You'll learn how to properly perform performance tests, evaluate spray patterns, and perform ultrasonic cleaning. Proper use of this tool allows you to extend the life of the engine and ensure its stable operation in any conditions.
Design features and functionality of the equipment
Stands Launch are complex electromechanical systems designed for comprehensive analysis of the condition of fuel injectors. The basis of the device is a high-precision pump that creates the necessary pressure in the line, and a control system that allows you to set different operating modes of the injector. The housing, as a rule, is made of durable materials that are resistant to aggressive chemical environments used as a working fluid.
The key element of the interface is the display and control panel, through which the operator sets testing parameters. Microprocessor system provides automation of processes, minimizing the influence of the human factor on measurement results. Depending on the model, the device can support different types of injectors, including mechanical, electronic and even direct injection (GDI) systems.
⚠️ Attention: When working with equipment, strictly ensure the compatibility of the liquid used with the seal materials of the specific stand model. The use of aggressive solvents can lead to swelling of rubber elements and leaks.
An important part of the design are measuring cylinders made of heat-resistant glass with clear graduations. It is from them that a visual assessment of the amount of fuel supplied and the quality of atomization is made. Some models are equipped with additional sensors that transmit data directly to the control screen, which increases diagnostic accuracy.
Always check the fluid level in the reservoir before starting a series of tests to avoid airing the system and loss of pressure.
Basic operating and testing modes
Functionality of modern stands Launch covers a wide range of tasks necessary for complete diagnostics of fuel equipment. The main operating modes are performance test, leak test, spray quality assessment and ultrasonic cleaning. Each of these modes requires specific settings and careful attention to detail.
Mode performance testing allows you to determine how many milliliters of fuel each injector delivers in a certain number of cycles or per unit of time. This is a key parameter for identifying clogged or worn sprayers. At the same time, the operator observes the shape of the torch: it should be cone-shaped, uniform and symmetrical.
- 🔍 Leak test: creating pressure in the system without sending pulses to open the valve to detect leaks.
- 💨 Spray test: visual assessment of the shape of the torch and the absence of drops on the sprayer cut after closing.
- 🧼 Ultrasonic cleaning: using cavitation to remove solid deposits inside the nozzle bore.
- ⚙️ Adaptation: selection of coefficients for new injectors in some advanced equipment models.
The cleaning mode deserves special attention. Ultrasonic bath, built into the stand or being part of it, creates high-frequency vibrations that effectively break up varnish deposits and carbon deposits. This process can take 15 to 30 minutes and significantly restores part throughput.
Step-by-step instructions for diagnosing injectors
The diagnostic process begins with preparing the equipment and removing the fuel rail from the vehicle. Carefully remove the injectors, being careful not to damage the electrical connectors and O-rings. Before installation on the stand, it is recommended to carry out an initial visual inspection for mechanical damage.
Install the nozzles into the sockets of the stand, making sure that they are securely fixed. Connect the electrical connectors according to the diagram if automatic control is used. Fill the tank with a special test liquid, which is similar in viscosity to gasoline or diesel fuel, but less fire hazardous.
☑️ Preparing for the test
Start the selected test mode via the control menu. Adjust the pulse parameters (opening duration, frequency) in accordance with the technical characteristics of the engine being tested. During operation, monitor the pressure gauge readings and the liquid level in the measuring cylinders.
Menu -> Test Mode -> Performance TestSet Cycles: 3000
Set RPM: 1500
Start
After completing the cycle, compare the volumes of liquid in the cylinders. The spread of indicators between the injectors of one engine should not exceed 5-10%. If one of the injectors shows significantly less volume, it requires cleaning or replacement.
Comparison table of popular Launch models
There are several modifications of equipment on the market, each of which is aimed at a specific segment of users. The differences relate not only to the number of injectors tested at the same time, but also to the type of injection systems supported, as well as the presence of additional functions such as an integrated wash.
