Internal Combustion Engines Pick up the wrong statement about supercharging Supercharging at high altitudes is essential Supercharging results in fuel economy Supercharging reduces knocking in diesel engines There can be limited supercharging in petrol engines because of detonation Supercharging at high altitudes is essential Supercharging results in fuel economy Supercharging reduces knocking in diesel engines There can be limited supercharging in petrol engines because of detonation ANSWER DOWNLOAD EXAMIANS APP
Internal Combustion Engines The brake power (B.P.) of the engine is given by (where W = Brake load or dead load in newtons, l = Length of arm in meters, N = Speed of engine in r.p.m., S = Spring balance reading in newtons, D = Dia. of brake drum in meters, and d = Dia. of rope in meters) P = (Wl × 2πN)/60 watts P = [(W - S) π (D + d) N]/60 watts All of these P = [(W - S) πDN]/60 watts P = (Wl × 2πN)/60 watts P = [(W - S) π (D + d) N]/60 watts All of these P = [(W - S) πDN]/60 watts ANSWER DOWNLOAD EXAMIANS APP
