Design and Experiment of a Prototype Electronic Control Unit Direct Injection Fuel System Arduino-Based for 2-stroke Spark Ignition Engine

Abstract

The development of technology on the 2-stroke direct-injection spark-ignition engine is expected to be a solution to optimize engine performance and reduce exhaust pollution. The fuel injection system in the operation of the spark-ignition engine is controlled by the Electronic Control Unit (ECU), so this study aims to design and experiment with a prototype of an Arduino-based direct injection fuel injection electronic control unit for 2-stroke spark-ignition engines. This research method begins with the design of an electronic control unit prototype that is selected for easy setup and low cost. Then, experiments were conducted on variations in injection timing and injection duration, which are the two main parameters of the fuel system to determine their effect on engine performance. This data is then used as a basis for setting the amount of fuel injected. The results show that there is an optimal performance under certain conditions from setting the injection timing and injection duration which is easily applied to the open-source code setting of this electronic control unit.

Performance and Emission Characteristics Using Dual Injection System of Gasoline and Ethanol

“…Exhaust gas emissions from the combustion of motor vehicles in the form of carbon dioxide (CO₂), carbon monoxide (CO), nitrogen oxides (NOx), unburned hydrocarbons, and metallic elements such as lead (Pb) are a serious concern because of the impact on the performance of these gases which can reduce levels of health and safety of human life [19]- [22]. Therefore, modifications to old technology are also made to improve the effect of technology on the environment [23].…”

Arduino uno-based electronic control unit module remapping to achieve optimal engine rotation speed on spark ignition 2-stroke direct injection engine

“…Research using Arduino Uno controls applied to 2-stroke engines with direct injection simplifies the process of re-mapping the program for injection time and duration and has succeeded in increasing performance [14] in research [14], the injection time angle is too far, and the amount of fuel injected is set constantly. It is felt that the accuracy of the results obtained is lacking.…”
