Kinetic Water Injectors (KiWiTM)

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.

KiWiTM Direct Water:

High pressure, direct in-cylinder water injectors.

KiWiTM Port Water:

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

Kinetic Water Injection

Patented kinetic particle breakup mechanism nozzle that delivers improved atomization, significantly reduced liquid lengths, and superior vaporization rates.

Operating Pressure: Low (4bar) to high (250bar) pressure systems.

Spray targeting capabilities: Up to 103 plume widths and up to 35 targeting angle; split plume and special plume cross sections.
