Performance Assessment of Spark-Ignition Engine Combined with an HHO Generator

Abstract

This study investigates the performance of a four-stroke, spark-ignition engine equipped with a commercial HHO generator that utilizes tap water for HHO gas production. Employing adjustable voltage levels (15 V, 25 V, and 30 V), the generator’s impact on engine performance was assessed through experimental dyno tests, measuring torque, power, and fuel consumption, complemented by numerical analyses of HHO production and thermal efficiency. The results, comparing engine operation with and without the HHO system, aim to evaluate the HHO generator’s effectiveness as a fuel supplement for enhancing engine performance.
