- is crucial for maintaining a tight seal, preventing exhaust gas leakage, and ensuring efficient engine performance.

📍Maintaining a Tight Seal:
Over time, wear and tear can cause the valve seat and spindle to become uneven, leading to gaps and poor sealing.

📍Preventing Exhaust Gas Leakage:
A poor seal allows exhaust gases to escape, reducing engine efficiency and potentially leading to overheating and damage.

📍Ensuring Efficient Engine Performance:
A properly sealed valve ensures that the engine runs smoothly, with optimized compression, leading to better fuel economy and performance.

📍Addressing Wear and Tear:
Grinding helps restore the original shape and surface finish of the valve seat and spindle, creating a better seal.

⚠️Marine Diesel Engine Applications:
In large bore 2-stroke diesel engines, exhaust valve components operate under extreme thermal load and in a corrosive environment, making regular maintenance and grinding even more critical.

⚠️Specialized Tools and Expertise:
Grinding these components often requires specialized tools and expertise, so it's best left to professionals or companies specializing in marine diesel engine repair.

Techcross's Power Rectifier Unit (PRU), a core component of their Electro-Cleen™ System (ECS), is a crucial part of their ballast water management system, converting AC power to DC power for the electrolysis process that disinfects ballast water.

Function:
The PRU converts alternating current (AC) from the ship's power supply to direct current (DC), which is then used to power the Electro Chamber Unit (ECU) where electrolysis takes place.

Electrolysis:
The ECS uses electrolysis to disinfect ballast water by producing hypochlorite in situ, which destroys the cell membranes of microorganisms and prevents regrowth.

Cooling:
To maintain the quality of the PRU, the cooling water temperature must be consistently maintained.

Safety:
The system monitors temperature and pressure of the ECS, shutting down if they exceed reference values to prevent safety issues.

Key Components:

Electro Chamber Unit (ECU): The heart of the system where electrolysis occurs.

Electrodes: Techcross uses proprietary electrodes with special coatings to optimize electrolysis.

Sensors: The system uses various sensors, including flow meters, temperature sensors, and gas detection sensors to monitor the system's performance and safety.

PURIFIERS FRICTION CLUTCH

In a purifier, the friction clutch's purpose is to protect the electric motor from overload and damage during startup, allowing the motor to gradually engage with the heavy purifier assembly as it reaches a certain speed.

Here's a more detailed explanation:

Heavy Load:
The purifier's bowl assembly is very heavy, and directly connecting it to the motor for immediate rotation would cause an excessive starting current and potential overheating or burnout of the motor.

Gradual Engagement:
The friction clutch, with its pads or drum assembly, is designed to engage gradually with the bowl as the motor starts and gains speed.

Centrifugal Force:
As the motor rotates, centrifugal force pushes the clutch pads outwards, causing them to engage with the drum and gradually transfer the rotational motion to the bowl.

Protection:
This gradual engagement prevents the motor from being subjected to a sudden, heavy load, protecting it from damage.

Safety Mechanism:
In case of unexpected or sudden loads on the centrifuge due to malfunction, the friction clutch prevents the load from reaching the motor, acting as a safety mechanism.

GE FUEL INJECTION VALVE

Fuel Injection valve functions by precisely injecting a measured amount of pressurized fuel into the engine cylinder at the correct timing, allowing for efficient combustion by atomizing the fuel into a fine mist and mixing it with air within the cylinder, ultimately generating power by igniting the mixture.

📍Key aspects of the fuel oil injection valve function:

Atomization:
The primary function is to break the fuel into tiny droplets for optimal mixing with air, ensuring complete combustion.

The valve opens and closes at precisely calculated moments during the engine cycle to achieve optimal combustion.

📍Components of a fuel injection valve:

Valve body: Houses the internal components and provides a connection to the fuel line.

Nozzle needle: A needle-like component that opens and closes to control fuel flow.

Spring: A spring mechanism that pushes the nozzle needle back to its closed position when not actuated.

📍Important factors affecting injection valve performance:

Fuel quality: The quality of the fuel can impact the atomization and combustion process.

Injection pressure: Higher injection pressure typically leads to better atomization.

Nozzle design: The design of the nozzle holes influences the spray pattern and fuel distribution within the cylinder.

⚠️Note: Fuel injectors may vary from sizes,construction, design and mechanism depending on the Maker but the operating principle is basically the same.

L**E OIL CENTRIFUGAL FILTER

A l**e oil centrifugal filter uses centrifugal force to separate contaminants from lubricating oil. This helps to improve engine performance and extend oil change intervals.

How it works?
Dirty oil is fed into the centrifuge bowl.
The bowl spins rapidly, creating centrifugal force.
Heavier contaminants are forced to the outside of the bowl and collected on a removable paper insert. Clean oil moves to the center of the bowl and is expelled through nozzles.

Benefits Extended engine life, Increased oil change intervals, Reduced operating and maintenance costs, Improved machine reliability, and Positive environmental impact.

Installation

Centrifugal oil filters are often installed on the engine side cover, near the front-end box. They are designed to be easy to clean and service.

Troubleshooting

If the centrifugal filter builds up deposits, it may indicate that the external separator unit is not working properly.

/ME EXHAUST VALVE OVERHAULING/

A main engine exhaust valve's primary function is to allow the burnt gases produced during combustion in the cylinder of a large engine to escape, effectively releasing the spent exhaust gases out of the engine after the power stroke, enabling the cycle to begin again with a fresh air-fuel mixture; essentially, it acts as a controlled release valve for the exhaust gases.

Key points about the exhaust valve:
Location:

Situated in the cylinder head of the engine.

Operation:
Opens at the right time during the combustion cycle, allowing the exhaust gases to flow out into the exhaust manifold.

Closing mechanism:
A valve spring (spring air) typically forces the exhaust valve to close after it opens, ensuring a proper seal within the cylinder.

Controlled by camshaft:
The timing of the exhaust valve opening and closing is regulated by a camshaft that interacts with the valve stem
(as for the conventional engines).

Electronically controlled Engines however operates via signal given by the CAS and actuated by FIVA( ME Engines B&W); and by VCU ( Wartsila)

A fuel purifier works by using centrifugal force to separate water and other contaminants from fuel, utilizing the difference in density between the fuel and impurities; as the fuel spins rapidly within the purifier, heavier particles like water are forced outwards to the edges of the bowl, while the cleaner fuel remains in the center and is then collected for use.

Key points about fuel purifiers:

Centrifugal force:
The primary mechanism behind fuel purification is the high-speed rotation of a bowl within the purifier, creating centrifugal force that separates heavier contaminants from the lighter fuel.

Density difference:
The separation process relies on the fact that water and other impurities are denser than the fuel, causing them to move outwards when spun.

Bowl design:
The purifier bowl has a series of discs or baffles that further enhance the separation process by increasing the surface area for contaminant collection.

GE Turbocharger Overhauling

Maker: ABB Turbosystems Ltd.
Model:TPS 52
Generator Engine: 6EY22 AWL

A turbocharger, also known as a turbo, uses exhaust gas to spin a turbine that compresses air and increases engine power.

How it works?
1. Exhaust gas spins the turbine wheel
2.The turbine wheel spins the compressor wheel through a shaft
3.The compressor wheel sucks in air and compresses it
4.The compressor housing converts the air into a high-pressure stream
5.The compressed air is pushed into the engine
6.The engine burns more fuel to produce more power