The specific model you choose depends on the size of your operation and the types of vehicles you plan to work with. For specialized services for repairing diesel equipment, more powerful units with high pressure will be required, while combined solutions are suitable for universal service stations.
System type| Model | Number of channels | Ultrasound | Autotest | |
|---|---|---|---|---|
| CPC-101 | 4 | Gasoline | Yes | Yes |
| CPC-200 | 6 | Gasoline/Diesel | Yes | Yes |
| CPC-300 | 4 | GDI/Diesel | No (optional) | Yes |
| IFC-120 | 2 | Common Rail | No | No |
When choosing equipment, pay attention to the maximum operating pressure. For systems Common Rail and direct injection require significantly higher performance than for classical distributed systems. Compatibility of the software with current control protocols is also important.
Why is gauge calibration important?
The accuracy of pressure readings directly affects the performance test results. Over time, pressure gauges may become inaccurate, so it is recommended to periodically check their readings with a reference gauge.
Typical faults and methods for their elimination
During the operation of the equipment, various problems may arise related to both the stand itself and the injectors being tested. One of the common reasons for incorrect readings is air in the system or the presence of contaminants in the working fluid filter. Regularly replacing filters and fluid helps avoid many mistakes.
If unstable pressure is observed, check the tightness of the connections and the condition of the O-rings on the injector seats. Wear of these elements leads to leaks and the inability to create the necessary pressure for a quality test. Rubber seals should be changed after each series of intensive checks.
⚠️ Attention: Never leave working fluid in the system for a long time without use, especially if these are aggressive solvents. This can lead to corrosion of internal pump parts and lines.
If the ultrasonic module fails, check the integrity of the emitter and the liquid level in the bath. Operating without liquid or at low levels can lead to overheating and failure of the piezoelectric element. It is also worth checking the electrical contacts and fuses of the heater or frequency generator power circuit.
Maintenance and safety rules
Equipment durability Launch directly depends on the quality of its service. Regularly clean the outer surface of dust and fuel stains. The internal cavities and the sink bath must be washed with clean technical liquid after each use to prevent the deposition of contaminants.
Operator safety comes first. Work in a well-ventilated area as fuel and solvent fumes can be toxic. Use personal protective equipment such as gloves and goggles, especially when working with chemical cleaning compounds.
- 🛡️ Eye protection: mandatory when working under pressure to avoid liquid jets.
- 🧤 Gloves: protect skin from irritation and chemical effects of solvents.
- 🔥 Fire safety: There should be no open flames or sparking devices near the equipment.
- 🔌 Grounding: Make sure that the device is connected to a properly grounded network.
Periodically check the condition of electrical cables and connectors. Damage to the insulation can lead to a short circuit or incorrect operation of the control electronics. Preventive examination Helps identify potential problems before they cause failure.
Regular maintenance and compliance with safety rules guarantee a long service life of the stand and the accuracy of the measurements.

In addition, accurate diagnostics avoids situations where good parts are replaced by mistake. This increases customer trust and the reputation of the service. In a competitive environment, having your own fleet of remanufactured injectors or the ability to quickly check it becomes a serious advantage.
The cost of one diagnostic and cleaning procedure is significantly lower than the price of a new injector, which makes the service in demand among owners of cars with high mileage. Competent pricing and high-quality work ensure a stable flow of clients.
How often does the stand need to be calibrated?
It is recommended to check the accuracy of pressure gauges and graduated cylinders at least once a year or after every 1000 operating hours. For high-traffic services, this interval should be reduced to 6 months.
Is it possible to use gasoline instead of special fluid?
Strongly not recommended. Gasoline is too flammable, has low lubricity and evaporates quickly, which can disrupt the operation of the high-pressure pump and create an explosive concentration of vapors in the room.
What to do if the nozzle does not hold pressure?
It is necessary to carry out ultrasonic cleaning. If after 2-3 cleaning cycles the tightness is not restored and the spray pattern remains unsatisfactory, the nozzle should be replaced, as the shut-off valve or needle may be worn out.
