DN8340 4500kw high capacity and low speed marine diesel engine
DN8340 Introduction:
Model DN8340 diesel engine is direct injection,inline,turbocharged,intercooled,four stroke marine diesel engine,which adopts
equilibrium crankshaft structure,has the characteristics of reliable structure,stable running,lower fuel consumption and simple operation.
The engine block is of gantry box structure ,form an integrity with underslung crankshaft to reduce vibration.
The crankshaft is high quality steel alloy integral full grain die forging,designed with counterweight for each cylinder,manufactured with
complete machining technics,dynamic equilibrium inspection is taken to avoid crank unbalancing.
The connecting rod is die forging H section three piece structure to increase reliability and easy dismantling.The small end is of step design
to ensure adequate pressure bearing area.
The piston is of steel crown iron skirt assembly structure, improved steel crown design ensure better oscillating cooling efficiency and
effectively reduce crown working temperature.
The cylinder liner cooling adopts more effective cylinder liner inner cooling,it cools cylinder head via cooling body to meet cooling requirement.
The cylinder head is of intake and exhaust same level structure to increase cylinder head section rigidity.
The camshaft of one cylinder unit assembly structure,each unit can be remove to reduce its taken length.
Characteristics:
1. Meet with:ISO3046,ISO8178
2. Main application:ocean fishing vessels,tugboats/oil tankers,container ships,passenger and cargo ships,engineering vessels
3. Low fuel consumption,high capacity of loading,reliable running,convenient operation,HFO capability
Our advantages:
1. DN8340 series medium-speed large-power diesel engine is independently developed by AVESPEED in 2007,
it adopts underslung main bearing structure rather than traditional vertical main bearing structure and
features more compact structure, higher power to weight ratio and small vibration etc.
2. We have many cooperation experiences in diesel engine with the coastal countries,
3. They are confirmed to be very successful through our after-sales following with their excellent quality and technology.
