HHO-Assisted Combustion, Dual-Fuel Gensets & Smart H₂ Flow Control

Followed By a Visit to Our Engine Research Laboratory

SYNOPSIS   

This talk presents Monash University Malaysia's ongoing hydrogen-fueled and hydrogen-assisted internal combustion engine (H₂ ICE) research, conducted in collaboration with industry partner Trident Nova Sdn. Bhd.

Three current projects are covered: an HHO-assisted light-duty diesel engine; a hydrogen–diesel dual-fuel engine for stationary power generation; and a novel auto-regulating flow valve for portable H₂ gensets.

Participants will gain insight into retrofit pathways, performance–emissions trade-offs, and techno-economic considerations for low-carbon power generation across both mobile and stationary applications.

Complementing the laboratory and on-going DOE runs, the second part of this talk presents lessons from live commercial fleet deployments across Malaysian long-haul and municipal operations. Field trials spanning Euro 2 to Euro 6 engine generations, across multiple makes and duty cycles, produced validated fuel efficiency improvements of 8 to 22 percent, with EGA-confirmed reductions in CO, CO₂, hydrocarbons, and particulate matter. A zone-based analytical methodology was developed to isolate HHO performance from operational variables including load variance, route profile, and fuel allocation practices. Dose-response confirmation established directional causality.

These findings bridge the gap between controlled laboratory conditions and real-world fleet economics and outline the commercial pathway from proof of concept to verified fleet decarbonisation at scale.
