COMBUSTION CHAMBER FOR DIESEL ENGINE AND STRUCTURE OF INJECTION NOZZLE

摘要

PROBLEM TO BE SOLVED: To supply fuel stably, suppress white smoke generated when starting an internal combustion engine, and improve combustion efficiency. SOLUTION: A fuel injection nozzle in which many main fuel injection holes 2 injecting fuel radially in a cylinder are formed and a glow plug 3 are arranged in a fuel injection hole in the fuel injection nozzle 1 in a diesel engine. The swirl of air-fuel mixture occurs in a combustion chamber, and an auxiliary fuel injection hole 4 for injecting a larger amount of fuel is formed on the upstream side in the direction of swirl when viewed from the glow plug 3 in the fuel injection nozzle 1.
