Technical solutions for arctic engine
When 4-stroke diesel engines are operated in arctic environment, the very low ambient air temperature is a challenge. In engines, the ambient air is compressed and cooled before entering combustion chambers; water is used as cooling medium. With arctic air the cooling water can be thus cooled to levels not acceptable and risks arise for components supplied by same cooling water; overall heat balance is affected too. So water temperature must be restored at safe level: usually an electrical heater is installed outside engine. Scope of this work is to give a list of alternative technical solutions to assure efficient power output and safe engine operations in arctic environment. Involved thermodynamic systems have been investigated and technical improvements have been developed with continuous focus on performances and reliability. As conclusions it will be possible to notice, for all developed arctic arrangements, clear advantages as energy heat recovery, increased efficiency, optimized thermal performances and compact engine mounting.
