The Calibration Technician – Solenoid Valve Timing (Mid-Level) is responsible for executing and supporting calibration activities for solenoid-actuated valve timing systems used in internal combustion engines or advanced valvetrain platforms. This includes fine-tuning system parameters, analyzing performance data, troubleshooting solenoid control behavior, and ensuring system performance under various operating conditions.
Perform setup, calibration, and validation of solenoid-controlled variable valve timing (VVT) systems on engine test beds, rigs, or component-level platforms.
Adjust control parameters such as cam phasing, actuation timing, lift profiles, and response delays using ECU calibration tools.
Interpret test data to evaluate timing accuracy, repeatability, current draw, and system stability across different speed/load points.
Troubleshoot solenoid actuation problems, including current faults, sluggish response, and control mismatches.
Work with calibration engineers to develop and refine maps for cold start, idle, part-load, and full-load valve timing strategies.
Maintain and validate calibration files, logs, and performance results as per project documentation and quality systems.
Support cross-functional development teams (design, simulation, controls) by sharing test results and performance feedback.
Ensure calibration tools, test setups, and instrumentation are maintained and calibrated as per schedule.
Calibration Execution:
Implement and adjust solenoid valve timing maps using calibration software like ETAS INCA, Vector CANape, or OEM-specific platforms.
Validate valve event timings under transient and steady-state conditions.
System Behavior Analysis:
Analyze trends in solenoid response time, current profiles, valve overlap, and timing drift.
Identify and isolate causes of inconsistent timing or actuation lag.
Test Rig & Engine Bench Operations:
Support setup, sensor calibration, and safety checks for test benches or engine dynamometers.
Ensure data accuracy by verifying sensor alignment and DAQ system reliability.
Documentation & Reporting:
Maintain up-to-date calibration sheets, test records, and daily activity logs.
Prepare summary reports and initial technical observations for engineering review.
Problem Solving & Support:
Conduct root cause analysis of system performance issues with solenoid actuators, wiring, or ECU mapping.
Recommend basic hardware or software modifications to improve timing consistency or reliability.
Diploma or Bachelor's degree in Mechanical / Automotive / Mechatronics Engineering or equivalent.
3–6 years of experience in engine or actuator calibration and testing (especially variable valve timing systems).
Proficient with calibration tools like ETAS INCA, CANape, or MotoTune.
Solid understanding of internal combustion engine timing systems, cam phasing mechanisms, and actuator dynamics.
Familiarity with solenoid control circuits, PWM/voltage control, and current diagnostics.
Strong analytical skills and experience with data acquisition and interpretation tools (e.g., Excel, MATLAB, LabVIEW).
Good communication skills and experience working in cross-functional development teams.
