The oxygen sensor to the motor there are actually two kinds of zirconium oxide and titanium oxide. Together with the car diagnostic tools structural differences, diverse in condition, its wiring single wire, two-wire, three-wire and four-wire factors, the a number of lead the best way oxygen sensor is not an alternative choice to, This paper describes the zirconia oxygen sensor .



The oxygen sensor is surely an important component from the usage of catalytic converters to reduce exhaust pollution engine. The oxygen sensor is located while in the very first section with the exhaust pipe before the catalytic converter. Oxygen auto diagnostic tool Sensor dioxide wrong (a ceramic) produced elements, and its inside of and outside the house are plated having a thin layer of platinum. The misprinted ceramic plated skinny platinum layer at one individual conclude shut. The latter is inserted in to the protecting sleeve, and mounted on a steel entire body. Protective sleeve to perform an extra protecting outcome as well as the sensor may be put in about the exhaust manifold. The outside in the ceramic overall body is exposed within the exhaust fuel, when the internal and environmental ambiance.

This component of minimal temperature higher resistance, small temperature will not allow for present by way of. High temperature, because of to variances from the concentration on the Auto Diagnostic Tool oxygen in the air together with the exhaust gasoline, oxygen ions are in a position as a result of this component. This makes a possible distinction, platinum enlarge. So, when the air-fuel ratio reduced compared to theoretical air-fuel ratio (dense), the outdoors (the environment) while in the oxygen sensor element (exhaust gasoline) concerning the larger sized oxygen concentration difference. So, the sensor generates a relatively potent voltage. Other hand, in case the air-fuel mixture is lean, the oxygen focus variation involving the ambiance along with the exhaust gas is modest, the sensor will generate only a reasonably weak voltage (in the vicinity of 0V).

Once the deviation from your theoretical air-fuel ratio, the air-fuel ratio on the combination gas purifying capability of your three-way catalyst for CO, HC and NOx in a very sharp decrease in oxygen 自動車整備工具 sensor is hence mounted from the exhaust pipe, for detecting the focus of oxygen inside the exhaust gasoline, and also to ECU comments sign to raise or lower while in the gas injection amount on the gas injector, thus to manage the air-fuel ratio of the combination gas during the vicinity of the theoretical value, and afterwards managed with the ECU.
