Technology Principle
The principle explains how Hydroxy Gas is generated onboard and supplied to diesel intake with diesel remaining the primary fuel.
HOD TECHNOLOGY — HOW IT WORKS
Hydroxy On Demand: Hydrogen Technology Generated Onboard
Hydroxy On Demand (HOD) technology generates Hydroxy Gas onboard a diesel-powered vehicle or machine. The system uses electrical power and water to produce gas on demand, which is supplied to the engine intake. Unlike systems based on high-pressure hydrogen cylinders, HOD generates gas during operation. Compatibility and actual performance depend on the engine configuration, installation and operating conditions. Each application requires a technical assessment.
HOD Technology — How It Works
Water and electrical power generate Hydroxy Gas onboard a diesel vehicle or machine on demand. The gas is supplied to the engine intake rather than stored in high-pressure cylinders. Compatibility and performance depend on configuration, installation, operating conditions, and individual technical assessment.
01 Water and Electrical Power
Input resources for the onboard process.
02 Onboard Hydroxy Gas Generation
Hydroxy Gas generated on demand during operation.
03 Gas Supplied to the Diesel Engine Intake
Generated gas supplied into the diesel engine intake stream.
Sequential operating flow
04 Engine Performance Evaluation
Evaluation is performed against an agreed baseline and comparable operating conditions.

Technology FAQs
What is HOD?
HOD means Hydroxy On Demand: Hydroxy Gas generated onboard from water and electrical power as required.
How is gas generated?
Gas is generated onboard using water and electrical power during operation.
Does it use high-pressure storage?
The principle here is onboard generation and intake supply rather than high-pressure cylinder storage.
Can it be used on diesel engines?
The technology is intended for diesel applications, subject to technical assessment.
Is it universally compatible?
No. Compatibility depends on engine configuration, installation context, and operating conditions.
Are engine changes required?
Required installation details are configuration-specific and determined during technical assessment.
How is performance measured?
Performance is reviewed against baseline and comparable conditions using consumption and operational parameters.
Can it be applied to generators?
Generator applications are possible in principle, with case-by-case technical assessment.
