CHFA Technology

Combustion physics.
Not chemistry tricks.

NABL-certified results. Peer-reviewed research base. The science behind Earthion's Controlled Hydrogen Fuel Assist — explained plainly.

How It Works

Four steps. One result: more complete combustion.

Every diesel engine — no matter how well-tuned — burns 5–15% of its fuel incompletely. That waste exits as PM, CO, NOx, and CO₂. CHFA closes that gap without touching the engine.

01
💧
Water Electrolysis — On Demand
Distilled water passes through an alkaline KOH electrolysis cell. The cell splits water into hydrogen and oxygen (HHO) only when the engine is running — no HHO is generated or stored when the engine is off. Zero stored hydrogen. Zero explosion risk.
02
💨
Air-Intake Injection
The HHO gas is metered and injected upstream into the air intake — before the turbocharger on DGs, or into the air filter assembly on vehicles. It mixes with incoming combustion air. No engine modification. No drilling. No welding.
03
🔥
Leaner, More Complete Combustion
Hydrogen's wide flammability range creates additional ignition kernels inside the combustion chamber — reaching the unburned diesel pockets the diesel flame alone misses. The same fuel, the same engine, burning more completely. Less PM. Less CO. Less CO₂.
04
📊
GreenVision™ Live Monitoring
Every unit ships IoT-connected. Monitor HHO output, water level, electrolyte health, engine load, and fuel-efficiency delta in real time. Auto-generate ESG-grade tCO₂e and BRSR Scope 1 reports across your entire fleet or a single asset.
NABL Stack Test Results

The numbers. Not the claims.

Every figure shown here is from NABL-accredited, MoEF-recognised laboratory stack emission testing — identical load profiles before and after installation. Independent certification on every deployment.

  • No high-pressure hydrogen storage — generated on-demand from water only.
  • No engine modification. No fuel switch. Bolt-on retrofit only.
  • OEM warranty preserved. Independently validated across DG and vehicle platforms.
  • NABL-certified stack emission reports on every single installation.
Emission reductions — NABL stack test
Particulate Matter (PM)↓ 80.1%
NOx (as NO₂)↓ 59.2%
SO₂↓ 75.2%
CO₂↓ 42.9%
Fuel Consumption↓ 5–22%

System Architecture

Four subsystems. Engineered for continuous duty.

GreenDrive™ (vehicles) and GreenX™ (DG sets) share the same core CHFA architecture — scaled and calibrated for each application.

⚡

Validation & Certification
Every Earthion installation includes a NABL-accredited stack emission test at baseline and post-installation, conducted by independent MoEF-recognised laboratories — Neetal Labs, Ekdant Enviro, Lata Envirotech. You receive a certified report with exact before/after numbers. The technology draws on peer-reviewed research from 20+ institutions worldwide (ScienceDirect, Springer, MDPI, Nature Scientific Reports).

See it on your asset.

One DG or one vehicle. NABL-certified baseline. Post-installation measurement. The numbers before you commit to anything further.
