high-voltage control of emissions device

SummaryExampleProgramsPurposeDefinitionIntroductionMonitoring is a general term for on-going collection and use of measurement data or other information for assessing performance against a standard or status with respect to a specific requirement. With regards to EPA's air quality regulatory requirements, there are two basic types of monitoring with two different functions: A CPMS, also called parametric monitoring, measures a parameter (or multiple parameters) that is a key indicator of system performance. The parameter is generally an operational parameter of t…See more on epa.govField electron emission - Wikipedia electron emission, also known as field emission (FE) and electron field emission, is emission of electrons induced by an electrostatic field.The most common context is field emission from a solid surface into a vacuum.However, field emission can take place from solid or liquid surfaces, into a vacuum, a fluid (e.g. air), or any non-conducting or weakly conducting dielectric.

  • emission control system | Description, Components, Facts

    The device that performs this function is known as the positive crankcase ventilation valve, or PCV valve. To control exhaust emissions, which are responsible for two-thirds of the total engine pollutants, two types of systems are used: the air-injection system and the exhaust gas recirculation (EGR) system.
