The results offer new inspiration to the design of spin torque oscillator devices that simultaneously process high frequency, narrow output band, and tunable over a wide range of frequencies via external stress.
An output band from 2058 kW to 2430 kW at 240 rev/min is covered by the 6EL38 and 6EL40 engines on a mean effective pressure of around 20 bar.
It took the MAN medium-speed engine program down to cover an output band from 2200 kW to 7920 kW with five, six, seven, eight and nine in-line and V12, 14, 16 and 18-cylinder models.
The 242 mm bore/320 mm stroke DX type is produced in three, six, and eight in-line cylinder versions to cover an output band up to 883 kW at 720 or 750 rev/min.
The in-line six-, eight- and nine-cylinder M32 models have a 480 mm stroke and originally yielded an output of 440 kW/cylinder at 600 rev/min, covering an output band from 2400 kW to 3960 kW at the economic continuous rating (ECR).
An output band from 1490 kW to 4020 kW at rated speeds of 750 1000 rev/min was initially covered but the upper limit from the V16-cylinder model was raised to 4320 kW and then to 5420 kW through improvements in combustion efficiency.
The power gap between the M20 and M32 models was bridged in 1996 by a 255 mm bore/400 mm stroke M25 derivative, which covers an output band from 1800 kW to 2700 kW with six-, eight- and nine-cylinder models running at 720/750 rev/min.
Market demands for higher fuel economy with the capability to burn lower grade bunkers led to the introduction of a a third generation engine, the longer stroke DL series, which includes eight medium speed models with bore sizes ranging from 190 mm to 400 mm and covering an output band up to 4415 kW.
The system is adapted from the difference between the input and the output base band signals.
The filter output for band, frame and filter is referred to as.
