Evolving the fossil fuel petrol fuelled range extender engine of the TX and VN5 to use compressed natural gas (CNG), biomethane, liquefied petroleum gas (LPG) and biopropane.
Using the same Prins Alternative Fuel Systems VSI-3 hardware these vehicles can also adopt net zero carbon emission renewable fuel biomethane (replaces CNG) and net zero carbon emission renewable fuel biopropane (replaces LPG).
Biomethane and biopropane are ‘drop in’ replacement fuels for CNG and LPG. No further vehicle changes are required to adopt these fuels in place of CNG and LPG.
Adopting these fuels in place of fossil fuel petrol offers:
CNG
20% lower carbon emissions
LPG
10% lower carbon emissions
Biomethane
99% lower carbon emissions
Biopropane
99% lower carbon emissions
Operating cost savings
30-50% lower for these fuels versus using petrol.
Further cost savings are possible as biomethane and biopropane production volumes continue to ramp up.
CNG, LPG, biomethane and biopropane are all available TODAY and can be adopted in place of petrol.
Internal Combustion Engines (ICEs) don’t need to use fossil fuels and can evolve and transition to adopt lower carbon alternative fuels of CNG and LPG and net zero carbon emission renewable fuels of biomethane and biopropane.
The LEVC TX and VN5 vehicles’ operating ranges, when powered by the range extended engine, are increased by ~90% (LPG/biopropane) and ~70% (CNG/biomethane) following the installation of the bi-fuel system since the original petrol tank is also retained.
System Hardware
Engine bay of a bi-fuel LPG/biopropane LEVC TX/VN5
For CNG/biomethane the engine bay layout is similar. However in place of the LPG / biopropane vapouriser, a CNG / biomethane pressure regulator is fitted instead.
The bi-fuel evolution uses Prins Alternative Fuel Systems VSI-3 system.
This includes:
Fuel tanks for LPG / biopropane or CNG/ biomethane
Bi-fuel ECU which works alongside the original LEVC engine ECU
LPG / biopropane fuel vaporiser (warmed by engine coolant)
Or a CNG pressure regulator (warmed by engine coolant)
Gaseous fuel injectors
Fuel gauge / switch in the vehicle cabin
These components meet the R67 (for LPG/biopropane) or R110 (for CNG/biomethane) standards and the overall design meets the R115 standards.
50 litre LPG / biopropane tank in the boot of the TX
40 litre CNG / biomethane tank installed in the LEVC TX. Two 40 litre CNG / biomethane tanks can be installed in the LEVC TX.
Prins CNG/biomethane pressure regulator.
Prins fuel gauge / switch installed on the accessory bar of the LEVC TX
