Abstract:  
ZERO Products Div., Clemco Industries Corp. 2000 Clemco Industries Corp. Reprinted with permission An automotive OEM supplier for a diesel engine manufacturer asked ZERO to help make their fuel injector nozzles more durable. These injectors shoot a mist of fuel directly into the motor's combustion chamber. The automated system that installs the injector into the engines applies a side load that can crack or break off the tip of the nozzle. If a nozzle fractures, it can destroy the engine, some of which are valued at tens of thousands of dollars.
