In 1976 Volvo presented a world first-catalytic exhaust emission control with the Lambda Sond. ... When the exhaust gases come into contact with the precious metal they are converted into harmless substances already to be found in the air.

What is Volvo Lambda sond?
Called the “Volvo Lambda-sond system”, it is applied to the 4-cylinder in-line B21 engine, and employs three essential new components - an exhaust gas composition sensor, an additional feed-back loop to the continuous fuel injection system, and the catalyst.
How does the lambda sensor operate?
Your lambda sensor converts the amount of oxygen present in your exhaust into an electric signal and sends the signal to the computer that controls your engine operation. The ECU (engine control unit) processes the readings and sends the information back to the engine.
How do I know if my lambda sensor is working?
To check the lambda sensor, check the tension at the signal wire (in general black color). Usually, after the engine is warm and under normal operation the measurement should alternative between 0.1 and 0.9 volts around two times per second at 2000rpms.
What is exhaust lambda reading?
Lambda reading on the emission test is the oxygen content of the exhaust gas,if the other readings are ok its normally a hole in the exhaust allowing air to be drawn in (perhaps cracked manifolds/leaky joints in the system).Holding the revs up higher helps but the test should be taken between 2500 to 3000rpm.
Who invented Lambda sond?
An oxygen sensor (or lambda sensor, where lambda refers to air–fuel equivalence ratio, usually denoted by λ) is an electronic device that measures the proportion of oxygen (O2) in the gas or liquid being analysed. It was developed by Robert Bosch GmbH during the late 1960s under the supervision of Dr. Günter Bauman.
When did Volvo start using catalytic converters?
In 1976 Volvo Cars presented a world first in the environmental area – the three-way catalytic converter with Lambda sensor for exhaust emission control. Today, 30 years later, virtually all petrol-engined cars built around the world are fitted with this ingenious and environment-saving component.
What problems can a faulty lambda sensor cause?
If the lambda sensor is defective, no data will be sent to the ECU, which will then use faulty information. This will most likely increase the fuel consumption, and subsequently, the polluting emissions. Eventually, this may lead to the clogging of the catalytic converter, which you will then have to replace.
Can a lambda sensor be cleaned?
The oxygen sensor is an important part of a car engine. ... If you suspect that your oxygen sensor may be dirty, you can clean it by first removing the sensor from its housing in the vehicle, and then soaking the sensor in gasoline overnight.
What causes lambda sensor failure?
Lucas said: “The lambda sensor operates in extremely high temperatures so damage to the heater element of the sensor is the most frequent fault associated with this part. “Vibration or damage to connectors and/or wires can also cause failure. “Another common cause of premature failure is contamination.
Can I drive with a faulty lambda sensor?
Yes, you can drive with a bad oxygen sensor if you can still start your engine and feel little difficulty driving. But don't leave it alone for over a couple of days, as it might cause safety problems and lead to the malfunction of other parts of your vehicle.
Can a faulty lambda sensor cause a misfire?
A malfunctioning Lambda sensor may send an erroneous signal that the air/fuel mixture is too rich. The vehicle's computer will make the correction according to the signal that the Lambda sensor sent, decreasing the amount of fuel in the ratio, causing the spark plugs to misfire.”
What is a knock sensor?
About Knock Sensor
A sensor that detects the knocking vibration of the engine with piezoelectric ceramics, used in spark advance control, will contribute to the improvement and fuel economy of the engine performance.
What is lambda control?
Lambda controller is used to control the excess fuel injection in the combustion chamber of a marine engine when there is a change in the engine load i.e. during a momentary increase in the engine load. This is done by controlling the two main elements which are responsible for combustion- fuel and air.
What is car lambda tuning?
Lambda, is a Greek letter demonstrated by the symbol λ, and means a lot of things in differing scientific fields. In engine tuning, it is a ratio between the amount of oxygen actually present in a combustion chamber vs. the amount that should have been present to obtain perfect combustion.
