Looking for a great way to boost engine function? No matter what kind of car you drive, one of the best ways to improve overall performance is to ensure that the fuel/oxygen mix reaching the engine is optimized and well controlled. An internal combustion engine relies on a combination of fuel and oxygen, the two components required to feed the explosions that keep your car running. Furthermore, it is important for these inputs to have the right relationship to one another and be in the right proportions. A key component that helps to monitor this mix is the oxygen sensor, which is responsible for measuring the percentage of oxygen present in the fuel/air mixture. Too much or too little oxygen can cause decreased performance – so the sensor transmits information to the computerized control system that informs components such as the fuel injectors how to adjust. Furthermore, the sensor plays an important role in monitoring exhaust fumes. If there is too much uncombusted fuel left in the exhaust after it has passed through the engine, emissions will be more harmful to the environment. A well calibrated sensor can ensure that this is kept in check. For great deals on parts that keep your car running reliably, check out PartsGeek.com.
