- Summary:
- Recently, using hydrogen or hydrogen-rich gas as a supplementfuel for spark ignition and compression ignition engines is one ofthe potential solutions for improving brake thermal efficiency,reducing fuel consumption and pollution emissions from internalcombustion engines. This article investigates the effect of HHO gasaddition on engine performance and emission characteristics.HHO gas was produced by the electrolysis process of distilledwater and stored in a high pressure tank before injected into theintake manifold. The experimental study was carried out on a 97 ccSI engine equipped with two injection systems (HHO gas and additionair) on the intake manifold. The tests were divided into two cases:hybrid HHO/gasoline and HHO/gasoline with addition air from secondinjection. The experiments showed that, of both cases, compared tooriginal engine, the engine performance was improved and thegasoline fuel consumption was declined after enrichment of HHO gasand of HHO gas/addition air mixture,. The NOx emissionwas increased; however,, HC emission was reduced. The CO and CO₂emissions displayed different trends between the two cases. Whenonly HHO gas was injected, the CO emission surged due to richmixture, while it was decreased after supplying the addition air inthe second case. The CO₂ emission trend was in opposite directionof CO. The study demonstrated that the effect of HHO gas additionis most apparent at light loads and lean conditions
