Innovation for sustainability

Nottinghamshire-based Hardstaff Haulage has worked in partnership with Loughborough to bring a dual fuel injection system into the heavy goods vehicle (HGV) marketplace. Through this new system, 70 percent of diesel fuel used by a conventional HGV engine is substituted with natural gas.

The Hardstaff Group design, develop and supply low carbon dual fuel vehicle technologies that significantly reduce the carbon footprint in the road transport sector. Their Oil-Ignition Gas-Injection (OIGI®) system is a patented combustion technology that simultaneously burns two fuels – fossil or renewable natural gas (Biomethane) and diesel. Diesel is required as the ignition source and gas injection commences when speed increases from idle.

Hardstaff worked closely with the University’s School of Mechanical and Manufacturing Engineering on modelling gas flow and the simulation of dual fuel operation.

Further collaboration with the University, partly funded by emda (East Midlands Development Agency), has led to a state-of-the-art engine test cell being built at the Hardstaff headquarters. This will enable tests on multiple fuel and alternative fuel engines of the future and will validate engine performance, fuel economy and tail pipe emissions.

The pioneering work by Hardstaff Haulage and the University on the dual fuel injection system for HGVs was recognised with a prestigious Lord Stafford Award for Innovation for Sustainability. The awards celebrate innovative collaborations between business and universities.


The technology has reduced CO2 emissions by up to 20% and brought significant reductions in all other tail-pipe pollutants, compared to a conventional HGV engine.

Although the Hardstaff OIGI® system is currently being fitted to heavy goods vehicles, the technology is designed for a much wider range of application, with current sales through appointed distributors as far afield as Brazil.

As well as retrofitting the system, Hardstaff Haulage has been appointed as a specialist dealer by Mercedes Benz, which is supplying new vehicles to be fitted with the OIGI®.
