F.O. PURIFIER
What is purifier and why we use it on board? As the name implies, Purifier purifies fuel oil used on board. It is a machine that separates impurities from fuel oil. Impurities can be both solid and liquid/water. Why there are impurities in fuel oil? Crude oil is refined in the refinery and produces various …
IGNITION QUALITY PARAMETERS OF SLOW SPEED DIESEL ENGINE
Ignition quality parameters: Energy Viscosity Maximum firing pressure. 4. Injection delay 5. Ignition delay . 1. Energy comparison • The injection pump is a volumetric pump • The higher the density the more energy it contains per volume unit • The density difference between HFO and MDO is larger than the difference in net calorific value …

DIESEL ENGINE CRANKCASE EXPLOSION
INTRODUCTION: For any fire to begin, the fire tringle needs to be completed. To complete a fire tringle there must be present of a combustible material, oxygen or air to support combustion and a source of heat in proportional ratio and within the flammable limits, the reaction which causes fire or explosion becomes cyclic. Image …
DIESEL ENGINE SCAVENGE FIRE
INTRODUCTION: For any fire to begin, the fire tringle needs to be completed. To complete a fire tringle there must be present a combustible material, oxygen or air to support combustion and a source of heat at a temperature high enough to start combustion. Source: www.marinediesels.info In the case of scavenge fires: the combustible …
LATEST DEVELOPMENT ON EU-MRV
Monitoring Reporting & Verification (MRV) is a standardised method to produce an accurate CO2 emissions inventory, through the quantification of CO2 emissions. The key principles of the scheme are to generate robust results using a lean approach considering parameters which are already monitored during normal operations. It is advocated as a way of monitoring a ship’s …
CYLINDER LUBRICATION SYSTEM
Cylinder lubrication in a low-speed main propulsion diesel engine: Cylinder lubrication For marine diesel engines operating on residual fuels containing sulphur, cylinder lubrication must generally serve the following purposes: ■ Create and maintain an oil film to prevent metal to metal contact between the cylinder liner and piston rings. ■ Neutralise sulphuric acid in order …
