The electronic control system is integrated into the engine's fuel system and intake and exhaust systems to electronically control the fuel injection amount and timing. Compared with traditional mechanical engines, the electronic control system provides enhanced timing control and air-fuel ratio control. The injection timing is achieved by precisely controlling the injection time of the injector. The engine speed is controlled by adjusting the injection duration. The ECM starts the fuel injection process by energizing the single injector solenoid valve. Similarly, the ECM de-energizes the single injector solenoid valve to stop injection. ECM uses a personality module to store all rating information for a specific application. Personalized modules cannot be physically replaced. Must use computer flash personality module. See System Operation, Testing, and Tuning the Fuel System for a complete explanation of the fuel injection process. The engine uses the following types of electronic components:

The engine uses the following three electronic components:

• Input parts

• Control unit

• Output parts

Input components are components that send electronic signals to the system ECM. The transmitted signal changes in one of the following ways:

• Voltage

• frequency

• Pulse Width

The signal changes in response to changes in certain vehicle system parameters. Some specific examples of input components are an engine speed-timing sensor, a coolant temperature sensor, and a cruise control switch. The ECM interprets the signals from the input components into relevant operating conditions,

Environmental or engine operation information. The control unit receives an input signal from the input unit. The electronic circuit inside the control unit evaluates the signal from the input unit. These electronic circuits also provide power to the output components of the system. The power supplied to the output component is based on a preset combination of input signal values.

Output components are components operated by the control module. The output unit receives power from the control assembly. The output unit uses this power in the following two ways. The output component can use this electrical energy for work. The output component can use this electrical energy to provide information. For example, a moving solenoid valve plunger can do the work. By doing work, the component performs its function in order to regulate the engine. For example, dashboard lights or alarms provide information to the engine operator.

These electronic components have the ability to electronically control the operation of the engine. Engines with electronic controls have the following advantages:

• Improved performance

• Improved fuel consumption

• Reduced emission levels

Introduction

The working principle of the hydraulic electronic single fuel injector system is different from other fuel systems using mechanical drive. The HEUI fuel system requires no adjustments. Adjustment of mechanical parts cannot be performed. By installing different software in the electronic control module (ECM)

Change performance.

This fuel system consists of the following four basic components:

• Hydraulic electronic control unit fuel injection pump (HEUI)

• ECM

• Monoblock injector hydraulic pump

• Pump

Note: The oil transfer pump is a serviceable part. The internal parts of the HEUI fuel system are not serviceable.

Component description

Hydraulic electronic single fuel injector

Typical example

The fuel system uses hydraulically driven electronically controlled single-unit injectors. All diesel fuel systems use a plunger and plunger to pump high-pressure fuel into the combustion chamber. HEUI uses high pressure

Oil to drive the plunger.

HEUI uses high pressure engine oil from 6 MPa (870 psi) to 28 MPa (4061 psi) to pump fuel from the injectors. high

Press oil is called fuel injection drive pressure. HEUI works the same way as a hydraulic cylinder to double the force of high-pressure engine oil. This pressure multiplication is achieved by applying high-pressure engine oil to the piston. The piston is about six times larger than the plunger. The piston is driven by the high-pressure engine oil to push the plunger. The oil driving pressure generates the injection pressure of the single fuel injector. The injection pressure is about six times greater than the oil drive pressure. Low oil drive pressure produces low fuel injection pressure. High oil drive pressure produces high fuel injection pressure.

ECM

The ECM is located on the left side of the engine. The ECM is a powerful computer that provides overall electronic control of engine performance.

ECM uses multiple sensors to collect engine performance data.

ECM uses this data to adjust fuel delivery, injection pressure, and injection timing. The ECM includes programmable performance maps (software) to determine power, torque curves, and speed.

The ECM is responsible for recording engine performance failures. When ECM is used with electronic repair tools, ECM can also run several diagnostic tests automatically.
