I HAVE DEVELOPED NEW DRIVING MECHANISM FOR BICYCLE/RICKSHAW HAVING FOLLOWING ADVANTAGES OVER CONVENTIONAL SYSTEM.

I AM READY TO SELL THE INVENTION ALONG WITH PATENT RIGHTS / COMMERCIAL DEVELOPMENT & SELLING RIGHTS ON MUTUALLY AGREED TERMS & CONDITIONS.

IN CASE YOUR COMPANY IS INTERESTED, PL. CONTACT ME. MY MOBILE NO. IS +919424140739.

ADVANTAGES OF NEW DRIVING MECHANISM

BY- R. P. NAIK

1. Both legs can drive simultaneously: Due to independent nature of driving both of the legs can be utilised for driving simultaneously whenever required. This will help in dead start or accelerating with high load at step gradients or rough tar rain etc.

2. Continuous driving torque: The driving force on the rear wheel (s) will be a continuous one. As soon as a leg finishes its driving stroke the other leg will start its driving stroke and hence virtually there will be no time of zero torque.

3. More force than driver’s weight can be applied without fatigue: The backrest provided will give support to driver in such a way that by utilizing reaction from backrest, the driver can put on force more than his own weight whenever required.

4. No stress in portion above the waist: Due to same backrest, there will be no stress developed above the waist and back pen and hand tension will be eliminated.

5. More angle turned by thighs & knees ensure more force available when required: Due to position of seat and paddle, the angle turned through by thigh and knee for any stroke of driving will be more than corresponding angle in case of ordinary cycle (rickshaw) hence there will be more work done available per driving stroke of the paddle.

6. Crippled persons can use their able leg: The same system of driving can be utilised for handicapped person’s tricycles. In these, the handicapped person can use his able leg along with his hand for driving the tricycle. If the amputation of a leg is below the knee; than he can use even his stump as well as his able leg for driving with the help of suitable padding and paddle modification.

7. Easy adaptability for existing manufacturers: Once this system proves its utility and is accepted for increased speed /load carrying capacity of rickshaw, the existing cycles or rickshaw manufactures can easily convert to this design without altering many of their facilities.

8. Gear arrangements: Suitable gear arrangements will enhance speed / load carrying capabilities tremendously.

Tejj constant torque ic engine

TEJJ IC ENGINE
(CONSTANT TORQUE RECEPROCATING IC ENGINE)
In all IC engines built so far, the reciprocating motion of the connecting rod
is converted in to rotary motion for wheel through crankshaft. This was
most appropriate technology when the engine was invented. However, with
continuously rising fuel prices around the world, many attempts are being
made for improving engine efficiency.

I have studied existing technology in detail & have found out following
disadvantages with existing system.

DISADVANTAGES IN EXISTING SYSTEM
1. The torque generated is always in a sine wave form.
2. Although, fuel combustion exerts tremendous force on piston from
TDC to BDC (can be considered constant for any particular power
stroke); all of it is never converted in to desired torque. When piston
is near TDC or BDC, the force is wasted in compressing / stretching
crankshaft radial arms towards / away from crankshaft bearings. Due
to this repetitive cyclic force, crankcase is required to be designed
adequately strong & robust for bearing non converted force from
Pistons.
3. Due to sine wave nature of torque conversion, maximum torque is
available ONLY AT CRANKSHAFT ROTATION AT MULTIPLES OF 90 deg..
For all other times, the torque available is LESS THAN MAXIMUM
POSSIBLE.
4. For a 4 cylinder engine with cranks placed at 90 deg. apart & firing order
1,3,2,4; cylinder 1 (say) has power stroke from 0 deg. to 180 deg.of
crankshaft rotation; then other cylinders will fire as under
· Cylinder 1: 0 deg. to 180 deg..
· Cylinder 3: 180 deg. to 360 deg..
· Cylinder 2: 270 deg. to 450 deg..
· Cylinder 4: 450 deg. to 630 deg..
For cylinder 1, next power stroke starts at 720 deg. only & hence it can be
seen that from 630 deg. to 720 deg., there is no power available in any of the cylinders. Engine has to cross this zone only by means of inertia of
the over all system.

Considering all these disadvantages, I have developed a new concept in IC
Engine, which WILL NOT HAVE ANY OF ABOVE DISADVANTAGES.
I have named it TEJJ IC ENGINE having following advantages:

ADVANTAGES OF TEJJ IC ENGINE
1. This Engine WILL PRODUCE CONSTANT TORQUE OVER ALL
POSITIONS OF CRANKSHAFT ROTATION. Torque wave will be a
rectangular one.
2. The torque will be comparable to that of ELECTRIC MOTOR.
3. As no force from piston will be wasted in exerting undue force on
crankshaft bearings, crankcase design can be made relatively
lighter.
4. Torque available will be EQUAL TO MAXIMUM POSSIBLE TORQUE of
existing sine wave torque at 90 deg. multiples.
5. This engine can be easily made in existing plants since It is only
addition / modification of components & rearrangement of existing
engine using ALREADY PROVEN COMPONENTS ELSE WHERE.
6. No new technology yet to be tasted is used for this invention.
7. Work done PER POWER STROKE of ENGINE WILL BE ALMOST 55%
HIGHER THAN THAT IN AN EXISTING SINE WAVE IC ENGINE.
8. This will lead to TREMENDOUS INCREASE OF ENGINE EFFICIENCY /
MILAGE FROM VEHICLE.
9. This Engine can be used for all IC engine applications as at present.
10. This Engine can be used for all 2-stroke / 4-stroke engines running on ANY FUEL.

IN CASE ANY INDIVIDUAL / INSTITUTE / MANUFACTURER IS READY FOR
SPONCERING DEVELOPMENT OF A PROTOTYPE OF THIS NEW ENGINE;
KINDLY CONTACT ME ON MOBILE NUMBER 919424140739 OR E-MAIL
Rp_naik@in.com. I assure that concept is fully ready with drawings,
animated presentations etc & only shop floor designing / manufacturing is
remaining.
