Final answer:
Fuel consumption check and monitoring is performed through several methods and procedures including EPA fuel economy tests, real-world fuel economy data contributed by drivers, and the use of fuel and temperature gauges in vehicles.
Step-by-step explanation:
Fuel consumption check and monitoring is performed through several methods and procedures. One method is through the use of EPA fuel economy test results that manufacturers are required to provide for their vehicles. These tests measure the volume of carbon captured from the exhaust during specific certification tests. Additionally, the EPA has implemented a program called 'Your MPG' which allows drivers to contribute real-world fuel economy statistics to a database and compare them with the original EPA test results.
Another aspect of fuel consumption monitoring is the use of fuel and temperature gauges in vehicles. These gauges are voltmeters that register the voltage output of 'sender' units, which are proportional to the amount of gasoline in the tank and the engine temperature.
In summary, fuel consumption check and monitoring involves EPA fuel economy tests, real-world fuel economy data contributed by drivers, and the use of fuel and temperature gauges in vehicles.
