IC diesel engine especially large marine diesel with integrated cooling duct and starter air duct around join between cylinder sleeve and cylinder head

摘要

#CMT# #/CMT# A large diesel IC engine, e.g. for marine applications, has a cooling duct (23) around the top of the cylinder sleeve (22) and the adjacent part of the cylinder head to provide a cooling jacket as well as an air duct for starter air flow. No separate ducts are required, nor any costly castings. A coupling element (27) is fitted to each cylinder to connect to the ducts for inlet and outlet cooling water and for inlet starter air. #CMT#USE : #/CMT# Larger diesel engines, marine diesels #CMT#ADVANTAGE : #/CMT# A simplified cost effective design with improved cooling #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a vertical cross section through the top part of a cylinder for a large diesel engine. 21 : Cylinder head 22 : Cylinder sleeve 23 : Cooling chamber and starter air duct 27 : Connecting element to cooling and air ducts.
