GUARDIAN HYDROGEN DIESEL SYSTEM
Reduce your carbon footprint with your existing fleet today!
Injecting Hydrogen Intelligently
Cleans Emission Systems
Hydrogen Acts as a catalyst much like the DEF fluid we use today. The Cleaner combustion that hydrogen creates also actively reduces the amount of unburnt fuel entering the Emission system.
Cost Effective Solution
Allows you to retro fit the existing tier 4 diesel engines in your fleet, thus reducing your GHGs.
Retrofit For Existing Engines
The Guardian Hydrogen Diesel system is very non-invasive to the factory engine and allows for you to retain all factory components of the engine and emission systems.
Injecting Hydrogen Intelligently
As the world transitions to low-carbon energy sources, the headwinds facing the trucking industry are numerous and significant. At the top of the list are the regulations to lower the emission of CO2, NOx, SOx, and Particulate Matter. In addition to the lower emission requirements, fleets must also ensure they maximize their existing fleet capital before looking at replacing either engines or trucks. By ensuring low emissions and high capital efficiency, innovative and environmentally conscious trucking fleets can build a competitive advantage during bidding and procurement processes with their clients.
Why Choose DTI?
Diesel Tech Industries is a trusted and well established company with over 20 years in the transport industry Technology field.

Our mission is rooted in driving innovative technology to the transportation industry, with focus on diesel engine applications. All of the Guardian products are based on the same principles. Gathering engine data, interpreting it, and providing an action. In this case adding hydrogen as a second fuel source into the combustion engine. This same base technology is being used on the Guardian Hydrogen Diesel System, making us once again, a leader in the transportation technology industry.
The Guardian Hydrogen Diesel System is being developed and engineered in-house by our technical experts. We are working alongside people with practical industry expertise.
Your device is backed up through a secure cloud based system and also physically stored on the device. Data is accessible 24/7 on multiple platforms and uploaded automatically.
Low Carbon Intensity Hydrogen - this is a key part of the economics so we are ensuring that Hydrogen is being blended at optimal ratios for performance and emissions.
Key Components

Identified Problem
• Regulatory requirements to reduce greenhouse
emissions by 2030 and down to net-zero by 2050.
• Existing fleet economics, or sunk capital, before looking at replacement of their engines or tractors.
• Guardian HDS will help fleets with the energy transition and ensure competitiveness for themselves and their clients.


Efficiency of Engine
The data beside is based on a Volvo D13 in a Long Haul Class
8 application, traveling 300,000 km per year.
There are two different numbers at play when DTI talks
about the efficiency of the engine.
Mass Replacement – This is referring to the actual amount of
diesel that is being replaced by hydrogen. If the target mass
replacement is 20% per 100L of diesel, then 20L of diesel would
be replaced with 6.2kg of hydrogen.
Efficiency of Engine – The addition of hydrogen in a diesel
engine allows for a more complete combustion of diesel and
reduces the build up of carbon in the engine. Replacing diesel
with hydrogen will allow the engine to travel the same distance
while consuming less diesel.
