Injection Nozzles
Each engine cylinder combustion chamber is equipped with 1 injection nozzle. The injection nozzle has a single fuel inlet fitting and 2 fuel return fittings (1 on each side of fuel inlet fitting). The nozzle is threaded into the cylinder head. Injection nozzles are spring loaded and calibrated to open at a specified fuel line pressure. The combustion chamber end of the nozzle has a replaceable compression seal and carbon stop seal.
