    The nozzle-and-holder assembly is required for injection of fuel into the diesel engine's combustion chamber. It has a major influence on mixture formation and combustion and therefore contributes to optimization of engine power as well as exhaust gas and noise development. Bosch offers various types of nozzle-and-holder assembly that are suitable for all conventional systems and engine types – from single-cylinder engines to car and truck engines.
