Electronic Unit Injector Operation

Adjustments to the components that are mechanical can not be made. The HEUI fuel system is completely free of adjustment.

Conventional Fuel Supply Systems in diesel engines require high-pressure lines to deliver the pressurised fuel into the injectors.

Electronic unit injector operation. The throttle unit resembles a carburetor except that there is no fuel bowl float or metering jets. Delphi E3 Diesel Electronic Unit Injector High speed dual valve operation for accurate control of injection events High pressure injection for optimized combustion and reduced aftertreatment Lightweight compact design for enhanced efficiency Available with a wide range of high pressure nozzle options Multiple injection capability with programmable shot-to-shot injection control Programmable. ELECTRONIC UNIT INJECTOR EUI The Electronic Unit Injector EUI injects fuel directly into the combustion chamber.

Adjustments to the components that are mechanical can not be made. Unit injectors use a plunger and barrel to pump high pressure fuel into the combustion chamber. We at Engineered Diesel created this video to help our customers have a better understanding of how a common rail diesel injector works which makes it eas.

The small size of the injector along with the trapezoidal valve placement in the cylinder head allows the EUI to be placed in the center of the combustion chamber for optimal fuel efficiency and low emissions. Electronic unit injectors are mechanically pressurized using electronic control of governing timing and metering functions. Electronic Unit Injector The requirement for more flexible control of injection parameters gave rise to a new form of unit injector called the electronic unit injector in which the traditional P-L-N pumping element design has been replaced by a plain plunger and a high speed electromagnetically solenoid operated spill valve.

Fuel is sprayed directly into the throttle bore s by the injector s. The spring-loaded plunger and barrel assembly to pressurize fuel inside the injector. And Delphi has a thorough understanding of markets around the world and a global network of resources.

The operation of the Hydraulic Electronic Unit Injector HEUI fuel system is completely different from any other type of fuel system that is actuated mechanically. A type of electronic fuel injection system that uses a single injector or pair of injectors mounted in a centrally located throttle body. The Delphi E3 Diesel Electronic Unit Injector EUI is one of the worlds most advanced production diesel unit injectors for high performance heavy duty applications.

A unit injector consists of several basic elements. It is driven by the engines overhead camshaft with one EUI per cylinder. Compartilhar conhecimentos Mecânicos.

Pre-injection Injection End of injection and Fill. This is a short promo of AutoMates automotive training module covering HEUI - the precursor to the Common Rail Diesel engineGet Better Training - visit htt. Operation of the Electronic Unit Injector The operation of the Electronic Control Unit EUI consists of the following four stages.

The HEUI injector serves four functions. The HEUI injector delivers the correct amount of atomized fuel into the combustion chamber. The operation of the Hydraulic Electronic Unit Injector HEUI fuel system is completely different from any other type of fuel system that is actuated mechanically.

The HEUI injector pressurizes supply fuel from 450 kPa 65 psi to 175 MPa 25382 psi. The HEUI injector functions as an atomizer by pumping high-pressure fuel through orifice holes in the unit injector tip. The HEUI fuel system is completely free of adjustment.
