How Does The System Work?
The heart of the system is the Cibus21 Green control unit, a unique, internationally patents pending technology, which works in harmony with the engine's own Electronic Control Unit (ECU).
The system monitors the amount of diesel burnt by the engine in normal use. A minimum amount of reagent necessary to create the maximum improvement in combustion efficiency is then introduced. This "Enhanced Combustion" releases more energy from the fuel with the immediate effect of less fuel being required.
The increased output generated by Enhanced Combustion is registered by the engine's ECU. Then the ECU responds by reducing the diesel supply, so that the performance drops back to its normal parameters. This means that the engine's ECU stays in control and continues to operate the vehicle within its normal performance limits.
​
​
Increased performance with lower emissions and improved fuel economy
Enhanced Combustion is fundamentally different to fuel replacement, whereas the majority of dual fuel systems operate on the principal of replacing 30-40% of Diesel fuel with a cheaper secondary fuel to create a fuel saving, the CIBUS21 system is a fuel saving, range-extending and harmful exhaust emissions reduction control technology targeted at heavy-duty diesel engines through the principal of Enhanced Combustion.

​
A simple bolt on solution /
Installed by Licensed Engineers
Installations are carried out by accredited gas technicians who are fully trained diesel fitters and/or automotive electricians.
The key components of the system are all of OEM quality and specially designed for these applications. All components comply with the strictest regulations and certifications. The Cibus21 System is a fully self contained unit, mounted on the host vehicle.
​
Applications
​
-
Logistic company HGV
-
Refuse and delivery vehicles in urban settings – emissions and efficiency gains
-
Military vehicles – operational and strategic mobility as well as performance gains.
-
Generators.
-
Construction and mechanical handling plant.
-
Marine engines – (not yet trialled)
-
Mining Industry
​
​
Liquid Petroleum Gas
-
Any secondary gaseous fuel can be used as the reagent, including: Liquid Petroleum Gas (LPG), Compressed Natural Gas (CNG), Liquid Natural Gas (LNG) and Methane. For convenience, the system currently uses Liquid Petroleum Gas / Propane.
-
The automotive use of LPG/Propane has an excellent International safety record.
-
All the components used are from leading branded suppliers and the work is carried out to the highest regulatory standards.
-
The enhancement effect itself is inherently safe, due to the small amount of gas being used - all it is used for is to make the diesel burn better.
-
The CiBUS21 Technology fitted to a diesel engine will automatically default to diesel only in the event of any malfunctions in the LPG/Propane system.

Propane
​
​
Refuelling
-
The time taken to refuel is similar to that of an ordinary diesel vehicle.
-
There is a well-established network of Propane / LPG re-fuelling points globally and a Bunkering Service will be available for bulk fuelling at depots for fleet users.
​
Insurance Backed Warranty
An insurance backed warranty is provided, which covers both the equipment and also the vehicle driveline.
​
Regulatory Points
-
The CIBUS21 technology is not a dual fuel system it is not a notifiable change to the engine of any given vehicle, this is because it defaults back to diesel should the CIBUS21 system installation suffer a failure for whatever reason.
-
The new CIBUS21 system is showing a gas/propane consumption of less than 5% ratio gas to diesel; this qualifies the gas management by CIBUS21 as an additive.
​
Purchase or Lease Facility
The system can be purchased outright or leased.

Return on
Investment
Automated Telematics from completed road trials demostrate:
* NORMAL TRUCK AVERAGE MPG 4.51 - 6.47
* CIBUS21 TRUCK AVERAGE MPG 5.4 - 7.8
Fuel Savings
This is an average fuel consumption reduction of 20%
A logistics operator with a fleet of 100 HGV trucks spends circa $10 million a year on fuel for the fleet.
Fitting the CIBUS21 system to these would save a gross sum in the region of $2,000,000 p.a. on this bill based on current data.
Improved
Performance
​
The vehicle will feel better to drive thanks to:
• An increase in low down torque/power which means that the vehicle "pulls" better.
• Less gear changes as the driver will go through the gears more quickly when accelerating and will not have to down-shift as often when pulling up gradients.
• Smoother driving
​
​
Longer Engine Life
and Reduced Maintenance
​
Rather than putting extra stress on the engine, by forcing it to operate at higher temperatures, the enhanced Combustion system should lead to a longer engine life with:
-
Lower core temperatures from the improved combustion
-
Less wear and tear due to the absence of soot in the engine and oil system.
-
Reduced maintenance of Diesel Particulate Filters through reduced emissions.

Testimonial
Emma, the driver, had 14 years’ service in the RLC driving everything from Landrovers to HETs and after leaving the Army she has worked for a number of haulage companies and is also serving as a reservist with 157(Welsh) Transport Regiment. Her report is shown below:
Driving the truck with gas input into the diesel improved the performance and handling of the truck when the vehicle is cold, you can actually feel improvement on the handling and not just that the pick up on the vehicle is a lot smoother and faster, the gear changes are much smoother and also the engine does not seem to be working as hard when pulling a load of 20 tons of sand.
The last couple of days from driving the truck I've felt a difference whilst driving the truck with gas on. I have also seen the improvements the gas has on the engine. I drove the truck from Newport on Monday morning with no gas input and after picking the trailer up in Leicester with the 20 tonne of sand the truck struggled on a slight incline, on Tuesday morning the gas was introduced into the diesel and from then on you could notice improvement on the performance of the vehicle. It also made it easier to handle on corners and easier to drive with and without a load.
​
I am sure companies and drivers will appreciate the benefits of the fuel savings and more comfortable drive it gives.
Many thanks
Emma.’
The Evidence
Early testing was carried out on rolling roads and on a variety of vehicles, and emissions were analysed by independent bodies. Over this period the software and control unit have been improved and efficiency gains increased. Since then ‘real world’ trials have been conducted with a major logistic company – these results proving to be even better than those on the rolling road.
