You really are going to need to be more specific. What kind of noise are you talking about? Are you asking why noises come out of the engine while operating normally? Are you talking about an irregular noise that you think could be a problem?
Engines make noise because there is a conversion of one energy to another and since a lot of it is wasted energy conversion we observe "waste energies" if you will. Such examples are heat and sound.
Inside a running engine there is a lot happening. Coolant and oil is constantly distributed throughout the engine and results in radiant heat and sound. Pistons are for ever going up and down, adding more sound. Combustion, which makes the pistons move, adds to the heat and sound. Parts that take this power of combustion and deliver it to the driving wheels are moving parts and add to heat and sound. Everything makes noise. Appreciated properly, all these wasted energies add to the beauty of the beast that is an internal combustion engine.
