The document discusses various auxiliary engine systems including carburetors, fuel injection systems, ignition systems, turbochargers, and emission control systems. It describes the different circuits in a Solex carburetor and lists the types of fuel injection systems for gasoline and diesel engines. The document also covers electronic ignition systems, variable geometry and waste gate turbochargers, exhaust gas recirculation, catalytic converters, and emission norms/reductions.
