    Mechanical fuel injection, 'K' stands for German: "Kontinuierlich", meaning continuous.Commonly called 'Continuous Injection System (CIS) in the USA. K-Jetronic is different from pulsed injection systems in that the fuel flows continuously from all injectors, while the fuel pump pressurises the fuel up to approximately 5 bar (73.5 psi).

  6. Pintle injector - Wikipedia

    en.wikipedia.org/wiki/Pintle_injector

    The pintle injector is a type of propellant injector for a bipropellant rocket engine. Like any other injector, its purpose is to ensure appropriate flow rate and intermixing of the propellants as they are forcibly injected under high pressure into the combustion chamber , so that an efficient and controlled combustion process can happen.
