In order to initiate combustion, a reciprocating engine starter rotates the engine at the necessary speed. Once the engine is started, the starter disengages. For this discussion, please complete the following: Identify the different types of electric starters used in reciprocating engines. Research and explain how the three-unit electromagnetic generator operates. Discuss the purpose of a current limiter, a voltage regulator, and reserve current relays used in generator control. Explain the limitations of the generator and identify any ways to improve and/or protect the system. with references
