E15 Outboard Marine High Ethanol Fuel Endurance A study of the effects of running gasoline with 15% ethanol concentration in current production outboard four-stroke marine engines and conventional two-stroke outboard marine engines. Prepared By: David Hilbert

2 8/18/2015 Overview  Test Objective: Run 300 hours of wide-open throttle (WOT) endurance on 3 engine families. –Two engines from each family: One on E15 (15% ethanol blend fuel) and the other on pure gasoline. –9.9HP 4-stroke carbureted, –300HP Supercharged 4-stroke “Verado”, –200HP 2.5L 2-stroke EFI (represents “legacy” product)  Engine selection was reviewed and approved by NREL Technical Monitor –Test standards used were common qualification tests.  Test regimen was reviewed and approved by NREL Technical Monitor

3 8/18/ HP Carbureted 4-Stroke  More carbon deposits on piston underside and rods of E15 engine. E0 E15

4 8/18/ HP Carbureted 4-Stroke  The fuel pump gasket showed signs of deterioration on the E15 engine compared with the E0 (pure gasoline) engine. E15 E0  Material transfer from gasket to check valve in fuel pump.

5 8/18/ HP Supercharged 4-Stroke “Verado” Cylinder 3 Top Valve Cylinder 3 Bottom Valve Cylinder 6 Top Valve

6 8/18/ HP Supercharged 4-Stroke “Verado”  Carbon deposits may indicate that the E15 engine’s pistons and connecting rods were hotter during operation than those in the E0 engine. E15 E0

7 8/18/ HP EFI 2.5L 2-Stroke Recovered Pieces from Failed Rod Bearing Undamaged Rod Damaged Rod Undamaged Bearing

8 8/18/2015 Conclusions and Recommendations Summary  Despite the limited scope of the project several significant issues were discovered.  More testing is necessary to understand effects on: –Lubrication system in 2-stroke engines –“Driveability”- Examples: cold and hot start, acceleration, deceleration, etc.  Similar testing by Volvo Penta indicated difficulty starting the E15 engine. 1 –Storage (phase separation, corrosion, etc.) Source 1: M.
