Llinell Amser Newidiadau
Mae’r llinell amser yma yn dangos y fersiynau gwahanol a gymerwyd o EUR-Lex yn ogystal ag unrhyw fersiynau dilynol a grëwyd ar ôl y diwrnod ymadael o ganlyniad i newidiadau a wnaed gan ddeddfwriaeth y Deyrnas Unedig.
Cymerir dyddiadau fersiynau’r UE o ddyddiadau’r dogfennau ar EUR-Lex ac efallai na fyddant yn cyfateb â’r adeg pan ddaeth y newidiadau i rym ar gyfer y ddogfen.
Ar gyfer unrhyw fersiynau a grëwyd ar ôl y diwrnod ymadael o ganlyniad i newidiadau a wnaed gan ddeddfwriaeth y Deyrnas Unedig, bydd y dyddiad yn cyd-fynd â’r dyddiad cynharaf y daeth y newid (e.e. ychwanegiad, diddymiad neu gyfnewidiad) a weithredwyd i rym. Am ragor o wybodaeth gweler ein canllaw i ddeddfwriaeth ddiwygiedig ar Ddeall Deddfwriaeth.

DEFINITIONSU.K.
Exhaust gas analyser | An exhaust gas analyser is a measuring instrument that serves to determine the volume fractions of specified components of the exhaust gas of a motor vehicle engine with spark ignition at the moisture level of the sample analysed.
These gas components are carbon monoxide (CO), carbon dioxide (CO2), oxygen (O2) and hydrocarbons (HC).
The content of hydrocarbons has to be expressed as concentration of n-hexane (C6H14), measured with near-infrared absorption techniques.
The volume fractions of the gas components are expressed as a percentage (% vol) for CO, CO2 and O2 and in parts per million (ppm vol) for HC.
Moreover, an exhaust gas analyser calculates the lambda value from the volume fractions of the components of the exhaust gas.
|
Lambda | Lambda is a dimensionless value representative of the burning efficiency of an engine in terms of air/fuel ratio in the exhaust gases. It is determined with a reference standardised formula. |
