HI Dear, ??
Welcome to my store, hope you will like this product, if you have any question or comment contact with me as soon as
possible. Our product is true brand product, quality and service guaranteed.?
NOTE:
For the use of diesel vehicles: remove the pressure gauge on the temperature sensor on the silencer, and look at the pressure gauge several times under the idling speed. More than 3 pressures indicate that the silencer is cleaned.
HOW TO USE?
The judgment of the fault of the exhaust clogging is based on:
1. The pressure at idle is not higher than 0.08KG/cm2
2. The engine pressure does not exceed 0.15kg/cm2 at 3000rpm
Remark: The bad indication area on some exhaust back pressure gauges may not exceed 0.25kg/cm2 at 2500rpm, but from the environmental point of view, the current value should be based on the above mentioned figures.
?
Proper use of the exhaust back pressure gauge:
1. The exhaust back pressure gauge is generally linked to the position of the oxygen sensor or the air-fuel ratio sensor. Therefore, when connecting, pay attention to the tightening torque. Be careful not to oversize (break the screw) or loose it (to prevent leakage). gas).
2. After linking the exhaust back pressure gauge, pay attention to the range indicated when idling, if not more than 0.08kg/cm2, you can increase the engine speed to 3000rpm, check the pressure does not exceed 0.15kg/cm2 (if only from the power aspect) In consideration, it is also possible to use a pressure of not more than 0.25 kg/cm 2 as a criterion for judgment).
3. If the pressure exceeds 0.2kg/cm2 when idling, the flame should be extinguished immediately, and the engine speed should not be increased to prevent damage to the instrument.
4. Since the exhaust temperature is high, the detection time should be as short as possible to avoid damage to the rubber hose parts of the instrument link due to long time high temperature.
5. After the exhaust back pressure gauge is removed, the natural cooling method should be adopted. The temperature cannot be forcibly lowered. When the joint temperature and the outdoor temperature are the same, the instrument can be placed in the box.
