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 900. For all other times, the torque available is LESS THAN MAXIMUM POSSIBLE.

4. For a 4 cylinder engine with cranks placed at 900 apart & firing order

1,3,2,4; cylinder 1 (say) has power stroke from 00 to 1800 of crankshaft rotation; then other cylinders will fire as under

• Cylinder 1: 00 to 1800. • Cylinder 3: 1800 to 3600. • Cylinder 2: 2700 to 4500. • Cylinder 4: 4500 to 6300.

For cylinder 1, next power stroke starts at 7200 only & hence it can be seen that from 6300 to 7200, 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 900 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.

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 rpnaik@ntpc.co.in. I assure that concept is fully ready with drawings, animated presentations etc & only shop floor designing / manufacturing is remaining.

2.ALMOST HALF OF THE STROKES ARE NOT CONVERTED EFFICIENTLY IN TORQUE; FORCE IS WASTED IN STRETCHING OR COMPRESSING CRANKSHAFT.

In TEJJ IC Engine, torque wave will be as under:

This torque wave form is clearly superior to existing system INTERMITTANTSINE WAVE TORQUE & will contribute to best efficiencies possible fromAn IC Engine.
