The diesel engine is one of the most efficient combustion engines. For the highly stressed components of common rail injection, the Hirschvogel Group supplies important parts such as injector bodies, rails as well as camshafts and cylinder heads for high-pressure diesel pumps. 

In order to improve engine efficiency and meet statutory emission requirements, increasingly higher pressures are also being used for gasoline direct injection. To this end, cast and brazed applications are being successively replaced by pressure-tight forgings.
