The 4-speed transmission had two first gears: a "special low" good for 1.6 mph and a regular first at 2.25 mph, both at l,800rpm rated engine speed. Sales literature stated a ground speed of 0.75 mph could be obtained in "special low" by throttling back the engine speed, which would result in a low idle speed of about 845rpm.
* as the rated engine speed increase, the power target requires higher boosting, causing lower air utilisation, in spite of a less significant power density increase.
Therefore, the fan power is significant when engine speed is close to rated engine speed. A significant portion of the hydraulic power is seen during loaded bucket boom lifting operation.
Simulations were computed at rated engine speed and the pressure plot was made and compared with the experimental results (Figures 1, 2, 3, and 4).

The economy PTO mode can deliver the power required by many applications at 72 percent of rated engine speed, thus saving fuel.
At the rated engine speed of the DD 15, the axial power turbine, otherwise known as turbo compounding, reaches a rotation speed of more than 40,000 rpm.
Trayless automatic duplexing also allows the imageRUNNER 60 to produce two-sided documents at its fully rated engine speed for enhanced productivity.
The rated engine speed of the printer refers to how fast the print engine can deliver plain text pages.
It features full rotary printing technology, which enables printing technology, which enables printing at rated engine speed regardless of the size of the labels, maintaining maximum productivity.
These include: engine, bore and stroke, rated engine speed, displacement, power, transmission and weight.
The engines in the 916 and 920 models feature Bosch high-pressure distributor-type injection pumps and operate at a rated speed of 2150 rpm, while the 924 and 926 machines have Bosch high-pressure in-line injection pumps and a rated engine speed of 2250 rpm.
