Once your vehicles have been specified and ordered, you should review your fleet operations in preparation for fleet delivery and ongoing support. This section will provide information to help you prepare for the arrival of your natural gas vehicles.

For a return to base fueling strategy involving the design and construction of a CNG fueling station, it’s important to know the inlet pressure of the gas delivered  to your location. Your local natural gas provider can supply this information. Typically, higher inlet pressure will reduce the amount of compression required. Time-fill systems will require less compression capacity than fast-fill systems.

If you’ll be accessing a public fuel station, it’s important to develop a fueling strategy to manage the fleet’s operation.  Here are some items to consider:

  • Where will the vehicle refuel enroute – a dedicated source? Public? Private?
  • What time of day will you refuel and how long will it take to fuel each vehicle?
  • Will there be waiting times at the station?
  • Is the location accessible for trucks?
  • Can a CNG station fuel a truck to capacity?

Whether you choose LNG, CNG, or RNG, training your staff on the proper and safe handling of fuel station equipment will be required. Contact your fuel provider for more information.

Service requirements for natural gas engines, while similar to diesel, are also different. Cummins requires technicians to be certified to maintain and repair Cummins Westport natural gas engines.  To specify training requirements, determine the service strategy for the fleet. Who will be doing scheduled maintenance? Who does warrantable repairs, if necessary?

Cummins Westport engines require specific parts, tools, and natural gas engine oil. If your service plan involves using local dealers, confirm that the local service provider can service vehicles within your fleet’s operating range, and is an authorized Cummins service provider.

We recommend that you review engine service intervals and maintenance best practices recommended in your Owner’s manual.  Set service intervals by recommended hours and average fleet speed as shown in the Payback Calculator.

For more information, refer to the CWI Natural Gas Academy. You’ll find a comprehensive range of information and videos related to engine, vehicle, and fuel related operations.

If your fleet will be self-servicing, review facility requirements and understand what is required for basic engine maintenance vs. fuel system or vehicle related maintenance.  Following recommended maintenance practices will ensure success.
