Hi,
I wrote this letter, because I think that I have few interesting
technical ideas, and I would like to know that what are your opinion
of these.
In this letter I would like to sending for you a short information
sheet from my one ideas, which is a "Variable Valve Gear".
VARIABLE VALVE GEAR:
I would like to enumerate those mechanical components in this place
whiches are in this mechanism, that you can understand the working:
1.:Crankshaft
2.:Camshaft with the induction valves. ( I.Camshaft )
3.:Camshaft with the exhaust valves. ( E.Camshaft )
4.:Timing belts(or timing chains)
5.:Timing belt tensioner with a spring. ( S.Tensioner )
6.:Timing belt tensioner with a electric servo motor. ( E.Tensioner )
Working:
In this engine conception is two camshafts. One camshaft with the
induction valves and the other camshaft with the exhaust valves.
Between the crankshaft and the I.Camshaft is one timing belt, and
between the crankshaft and the E.Camshaft is the other timing belt.
One timing belt has two side when the engine working: the strech side
and the slack side. If we see one timing belt's mechanism then is one
E.Tensioner on the strech side, and is one S.Tensioner on the slack
side. The E.Tensioner has a self locking screw worm drive (or double
worm drive) between the tensioner and the electric servo motor. If we
see one moment when the engine working, and in this moment the
crankshaft is on the Top Dead Centre (TDC) then the E.Tensioner's
moving can regulate the camshaft's position, and with this can
regulate the valve timing circle. When we strech the timing belt on
the strech side with the servo motor then we can regulate the camshaft
position and with this we can regulate the engine's gas exchange
process. The E.Tensioner's moving regulate the timing belt length on
the strech side (between the crankshaft and a camshaft), and this
going to regulate the camshaft position if we see that moment when the
crankshaft is on the Top Dead Centre. From this mechanism is one on
the E.Camshaft's timing belt and is other one on the I.Camshaft's
timing belt too, and therefore with this possible to regulate the gas
exchange process at the induction valves and at the exhaust valves
too. Instead of the electric servo motor possible to use a
hidraulic-mechanic mechanism too. I think that this has few
advantage, but in a prototype better the electronic system because
this can see more degrees on the engine's revolution, and because in
this are few potentiometer whiches with possible to adjust that places
on the revolution where the servo motorīs moving going to put on, and
with these possible to regulate the servo deflection's size in one
degrees. (Possible to use 8-16 degrees.) Every degrees has two
adjusting potentiometers in the electric control circuit. With the
first I can regulate that place of the revolution where the servo
motorīs moving going to put on. With the second I can regulate the
servo deflectionīs size. In the control circuit is a other
potentiometer too which with possible to regulate all degrees of the
global control circuit. Than have to use this when for example the
engine is cold or if the engineīs revolution is permanent and then the
engine get bigger or smaller loading. Indirectly this electric control
circuit see the engineīs revolution. In the electric control circuit
is one or more LM324 chip. One chip can regulate 4 degrees.
(From this Electric Control Circuit I have a circuit diagram plan.)
P.S.:
With this ideas first I tried to find for myself a job at 1996, but
the "Variable Valve Gear" was the single idea from which I sent
confidential details for car factories and for other peoples. I gived
for they that my offer that if a factory or a people can give for me a
whatever work in abroad than I going to give all my ideas for that
factory or for that people.
Therefore I would like to sending for you a list from my ten as ideas
whiches I can give for you, if you can give me something work:
I want to declare that those ideas whiches over I dispose borned
in my own head and I didn't use nothing illegal method when I made
these. These ideas donīt have patents to the best of my knowledge.
1. -I found a mechanism which with possible to built the "Variable
Valve Gear" without electrical construction. This hidraulic-mechanic
mechanism is a control unit which can see chiefly the engine's
revolution. This is for that reason important because the electric
servo motor get very big loading in the electrical construction.
2. -I have a air-conditional plan which has very small energy
consuption and manufacturing expenses.
3. -I have a valve mechanism which usable only in very big engines and
which can open and close the valves quicklier than a camshaft. This
usable if a engine has small revolution.
4. -I have a economiser plan which with possible to save up about 1O%
diesel oil or petrol. In this plan are a special fuel injector plan
and a special engine working plan.
5. -I have a cylinder head plan which has very smaller energy
consuption than a traditional cylinder head.
6. -I have a very simple idea which with possible to reduce the
attrition on the cylinder wall.
7. -I have a cylinder head plan which with possible to operate the
engine than a two-stroke engine or than a four-stroke engine. Between
the two system don't have to stop the engine. This is for that reason
important because if have to use big wattage then possible to turn on
the two-stroke system when the car run.
8. -I have a wheel suspension plan.
9. -I have a plan which with possible to reduce the engine's fray when
is the engine's start.
10. -In this last paragraph are three small idea whiches aren't very
difficult and expensive ideas, but with they possible to do fashion
for a type of car. etc.
Please study my letter and if you show interest in my offer, and you
can help me that I can faind a whatever job or work than please get in
touch with me. If you don't can help me but you know somebody who
perhaps show interest in my offer,than please send for me that
people's address.
Thank you very much.
