automobile industry, there have been many outstanding achievements to serve mankind, but accompanied by the problem of environmental pollution, fuel depletion is also an important topic when industries develop In this project, our team focused on developing and building an engine model with control software recalibrated by ECU ATE Racing (change manufacturer's ECU parameters) to increase fuel economy From there, it is possible to evaluate and apply this in the future to save fuel for many other types of engines Key word: WAVE RSX FI, ECU ATE Racing, fuel economy, ii CONTENTS

the above calibration parameters, the engine will operate at no-load speed from 1000 - 1200 RPM, then the engine will start normally and will not shut down or the engine will run wild That will help the engine operate stably and save fuel The maximum engine speed will reach 6000 RPM because the engine is not pulling the load, so this rev speed will help the engine operate in the most fuel-efficient way possible 5.3.3 Sensor Voltage Parameter Sensor Voltage is the voltage parameter interface of the sensors in the actuator of the ECU In this interface there will be information of sensors such as AFR - Voltage Relation, ECT - Voltage Relation, IAT - Voltage Relation, MAP - Voltage Relation We can adjust the voltage of the sensors so that the motor operates according to the desired regulation 49 Figure 5.9: Calibrated ECT Voltage In this part, the group will adjust the voltage of the ECT sensor - Voltage Relation (Engine temperature sensor) for the purpose of "SAVE FUEL" as follows: - The engine temperature sensor generates a feedback signal to the ECU to know the current engine temperature But my team adjusted for the engine temperature from 560 – 700C to let the ECU understand that the engine is operating in Idle Speed Hot mode Thus, the motor will skip the Warm up step Because, during the warm up process of the engine, the engine speed when idling will work high to help the engine warm up This process will make the engine speed faster and consume a lot of fuel That's why my group intervened to calibrate the ECT–Voltage Relation sensor 5.3.4 Manufacture ECU information Figure 5.10: Basic information of engine Wave RSX FI As when our group first read all the information from the ECU engine of Wave RSX FI the information is as in the upper figure:  Idle Speed (Cold): 1500 RPM  Idle Speed (Hot): 1300 RPM  Maximum Speed: 7500 RPM 50 Figure 5.11: Default injection VE of engine Wave RSX FI From figure 5.10 we can clearly see that the injection time of injector is 0,3 s more than in the save fuel calibrate This mean that injector allowed to spray more fuel into the cylinder which will help increasing engine power Figure 5.12: Sensor voltage The voltage of ECT is as the default basic from manufacture This helps the engine go through warm-up process This process often takes a minute in real life 5.3.5 Calibrate increasing engine power First of all, increase the injection time of engine more than 0,3 mms when the Throttle is at 50% This helps the engine have a good start when a large amount of fuel pumped in to cylinder 51 Figure 5.13: Injector VE increase Figure 5.14: RPM increase After calibrate injector VE we move to idle and limit table In this table, we increase the maximum speed of the engine to 9000 RPM This action mean that we are setting up the ECU so that it will allow engine to run quicker than in the default setting without lack of fuel 52 Figure 5.15: TPS voltage calibrate In options, we increase the TPS voltage and max so that the throttle opens full even we not fully opened it This help to increase the engine power during riding 5.4 Measure parameters with messure oscilloscope 5.4.1 At 6000 RPM, fuel consumption a) At idle speed Figure 5.16: Injection time at idle speed in HanTek 53 Figure 5.17: Injection time at idle in ECU ATE At 6000 rpm, when in idle speed mode, the pulse measurement chart shows the highest voltage when the injector is operating is 4.86V and the lowest is -5.33V, and the time from the start of the injector until the shutdown The current supplied to the injector is 2.73ms, and the time from injector close to the next injector open is 108m/s Figure 5.18: Injection time at idle speed between cycle b) At 6000RPM 54 When the engine is operating at 6000RPM, the time from starting the injector until the current supply to the injector is cut off is 6.5m/s and the time from the injector close to the next injector opening is 12.5m/s Figure 5.19: Injection time at 6000RPM Figure 5.20: Injection time at 6000RPM between cycle When the engine speed has just reached the threshold of 6000 RPM, the engine will automatically cut off the fuel so that it does not exceed