It is necessary to maintain an exact air/fuel ratio in order to comply with the required vehicle emission limits prescribed by the law. To achieve this, you need to ensure that you have properly working fuel injection system components that would provide your car with an accurate airflow and fuel flow. Among the indispensable parts that comprise your entire fuel injection system is the air mass meter. This car component can be usually seen adjacent to the air filter assembly inside your engine compartment. Also known as an air flow meter, the air mass meter serves a basic role of regulating the airflow that is being delivered to the air intake system in your internal combustion engine. As an air consumption mass measurement system, the air mass meter works through the principle of hot meter anemometer principle. It does this by sending an electronic signal to the onboard computer of your car as a response to the amount of fluid flow in your engine. Gasoline engine cars can either be equipped with a hot wire or a vane meter type of air mass meter. A hot wire determines the air mass into the engine by heating an electrical wire that has been suspended in the air stream. On the other hand, a vane meter sensor features a spring loaded arm that is used to measure the air volume in the intake air stream of your engine. Just make sure that you keep contaminants on the electrodes inside this fuel injection component. A contaminated air mass meter would result to poor idle or hesitation in acceleration. When your stock air mass meter needs replacement, it would be wise to consider some specifications like fluid temperature range, operating pressure, accuracy and mass flow rate range. Do not look much farther, because you can purchase a highly durable air mass meter at our online store—at a very reasonable price!
