Sentences with phrase «frictional losses in»

Not exact matches

For example, when a normal tire travels over water at a high speed, pressure builds until a film forms to lubricate the interface; this is called hydroplaning, and results in a complete loss of frictional control.

When the tip of the microscope oscillates over certain surfaces, in this case over NbSe2 (niobium selenide), peaks of «dissipation» (i.e., loss of energy) can be seen when the tip is at specific distances from the surface, as if it were held back, at certain locations, by some frictional force.

A better sealing piston will keep more power in the cylinder, but you'll see additional frictional losses.

The 4.7 - litre V8 engine is fundamentally the same as in the regular GranCabrio but internal tweaks including a new coating for the crank and valve gear, have reduced frictional losses.

Four - wheel - drive systems tend to be quite heavy and some of the engine's power can be lost through the various differentials in the car, in addition to the frictional losses of the powertrain.

On the flip side however 3 of the 6 shift elements are disengaged / open for any given gear, as compared to 2 for the Ford 10R design thereby giving Ford the slight edge in parasitic frictional losses.

Several innovations by Maruti and Suzuki engineers to improve fuel efficiency include changes in engine hardware leading to improved thermal efficiency, reduced frictional losses and changes in engine calibration.

What efficiency you gain in being able to pick any engine speed, you lose in frictional / parasitic losses.

While the compact combustion chamber and higher compression ratio on gasoline engine helps to improve engine efficiency, the advanced thermal management system in diesel engine along with low friction engine oil and modified fuel injection system help diesel engine in faster warm up and lower frictional losses.

The latter offer performance and efficiency benefits beyond their simple reduced mass — reduced frictional and rotational losses contribute up to 0.4 L / 100 km of the 3.2 L / 100 km fuel economy advantage Porsche claims the Panamera delivers in comparison to comparable «large luxury four - doors in the 400 and 500hp class».

It also gets a new Honeywell variable geometry turbocharger that suffers nearly 50 per cent less in frictional losses thanks to new bearings.

«Our technical partners are also looking at ways to put Corvette Racing in front in the Green Challenge, whether it's Michelin tires with reduced rolling resistance or Mobil 1 lubricants that minimize frictional losses and improve fuel economy.

The increase in power and efficiency over the former model ensured in this way results from consistent optimization of the combustion chambers, the charge system and the cylinder head, as well as the new arrangement of the ancillary units helping to reduce frictional losses to an even lower level than before.

In addition, this eliminates frictional losses due to residual slip when the brakes are not being applied.

Because of this, it must roll into new contracts as the old ones near expiration, which leads to frictional trading costs as well as losses when the oil market is in contango.
