Dynamic measuring of performance parameters for vehicles engines

Paper deals with dynamic measurement of performance parameters for selected vehicles engines using incremental sensor attached to the rest bed roller. Data collection was performed with an eight-channel collector. The moment of the inertia is the result of the measurement, which can also be used in the measurement of performance parameters. The external speed characteristics of the engine primarily resulting from the dynamic measurement is the absolute result of the measurement. It can be concluded on the technical conditions of the motor vehicle based on the evaluation of external speed characteristics of the engine. It is possible to maintain consistently good technical state of the motor engine with an appropriate maintenance and contribute to the ecology and the economy of the vehicle operation.
