Cylinder head for internal combustion engine e.g. diesel engine, of motor vehicle, has coolant node with transverse channel extending from central channel up to peripheral channel to pass near place where spark plug is to be positioned

摘要

The head has a coolant node (20) with a central channel (26) surrounding a fuel injector (6), and a peripheral channel (24) surrounding inlet valves (4A, 4B), exhaust valves (5A, 5B) and a preheating spark plug (1). The core has a lower part (21) with a transverse channel (23) extending from the channel (26) up to the channel (24) to pass near a place where the plug is to be positioned.
