- Summary:
- Turbochargers play a crucial role in modern engines by increasing power output and fuel efficiency through intake air compression, thereby improving volumetric efficiency by allowing more air mass into the combustion chamber. However, this process also raises the intake air temperature, which can reduce charge density, lead to detonation, and create emissions challengessuch as smoke limits in diesel engines and knock in gasoline spark-ignited (GSL) engines. To mitigate this, intercoolers are used to cool the compressed air. Due to packaging constraints, intercoolers are typically long and boxy, limiting their effectiveness, especially at low vehicle speeds where ram air flow is minimal. This study investigates the use of auxiliary fans to enhance intercooler performance.Two methodologies were adopted: 1D simulation using GT-Suite and experimental testing on a vehicle under different fan configurationsno fan, single fan, and dual fans (positioned near the intercooler inlet and outlet). Results indicated that auxiliary fans significantly enhance heat transfer at low speeds, with dual fans offering the highest improvementup to 813% greater efficiency during hill climb conditions compared to no fan. At high speeds, benefits were negligible (<1%) due to sufficient natural airflow. These results support the application of intercooler fans for improved thermal management under low-speed, high-load conditions
