The term NO x represents several forms of nitrogen oxides such as NO (nitric oxide), NO 2 (nitrogen dioxide) and N 2 O (nitrous oxide, also known as laughing gas).In a gasoline engine, NO is the most common form of NO x at around 93%, while NO 2 is around 5% and the rest is N 2 O.
A carbon dioxide sensor or CO 2 sensor is an instrument for the measurement of carbon dioxide gas. The most common principles for CO 2 sensors are infrared gas sensors ( NDIR ) and chemical gas sensors.
Sensors for carbon dioxide are an example of this approach and they have been commercially available for several years. Cross-sensitivity of electronic chemical sensors may also be utilized to design chemical sensor arrays , which utilize a variety of specific sensors that are cross-reactive for fingerprint detection of target gases in complex ...
General Motors has more software problems across its lineup, forcing it to issue a second stop-sale order on its vehicles in the last three months. On Monday, GM put the stop-sale on all 2024 ...
Vehicle emissions control is the study of reducing the emissions produced by motor vehicles, especially internal combustion engines.The primary emissions studied include hydrocarbons, volatile organic compounds, carbon monoxide, carbon dioxide, nitrogen oxides, particulate matter, and sulfur oxides.
A $1 billion project to harness carbon dioxide emissions from a Texas coal plant suffered chronic mechanical problems and routinely missed its targets before it was shut down this year, according ...
