摘要：

Development of a sub-miniature, traversable, two-simultaneous velocity component fibre-optic, laser-Doppler velocimetry (LDV) probe for flow measurements in a production-car IC engine is discussed. The probe is manufactured to fit into an M8 spark-plug hole and it can be traversed 50 mm allowing measurements inside the engine cylinder including the spark-plug location. The probe has been first tested in a steady free round jet and next has been employed on a Honda CIVIC LX car engine for preliminary time-dependent velocity measurements at 10 mm and 36 mm into the engine cylinder. Results indicate lower turbulence intensity values closer to the spark plug than into the engine.
