Abstract

Climate change is a critical worldwide concern, marked by increasing temperatures, severe weather phenomena, and substantial disturbances to ecosystems and human societies. More than 60% of vehicles are equipped with gasoline internal combustion engines. Consequently, minimizing harmful exhaust gas emissions such as carbon monoxide (CO), nitrogen oxides (NOx), and hydrocarbons (HC) is a crucial consideration in gasoline fuel combustion. A gasoline injector cleaner has been designed and implemented to simulate the real-time conditions for the injectors in the gasoline multiport injection system. This research examines the impact of injector cleaning on exhaust emissions and vehicle performance using chassis dynamometer tests involving five case study vehicles. The results indicate a significant improvement in vehicle brake power, ranging from a 3% to a 43% increase. Moreover, there is a significant reduction in harmful gases, especially CO gases, due to complete combustion inside the cylinder as a result of uniform spraying and atomization of fuel.
