Perkins InjectorAs one of the most complex parts of a diesel engine, the injector 131406500 or injector nozzle is required to withstand the temperatures and pressures inside the cylinder to produce an accurate dose of a fine fuel mist to ensure a thorough burn in the cylinder. With extremely small tolerances within injectors, 1 to 3 microns, and very high fuel pressures, issues can arise such as fuel contamination causing wear, or coking of external surfaces from an
