What is MC main engine?
This engine type uses a mechanically driven camshaft for fuel injection, cylinder lubrication, and to control the timing of the starting air and exhaust. Above all the L35MC engine has won the top share in the world market and should rightly be called the world standard for small bore.
What is the meaning of B&W engine?
Burmeister & Wain
This chapter discusses low speed diesel engine technology from Maschinenfabriek Augsburg-Nurnberg (MAN) Burmeister & Wain (B&W). The company introduced electronically-controlled ME versions of the 500 mm to 1080 mm bore models in 2001 to offer the same outputs as their MC engine equivalents.
What is the meaning of Me engine?
This engine electronically controls fuel injection, cylinder lubrication, and the timing on elements such as the exhaust. The “ME Type Engine” was developed in response to the demands of this new era, and has been in production at Makita Corporation since 2013. …
How does ship engine work?
Marine engines on ships are responsible for propulsion of the vessel from one port to another. The engines used onboard ships are internal combustion engines (a type), in which, the combustion of fuel takes place inside the engine cylinder and the heat is generated post the combustion process. …
What is super long stroke engine?
Super long stroke means increased swept volume allowing more mass of air to be drawn into the cylinder which in turn allows more fuel to be burnt, hence increasing power output. Super long stroke increases piston travel time and thereby decreases crank speed so more time for combustion during the stroke.
What is ultra long stroke engine?
A slow-speed, two-stroke engine which uses a large stroke to bore ratio to utilize the improved thermodynamic efficiency resulting from the uniflow scavenging. It also uses a lower shaft speed to improve the propeller efficiency.
What is the difference between me B and Me C engines?
The ME-B has been designed as a cost-effective version of the earlier ME-C engine developed by MAN Diesel & Turbo in 2003. While the ME-C features electronic control on both fuel injection and the exhaust valve drive, the ME-B boasts an electronic controller dedicated solely to fuel injection.
What is PMI in main engine?
The conversion of energy inside an engine’s combustion chamber is the diesel engine’s most essential process in terms of power and efficiency. PMI VIT for MC engines automatically optimizes and monitors the maximum combustion pressures inside the chamber. …
What are the 3 main engine systems?
Main Engine Systems
- Lubricating Oil System.
- Main Bearing Oil System.
- Crosshead Bearing Oil System.
- Cylinder Lubrication System.
- Cooling Water System.
- Cooling Water System Description.
- Fuel Oil System.
- Circulation System.
Why do ships use 2 stroke diesel engines?
Both 2 stroke and 4 stroke engines are widely available in the market but for a large ocean-going merchant vessel, a 2 stroke engine is more commonly used as the main engine and has a much better market. A two-stroke engine can burn low-grade fuel oil and hence reduce the running cost of the ship.
Which is better short stroke or long stroke?
‘It’s because of the higher peak piston acceleration. A long bore engine, as the name suggests, has a longer cylinder. These engines reach their peak torque at a lower rpm when compared to a short-stroke engine. These are more efficient engines and are moreover used in commercially selling cars.
What are the advantages of long stroke engine?
Now, while the power produced by a typical long stroke engine is relatively less, it has its own advantages. These engines produce a much healthier torque at the lower range of the rev spectrum lending themselves to torquey, lazy revving machines very well.
