Determinação do trabalho O trabalho determina-se durante o ciclo de ensaio multiplicando de forma síncrona os valores da velocidade e do binário ao freio para calcular os valores instantâneos da potência ao freio. A potência do motor ao freio deve ser integrada durante o ciclo de ensaio para determinar o trabalho total (ver também o ponto 6.3.5). 7.3. Verificação e calibração
