Introduction

This is an experimental report to measure the effectiveness of O2 BAND.

This is a report that shows the results of the positive changes in engine combustion when O2 BAND was on detached.
We categorized the process as four.

1. Exhaust Gas component measurement.
2. Exhaust measurement.
3. Measurement of the engine vibration.
4. Fuel efficiency change measurement

The purpose of this test is to check the performance of O2 BAND and compare the changes in Exhaust gas components with four categories.

Summary

This report summarizes the results of the four test measurements on the introduction.The measurement values are summarized as follows.

1. ( Fuel efficiency measurement )
Total 3 vehicles were used on the test. Tester tested approximately 15 km or more and compared fuel efficiency value.
(Test circumstance proceeded unequipped/equipped O2 BAND.)
The table below shows the change of fuel efficiency (unequipped/equipped) of the O2 BAND.

As the test showed, an average of 45.9% was increased when the O2 BAND was installed.

Although there were differences between each vehicle, we can see fuel efficiency improved when O2 BAND was installed.

2. ( Exhaust gas composition measurement )

Tester measured exhaust gas composition of value change depending on O2 BAND were equipped/unequipped.
The average value data was calculated by 6 cycles (12 times). Based on two test methods.
Tester measured exhaust gas composition of value change depending on O2 BAND were equipped/unequipped.
The table of average values are on the table below.

- O2 BAND equipped -> The average exhaust gas component values
CO : -19.74% NOX : -70.41% SO2 : -22.78%
- O2 BAND unequipped -> The average exhaust gas component values.
CO : +17.31% NOX : +71.43% SO2 : +51.44

3. Exhaust measurement

- Tester measured exhaust gas composition of value change depending on O2 BAND were equipped/unequipped.
- Exhaust values were measured at certified automobile inspection laboratory. (LUG-DOWN 3)

- Result that measured diesel vehicle without O2 BAND installed,
Mode 1 : 22%
Mode 2 : 13%
Mode 3 : 10%

- Result that measured diesel after O2 BAND installed,
Mode 1 : 15%
Mode 2 : 13%
Mode 3 : 3%
Total average
About 34% exhaust measurement was reduced.

4. Measurement of vibration value change

Tester measured vibration value change of engine, depending on O2 BAND were equipped/unequipped.

- The vibration value of the engine showed about 34% changing value.
- Although there were differences between each test because of environmental factors, we can check O2 BAND affects the vibration value of the engine.

A specific route was set in order to check how O2 BAND affects fuel efficiency.
*Fuel efficiency and CO2 emissions have same connection. Carbon dioxide has a 99.9% correlation with fuel efficiency. Vehicles with high fuel efficiency emit less carbon dioxide.

This test measures the component of the gas which the car emits in 2 minutes.
Tester measures the score in one cycle(4 times x 5 minutes).
Proceed by comparing the average value of every tested value.

Test measure 2 times out of 4 by installing O2 BAND and another 2 times by installing O2 BAND. This is to compare O2 BAND in most similar conditions.

MK-3000 cannot measure the exhaust gas level of diesel vehicles, the exhaust gas value of diesel vehicles was measured at an automobile inspection center located in pocheon, South Korea.

(Laboratory certified Automobile inspection method)

- Inspection method : Lug-Down3
- On the chassis dynamometer, the car’s accelerator pedal was set to maximum and selected mode 1, engine’s rated speed at 90% in mode 2 and 80% in mode 3 to measure exhaust density and engine output.

· As a result of measuring a diesel vehicle using the Lug- down3 without installed O2 BAND, mode 1: 22%, mode 2 13% and mode 3 10% was measured.
· After installing O2 BAND, average exhaust gas was decreased Mode 1: 15%, mode 2: 13 %, mode 3 %.

To measure the change in vibration value that occurs during the engine combustion due to measurement , a vibration meter was used depending whether or not the O2 BAND was installed.
