Filters Liquids Boots
Taking care of people and their cars
There are several filters in motor cars. They all have one common goal and that is to restrict impurities travelling into critical areas in the engine and other systems.
- The air that passes through this filter goes into the piston cylinder where mixed with fuel is ignited by the spark from the spark plug.
- Unfiltered air contains dust, pollen and other fine debris.
- Under the intense heat of the explosion of the fuel vapour these particles are incinerated into hard gritty abrasives.
- These will damage the pistons and side walls of the cylinders.
- As the filters do their job they trap more and more particles in the filter medium.
- This reduces the air flow.
- At some stage they will have absorbed so much debris that the engine will be starved of oxygen resulting in the car not running well.
- Please try this.
- Take a deep breath in through you nostrils.
- Now hold a tissue over your nostrils and take another deep breath in through your nostrils.
- Please double the tissue and you will know how your engine feels trying to run on a blocked air filter.
- There is no point in removing to filter turning it over and banging it on a flat surface. Sure you will remove some of the surface dust but the air permeability of the filter has not improved one little bit.
- For petrol engines fuel filter are there to remove any impurities from the fuel when you fill your car with petrol.
- Dust which is in the air enters the fuel system.
- The fuel filter prevents this very fine grit blocking the injectors.
- With time the fuel filter medium becomes blocked and restricts the flow of petrol to the engine starving it of the fuel which it needs for optimal performance.
- Fuel filters have changed greatly since petrol delivery systems have changed from low pressure to high pressure systems.
- There are still some inline filters between the petrol tank and the injectors.
- Fuel filters are now found inside the petrol tank.
- Changing the filter is a much more complex operation, often requiring the rear passenger seat to be removed
- More engines have been destroyed by oil filters than any other filter on the car
- Due to fuel combustion contaminants are deposited in the engine oil.
- As a result the oil Is thicker and does not flow as easily through the narrow channels leading from the sump to the pistons and bearings.
- In addition oil is consumed during the normal operation of the engine. This means that there is less oil in the sump for circulation through the engine.
- The function of the oil filter is as the name suggests, to trap the burnt carbon particles in the oil and not allow them the to return to the parts in the engine that require constant lubrication.
- As more and more contaminants are trapped the flow of oil flow through the oil filter is impeded.
- The compound effect of the thickened oil due to burn off and contaminant pickup eventually blocks the filter medium completely.
- The filter housing has a release valve which opens and sends the unfiltered oil back into the engine and this is the beginning of the end for your engine.
Regular oil and oil filter changes imperative to protect your engine from premature wear.
A car's cabin/ pollen filter is part of the air-conditioning system,
- Where two metal shafts are joined to each other with either a Constant Velocity, Rubber Doughnut, Universal or slip ring joint they need constant lubrication.
- The two shafts are not in constant alignment. the rubber boot which is filled with grease. Each end is tightly clamped the shafts there by sealing the grease in the boot. The boot expands to accommodate the eccentric rotation of the joint.
- With time the rubber perishes, cracks and the grease leaks out. This is bad on two levels. Firstly the grease leaks out and the joints are no longer getting the lubrication they need to prevent premature wear. Secondly dust and grit enter the boot through the split in the boot. This mixes with the grease to form an abrasive paste which will destroy the joint.
What do the numbers mean. For example 5 W 30 is a multi grade oil.
The 5 is the viscosity of the oil when cold which means it is very thin and runny. The 30 is the viscosity when the engine is at running temperature much thicker and less runny.
These numbers are only the start of the specification. The additives specified by each manufacturer determines which 5W30 (or other combination of number on either side of the the "W") must be used in any particular car engine. We stock 7 variations of 5w30 and over 20 other grades of oil to guarantee that only the correct oil goes into your engine.
|Detergents||Remove impurities to prevent residue build up on engine parts|
|Dispersants||Prevent contaminants in the oil from clumping together|
|Antioxidants||Retard the process of oxidation. Oxidation destroys an oil's ability to lubricate|
|Anti-wear||Bonds to metal surfaces to create a film between moving metal parts|
|Friction modifier||Makes oil more slippery. Reduces wear and improves fuel efficiency|
|Corrosion inhibitor||Prevents corrosion of metal surfaces|
|Seal swell agent||Prevents loss of fluid via gaskets|
|Pour point depressant||Allows oil to remain more fluid at lower temperatures|
|Foam inhibitor||Retards the formation of foam in oil|
