Due to evaporative
losses, less water is
pumped back in
than is pulled out, so the net effect is fluid extraction.
«What we didn't realize until now is that over the past decade, changes in the global water cycle more
than offset the
losses that occurred from groundwater
pumping, causing the land to act like a sponge.
Stiffer suspension, reduced engine
pumping losses, and a raised top speed - 200 mph with the top up, as opposed to the ordinary GTC's 195 - mph fizzle - make the Speed more potent
than its pedestrian sibling, but Crewe's legendary genius remains.
Although this smaller - displacement turbo four - cylinder has lower internal friction and reduced
pumping loss than a Skyactiv V - 6 would, fuel efficiency drops when the engine is under high load, as the engine runs richer to help keep the cylinders cooler.
Less reliance on the traditional braking system and reduced engine
pumping losses translate into greater electrical regeneration (170 percent more
than the 2005 Civic Hybrid) and ultimately improved fuel economy.
I would think the fluid
pump losses are very small as the requirement is more for flow or presence
than pressure it may be possible to divert the bleed off to the usual cam box lube requirements.
I'm sure that adjusting the valve timing and lift can reduce
pumping losses, but those
losses should be in a different category
than throttle
losses —
pumping losses vs. throttle
losses.
Mazda managed to minimize
pumping loss (20 % reduction) with a continuously variable dual S - VT (sequential valve timing) system on the intake and exhaust valves, enabling the air intake quantity to be controlled by the valves rather
than the throttle.
In addition this transmission has other features designed to reduce oil - churning and oil -
pumping losses (mentioned in the article); it ought to be equal or better
than the ZF 8 - speed which is already very good.
In the Atkinson cycle, the inlet valves are held open longer
than normal to allow a reverse flow of intake air into the intake manifold, thereby decreasing
pumping loss and increasing thermal efficiency.
