Electronic Unit Injection System
The throttle unit resembles a carburetor except that there is no fuel bowl float or metering jets. The unit pump injection system UPS injects the fuel into the engine cylinder.

The HEUI injector serves four functions.
Electronic unit injection system. As we have discussed the Petrol injection system in the modern engines In which the fuel injection system uses the sensors a computer and a solenoid operated fuel injector to meter and inject the right amount of fuel into the engine cylinder called the Electronic Fuel Injection system EFI. The unit injector system UIS is a nozzle. The HEUI injector functions as an atomizer by pumping high-pressure fuel through orifice holes in the unit injector tip.
The spring-loaded plunger and barrel assembly to pressurize fuel inside the injector. Hydraulic Electronic Unit Injector HEUI C7 and C9 - Components. The hydraulic electronic unit injectors use high pressure engine oil to provide the force needed to complete injection.
An engine camshaft drives the injector typically through the rocker lever resulting in an efficient mechanical and hydraulic fuel system that can minimize parasitic losses. It consists of an electronically controlled unit pump and a nozzle holder assembly connected via a precisely adapted high-pressure line. A system which aims at optimizing fuelair ratio entering a vehicles engine is referred as Electronic Fuel Injection System.
A Servojet electronic fuel injection system was designed and manufactured for the Cummins VTA-903 engine. EFI System has almost completely replaced usage of carburetors. A type of electronic fuel injection system that uses a single injector or pair of injectors mounted in a centrally located throttle body.
Fuel is sprayed directly into the throttle bore s by the injector s. An electronic unit injector system is installed directly into a cylinder head over every combustion chamber. Injector nozzle breakage and leakage problems were solved.
Electronic unit injectors are mechanically pressurized using electronic control of governing timing and metering functions. Fuel droplet sizes are smaller for enhanced emissions and this finer atomization enables EGR flow tolerance into. The system consist of a common rail or distributor pipe.
Installing different software in the ECM makes. A unit injector consists of several basic elements. The HEUI fuel system requires no mechanical adjustment.
A gear driven axial pump raises the normal pressure to the. This is a short promo of AutoMates automotive training module covering HEUI - the precursor to the Common Rail Diesel engineGet Better Training - visit htt. Electronic Fuel Injection System In Diesel Engines Modern diesel engine use common rail injection system to comply with emission regulations and increase performance.
These systems use the electrical and electronic systems to monitor and control. High pressure pumps pressure regulating valves injectors electronic control unit and associated sensors to assist. HYDRAULIC ELECTRONIC UNIT INJECTOR HEUI FUEL SYSTEM The operation of the HEUI fuel system Figure 3 is different from mechanically actuated fuel injection systems.
Many of the mechanical drive components found in standard mechanical or electronic unit injection systems are not used in this system. This system consists of the unit injectors fuel manifolds electronic pressure regulator high pressure fuel pump electronic control unit wiring harness and engine sensors. The HEUI injector pressurizes supply fuel from 450 kPa 65 psi to 175 MPa 25382 psi.
The electronic control unit provides the electrical signals to the injectors to control the solenoid valves at the proper times to obtain the desired injection timing and the desired quantity of fuel for a particular engine operating point. 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. 1 Introduction to Electronic Fuel Injection System.
A solenoid on each injector controls the amount of fuel delivered by the injector. Electronic Fuel Injection System.
