1- What is “valve overlap” and how it's affect the performance of the engine

HW9 In an engine governor of the Porter type, the upper and lower arms are 300 mm and 350 mm respectively and pivoted on the axis of rotation. The mass of the central load is 17 kg, the mass of each ball is 3 kg and friction of the sleeve together with the resistance of the operating gear is equal to a load of 27 N at the sleeve. If the limiting inclinations of the upper arms to the vertical are 35° and 45°, find, taking friction into account, the range of speed of the governor and Sensitiveness of Governors.
