Large scale fleet

In South Africa, the vehicle conversion is king for Natural Gas run fleets! Any vehicle make-up of a fleet can be converted to operate on Natural Gas.

Running a fleet on Natural Gas is about key numbers. Comparing the running costs of a fleet on Diesel opposed to a fleet on Natural Gas, Natural Gas will win hands down, with the conversion costs factored in.

Fueling fleets

NGV operates 4 refilling stations for enroute refuelling and onsite mobile sister stations for large fleets. Refuelling and maintenance are easy to navigate and service technicians are available to assist with the technology. Natural Gas is in supply 24 7, 365.

Driven by global standards, the technology used to power the conversion is easily adaptable to all makes and models of fleet vehicles

Conversion costs vs long term savings

Converting a fleet to run on Natural Gas is commonplace in South Africa. Conversion centres have been in operation for over 10 years and many offer globally competitive pricing and service plans.

Natural Gas fleets work much like a Petrol or Diesel powered fleets. Natural Gas is stored in a fuel tank typically at the bank of the fleet vehicle.

The Gas is supplied in a high-compressed state and reduced to suite compatible pressure levels for any and all engine injection systems. Inturn the injection system will “feed” the fuel into the intake manifold or combustion chamber.

Fleet management

There are two key areas around the maintenance of a fleet running on Natural Gas:

Oil-Change Intervals

Natural gas tends to extend the useful life of the engine’s lubricating oil because it produces less carbon when burned. For fleets that have been converted from Petrol or Diesel to Natural Gas, it’s still best to follow the original maintenance schedule, particularly if the engine is under warranty.

Fleet managers may find it economical to send oil samples to the original conversion centre for testing, to understand the maximum useful lifetime for each oil change.

Ignition Systems

Natural gas is much more sensitive to spark quality and voltage. Therefore, it is critical that all parts of the ignition system (spark plugs, wires, coils, etc.) are properly maintained and protected from excessive heat and other damage.

We recommend that fleet managers should consult the maintenance manual for the proper interval for inspecting and changing ignition parts.

Note that some manufacturers produce spark plugs, ignition wires, and even engine oils that are specifically designed for use in NGVs. These will help to maximize the vehicle’s performance and engine life.
