Uji Emisi dengan HESHBON 4-Gas Analyzer HG-520

Summary

This tutorial provides a step-by-step guide to using the HG 520 gas analyzer for vehicles running on gasoline. It covers the device setup, including turning it on, inserting the paper for the printout, and connecting the sampling tube to measure exhaust gases. Key metrics like CO, HC, CO2, and O2 are explained, with ideal values for proper fuel mixture and combustion. The process also includes instructions on printing the results with vehicle identifiers and shutting down the device safely. This guide is essential for accurate vehicle emission testing and analysis.

Takeaways

• 😀 The HG 520 Gas Analyzer is designed for 4-wheel vehicles running on gasoline, capable of measuring 6 gases, unlike the 2-gas model for motorcycles.
• 😀 To power on the device, switch on the back power switch and connect it to the power source. A beep sound indicates it's on, and it takes around 2 minutes to warm up.
• 😀 During the warm-up, insert the paper into the device by pressing the compartment button and positioning the paper with the front facing up.
• 😀 Ensure the vehicle's engine reaches a working temperature of 70-80°C before starting the measurement process.
• 😀 To measure the exhaust gases, connect the probe to the vehicle's exhaust pipe. The device will show the gas levels on the display during the process.
• 😀 The CO (Carbon Monoxide) level indicates fuel mixture efficiency. For EFI vehicles, the CO level should be under 1%.
• 😀 HC (Hydrocarbons) show the performance of the ignition system. For EFI vehicles, HC should ideally be under 100.
• 😀 CO2 levels indicate combustion efficiency. A CO2 level between 14% and 16% is ideal; values below 14% indicate exhaust leaks.
• 😀 After completing the test, press the 'print' button to generate a printed report, which can include vehicle plate numbers or exam numbers.
• 😀 The printed report shows the test results along with important vehicle details for documentation, especially for testing or exam purposes.
• 😀 After testing, disconnect the probe and press 'Escape' to shut off the pump. Once the pump stops, turn off the device to complete the process.

Q & A

What is the purpose of the HG 520 gas analyzer?

The HG 520 gas analyzer is used for testing the exhaust gases of gasoline-powered four-wheel motor vehicles.

How does the display of the HG 520 gas analyzer differ from other models?

The HG 520 gas analyzer has a display that shows data for six gases, compared to models for motorcycles which typically display only two gases.

What should be done before starting the HG 520 gas analyzer?

Before starting the analyzer, power it on using the switch at the back and wait for it to beep. Then, allow about 2 minutes for the warming-up process.

What is the proper procedure for loading paper into the gas analyzer?

To load the paper, press the release button, insert the paper with the front side facing forward, and then pull it through until it’s fully in place before pressing to trim it.

What is the significance of warming up the gas analyzer?

Warming up the gas analyzer ensures that the system is ready for accurate readings, with the display showing 'Span' and 'Zero' after the warm-up process is complete.

Why is it important to warm up the vehicle engine before using the gas analyzer?

The vehicle engine should be warmed up to a temperature of 70-80°C to ensure that the emissions are measured under normal operating conditions, which provides accurate results.

What is the role of CO (carbon monoxide) in the gas analysis?

CO is used to measure the completeness of the fuel combustion. It helps indicate whether the fuel mixture is perfect or if there are issues with combustion.

What is the acceptable CO level for an EFI (Electronic Fuel Injection) car?

For an EFI car, the CO level should be under 1%, which indicates proper combustion and an effective catalytic converter.

What does the CO2 reading indicate on the gas analyzer?

The CO2 level indicates the result of combustion. A CO2 value between 14-16% is ideal, with values lower than 14% suggesting a leak in the exhaust system.

What does the Lambda reading show in the gas analyzer results?

The Lambda reading measures the air-fuel ratio, with a ratio between 14-15 being ideal for optimal combustion efficiency.

How do you print the results from the gas analyzer?

To print the results, press the 'Print' button, and the data, including vehicle or student ID numbers, will be printed on a paper. This serves as proof of the emissions test.

What should be done after printing the results from the gas analyzer?

After printing, disconnect the sampling probe and power off the analyzer by pressing the 'Escape' button. Once the pump has stopped, you can then turn off the power.
