Bob Straub is a very pragmatic problem solver, using experience and judgement as well as and many learned techniques and tools problem solving such as Kepner Tregoe, Shainin, Red-X, DOE, and a variety of statistical approaches.

Examples of Problems Bob  has worked on include:

• Product variability
• Fuel system plunger seizure and or sticking
• Fuel system structural failure/cracking due to both manufacturing and design issues.
• Warranty “Trouble Not Found” issues
• Low fuel lubricity wear issues
• High pressure valve seat erosion and wear
• Common rail injector over-fueling  (steady and intermittent)
• Injector output drift
• High pressure seal failure
• Fretting erosion issues
• Check valve design issues
• Ceramic Ball Failure
• Low pressure seal failures
• O-ring failures
• Cavitation erosion
• Camshaft and follower design
• Fuel line fractures and sealing
• Fuel filter issues (plugging, waxing, particle trapping efficiency, water separation)
• DEF Injector issues
• Exhaust fuel injector issues (HC injection for DPF Regeneration)
• Engine bearing failures
• Engine smoke and performance issues
• Engine cold start issues
• Injector train wear issues
• Engineering organizational issues
