| E-10 |
| |
A mixture of 10% ethanol and 90% gasoline based on volume.
|
|
| E-85 |

|
| Efficiency |
| |
The ratio of output to input. Volumetric efficiency of a pump is the actual output in gpm divided by the theoretical or design output. The overall efficiency of a hydraulic system is the output power divided by the input power. Efficiency is usually expressed as a percent.
|
|
| Effluent |
| |
The liquid or gas discharged from a process or chemical reactor, usually containing residues from that process.
|
|
| Electro-hydraulic servo valve |
| |
A directional type valve which receives a variable or controlled electrical signal and which controls or meters hydraulic flow.
|
|
| Encoder |
| |
Device attached to a moving chain that produces an electrical signal each time the chain moves a fixed distance. The encoder is attached to the chain and used to track the movement of the pieces through a scanner.
|
|
| Energy |
| |
The ability or capacity to do work. Measured in units of work.
|
|
| Energy crops (Bioenergy crops) |
| |
Are fast-growing crops that are grown for the specific purpose of producing energy (electricity, thermal energy, solid or liquid fuels) from all or part of the resulting plant.
|
|
| Enzyme |
| |
A protein or protein-based molecule that speeds up chemical reactions occurring in living things. Enzymes act as catalysts for a single reaction, converting a specific set of reactants into specific products.
|
|
| Error (signal) |
| |
The signal which is the albraic summation of an input signal and a feedback signal.
|
|
| Ethanol |
| |
A colorless, flammable liquid produced by fermentation of sugars. Ethanol is used as a fuel oxygenate. Ethanol is the alcohol found in alcoholic beverages.
|
|
| Evaporate |
| |
Changing water from a liquid to a vapor form.
|
|
| Excess air |
| |
Refers to the quantity of air supplied that exceeds the minimum necessary to support the combustion chemistry.
|
|
| Externality |
| |
A cost or benefit not accounted for in the price of goods or services. Often refers to the cost of pollution and other environmental impacts.
