MODE OF OPERATION AND TECHNICAL DESCRIPTION

Because of the serial equipment of motors with oil filters, only course filtration of the order of 35 microns (0.035 mm) is obtained. All particles smaller than this are held in suspension in an additive group (dispersants) and have the effect of sandpaper on the mechanical moving parts.

This oil loaded with metallic fines cause longitudinal scores (scratches) on the points of contact between the cylinder and the piston, as can be seen in the illustration.

Originally flat surfaces on the gliding surfaces in the new vehicle transform into rough surface structures.

The abrasive effect of the particles causes an increase in the gap dimensions in the cylinder - piston area and at all bearing surfaces supplied with oil. The result is an increase in fuel consumption with a decrease in engine power and unsatisfactory exhaust levels. Motor oil consumption stresses the catalytic converter and contributes to more frequent change intervals.

Once the CLEANTECHNICS HIGH-PERFORMANCE FILTER SYSTEMS are installed in older motors there is a regression or smoothing of the gliding surfaces. In new vehicles, there is a consistently clean oil and no scoring and consequently almost wear-free operation.


FUNCTION AND PROPERTIES OF OIL FILTERS

In today's motor building mainstream filtering is used almost exclusively. This arrangement is certainly the most reliable, because all of the oil is filtered before reaching the lubrication points.

Nevertheless, because of the high flow-through quantites, filter fineness has to be limited. 35 microns, absolutely : in other words, no particle larger than 35/1000 mm passes through the filter.
Complementing the mainstream filter, which provides relatively course filtration, CLEANTECHNICS HIGH-PERFORMANCE FILTER SYSTEMS incorporate an additional collateral flow circuit as shown in Figure 2.


Cleantechnics-System

Long term oil change experiments show very clearly that the limiting factor for extended oil change intervals is deposit formation, which is ultimately prevented permanently by an efficient high-performance filtration system.

Here, a partial current of 5 to 10 % of the circulating oil quantity is sent through the CLEANTECHNICS HIGH-PERFORMANCE FILTER in the collateral flow. The low passage rate is necessary to allow appreciably finer filtration. The existing relationship between oil quantity, oil pressure and the filter surface creates the requisites for filter performance of less than 1/1000 mm ; so, any particle of the size of the lubrication gap consequently causes wear and the outcome is a considerable shortening of the service life (lower motor power with increased fuel consumption) of the motor oil.


OIL AGING - THE REASON FOR OIL CHANGE

The high loads imposed on motor oil in the internal combustion process causes so-called oil aging.

The oil aging process is affected by

Release of:

• Free radicals
• Acid products of combustion
• Soot
• Metallic wear
• Condensation water


Under the general conditions of :

• High temperature
• Surplus oxygen

It can be seen that oil aging as a collective term for the changes in the properties of used oil can be described by two mechanisms :

• Excessive acidification of by oxidation (radicals, SO2, NOx)
• Thickening by condensation processes resulting from thermal stresses.

Oxidation of the motor oil effected by free radicals from combustion, whereby principally high-molecular weight resins insoluble in oil are formed. These resins serve in the formation of deposits as the binder for the soot produced in combustion. This is a chain reaction that is impaired, in part, by oil additives (anti-oxidants).

Furthermore, the oil is stressed by the acidic gases of combustion (SO2, NOx), which flow into the lower area of the piston through the longitudinal scoring that occurs. Principal in this context is sulfuric acid, which occurs as a result of the sulfur present in the fuel and consumes the alkali reserves (corrosion protection additive and base number).


EFFECT OF WATER IN MOTOR OIL

• Acceleration of aging by catalytic effect
• Hydrolysis of additives
• Corrosion of metallic surfaces
• Damage to seal material

Consequences are, in addition to the direct effects on the motor by corrosion, a rapid breakdown of additives.


METALLIC FINES AND MOTOR WEAR

Even fine metal particles, particularly iron and copper, adversely affect the service life of oil and the motor to a high degree by

• Excess acidity (breakdown of alkali reserves)
• Increase in viscosity (thickness)
• Reduction in dispergence (lubricant capacity)
• Exhaustion of dispersibility (additives dissolving contaminants)
• Deposit formation
• Coating of detergents (additives carrying contaminants).

As the basis for this wear behavior is the fact that in motor operation there is an exponential increase of abrasion particles. The explanation for this in simplified form is that initially larger particles are ground up into many smaller particles and, secondly a particle then rips out another particle from the working surfaces, whereby the result is an exponential increase in the number particles (Figure 1). The advantages of CLEANTECHNICS HIGH-PERFORMANCE FILTER TECHNOLOGY through reduction of the solid matter contaminants is, however, not only in an extension of the motor service life (motor power remaining the same even at max. op. hrs.), but even fuel economy on average of 5 % as a result of the reduced losses due to friction.

 

Insurance Coverage :

Coverage is provided after profession installation of the high-performance oil filter of damage and consequential damage such as to the original oil filter, connecting parts, armored hose and motor and turbine damages to vehicles and utility machines caused by deficient oil performance in the amount of EUR 1.453.456,60.- for each installation (Allianz-Elementar-Vers. AG.) All recommended oil change intervals refer to average conditions of use of motors and equipment. These will be determined by means of an oil analysis done by a technician at no charge.
