The Volvo TAMD63L/P is a in-line 6 cylinder four stroke direct injected turbocharged diesel engine with after cooler
Bore: 3.87 in.
Stroke: 4.7 in
Displacement: 333 cu inches (5.46L)
Compression ratio: 15:1
Dry weight incl ZF 220A gear box: 1836 lbs.
The TAMD63 is a powerful, reliable and economical marine diesel engine, specially developed for fast planing and semi-planing craft. The installation volume is approx 30% less than that of the preceding engines.
The engine has been specifically constructed for efficient turbocharging with a high power/ fuel consumption ratio. Thus offering excellent fuel economy.
Durability and low noise levels
The Volvo Penta in-line six is a well balanced unit with smooth and vibration free operation and low noise levels. The torsionally-rigid cylinder block and crank mechanism are designed to withstand many hours of demanding operation.
To maintain a stable working temperature in cylinders and combustion chambers, the engine is equipped with piston cooling and freshwater-cooled oil cooler.
The engine is also fitted with replaceable cylinder liners and valve seats/ guides to ensure maximum durability and service life.
Low exhaust emission levels
A low-air rotation combustion technique, producing optimum airflow, and a high pressure injection system with 5-hole injectors ensure an optimum fuel-air mixture. This greatly contributes to reduced noxious exhaust emission levels. The direct injection (DI) system ensures a low fuel consumption. The engines are certified according to SAV, IMO and IMO US/EPA.
The two-pole electrical system is specially adapted to demanding marine environments with remote and flex-mounted senders as well as moisture-proof connectors.
Ease of service and maintenance
The single poly-V drive belt driving the alternator and freshwater circulation pump (a single service point at the front of the engine) together with the oil filter and the by pass filter contribute to ease of service and maintenance.
