An intake/exhaust system and a method of controlling intake air temperature and pressure for a dual-mode homogeneous charge compression ignition (HCCI) engine is provided. The system may include an air compressor including at least two output air flow paths, an intercooler for cooling air from one of the air flow paths, and heat exchangers for heating air from another one of the air flow paths. Control valves may be provided for controlling the mass ratio of air through the air flow paths to thereby control temperature and pressure of air supplied to the engine. The first air flow path may direct air to the engine via the intercooler and the second air flow path may direct air to the engine via the heat exchangers, whereby, air at first and second controlled temperatures and pressures may be supplied to the engine for operation in SI and HCCI modes.

Then an optical injection device optically injects the modulated optical signal into the second light source, and the predetermined specific two optical signals of the modulated optical signal are injection-locked into the predetermined two further optical signals of the multi-mode optical signal, so that the second light source generates an injection-locked predetermined specific two optical signals.
