28、stems for RIC engines. For governing systems based on other parameters (e.g. torque, temperature and load), the definitions given may be considered as a basis. ISO 2710-1 gives a classification of RIC engines and defines basic terms of such engines and their characteristics. NOTE The term Speed Gove
