Internal Combustion Engines The knocking tendency in spark ignition engines may be decreased by Controlling the air-fuel mixture Controlling the exhaust temperature Controlling the ignition timing Reducing the compression ratio Controlling the air-fuel mixture Controlling the exhaust temperature Controlling the ignition timing Reducing the compression ratio 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) 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 P = (Wl × 2πN)/60 watts P = [(W - S) π (D + d) N]/60 watts ANSWER DOWNLOAD EXAMIANS APP
