An Evaluation of Methods of Introduction of Top Cylinder Lubricants
- It is difficult to establish the benefits of upper cylinder lubricants which are added to the prime
effect of such additives in combination with the crankcase oil. It must be recognized that mere
dilution of the crankcase oil is not the answer to top cylinder lubrication. If the normal channels
of lubrication of an engine are blocked by carbon, gum, varnish or sludge and the flow of oil or oil
vapor to certain points has been blocked it is not reasonable to assume that material, which is
added to the crankcase oil, will reach such working parts. It has been established that minutes
elapse in the operation of a cold engine before any oil or oil vapor reach certain moving parts. It
is reasonable to assume that material which is added to the crankcase oil would involve this same
condition with respect to primary lubrication.
- The addition of properly compounded top cylinder lubricants to engine fuel provides for some
added lubrication within an engine. The difficulty is associated with the correct proportion of
top cylinder oil to engine fuel since the addition of a sufficient volume of oil to provide adequate
lubrication would result in a decrease in the octane value of the base fuel. There are other
complications involved with oil treated gasoline. A basic difficulty is related to the fact that
acceleration of an engine results in a high fuel and oil input coincidentally and engine deceleration
provides for low fuel and oil ratio as at starting or during extended idling periods. Treated fuels
cannot provide for high oil to fuel input during any period of operation of an engine.
- Conventional methods of introducing top cylinder oils into an engine by lubricating devices have
resulted in the use of oilers which meter drops or slugs of oil into the intake manifold. A drop of
oil on a cold metal surface is ineffective within the intake manifold. A drop or slug of oil,
introduced into the intake manifold below the point of carburation, does not provide for the
even distribution of the lubricants throughout an entire upper cylinder engine assembly and to all
cylinders or in proportion to the fuel input into each combustion chamber.
- Shot-in-the-arm methods of loading an engine with top cylinder oil through the carburetor air
intake may provide for the temporary relief of clogged rings or stuck valves and induce an
increase in cylinder compression factors. The result must be temporary since the method is
designed only to involve spark plug efficiency and combustion residues inherent in such a
method. It is obvious that such a method is not to be considered a part of the lubrication
system of an engine.
- The AMPCO method of introduction provides for the introduction of a completely dispersed oil
spray or vapor into the intake manifold of an engine. The AMPCO unit operates to meter a
minimum quantity of oil into the line and discharge it below the point of carburation as an oil
spray, throughout the complete normal range of engine vacuum. Since vacuum is created
within an engine on the intake stroke, the oil spray is distributed evenly to each cylinder before
ignition occurs to provide pre-lubrication of parts within the upper cylinder section of an engine.
- The AMPCO system of pre-lubrication is essential to adequate compression, sufficient ring and
cylinder wall lubrication and reduction of blow by in a cold engine. Except for the residual oil
which may be in this engine at starting, there is no way to provide pre-lubrication before ignition
other than to introduce an immediate oil spray with the fuel on the primary or vacuum stroke of
an engine.
- The AMPCO method of top cylinder lubrication provides the singular advantage of a high oil to
fuel ratio within an engine during specific periods of road operation. The normal operation of an
engine provides for periods of acceleration and deceleration with synchronous fluctuation of fuel
input and engine vacuum. The intermediate engine characteristic of low fuel input and high
engine vacuum provides for the introduction and distribution evenly to all cylinders of the upper
cylinder lubricant with a high oil to fuel ration which is effective for the purpose of lubrication
without fuel dilution.
- The standard AMPCO Lubricator provides for a three to one ratio of oil input in relation to engine
vacuum which is sufficient for adequate upper cylinder lubrication and results in the consumption
of one quart of lubricant during two thousand miles of operation with normal oil control valve
setting. The heavy-duty AMPCO Lubricator provides for an adjustable flow control with which it
is possible to establish the input rate as determined by the vacuum curve, load factors and fuel
consumption of any engine. Both units introduce the lubricant as a completely dispersed oil
spray or vapor throughout the entire range of normal engine vacuum.
- A summary of operating characteristics which are exclusive with the AMPCO system and of
advantage to engine operation and durability include the following factors:
- A permanent method of providing controlled upper cylinder lubrication to an internal
combustion engine. - A method which ensures the even distribution of an upper cylinder lubricant throughout
an entire upper section of an engine. - A lubrication system which provides upper cylinder lubrication before ignition occurs within
an engine. - A method of introducing an upper cylinder lubricant which provides for a high oil to fuel
ration during normal operating intervals to afford undiluted engine lubrication in the heat-
wear zone.
