Precision engineering, Advanced design and the highest OEM quality; these are the exceptional qualities you'll find in DENSO's range of engine sensors including a guarantee of perfect fitment, reliability and superior on road performance.
The DENSO difference:
DENSO produces both Magnetic Resistant Element (MRE) type and Magnetic Pick-Up (MPU) type sensors.
Responsive: Optimal exhaust gas flow adaptation for all engine temperatures and driving conditions.
Precision: Integrated position sensor allows more accurate control of exhaust gases, resulting in a higher level of precision.
Durability: Reduction in the effect of exhaust pressure and exhaust flow provides carbon corrosion resistance and longer life.
Emission Reduction: Reduced NOx emissions.
The vacuum type consists of an EGR valve. The pressure inside the diaphragm chamber of the EGR valve is changed to adjust the valve opening.
The EGR valve is driven by the DC motor. The motor speed is reduced by a gear and the valve connected to the valve shaft is rotated, adjusting the area of the EGR passage.
The valve opening is detected by the angle sensor, which uses a Hall element, and sent to the ECU as feedback.
The DENSO difference:
Oxygen Sensors (O2) work together with the vehicle's fuel injection system, Catalytic Converter and engine management system or electronic control unit (ECU) to help achieve the lowest possible output of environmentally harmful engine emissions.
Theoretically, at this ratio, all of the fuel will be burned using almost all of the oxygen in the air. The remaining oxygen must be exactly the right quantity for the Catalytic Converter to function efficiently.
The O2 Sensor monitors the percentage of unburned oxygen present in the car's exhaust gases.
According to whether the oxygen content in the exhaust gas is too high (a lean mixture) or too low (a rich mixture) the O2 Sensor transmits a fast-changing, fluctuating voltage signal to the ECU.
The ECU responds to this information by adjusting the air/fuel mixture entering the Catalytic Converter. The goal is to keep the air/fuel ratio very close to the ‘stoichiometric' point, which is the calculated ideal ratio of air to fuel entering the Catalytic Converter.
