Background and Challenges

Global Fuelbox is an energy technology start-up company based in California. The firm tasked Nectar with developing a new fuel additive and delivery device for improving the miles-per-gallon (MPG) ratio of diesel engines, the primary power source for today’s trucking and transport industry.

Increasing MPG with Diesel Engine Fuel Additive Device

Nectar developed a comprehensive product requirements document for the new fuel additive device; conducted chemical and combustion engine research and Failure Modes & Effects Analysis (FMEA); and collaborated with external topic experts to design and engineer the required mechanical and electromechanical systems, and associated hardware and firmware. In addition to designing tests to meet MIL-STD 810, MIL-STD 461, and OSHA requirements, Nectar performed other tests recommended by the Society of Automotive Engineers (SAE).

Increasing MPG with Diesel Engine Fuel Additive Device

Improving Engine Performance No Easy Task

Global Fuelbox requested Nectar’s help in the development of a new fuel additive as well as a delivery system that could easily be fitted to existing diesel engines. Developing a new diesel fuel additive and engine delivery system required not only overcoming the inherent design and engineering challenges but also satisfying the requirements of regulatory agencies.

Improving Engine Performance No Easy Task

Improving Engine Fuel Usage and Performanc

Nectar delivered a functional diesel engine fuel additive device that both improved overall engine MPG performance and met all necessary regulatory requirements.


The firm delivered the first production units for the system on time and within budget, providing Global Fuelbox with the technology and product design that it needed to launch this energy technology start-up.
