The technology provides water injection to all IC Engines, compression ignition of
gasoline engines and conversion of diesel engines to gasoline to reduce fuel
consumption, global warming and pollution.
Part A. Technical information.
i. Loss of energy in all IC Engines.
More than a billion IC Engines are working in services like cars, buses, trucks, rail
transport engines, very heavy diesel engines, stationary diesel engines and IC
Engines driving heavy cruises and in scores of other services. In case of all IC
Engines including gasoline driven engines, around 60% of energy provided by fuel
is lost to cooling water resulting in poor efficiency of around 20%. Gasoline driven
engines have added disadvantage of pre-ignition which further reduces performance
of gasoline driven engines. Considering that more than a billion IC Engines are
working throughout the world, IC Engines are contributing maximum to pollution
and global warming and loss of energy. Manufacturers of IC Engines including
leading manufacturers of automobiles have not addressed the problem. This
innovation for the first time addresses the problem to reduce fuel consumption by
water injection after combustion to all IC Engines and by injecting gasoline after
compression. Water/gasoline injecting pumps are developed for this purpose.

ii. Prior art water injecting systems.
iia. Water injection to suction manifold of IC Engines at low pressure.
Water injection is in vogue for over a century. Fighter planes in Second World War
were provided with water injection to suction manifold. The concept was mainly to
inject water to suction manifold in the form of a spray at around 300 psi. Gain in
additional distance covered was meager 3 miles per gallon in case of cars. The
system calls for additional wiring, control valves, solenoids etc. Cost of conversion did
not justify meager benefit and hence the system is not used even in running
automobiles.
iib. Trials by injecting water directly to combustion chamber of an IC Engine.
Trials were conducted by injecting water directly to combustion chamber of an engine driving
a car. Increase in distance covered was 20% to 40% and increase in power 10 % to 15%,
reduction of emission from 20% to 60%. Apparently water was injected at random instead of
after combustion and hence results were not consistent. As a result, this prior art system is
not to be found in running automobiles. By clicking on image on slide 8, Video clip can be
seen.
this innovation.
This innovation is improvement over prior art experiment mentioned above wherein
water is timed for injection just after combustion by synchronizing movement of pistons
of pump with that of engine. The innovation is based on established engineering
practices. Hence, this innovation is feasible and practical. Observation of leading
manufacturers of automobiles from Japan and USA shows feasibility of water injection
after combustion.
iv. Reviews.
iva. Idea 2 Business 2016 organized by Amity Business School have conferred ‘Best
Idea Award 2016’ for the innovation.

Dear Mr. Reddy,
Thank you for sending your proposal for Port Water Injection for enhancing
performance. We have gone through you proposal and it is good to see the effort put in
detailing the idea envisaged
REDUCTION OF FUEL CONSUMPTION IN ALL IC ENGINES. 4
REDUCTION OF FUEL CONSUMPTION IN ALL IC ENGINES.
Continued: In the past lot of work has happened in Port injection of water to prove
the technology, however in your innovation, the injection is done just after
combustion, which seems to be a unique feature. In our opinion, before this
technology is tried in passenger cars, it would be good if the same is proved in
stationary application or at standalone engine.
Moreover, currently we are not working on this technology front and hence, are not able
to dedicate any resource for investigating the technology proposed by you.
We appreciate your work and wish you all the best for carrying your work further.
Best Regards,
P. Panda
VP (Engineering),
Maruti Suzuki India Limited.

Dear K.N.S.,
Thank you for submitting an idea to Ford Motor Company. Your suggestion was forwarded
to a technical specialist for evaluation. Their evaluation is based on two major elements:
1) improvement upon current technology, and 2) cost. Our technical specialists have
reviewed your idea and concluded that Ford Motor Company will not be able to further
investigate development of your particular idea, nor acquiring any rights on your behalf.
Water injection and compression ignition are well-known technologies. Ford produces
compression ignition engines for many market segments, but spark ignition engines offer
advantages in other market segments. Water injection has been used in piston engines for
aircraft and it is well known to adapt automotive engines for this. However, Ford is not
interested in using this currently for production engines.
Regretting that our response could not be more favourable, we, nevertheless, thank you for
your interest in Ford.
Regards.
Consumer Innovation Office.

v. Improving performance of IC Engines.
Performance of IC Engines can be improved by: i. Synchronized water injection after
combustion. ii. By compression ignition of gasoline engines. iii. By combined compression
ignition of gasoline engines followed by water injection. Water/gasoline injection pumps
are developed for this purpose.
