This paper proposes a low-cost, high precision and efficient throttle-less hydraulic circuit that utilizes off-the-shelf industrial elements to control single rod hydraulic cylinders.
Experimental new dispatching and control systems may soon tell engineers if they are using the most fuel-efficient throttle settings.
Reducing aerodynamic drag only realizes its full savings if the car's engine size is reduced to meet the lower requirements, because the gasoline engine becomes less efficient when the throttle is less open, partially offsetting the lower work done if the engine size is the same.
An efficient way of throttling a turbine engine back to cruise power is to reduce the density of the inlet air.
Proton-generated Alfvén waves trap particles near the shock for efficient acceleration but also throttle the intensities at Earth to the "streaming limit" early in the events.
Overdrive saves you gas mileage at higher speeds by using a lower ratio from engine speed to wheel speed - this places the engine at a more efficient operating point (by reducing throttling losses, etc).
Engines are most efficient with moderately high air flow (throttle) and at revolutions per minute (RPM s up to their power peak (for small to mid sized engines this is generally somewhere between 4k to 5k RPM).
Turbocharging allows automakers to get the same power out of a smaller, more efficient motor — though the efficiency generally goes away if you're hammering the throttle.
The motor will be only 90 percent efficient; so pumps, motors, drive trains and throttling valves along the way will lose more, leaving the plant with 93 units of energy.
Condensate throttling is one of the few efficient methods which can be used to rapidly activate stored energy enough for unit load support.
Econ model is fuel-efficient mode, this model can save fuel, but throttle's response speed reduce somewhat than the Carmax, by plus, minus button to adjust the sensitivity in this mode, until reaching appropriate value you think.
