Sebagian Rumus mesin 4T Wong engineering mesti yo ngerti.....qiqiqiiqi Power BHP = PLAN/33,000 P is brake mean effective pressure, in PSI L is piston stroke, in feet A is the area of one piston, in square inches N is the number of power strokes per minute Piston Speed Cm = .166 x L x N Cm is mean piston speed, in feet per minute L is stroke, in inches N is crankshaft speed, in RPM Brake Mean Effective Pressure (BMEP) 2-Stroke BMEP = (HP x 6500)/(L x RPM) 4-Stroke BMEP = (HP x 13000)/(L x RPM) L = Displacement in Liters i.e., 80 cc = .08 Liters 1 ci. = 16.39 cc Piston Acceleration Gmax = ((N^2 x L)/2189) x (1 1/(2A)) Gmax is maximum piston acceleration, in feet per second squared N is crankshaft speed, in RPM L is stroke, in inches A is the ratio of connecting rod length, between centers, to stroke.
