Two-stroke Dual-Fuel engine program
18 November 201121 © Wärtsilä
Principles: • Engine operating accordingly
to Otto process
• Injection of gas at mid-stroke. Low pressure gas injection(<10 bar) sufficient
• High impact on NOX reduction
• Meets IMO Tier III without any after treatment
‘Pre-mixed lean-burn’ combustion
Scavenging Compression/ gas admission
Ignition expansion
HP pumpsHP evaporators
Expensive piping & installation ?
