The superior design of DENSO Lambda Sensors maximises engine performance and fuel

efficiency while reducing harmful emissions.

> Steel core in wires: DENSO Sensors feature special wires, adapted for the harsh

conditions of heat and vibration. The Teflon isolated wires have a core of stainless

steel strands for extra strength, surrounded by nickel coated copper wires for good

conductivity and low resistance.

> Porous PTFE filter: Allows atmospheric oxygen to enter the Sensor without permitting

water or engine contaminants to seep into the casing.

> Stainless steel housing: Resists corrosion and contamination with a rugged, watertight

body.

> Aluminium-oxide double trap layer: DENSO Lambda Sensors feature a unique,

protective coating of aluminium oxide on the ceramic element to help ensure the

Sensor takes accurate measurements and has a long lifetime. The coating helps to

filter contamination out of the exhaust gases, keeping unwanted pollution away from the

ceramic element and preventing an early clogging of the Sensor element and/or damage

to the platinum electrode (of particular value for cars running with low quality fuel). The

aluminium oxide trap layer therefore plays an active role in delivering optimal emissions,

fuel economy, engine performance and prevention of engine damage.

> Double protection cover (on all Sensors): Maintains proper unit temperature for

quicker response times and protects the ceramic element against silicone and lead

poisoning.

Solving the fuel quality dilemma

Poor quality or polluted fuel can have an adverse effect on Lambda Sensor lifespan

and performance - but DENSO Sensors provide the solution.

What causes the problem? Fuel can be contaminated by engine oil additives such as

detergent dispersant or lubricant; petrol additives; sealing compound on engine parts;

and crude oil deposits after desulphurisation. Contaminated fuel can emit a poisonous

vapour if heated over 700 degrees Celcius, which affects the Lambda Sensor by

clogging or poisoning the electrodes. This is a common cause of early Lambda Sensor

failure.

The advanced design of DENSO Lambda Sensors eliminates this danger.

The unique aluminium oxide double trap layer we apply surrounding the Sensor’s

ceramic element protects it from problem fuel; maintaining its lifespan and efficient

performance.
