, using slaked lime (Ca(OH)2) solution as the reactive medium. The system uses a partial exhaust tap, a belt-driven rotating reaction cylinder with internal scooping grooves, and a static central spray pipe to achieve SO2 capture via calcium sulfite precipitation. Three deployment variants are described: vehicle-mounted for trucks, stationary for diesel gensets, and marine hybrid for IMO 2020 SOx compliance. The system is low-cost, retrofit-compatible, and fail-safe. This paper is released as a defensive publication into the public domain to prevent monopolization of this concept and to accelerate open development for the benefit of high-sulfur diesel markets globally.
