Sentences with phrase «in volumetric efficiency»
In passenger cars at low partial loads, a higher swirl level (partial closing of the filling port in a four - valve cylinder head) can lead to a better particle / NOx trade - off, whereby consumption as well as CO emissions increase because of the deterioration in volumetric efficiency [1].

In order to increase the Volumetric Efficiency (VE) of your engine «pump», everything must be balanced to add as much fuel that is needed with any added air.
Higher power does not mean higher mpg and «volumetric efficiency» has nothing to do with fuel efficiency (in fact, higher volumetric efficiency means you suck in more fuel and air per stroke).
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.

To get the best volumetric efficiency at a particular operating point, one must tune the valve events to be in - sync with these pulses.
Dual - overhead cam (DOHC) cylinder heads with high - flow intake and exhaust ports, in combination with variable - valve timing (VVT), allow optimum volumetric and combustion efficiency over the full speed and load range.
Using CVVT on both camshafts has several advantages when compared to using it only on the intake camshaft including an improvement in performance (increased volumetric efficiency) and fuel economy (reduced pumping loss), and a reduction in hydrocarbon emissions
As in Formula One, optimised intake and exhaust port length and profiling have resulted in an evolution of inlet acoustics to a volumetric efficiency of over 100 %.
Using CVVT on both camshafts has several advantages when compared with using it just on the intake camshaft, including a two percent improvement in performance (increased volumetric efficiency), two percent improvement in fuel economy (reduced pumping loss) and a 30 percent reduction in hydrocarbon emissions.
Due to early intake valve closing in the Miller combustion cycle, volumetric efficiency is lower than for an engine with standard valve timing.
In order to achieve the optimum volumetric efficiency in the lower portion of the engine's operating range, rocker arms are programmed to follow cam lobes that provide low lift and reduced duration (shorter time open with less valve liftIn order to achieve the optimum volumetric efficiency in the lower portion of the engine's operating range, rocker arms are programmed to follow cam lobes that provide low lift and reduced duration (shorter time open with less valve liftin the lower portion of the engine's operating range, rocker arms are programmed to follow cam lobes that provide low lift and reduced duration (shorter time open with less valve lift).
The increase in power was made possible by the engine's improved volumetric efficiency through reduced intake load losses and by exhaust backpressures, together with optimized electronic control.
The goal of performance exhaust headers is mainly to decrease flow resistance (back pressure), and to increase the volumetric efficiency of an engine, resulting in a gain in power output.
These advantages include a two - percent improvement in performance (via increased volumetric efficiency), two - percent improvement in fuel economy (via reduced pumping losses) and a 30 percent reduction in hydrocarbon emissions.
To boost volumetric efficiency, the V12 employs continuously variable - length intakes - a mainstay in F1 engine technology until banned by rule changes — which optimise performance as a function of engine speed.
