WebThe HEUI injector allows for multiple injections at different metered rates. Using a staged fuel distribution ratio helps improve engine combustion which ultimately reduces emissions ouput. The electronic configuration was also more robust to offer better fuel management and electronic sensors into the engine. WebHydraulic pressure is used to build fuel pressure within the injector. What kind of fuel pressures can a HEUI injector build? 23,500 psi. Is injection pressure dependent or independent on engine RPM? Independent this means that high injection pressures can be utilized at low engine RPM's allowing for higher efficiency.
