CAUTIONS

Warning

Since the test device is part of quartz glass, it is easy to break,

so do not place other objects around the equipment to avoid

bumping and breaking.

If there is no digital display after power on, please check

whether the power supply is powered; if so, check whether the

plug is connected firmly, or whether the fuse is blown. If it is not

broken, and the switch is still invalid after pressing the switch

several times intermittently, please contact the manufacturer

and must not disassemble it by yourself, otherwise our compa-

ny will not provide warranty.

When no cleaning agent is added to the ultrasonic tank, it is

strictly prohibited to open the ultrasonic cleaning item to avoid

damage to the ultrasonic system.

Every time the test solution is changed, it must be cleaned up,

and then 1L of new test solution should be added.

The use of unqualified testing agent will cause corrosion of the

oil pump, oil supply pipeline and failure of the pressure gauge.

Using other cleaning agent and testing agent will cause the

equipment surface coating to peel off.

It is strictly forbidden to use kerosene, gasoline or other testing

agent and cleaning agents as testing agent and cleaning

agents for this machine. Otherwise, the “O” ring and pipeline

rubber parts in the equipment will be damaged, causing

leakage.

The cleaning agent and testing agent should not be mixed up.

Before using the instrument, please read this manual careful-

ly for proper operation.

Fuel injector diagnostic and cleaning equipment is a mechatronics

product that combines ultrasonic cleaning technology and micro-

computer oil pressure closedloop control cleaning and detection

technology. This product simulates various operating conditions

of the engine, and cleans and inspects the fuel injectors of various

automobiles and motorcycles. This equipment is the necessary

and preferred equipment for the automobile and motorcycle repair

and maintenance industry, research and teaching and training

departments.

PRODUCT INTRODUCTION

Overview

Main

functions

Ultrasonic cleaning:

Ultrasonic cleaning can be performed on single or multiple

injectors at the same time, which can remove the attachments

and internal blockages on the injectors.

Uniformity detection:

To detect the uniformity of the injection volume of each injector.

Atomization observation:

Using the background light, you can observe the spray atomi-

zation situation of the nozzle in a comprehensive and careful

manner.

Tightness test:

It can detect the tightness and dripping of the fuel injector

under high pressure.

Fuel injection volume detection:

It can detect the fuel injection volume of the fuel injection

nozzle under specific working conditions (Such as the same

time and the same number of times).

●

Main features Using ultrasonic powerful cleaning technology, strong cleaning

ability.

Using electronic pressure regulating control technology, stable

oil pressure and wide adjustable range.

Use high-quality oil pump to ensure long-term stable use.

Technical

parameters

Design with HD color display, makes the operation clear and

easy to learn.

The oil tank liquid level is displayed visually, and the detection

liquid can be recycled.

Bright background light, you can clearly see the various

situations of the fuel injector when it is working.

It has replaceable composite joints suitable for a variety of

vehicle types.

Within the allowable adjustment range, the test time, working

frequency, fuel injection times, shortest switching period, etc.

of the fuel injector can be adjusted arbitrarily.

OPERATION PROCESS

Ultrasonic

cleaning

Ultrasonic cleaning is to use the penetrating and cavitation shock

waves generated when ultrasonic waves propagate in the medium,

and powerfully clean objects with complex shapes, cavities and

pores to completely remove stubborn carbon deposits on the fuel

injector.

Preparation

Remove the fuel injector from the vehicle and check whether

its rubber seal is damaged. If it is damaged, it should be

replaced in time before the cleaning test to avoid leakage

during the test. Then put the fuel injection nozzle into the

cleaning agent, carefully remove the external grease and wipe

it with a soft cloth.

Turn on the power and turn on the power switch on the side of

the main unit.

Put the cleaning bracket in the accessories into the ultrasonic

cleaning tank, and place the wiped fuel injector in the cleaning

bracket positioning hole of the ultrasonic tank.

●

Methods And Steps

Add an appropriate amount of cleaning agent to the ultrasonic

tank.

Insert the plugs of the drive wires into the injector sockets in

turn. (Special fuel injectors need to be connected with an

adapter cable)

Press the up or down key to select item 01 “Ultrasonic Clean-

ing” , and then press the function setting key to set the working

time.The default working time is 10 minutes, which can be

changed by up and down keys if needed.

Press START button, the system starts to feed pulse signal

and cleaning. After finishing cleaning, take out the injectors

from the ultrasonic bath, wipe the cleaning agent on them with

a soft cloth and prepare for the next item.

●

01 Ultrasonic Cleaning

NOTE

During the cleaning process, you can hear the intermittent

(approximately 5 seconds) vibrating sound when you take the

fuel injector out and put it to your ear, so you can judge whether

the fuel injector is working normally.

Ultrasonic cleaning is strictly prohibited when there is no

cleaning agent in the ultrasonic tank to avoid equipment

damage.

Only the ultrasonic cleaning agent dedicated to cleaning the

fuel injection nozzle can be added to the ultrasonic tank, and

other reagents cannot be used instead, otherwise any

malfunctions and damages caused will not be covered by the

warranty.

Injector

diagnostic

This function is to detect the atomization, dripping, blockage, fuel

injection angle status of the fuel injectors and the size and

balance of the fuel injection of each fuel injector at different

speeds.

Preparation

Confirm that the oil drain handle is open, use the funnel in the

accessories to add the test liquid to the equipment through the

glass window, and pay attention to control the flow rate during

the addition to avoid overflow.

Add 1 bottle (about 1000ml) of testing agent each time.

Install the fuel injector.

●

Select the top oil inlet connector from the accessories and

install it into the oil separator.

Install the fuel injector in the forward direction (apply a little

grease on the “O” ring of the fuel injector)

Put the horizontal end of the oil separator and the fuel injector

on the upper plate seat, and tighten the two ends with the

locking rod. Ready to test.

●

Methods And Steps

02 Idle Speed Test

Confirm that the injector to be tested has been installed

properly and the signal wire has been plugged in.

Select “02 Idle Speed Test”.

Press the function setting key to set the working time and pulse

width.

Press the start button to start work.
