The intercooler of a turbocharged engine fails (stops cooling), while the boost pressure and the fuel–air ratio remain the same. Which statement correctly describes the effect? A Power falls, because the hotter charge is less dense, so a smaller mass of air (and fuel) enters per cycle; in an SI engine the tendency to knock also rises B Power rises, because the hotter air improves vaporisation and combustion of the fuel, and the risk of knock in an SI engine falls C Power is unchanged, because the boost pressure, and therefore the mass of air entering per cycle, is unchanged D Power falls only because the exhaust becomes cooler, so the turbine does less work; knock tendency is unaffected
