- Summary:
- Passenger vehicle users often manoeuvre their cars in diverse and unpredictable driving patterns. The vast and varied terrain of the Indian subcontinent further complicates this scenario, introducing unique challenges due to differences in driving expertise, vehicle usage, and environmental conditions. A specific challenge addressed in this paper arises during different engine temperatures and transient driving conditionsa critical phase for engine calibration to ensure optimal drivability and emissions performance.With current calibration practices, a backfire like abnormal engine noise was observed during certain transient driving patterns. This paper presents a novel calibration methodology designed to eliminate such abnormal noise. The proposed approach involves a step-by-step transient calibration refinement, making the calibration process more robust and adaptable to any driving behaviour.The paper outlines the specific challenges encountered and details the multi-level calibration and validation strategy used to resolve the issue, thereby enhancing overall vehicle drivability performance and customer satisfaction
