WORK EXPERIENCE

10/15 – 02/2017 ECOMOTORS. Senior Technology Engineer - Stress Analysis of Opposed Piston Engines: Thermal and Mechanical analysis performed on engine components. Modelled the whole engines to study the stresses and deformations when subjected to thermal and mechanical loads. Also assessed them for fatigue.

01/89 – 06/2015 DAIMLER DETROIT, Detroit, Michigan. Senior Technology Engineer - Stress Analysis and design of Diesel Engines Components: Several Cylinder head joints, Gaskets, Cylinder Kits, Injector components (Body, Solenoid valves, Spring cage, Spray tips), Exhaust Manifolds, Flywheel housings, Engine mounts, Crankshafts, connecting rods, Pistons, and salable Projects including NASA, ARMY, NAVY and DOE (Department of Energy)

1.Cylinder Head Joints: Several Cylinder Head joint, 3-decks and 2-decks designs, individual, and slab heads were extensively analyzed; some of them are:

a.Low Heat Rejection M109 Abraham cylinder head with 5 proprietary insulation material analyzed. Recommended design changes which enabled the engine pass the NATO test requirement.

b.Detroit Diesel 11.1 and 12.7 Liters Cylinder head joint. Analyzed and recommended modifications of the coolant jackets, injector areas, and increased the bolt column which resulted in robust cylinder head and reduced warranty cost for the company. The engine was number 1 in North America for six straight years and lasted over 20 years.

c.Creep analysis performed on existing cylinder head after a major customer operating mines in Morocco and China complained of high altitudes related failures. The cylinder head was modified to meet this customer’s request and the head failures were resolved.

d.Traveled to Aachen, Germany to work with FEV on VM-Motori 2.5-liter aluminum cylinder head for the Chrysler Jeep; Design changes were recommended to resolve the head failures; the head passed the 350 hrs test cycles requirement.

e.High Power Density (HPD) cylinder head funded by the Department of Energy (DOE) and Navy for the Military; Heat rejection through the Fire-deck, Exhaust ports, Cylinder liners and Piston Crown were correlated to the measurement. The results helped in the improvement of Detroit Diesel engine.

f.Design recommendations on Detroit Diesel 20v149 Cylinder head and block specially built for the Military to power their ship accessories; I was commended by the Captain of the Ship when he paid a courtesy visit to Detroit.

g.Analyzed two new 6.8Liters and 3.2 Liters engines, Nevada and Delta, respectively, that were geared for Asia region markets.

2.Gaskets: Analyzed all various kinds of heavy duties gaskets; studied them extensively for their sealing abilities; Cylinder head joints, Exhaust Manifolds, Flywheel Housings-Crankcase joints, etc.

3.Cylinder Kit: Piston, Piston Rings, cylinder liner, Pin, Bearings, and Connecting rods assembly for several engines were extensively analyzed. Calculated the heat rejection through the piston crown and used their values to determine oil needed to cool the cocktail shaker of the piston. Optimized the Cylinder liner grooves to minimize liner temperatures and thereby prevent Piston ring scuffing and Blow-bye of gases at the fire-ring reversal.

4.Injector Components: Analyzed several Spray tips (Low sac and Valve Closed Orifice); effects of number of spray holes, hole diameters and spray angles on their durability. Used both Finite Element Analysis (FEA) and Boundary Element Analysis (BEA) programs to analyze intersecting holes for stress concentration. A major success that saved the company from high warranty cost was the use of SPATE to detect the unevenness of needle seat resulting from manufacturing which FEA could not detect.

5.Exhaust Manifolds: Have analyzed several Exhaust Manifolds for both normal and elevated altitudes operations. Recommended changes that enable the exhaust manifold passed the 2,000 hours’ requirement on durability stand. Calculated fatigue safeties on them using both Stress and Strain Life methods. Also performed creep analysis.

6.Flywheel housings and Engine Mounts analyses: Evaluated Flywheel housing and both front and rear engine mounts for vertical, lateral and axial shock loads to as high as 9g; design changes recommended to obtain robust designs.

7.Crankshafts: Evaluated several small and large engines crankshafts;

a.Calculated and generate Polar Moment charts for Crankshafts External loads applications (still used on DDC engines, both on Production and discontinued engines).

b.Analyzed a 20-V Cylinder Engine Crankshaft, a combination of two 6-V and 8-V engines specially built for the military; the firing orders, crank pin and journal geometries, counter-weights, cylinder kits mass and inertias, speed, and material strengths, Goodman fatigue safety factors were used in their evaluations.

c.Flywheel-crankshaft Joint Assurance of all Detroit Diesel Corporation (DDC) engines; i.e. the ratios of the calculated maximum, minimum and nominal engine friction torque capacities were used to classify the robustness of 14 Detroit Diesel engines. The study enable DDC identified the weak and strong engines among her fleet.

8.Connecting Rods: analyzed and qualified Rods for increased injection pressure loads, especially when the engines ratings were upgraded. Have analyzed several connecting rods for both push and pull loads and calculated their fatigue safeties.

9.Pistons: Several Cross-head Pistons, including thermal coated Pistons were analyzed; also analyzed and recommended design changes on the Turbo-Rotor-Compounding opposed piston engines contracted to DDC by the military for evaluation and advice.

10.NASA Saleable Program: Silicon Nitrite Valve of the NASA Adiabatic engine contracted to Detroit Diesel Allison (Old DDC name)

11.Strong Knowledge in Material Non-linear behavior of Gray Cast Iron, which I have used on many components.

12.Analyzed several other engine components.
