Sentences with phrase «efficiency at higher rpms»

The Atkinson cycle sacrifices low - end torque for greater efficiency at higher rpms, the low - end torque being supplied by the electric motors in a hybrid.
In DOHC engines a shorter stroke and a larger piston can allow for a higher RPM and more efficiency at higher RPM's due to less reciprocating weight related to the connecting rods, pistons and crankshaft.

Not exact matches

With an automatic transmission this is very difficult because if you try to run the engine at wide open throttle the automatic transmission will extend your shift point up to the high RPM range and you will get very bad BSFC and in turn efficiency.
The improvements in low - RPM performance, which is where most street - driven automobiles operate a majority of the time, occur in trade for a power and efficiency loss at higher RPM ranges.
This increases efficiency at low RPMs and a lot of power is accessible at high RPMs; definitely more than a VVTi.
VTEC (Variable Valve Timing & Lift Electronic Control) is a system developed by Honda which was said to improve the volumetric efficiency of a four - stroke internal combustion engine, resulting in higher performance at high RPM, and lower fuel consumption at low RPM.
By operating the engine at higher load and at lower rpm, optimal efficiency can be obtained.
The inertia effect greatly enhances cylinder filling efficiency and the torque produced by the engine at higher rpm.
The effective - compression ratio is less than 9:1 at low - rpm speeds for good drivability and much higher at high engine speeds for increased efficiency and power.
Eco shifts gears early for better fuel efficiency, Sport shifts gears at high RPMs to extract optimum power while Manual lets you choose the gears though it shifts automatically after redline.
This kept torque levels at near - peak levels throughout the rev range and allowed a higher maximum horsepower without killing fuel efficiency or hindering drivability at lower rpm levels.
Every 2013 GMC Sierra HD features a standard 6.0 - liter Vortec V8 with cam - in - block variable valve timing (VVT), which provides more power at high rpm and better fuel efficiency.
