Isuzu now offers a range of commercial vehicles adapted to operate using a dual fuel option.
It’s a proven technology used globally, with over 14 million compressed natural gasses (CNG) vehicles operating in 80 countries.
Isuzu’s CNG-DDF (diesel dual fuel) technology has been thoroughly tested for reliability.
CNG offers significant benefits
- Reduced emissions: Isuzu CNG trucks emit 20-25% fewer greenhouse gases and virtually no harmful pollutants.
• Lower running costs: CNG is a cleaner-burning fuel, leading to reduced fuel consumption.
• Improved engine life: Less engine wear due to cleaner combustion.
• Quieter operation: CNG engines run smoother, resulting in less noise pollution.
• Faster refuelling: Compared to electric trucks, CNG ones’ refuelling are significantly quicker.
Easy to use
- Isuzu’s CNG-DDF system seamlessly integrates with the existing diesel engine.
• Drivers can switch between dual fuel (diesel/gas mix) and 100% diesel mode with the simple press of a button.
• The system automatically switches to diesel when the CNG tank is empty or detects a fault.
Performance and safety
- CNG trucks maintain similar torque, power and trip times as their diesel counterparts.
• CNG is lighter than air and disperses quickly in case of a leak, minimising risks.
• CNG has a narrow flammability range, making it statistically safer than conventional fuels.
Challenges and considerations
- Currently, CNG’s availability in South Africa is limited to Gauteng.
• CNG tanks add weight to the vehicle, slightly reducing payload capacity.
• CNG conversions are more suited for long-wheelbase models due to space requirements.
Strategic choice
Despite these challenges, CNG offers a strategic fuel option as volatile oil prices and environmental concerns make it a compelling choice for fleet owners. While the initial CNG network is limited, it is expected to expand in the future.
Isuzu’s CNG-DDF technology is available as an option for 20 long-wheelbase models. This allows for strategic fleet planning and a smoother transition to a cleaner future.
