A carburetor (also spelled carburettor or carburetter) [1] [2] [3] is a device used by a gasoline internal combustion engine to control and mix air and fuel entering the engine. [4] The primary method of adding fuel to the intake air is through the Venturi effect or Bernoulli's principle in the main metering circuit, though various other ...

ZEV sales requirements, starting from 35% to 100%, are for manufacturers with annual sales between 4,501 and 60,000 vehicles. 100% ZEV mandate by 2035, includes up to 20% of PHEVs by referring them as TZEV (Transitional Zero Emission Vehicle ...
California's emissions standards are set by the California Air Resources Board (CARB). By mid-2009, 16 other states had adopted CARB rules; [14] given the size of the California market plus these other states, many manufacturers choose to build to the CARB standard when selling in all 50 states.

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.
Most modern automotive engines are both water and air-cooled, as the water/liquid-coolant is carried to air-cooled fins and/or fans, whereas larger engines may be singularly water-cooled as they are stationary and have a constant supply of water through water-mains or fresh-water, while most power tool engines and other small engines are air ...
The basic operation of a feedback carburetor: The carburetor would take in a signal from the oxygen sensor and would determine if the mixture was correct; If the mixture needed to be adjusted, a solenoid or stepper motor would move to adjust the AFR; Most included electric chokes for cold starting
