COMPARISON OF CYL. LUBRICATING SYSTEM
| Description | Mechanical Type | Alpha Lubricator |
| Feed Rate |
0.9 g/bhp.h (K/L) 1.1 g/bhp.h (S) |
S % x 0.25 g/bhph (Standard :0.8 g/bhp) |
| Oil Consumption | RPM dependent | LOAD dependent |
| Adjustment of Feed Rate | Pump Stroke (Adjusting Bolt) | Injection Frequency (in HMI) |
| Stroke | Adjustable | Fixed |
| Injection Frequency | 1 / 1 revolution ( fixed ) | Adjustable (1 / 4 revolution ) |
| Injection Pressure | 3 – 5 bar | 25 – 30 bar |
| Oil Actuating Power | Camshaft Rotation | Booster Oil Pressure |
| Operating Method | Mechanic | Electronic |
LUBRICATION PRINCIPLE
- Intermittent lubrication where an engine cycle with lube oil injection is followed by one or more (normally 4) cycles without oil injection
- The injection is timed in relation to the position of the piston ring
- The specific feed rate is controlled by variation of the injection frequency. (solenoid valve on-off interval)
- Adjusting of the feed rate in relation to MEP, LCD and POWER
- Pre-lubrication of the cylinder can be done just before start of the engine. (12 time Continue)
- Reduction of the Emission level
- Element for Intelligent Engine Concept
BWTS SYSTEM
HHI has developed a ballast water Treatment system for ships, Eco & HiBallast, which will protect marine environment from the transfer of foreign organisms via ballast water
