The Technology

Technology Overview

G-volution has developed unique patented technology which can significantly reduce fuel costs and emissions on large diesel engines. 

G-volution technology focuses on three main areas:

  • Control: through the Optimiser, a device to control the delivery of one or more secondary fuels such as natural gas to co-combust with diesel by emulating the injection signal in the electronic engine control unit (ECU) fitted to the vehicle.  This now also enables one to three pulses of advanced injection to ensure greater combustion efficiency
  • Emissions:  GV is working with OEMs and a leading Tier 1 supplier to deliver dual fuel technology to Euro 6 standards
  • Injection:  GV continues to work with leading supplier of Natural Gas, and modelling technology, to deliver the most efficient but cost effective dual fuel combustion

The Company’s patented system enables the fuels to be delivered in constantly varying ratios dependent on operating conditions to optimise economic and emissions performance. 

The power output of the engine is unchanged and the operation is undetectable by the driver. 

There is no additional power or torque which could give rise to drive train damage. 

Crucially, this system of multi fuelling ensures that the ECU continues to operate as it was intended and on board diagnostic equipment is not affected.

Emissions Technology

Background :  GV has been sponsoring PhD work at a well-established UK University for 3 years.  This work has established a novel and disruptive solution for the effective catalysis of methane and other hydrocarbons  at low temperatures typical of a duel fuel engine.  This has not been commercially available to date.

Invention:  this invention, which is now patented, covers the following areas:

  • Chemistry:  a new type of Nano-catalyst has been developed which has been demonstrated to be effective at catalysing methane.  The structure is produced from metal-doped hydroxyapatite [patented] and can be manufactured with many different catalytically active metals, including nickel and palladium, offering a lower cost solution than traditional platinum based catalysts.
  • Structure:  a novel structure has been developed which offers a very high surface area subsequently increasing the space velocity and enhancing the catalysis process.  The structure can also be optimised to generate turbulent flow, again with the benefit of improved methane conversion.
  • Manufacturing:  through the use of novel additive manufacturing processes, the catalyst support can be manufactured in bespoke geometries (to suit system integration) in a cost effective and simple process compared to existing manufacturing techniques.
  • Testing:  initial tests indicate that these structures are very effective, and are also resilient to mechanical, thermal and chemical degradation over time.

Potential:  it is anticipated that this product will be able to offer Euro VI compliance on any dual fuel vehicle.  It also has the potential to replace the diesel oxidation catalyst in the existing exhaust system whilst retaining full emissions compliance.  The identified benefits are reduced system cost and complexity; simpler vehicle integration; and improved vehicle efficiency (through the reduction of back pressure).  These two elements, in the context of the GV business plan, means there is a clear immediate route to market, and a large market to target in and beyond dual fuel such as Syngas & Hydrogen generation.
