engine speed

engine speed

The RPM of the propeller, compressor, or main rotor of an engine either in the percentage of maximum RPM/power output or actual RPM. In the case of a turbine spool engine, engine speed refers to N1 RPM (the RPM of the low-pressure compressor).

Although lowering engine speed normally means lowered output, this new system is able to generate higher output as the engine's piston stroke is approximately 20 percent extended from the conventional system.
Working with this system is a "one touch" idle control feature, which reduces engine speed to low idle with the touch of a button; a second touch or joystick movement puts the engine back into high speed, allowing the machine to go right back to work.
The objective of the study is to analyze how well the currently working tractor is adapted to the provided work and optimal engine speed as well as what load and fuel consumption are chosen during the operational work of the tractor.
IT sounds too good to be true; sizzling performance, strong throttle response at almost any engine speed and reduced fuel consumption.
Operators, remember to reduce the dozer's engine speed every time you shift in and out of reverse.
The operator chooses either field or transport mode, and the APM system reduces engine speed whenever the implement load allows, automatically reducing fuel consumption and leaving the operator to concentrate on the work in progress instead of having to manually shift gears at just the right time and adjust the engine rpm with the throttle.
The drive unit powers the supercharger's low-inertia compressor independent of engine speed, and can accelerate it from its idle speed of 5,000 rpm to 70,000 rpm in less than 0.
Fuel injection system must be able to meter the desired amount of fuel, depending on engine speed and load, and to inject that fuel at the correct time and with the desired rate.
5-litre V6 engine power has risen to 313bhp at 6,800rpm and torque is now rated at 358Nm at 4,800rpm, while the maximum engine speed has increased by 500rpm to 7,500rpm.
The belt-driven supercharger operates at low engine speeds, with the exhaust-driven turbocharger coming in as the engine speed increases.
It automatically accelerates the feed system when the engine load is light, slows when the load is high and reverses engine speed drops.
Costing pounds 760 the performance pack boosts power from about 130bhp to around 155bhp at the same engine speed.
