SPECIFICATION OF THE ENGINE
Fuel Oil System
The Wartsila Vasa 32 engine is designed for continuous operation on heavy fuel oil (HFO) as well as light fuel oil (LFO).A preheated engine can be started directly on HFO provided that the external fuel system has the correct temperature and pressure.The engine can also be stopped on HFO although the external system has to stay in operation i.e.fuel must be circulated through the stopped engine continuously for heating purposes.
The internal fuel system comprises the following equipment:
- Low pressure pipes make of steel
- High pressure pipes,double wall with common leak alarm
- Injection pumps,individual for each cylinder
- Fuel injector in each cylinder
Lubricating Oil System
The lubricating oil system is lubricating the bearings and the cylinder liners in the engine.Furthermore,the lube oil is also cooling the piston tops.The Wartsila Vasa 32 engines have a wet sump oil system.
The internal lubricating oil system comprises the following equipment:
- Pipes made of steel
- Oil sump of wet type
- Engine driven main lube oil pump with pressure regulating valve
- Two by-pass centrifugal filter
- Start up / running in filters
- Non-return valves in oil supply pipes
Starting Air System
All Wartsila Vasa 32 engines are started by means of compressed air with a nominal pressure of 30 bars.The start is performed by direct injection of air into the cylinders through the starting air valves in the cylinder heads.The V-engines are provided with starting air valves for cylinders in the A-bank only.The master starting air valve can be operated both manually and electrically.
The compressed air system for operation of the starting fuel limier and the electropneumatic overspeed trip have their own connections to the external starting air system.
The internal starting air system comprised the following equipment:
- Pipes made of steel
- Starting air master valve
- Valve for electropneumatic overspeed trip
- Solenoid valve for fuel limiter
- Start blocking valve to prevent starting when turning gear is engaged
- Starting air distributor
- Starting air valves in each cylinder head (only A-bank cylinders in V-engines)
- Fuel limiter
- Air container for emergency stop system
- Pneumatic stop cylinder at each injection pump
- Booster for speed governor
- Flame arrestors
- Air filter for control air

引擎规格
燃油系统
瓦锡兰32 发动机被设计成除轻质燃油（汽油）以外的重质燃油（柴油）运行的发动机.且当外部燃油系统供给的柴油达到要求的温度及压力时,预热发动机就可以被启动.虽然外部系统仍工作,发动机也可以被停止.为了达到加热的目的,油必须不断的被循环通过停止的发动机.
内部燃油系统包括以下设备：
- 钢制低压力管
- 有一般泄漏报警的双壁高压管
- 针对汽缸的独立注射泵
- 每个汽缸中的喷油嘴
润滑油系统
润滑油系统是在发动机中润滑轴承和缸套的体统.此外,润滑油也冷却活塞台面.该瓦锡兰vasa 32发动机有一个湿式油底壳的油系统.
内部润滑油系统包括以下设备：
- 钢制管
- 湿式油低壳
- 由发动机驱动的有压力调节阀的主润滑油泵
- 双通离心式过滤器
- 启动/运行中的过滤器
- 油供应管道中的非回流阀门

启动空气系统
所有的瓦锡兰vasa32发动机,都借助30大气压的压缩启动空气.这个启动,是由直接注射空气进入气缸,通过在气缸正面的启动空气阀完成的.在气缸中,V型发动机被提供了启动空气阀.主启动气门可以手动或电动的方式启动.
用以运行启动燃料的压缩空气系统,有其自有的与外部启动空气系统的连接点.
内部启动空气系统包含以下设备：
- 钢制管
- 空气启动阀
- 电气动超速脱扣阀门
- 电磁阀燃油限制器
- 启动阻止阀,以保护旋转轴卡死的启动
- 起运空气分配器
- 启动空气阀在每个缸盖顶(只有V型发动机 A-bank 汽缸才有)
- 燃油限制器
- 为紧急停止系统做的空气箱
- 每个注射泵里的启动停止汽缸
- 助推调速器
- 阻火器
- 控制空气的空气过滤器
