Análisis de la tasa de inyección bajo el efecto de un potenciador de respuesta del acelerador en un sistema de inyección Tipo GDI

Abstract

The accelerator pedal, traditionally controlled mechanically via a cable, has evolved into an electronically operated component. This shift has led to the development of various devices designed to interface with it, such as the accelerator response booster. This device modifies the signal generated by the pedal's sensor, altering engine behavior. This study investigates the impact of the accelerator response booster on the GDI (Gasoline Direct Injection) system. Sensor and actuator data from the GDI system were collected under two operating conditions: with and without the booster. Additionally, emissions tests were conducted in compliance with INEN 2204 regulations, which mandate evaluations at idle and 2500 RPM. The findings reveal that the response booster significantly affects the injection pulse, with a 23% reduction at idle and a 50% reduction at 2500 RPM compared to standard operation. Corresponding variations in pollutant gas emissions were also noted. While the booster improves throttle responsiveness by decreasing the injection pulse, it concurrently increases pollutant emissions, highlighting a trade-off between enhanced performance and environmental impact.
