Nostrum for Commercial Fleets

Fuel costs represent 37 percent of a fleet’s operating expense. Nostrum’s technologies and combustion systems significantly enhance the amount of energy that reaches a vehicle’s wheels from the engine and dramatically improves tailpipe emissions for a more environmentally friendly fleet. Improved efficiency means significant cost savings for commercial fleets such as parcel delivery and long-haul truck organizations, public transportation, as well as refuse management companies, private transportation and the military. Contact us for more information about our fleet products launching in 2017.

Nostrum for Original Equipment Manufacturers (OEMs)

The advanced science and technology in our K-DI™ and K-ITI™ products can enable significant reductions in fuel consumption and emissions, without requiring an entirely new engine infrastructure. These reductions can be pushed even further with our dilute combustion system concepts. As fuel efficiency standards demand greater and greater improvements, Nostrum’s product portfolio provides solutions to meeting these standards without needing a significant shift in consumer behavior.

Fuel Injectors

As the adutomotive industry transitions to more complex fuel injection systems, such as high-pressure gasoline direct injection, original equipment manufacturers (OEMs) and the high performance aftermarket will require science-based, technology solutions to address broader engineering and marketplace demands. Nostrum injectors and dilute combustion systems are uniquely positioned to provide superior solutions for future OEM and current aftermarket engines.

The high flow Kinetic Gasoline Direct Injection (K-DI™) injector will be available in early 2016. The injector has been designed to work with existing engines so the manufacturing infrastructure required to build new engines does not need to be modified at all, saving the automotive industry hundreds of millions of dollars. The injector is also designed as a direct fit option for both high performance and fuel efficiency aftermarket applications.

Kinetic Gasoline Direct Injection (K-DI™)
direct injection

  • Proprietary kinetic particle break-up mechanism with patented nozzles provide smaller droplet sizes, superior fuel atomization, accurate controllability, and shorter liquid lengths versus leading conventional injectors
  • High flow, high performance applications (high flow rates)
    • Nostrum K-DI™ injectors deliver flow rates of up to 35 grams per second, more than twice the average stock flow rate of 14.7.
    • The first Nostrum products for 2.0L Ecotec turbo engines flow approximately 21g/sec and can fuel more than 800hp, while still providing excellent fuel vaporization and good quality combustion.
  • Application specific spray targeting to meet the needs of each engine’s combustion system
  • Nostrum K-DI™ injectors offer plume angle ranges from 35 to 110 degrees and plume targeting angles from 0 to 35 degrees, enabling cleaner, more efficient combustion to produce more power safely and with control. There are no other aftermarket high flow injectors that offer this capability for direct injection.
  • High-flow K-DI™ injectors are the only aftermarket injectors to allow liquid lengths 30 to 40 percent shorter than conventional multi-hole injectors. This helps minimize wall impingement and oil dilution to provide cleaner and more efficient combustion. There are no other aftermarket high flow injectors for direct injection that offer these types of short liquid lengths.
  • Fuel efficiency applications (stock flow rates)

Kinetic Water Injectors (KiWi™)

Nostrum Energy’s water injection technology with patented kinetic particle breakup nozzle is the unique proprietary injector designed to meet the extreme challenges of water injection. Nostrum’s diluent injectors improve atomization enabling the reduction of the amount of water used. This in turn maximizes the benefits of charge cooling and dilution as well as minimizes any of the negative aspects that have been issues with prior efforts, such as oil dilution and component damage.

KiWi™ Direct Water:

High pressure, direct in-cylinder water injectors.

KiWi™ Port Water:

Low and medium pressure, water injectors for intake track locations (single, multi and port).

The standard internal combustion engine found in most automobiles operates on the same system developed in the 1800s. Taking lessons learned from outside the automotive industry, Nostrum has created an advanced system to help unlock the true potential of an engine, the Nostrum CycleTM and Mulye CycleTM. These add two distinct applications of water to the normal combustion cycle to boost performance and efficiency through “dilute combustion systems.” The advanced science powering the Nostrum Kinetic Direct Injector (K-DITM) and Kinetic Intake Track Injector (K-ITITM) makes this direct water injection possible.

Nostrum dilute combustion systems are uniquely positioned to provide superior solutions for future OEM and current aftermarket engines. Applications of the Nostrum CycleTM and Mulye CycleTM dilute combustion systems can enable the next generation of high brake mean-effective pressure (BMEP) engines to achieve unprecedented levels of efficiency. These revolutionary new approaches work with spark ignition gasoline and natural gas engines, as well as compression ignition diesel and gasoline engines.

Nostrum CycleTM / Mulye CycleTM (The Internal Combustion Cycle + Water)

  • Water is injected directly into the combustion chambers, via K-DITM technology, to manage peak temperatures and provide knock mitigation, allowing the engine to operate at Mean Best Torque (MBT) ignition timing at all loads.

  • In alternate applications for aftermarket integration and for first-step implementation, water is injected into the intake track, via K-ITITM technology, to manage peak combustion temperatures and provide knock mitigation for high combustion pressure applications (boosted and/or high compression ratio)

  • Enabling higher combustion pressures with the Nostrum CycleTM and Mulye CycleTM directly increases the thermodynamic efficiency of the combustion cycle, while mitigating potential harmful emissions such as NOx and PM levels for diesel engines.

  • The Mulye CycleTM evolves the water-infused Nostrum CycleTM to lean-burn conditions, mitigating in-cylinder nitrous oxides to substantially improve internal engine cooling, enabling lean-burn for real world commercial applications.

  • Correct application of the Mulye CycleTM makes it possible to eliminate the external cooling loop by providing complete internal temperature control and hardware thermal protection.

Results of the Nostrum CycleTM / Mulye CycleTM

  • On a heavy duty commercial, natural gas engine, such as an electrical generator used in stationary power: 15 percent improvement in engine efficiency.


  • On a regular 2.4L gasoline engine, such as a family sedan: 220 g/kWh (grams per kilowatt-hour) minimum brake specific fuel consumption (BSFC) providing 4.5 percent improvement in efficiency and a 70 percent reduction in nitrogen oxides (pollutants) at high BMEP (brake mean effective pressure) and engine speed.


  • On a 1.9L TDI diesel engine, such as a European sedan: 95 percent reduction in nitrogen oxides (grams per kilowatt-hour), 33 percent reduction in particulates and 8 percent improvement in efficiency in optimized water injection (Water %) and exhaust gas recirculation ratios (EGR %)


Kinetic Injectors (K-DITM / K-ITITM)

  • Proprietary kinetic particle break-up mechanism with patented nozzles designed to meet the extreme challenges of water injection.
  • Advanced injectors deliver significantly reduced liquid lengths and superior vaporization rates, and enable application specific spray targeting to meet the needs of each engine’s combustion system.
