Opposed-Piston Engine

Basics

• A piston consisting of one or more cylinders each containing two opposed pistons wach, with combustion occuring in between them
• Thus these have no cylinder heads
• Thus these have less friction + heat waste/loss
• Simple Uniflow Two Stroke Pattern

Advantages

• These have no cylinder heads thus these have less friction + heat waste/loss
• Smaller Size
• Simpler Design
• High Efficiency

Disadvantages

• May need 2 Crankshafts and/or more gears
