Faqs
Frequently Asked Questions About Yanmar 6AY Marine Engine Spare PartsWhat is the Yanmar 6AY Marine Engine?
The Yanmar 6AY Marine Engine is a heavy-duty inline six-cylinder commercial marine diesel engine family designed for demanding propulsion applications.
The 6AY platform includes multiple engine configurations, such as:
- Yanmar 6AYM-WST
- Yanmar 6AYM-WET
- Yanmar 6AYM-WGT
- Yanmar 6AYAM-ET
The family uses direct fuel injection, turbocharging, intercooling, and robust mechanical construction for commercial marine service.
How Large Is the Yanmar 6AY Engine?
The Yanmar 6AY family has approximately 20.38 liters of displacement.
Typical 6AYM specifications include:
- Cylinders: 6
- Arrangement: Inline
- Bore: 155 mm
- Stroke: 180 mm
- Displacement: 20.379 L
Exact specifications depend on the complete engine model and rating.
Is the Yanmar 6AY a Four-Stroke Engine?
Yes.
The Yanmar 6AY operates on the four-stroke diesel cycle:
- Intake
- Compression
- Combustion and power
- Exhaust
A complete operating cycle takes place over two crankshaft revolutions.
Is the Yanmar 6AY Turbocharged?
Yes.
The Yanmar 6AY family uses turbocharging and intercooling.
The turbocharger increases the mass of air supplied to the engine, while the intercooler reduces the temperature of the compressed intake air before it enters the cylinders.
Available turbocharger components can include:
