Sentence examples for minimum engine speed from inspiring English sources

In this case friction losses and charge leakage through the cylinder-piston gap become dominant, constrain the engine size, and impose minimum engine speed limits.

The figure shows that the bsfc for the constant-compression-ratio engine changes between 238.5 and 261 g/kW.h passing through a minimum value of 230 g/kW.h at an engine speed of about 1,900 rpm.

The fuel consumption curve in Fig. 2 shows that the minimum fuel consumption is around the midrange of the engine speed.

When the engine speed runs into some positions of the midrange, the fuel consumption drops to the minimum value and the torque reaches its peak.

In internal combustion engines, torque increases, up to a point, with the engine speed.

• Use higher gears to lower your engine speed.

It can include forward and sideways acceleration and deceleration, vehicle speed, engine speed and steering inputs.

If the engine is a steam or gas turbine, or a medium-speed diesel engine, a speed reducer will be essential in order to match the most efficient engine speed to the most efficient propeller speed.

Most devices employed to change the ratio of the speed of the engine to the speed of the driving wheels multiply the engine torque by the same factor by which the engine speed is increased.

Direct-current transmission is occasionally used because it allows propeller speed and engine speed to be completely independent.

The transmission remains a 5-speed automatic, albeit with upgrades and slightly taller gearing to reduce engine speed.
