- They allow some items to be surveyed in rotation curve of anual cycle (20%) .Then survey will over by 5 years . So it is called CSM.
- Class will allow C\E to survey that class surveyor to credit the survey at anual levels
The electrohydraulic control mechanisms of the ME engine replace the following components of the conventional MC engine: Chain drive for camshaft Camshaft with fuel cams, exhaust cams and indicator cams Fuel pump actuating gear, including roller guides and reversing mechanism Conventional fuel pressure booster and VIT system Exhaust valve actuating gear and roller guides Engine driven starting air distributor Electronic governor with actuator Regulating shaft Engine side control console Mechanical cylinder lubricators.
