Changing Times: Two on 'Best Engines' List Aren't Really Engines
By Bill Visnic December 8, 2010The Ward's Automotive Group says it's embracing the future of vehicle electrification by naming an electric motor and a substantially electric propulsion system to its annual "10 Best Engines" list for 2011.
Neither Nissan Motor Co. Ltd.'s Leaf, which doesn't use an "engine" at all, or General Motors Corp.'s Chevrolet Volt - in which, by design, the driver ideally isn't connected to its small internal-combustion engine - make a case for being vehicles that have much to do with engines. So now the industry's marketers, advertisers and other communicators also might be scrambling to figure out how best to address age-old definitions that are rapidly changing or just don't apply anymore.
The Ward's 10 Best Engines list, now in its 17th year, hasn't turned into an victory of electrons over hydrocarbons just yet: the other eight of this year's winners are mostly performance plays - there are two V-8s and the five or the remaining six internal-combustion engines are either turbocharged or supercharged, and you know what that usually means.

Smoldering? Really? I'm pretty sure it makes quite a good flame. Smoking, in the figurative sense, maybe?
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 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 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.
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.
