The Air and Methane gas mixture is compressed

As the piston reaches TDC

a reduced amount of diesel

is injected into the cylinder

The air and methane gas

Hardstaff OIGI® (Oil-Ignition Gas-Injection) Dual Fuel Hardstaff OIGI® (Oil-Ignition Gas-Injection) Dual Fuel Vehicle TechnologyVehicle Technology

Electronic system that reduces the amount of diesel injected into a cylinder, replacing the fuel with natural gas or bio methane, without affecting power and characteristics of the original diesel engine.

o OIGI® Dual Fuel is a patented combustion technology that simultaneously burns two fuels - natural gas or biomethane and diesel.

o Sequential gas injection, metered on a cylinder by cylinder basis.

o Diesel is required as the ignition source.

o The engine will use 100% diesel at idle; gas injection and diesel reduction commences when engine speed increases from idle.

The OIGI system uses cylinder by cylinder gas substitution strategy

oNo change to original engine power or torque

oSeamless transition between Diesel and Dual Fuel modesoImproves Driver acceptanceoNo impact of application of vehicle

oImproved fleet integration

oProven reliable system is accepted by a number of OEM’soSeamless warranty and service provision

oNo added risk for the operator / owner

oReliable and non-invasive technology platformoAcceptable to fleet managers and technicians

oEase of acceptance by operators, technicians and fleet management enables wider fleet adoption

oHighest possible rates of gas substitutionoMaximizes reductions in diesel consumption

oMaximizes financial and environmental benefits

Reduced Legislated EmissionsoCleaner tail pipe emissions is a business differentiator

oDrives new business, win contracts with environmentally conscious clients

oInherent reductions in Particulate Matter (PM)oReduces balance point performance of DPF technologies

oReduces associated service costs

oPotential exemption from Low Emission/Congestion area restrictions

oMay remove the need to install exhaust after treatment

Reduced CO2 Emissions and ability to operate using BiomethaneoCarbon footprint – a significant business driver within major corporate and

governmental customersoOpens doors to new business and meets requirements of existing customers

Dual Fuel Substitution Vs CO2 Reduction

Reduced CO2 Out Put In Dual Fuel Mode

o As substitution rates increase CO2 reductions increases

o With average substitution rates of 55%-65% CO2 output will be reduced by 15% to 18%

o 18% to 22% CO2 reductions In regional haul and over the road applications
