Principles of measuring non-electrical quantities in engineering practice. The most commonly used non-electrical quantities sensors: Sensors of kinematic variables, force and pressure sensors, vibration measure-ment, measurement microphones, thermometers, etc. Non-Contact object digitalization and principles of non-contact 3D measurements. Experiments aimed at internal combustion engines and vehicles; evaluation of its operational parameters, particularly power, noise and emission parameters. Measurement of temperature, contact and noncontact methods, surface and fluids temperature measurement, heat transfer coefficient measure-ments, the measurement of rapid changes in temperature. Measurement of pressure and rapid changes in pressure. Measurement of fluid flow velocity: vane anemometer, hot-wire anemometer, CTA, the basics of optical methods.
