How electronic unit injector works. The central- injection unit operates at low pressure 07 to 1 bar so. An inexpensive hydrodynamic electric fuel pump can be used generally in the form an in-tank unit.

Hydraulic Electronic Unit Injection HEUI Watch later. The injector is flushed. The HEUI injector pressurizes supply fuel from 450 kPa 65 psi to 175 MPa 25382 psi.

Throttle Body Injection is an electronically controlled injection system in which an electronic fuel injector injects the fuel intermittently in to the intake manifold at a central point ahead of the throttle valve.

Electronically Controlled Unit Injector A3 or EUI-200 Lucas The unit injector is installed in the cylinder head above the combustion chamber. The ECU delivers an electronic signal to the fuel injector with the help of the electronic connection.

Each plunger moves through a fixed stroke under the action of the engine camshaft via a rocker arm and a. The HEUI injector functions as an atomizer by pumping high-pressure fuel through orifice holes in the unit injector tip. This video explains how gas patrol injector works.

Hydraulic Electronic Unit Injector HEUI C7 and C9 - Components. The spring-loaded plunger and barrel assembly to pressurize fuel inside the injector. 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.

The electronic unit injector is mechanically pressurized using the electronic control of metering timing and governing functions. Electronic signals from the ECU travel to one of two pins on the injectors. Closing the circuit is accomplished by the sending of a pulsing ground by the ECU to the injector.

ELECTRONIC UNIT INJECTOR EUI The Electronic Unit Injector EUI injects fuel directly into the combustion chamber. A unit injector consists of several basic elements. It consists of a range of basic elements such as the spring-loaded plunger and barrel to pressurize the fuel in the injector the poppet valve to regulate the pressure build-up an electric solenoid to actuate movement of the needle or poppet valve fuel inlet.

This activates the injectors solenoid which draws the magnetic top of the plunger opening the valves. The other pin is wired to the battery and through an ignition relay. How Electronic Fuel Injection Works.

How Electronic Fuel Injection Works - YouTube. Electronic unit injectors are mechanically pressurized using electronic control of governing timing and metering functions. Fuel feed and spill are through integral passages in the cylinder head into which the EUI body is sealed by high temperature O-rings.
