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 the advantage of a longer 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.

What is the difference between me B and Me C engines?

ME engine electronically controls fuel injection, cylinder lubrication, and the timing on elements such as the exhaust. There are two versions of ME engine, ME-C uses electronic control on both fuel injection (FIVA Fuel Injection Valve Activation) and the exhaust valve (ELVA Electronic Exhaust Valve Activation).

Why is it called super 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.

Who makes MAN marine engines?

MAN SE
MAN Diesel SE was a German manufacturer of large-bore diesel engines for marine propulsion systems and power plant applications….MAN Diesel.

Are MAN trucks German?

Headquartered in Munich, Germany, MAN Truck & Bus produces vans in the range from 3.0 to 5.5 t gvw, trucks in the range from 7.49 to 44 t gvw, heavy goods vehicles up to 250 t road train gvw, bus-chassis, coaches, interurban coaches, and city buses. MAN Truck & Bus also produces diesel and natural-gas engines.

Does a longer stroke make more torque?

Instead, long-stroke engines produce higher torque at lower RPMs. For example, the Sportster produces 73.2 Nm of maximum torque at 3,750 RPM, while the Street Triple produces 78.6 Nm at 9,350 RPM. A longer-stroke cylinder usually has a narrower combustion chamber.

Is a longer stroke engine better?

For a given engine speed, a longer stroke increases engine friction and as a result, increases the stress on the crankshaft. ‘It’s because of the higher peak piston acceleration. A long bore engine, as the name suggests, has a longer cylinder.

What are the advantages of me engine?

The electronic control of the engine fuel injection and exhaust valves improves low-load operation, engine acceleration, and give better engine balance and load control, leading to longer times between overhauls, also by implementation of enhanced diagnostics systems.

What is FIVA valve in me engine?

Fuel Injection Valve Actuator (FIVA): The FIVA valve controls the fuel oil quantity when the engine is used on both the fuels.

What kind of engine does man B and W use?

MAN B&W Two-Stroke Engines Introduction This paper describes in detail the ser- vice experience of the new generation of super-long stroke S and G Mk 9 type engines. Focus will be on the cylinder condition in general and cold corro- sion control in particular.

What are the advantages of a super long stroke engine?

Advantages of Super Long Stroke Engines August 19, 2018 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.

Why is a super long stroke propeller used?

Why SUPER-LONG STROKE? (since more time is available for fuel combustion). (–>so large diameter propeller can be used –>propeller efficiency increases.) – More time for heat dissipation to cooling water. -higher compression ratio can be achieved.

What kind of engine does MAN Diesel and Turbo use?

MAN Diesel & Turbo follows the development in the shipping market closely and has kept an eye on the trend towards fuel optimisation in recentyears. The company has experienced great interest in the G-type engine from our customers, which has resulted in the development of a complete engine programme in the G-series from 50 to 80 bore.
