volumetric efficiency

n
1. (General Engineering) the ratio of fluid delivered by a piston or ram pump per stroke to the displacement volume of the piston or ram
2. (Automotive Engineering) the ratio of air or gas-air mixture drawn into the cylinder of an internal-combustion engine to the volumetric displacement of the piston

Class 2 MLCC capacitors have higher volumetric efficiency and other unique characteristics not found in the Class 1 MLCC capacitors.
Traditional low heat rejection (LHR) engines employed with thick ceramic TBCs have caused constant high temperature during the entire engine cycle over all four strokes including intake stroke which had adverse effects on engine volumetric efficiency and higher in-cylinder temperature that promoted NOx formation [5, 6, 7, 8, 9].
It is used to achieve greater volumetric efficiency, to make up for pressure loss due to altitude, or to garner more horsepower from a given engine displacement.
A higher viscosity will increase the volumetric efficiency of the pump, increase the volume output, and can improve the system response time.
* Extrexx6 class gear pump: This new and reportedly unique melt pump delivers the needed volumetric efficiency at the highest counterpressures and with the lowest amount of shear stress.
The pumps can fill tanks with large volumes of liquid as well as transfer the liquids across 40 meters of piping to different tanks for fermentation, filtering and bottling with volumetric efficiency and consistency.
An in situ compressor volumetric efficiency can be defined as the ratio of the volumetric flow rate of the refrigerant computed upstream of the compressor suction to the volumetric displacement of the compressor.
The volumetric efficiency of the all-metal screw pump can be calculated using Eq.
Available in the molded EE (7343-43) case code, the capacitors released today offer up to 25% better volumetric efficiency than similar devices, which allows for higher capacitance and voltage ratings.
Using 3D sensors and camera technology housed in a compact device mounted overhead and just inside the dock door, the system's hardware, software and analytics integrate with enterprise resource planning systems to track volumetric efficiency, load rate and when a load is nearing completion.
The engine's volumetric efficiency is directly depended on its ability to push out the exhaust gases effectively to suck in more air for combustion.
Both models feature a single overhead cam four valve per cylinder design that increases volumetric efficiency. These motors are lighter than their predecessors by 13 pounds and have stepped up to 1.8-liter displacement.