the threshold of 6000rpm, and this time is 90.9m/s, and when the throttle is opened larger, the fuel shutoff time of the ECU will the bigger 55 Figure 5.21: Injector cut-off time 5.4.2 Manufacture default setting (At 7500 RPM): Figure 5.22: Injection time at idle speed At 7500 rpm, when at idle speed mode, the injector opening time is 2.88m/s longer than at fuel-saving rpm This allows more fuel to be injected into the cylinder, making the engine more powerful Moreover, the time between injector close and open again is 77.6 m/s This is shorter than in 6000 RPM, this help for warm-up process and also for powering up the engine 56 Figure 5.23: Injection time at idle speed between cycle When the engine is operating at 7500 RPM, the time from starting the injector until the current supply to the injector is cut off is 5.18m/s and the time from the injector close to the next injector opening is 10.2 m/s Figure 5.24: Injection time at 7500RPM 57 Figure 5.25: Injection time at 7500RPM between cycle When the engine speed has just reached the threshold of 7500 RPM, the engine will automatically cut off the fuel so that it does not exceed the threshold of 7500 RPM, and this time is 77.2 m/s, and when the throttle is opened larger, the fuel shutoff time of the ECU will the bigger Figure 5.26: Injector cut-off time  Conclusion: After viewing the graphs, it can be seen that in idle mode and max engine speed, the fuel injection time will be different at manufacture default and fuel consumptions calibration when the injection time in manufacture default is much longer than in 6000 58 RPM And we can see after the adjustment the amount of fuel consumed by the engine will be significantly reduced 5.5 Calibrate result Default engine from manufacture Save fuel calibrate Increase power calibrate - Engines that are cold will need some time to warm up before running, - The engine skips the warming step - Engines that are cold will need some time to warm up before running - The amount of fuel at each injection stroke is higher than 0.3 mms - The amount of fuel in each injection stroke is less than 0.3 mms - The amount of fuel at each injection stroke is higher

content of the graduation project, on time and meeting the requirements and tasks set out -The model is completely designed according to the set goals -Contents of accompanying documents are compiled in detail for ease of use - Through the process of practicing and working with the group model, some other skills have been gained such as: teamwork skills, knowing how to use measuring tools, painting, welding -Through the implementation process, we have better understand the process of implementing a teaching model, not only full of technical content but also must achieve high aesthetic In addition, the implementation of the project also consolidates the knowledge learned and applies this knowledge in completing the model Therefore, we have achieved certain results that are meaningful in terms of science as well as practice The content of the topic is highly practical, students can practice on the model easily to stimulate the learner's ability to explore and be creative in learning The model is neatly designed with a reasonable layout of the integrated systems on the model However, during the research period, due to limited time and knowledge, it is inevitable that there will be shortcomings Our team is looking forward to your comments 6.2 Recommendations In general, the team has basically completed the project's objectives, in the process of working, the research team has approached new issues as well as possible development directions that can be applied to improve the quality of the project model and extend knowledge After implementing the topic, our group have some recommendations and suggestions to improve understanding and research on future such as: - Attach additional load to measure actual parameters when operating the machine Adjust other parameters such as ignition, TPS Adding more theoretical content so that students have an accurate understanding of the engine and simulate software thereby creating a premise for its research and development Currently, Ho Chi Minh City University of Technology and Education has been developed non-stop with the technology of the world, so we need to make more effort In order to continuously innovate, we need to update knowledge about the world technology every day and also practice on models to have a deeply understand those technology Moreover, university need to invest more in the development vehicle and teaching equipment, which can further train highly qualified human resources, helping the automotive industry to grow and achieve even greater achievements REFERENCES
