Expansion method for injector in internal combustion engine involves expanding injector after injector has been cooled

摘要

The internal combustion engine is heated at least partially in the area where the injector (1) is arranged. The injector is cooled and then expanded by a blow extractor (2). The injector is cooled by the introduction of coolant through an adapter (4) mounted on the injector. Bores (18,19) are diagonally formed on the adapter.
