Q
What is the difference between a full flow and a bypass oil filter?
+
A
Full flow is where 100% of the oil passing through the same media before entering the engine. Bypass filters are more restrictive and take a portion of the oil and filter out smaller particles that can or have passed through the full flow filter.
Common in heavy duty applications.
Q
What is over pressurisation?
+
A
When the oil pressure valve temporarily sticks, it subjects the entire lubricating system to extreme pressures. Under these conditions the oil filter generally expands as the increased pressure tries to force the filter off the engine. Torch filters are built to withstand 3 times normal operating pressure.
Q
What is the difference between fuel filters used on carbureted systems versus EF
+
A
Generally the carburetted system operates at low pressure and has relatively low flow. Filters are often nylon bodied.
EFI filters are metal bodied, and designed to handle higher pressures and flow. The media can also differ between filter types.
Q
Why do Engineers start with Air filter requirements first?
+
A
Because it is the most important filter. Unfiltered air, with inducted contamination, will cause excessive engine wear.
Q
When should I change my air filter?
+
A
The air filter should be changed in relation to operating environment of vehicle, eg in hot, dusty conditions more regular frequent change period is required. In any case recommend change every 12 months irrespective of conditions or distance travelled.
Q
Why do many air filters have wire screens?
+
A
To provide strength to the filter due to high air flows and provide fire protection in case of backfires.
Q
The oil filter leaked soon after it was installed? Make sure correct filter was
+
A
(a) Check old sealing gasket was removed from engine mounting base plate and that plate isn’t damaged or warped.
(b) Ensure filter was correctly fitted with new sealing gasket.
(c) Check threaded stud isn’t damaged or loose.
Q
If I fit a good quality filter, can I use low quality oil?
+
A
A quality filter will not save your engine from excessive wear if there is prolonged use of a poor quality oil. Low quality oil generally means the oil additives deteriorate quicker, putting more stress on the engine. Make sure you use good quality oil and filters.
Q
Do Torch filters have warranty?
+
A
Yes, so long as the service is conducted by a qualified mechanic following the manufacturer’s specifications.

Q
What is the Nernst formula ?
+
A
A:“R”in the formula is the ideal gas constant;“T" is the absolute temperature of the sensing element; “F” is faraday constant; “p7O2)”is the oxygen partial pressure of the exhaust side;“p(O2)" is the oxygen partial pressure in air. Thus, at a certain temperature, if the reference gas is the air (ie., the reference oxygen partial pressure is known), the E value can be determined by the oxygen content of exhaust. A high voltage(0.6 ~ 1V) is generated between the electrodes when the oxygen concentration is low on the exhaust side of the substrate, and the voltage signal is sent to the ECU and amplified. The ECU processes high voltage signal as a rich mixture, and low voltage signal (about 0.1V) is considered as a dilute mixture. Based on the voltage signal feedback of the oxygen sensor, the computer will dilute or enrich mixture accordingly to reach optimal theoretical air fuel ratio.
Q
What’s the operating principle of the Oxygen sensor?
+
A
A: The principle for concentration cell type oxygen sensor is that the difference of the Exhaust, oxygen partial pressure of the two ZrO₂ solid electrolytes provides concentration.potential. It uses the characteristics of ZrO₂ with oxygen ion conduction and no electron conduction at high temperature. Nernst formula can be used to obtain the concentration potential value.
Q
What’s the Oxygen sensor ?
+
A
A:Oxygen sensor is the major sensor component in electronic fuel injection engine control system, and is the key part to control automobile exhaust emission, reduce pollution to the environment and improve fuel combustion quality of automotive engine. Oxygen sensor is used in the feedback control system of the electronic control fuel injection device, to detect the concentration of oxygen in the exhaust gas and whether the air fuel ratio is lean or rich. lt is also used to monitor theoretical air fuel ratio (14.7:1) combustion in the engine, and provide feedback signals to the computer.
Q
What is “Engine Warning Lights”?
+
A
A: Perhaps the most obvious one yet, but definitely the one most people usually ignore. Although the sensor itself isn’t mounted inside the engine bay, any failure of the NOx sensor will trigger an engine warning light. It’s not a bulletproof method of finding NOx sensor faults and issues, but it does paint a much clearer picture of what your car’s experiencing. Scanning for error codes after a check engine light usually reveals whether you’re dealing with a broken NOx sensor right away.
Q
What is “Unstable idle” ?
+
A
A: Since the ECU has no way of knowing what’s going on with the engine, it has to assume a worst-case scenario. Fuel injectors designed to maintain a constant flow of fuel to the engine will sporadically starve and/or surge, neither of which is good for your car in the long run.
