| INSTALLATION TESTS. CURVE 199F CYLINDER WATER LEVEL & AIRSPACE. (F'S & H/S ENGINES) TESTS. INSTALLATION TESTS:- TO DETERMINE THE STATIC WATER LEVEL & AIR SPACE IN THE F'S ENGINE FOR VARIOUS ANGLES OF INCLINATION, USING THE CRANKSHAFT CENTRE LINE AS THE HORIZONTAL DATUM & MEASURING THE WATER LEVEL UP THE VERTICAL CENTRE LINE OF THE ENGINE. Y-AXIS: GALLS AIR SPACE X-AXIS: INCH'S ABOVE CENTRE LINE OF CRANKSHAFT. MEASURED UP THE VERTICAL CENTRE LINE OF ENGINE. LEGEND: CURVE ① ENGINE LEVEL. α = 0° CURVE ② " TILTED (NOSE UP) 15° CURVE ③ " ( " ) 20° CRANKSHAFT CENTRE LINE T.A.GIBSON | ||
