Description

Fuel Saving Device and Method of reduction of fuel.

This invention relates to a kit having electronic components, hardware and software to improve the fuel economy of vehicles. This invention aims to reduce the polluting exhaust gases by less usage of fossil fuel in the vehicles. An advanced apparatus and method for breaking normal water into its components by method of electrolysis and vibronics having advanced hydrogen on demand system kit is disclosed. The invention operates at low voltage and current. The production of the gas as fuel is regulated and is controlled during production, which is then used along with the air intake manifold of the vehicle engine to reduce fossil fuel consumption.

Background of the invention

Across the world the Climate Change is a major problem. It is not a secret that transports vehicles and mobility contributes to a huge portion of the green house effect. Daily the exhaust of the present transport system is a threat to human lives, which creates pollution related diseases across the globe today. Reduction in use of oil/fossil fuel would reduce the problem of green house. Alternate fuels would help save the current and next generations.

We are at the cusp of a revolution to change the way we interact with our world. We have polluted the world by the excessive use of oil and oil based products. One of the largest contributors to global warming is hydrocarbon fuel and we urgently need an alternative. Energy from sun, wind and tides are available but will not be sufficient quickly enough for our dependence on oil to be cut drastically. We have the technology and we need to implement.

The electric vehicles have inherent challenges of charging and range of the distance covered. The cost of battery has been always making it uneconomical. It requires huge infrastructure to compete and promote the usage. Also, the present ways to make electricity is also as polluting as the usage of fossil fuel medium. The only difference being one is centralized to a location as a power plant and the other being used in moving machines as combustion engines to produce the green house gases. The production of electricity from wind and sun is also in a nascent stage having its own limitation and implementation challenges.

The present invention i.e. the Advanced Hydrogen On Demand System (AHODS) will act as a disruptive way to convert the millions of cars and automobiles across the globe to reduce the consumption of fossil fuel and will provide better environment for the future. The effect is humungous and phenomenal which could remove the air pollution in many cities of the world.

Detailed description of the preferred embodiments with reference to the accompanying drawings.

The development of AHODS technology since many years being in Automotive industry. The initial attempts & effort consisted of sifting through the huge amount of information available on the internet to try and separate the kernels of genuine information from the number of tall claims which are so prevalent about anything on the internet. Thereafter, more specific studies were conducted with the object of deciding on a basic design for eventual fabrication and testing. Over a period of time, with a clearer understanding of the tasks involved, the technology was divided into the following different sections, which were then pursued concurrently:

^¨ Basic concept and design

^• Building Prototypes

* Trials and testing

« Freeze the eoneept

• Continuous improvements

The Kit as per BOM is applicable to all the 1C engines either stationary eg. the DGs and moving ones on vehicles for mobility . Vehicle includes all the passenger and commercial vehciles including train engines including boats and small ships. Application can also be on the water ways on boats , speed boats , cruise ships and carrier ships. Also a major application is for the DG engines industry.

A successful AHOD kit consists of the following parts. It has been explained in a block diagram showing the regular vehicle components and parts along with the additional parts which needs to be added for augmentation of hydrogen into l/c engine.

1. AHOD Generator:

a. AHOD Cell Pack: An efficient electrolyzer, w h i ch generates sufficient HHO gas at the lowest possible current drawn from the car’s (or generator’s) alternator. The construction is strong and rugged enough to withstand the work environment, yet easily accessible and serviceable. This has steel plate / mesh configurations of SS316L as shown in Figure 5. The configuration of number of plates depends on the volume of gas required for a particular capacity (cc) of engine and fuel type (Gasoline/Petrol or Diesel). There could be a pipe configurations and others as well depending on the gas volume requirement and size requirements. b. A DC Pulse Circuit: This is a vibronic circuit generating resonance a nd is used to break water into hydrogen and oxygen as HHO gas. The basis of the current, fre q u e n cy , voltage combination is as per the equation shown in Fig. 12. Th is circuit in combination with the the AHOD Generator(a) is a unique and novel. The circuit is a combination of Resistors .Gapaeitors, Transistors, 1C & MOSFETS etc. This enables pulses to AHOD generator enhancing the electrolysis at lower currents. When the water is electrolyzed along with hydrogen and oxygen even He3 is produced. c. Electrolyte: The best suited electrolyte has been found to be KOH with additives. This enhances the volume of gas production. d. Solenoid Valve (SV): A solenoid vaj e is provided to cut off and control the gas circuit.

e. Pressure Release Value (PRV): The pressure release valve is a safety valve to open in case of malfunction or high gas pressure due to any reasons. It open up to release HHO gas into the atmosphere which finally converts to Hydrogen and Oxygen. This is installed¹ on the gas circuit.

f. Flash Back Arrestor. This is installed in the gas circuit. It has a

_> safety function to stop any back flash/spark from Engine Manifold or any malfunction in rare case to the AHOD Generator. g. Standard Fittings, connectors and piping are required for the same. h. An optional scrubbing system to ensure the complete removal of the electrolyte (in case used) from the gas before it enters the intake manifold of the engine.

2. Electronic Fuel Enhancer Circuit: A suitable electronic system to work in conjunction with the car’s computer (the ECU) to ensure that the ECM does not override the new combustion environment created by changing the fuel from hydrocarbon alone to hydrocarbon + HHO. A suitable constant current pulse width modulator (CCPWM) ensures that the gas production remains exactly at the level set for the particular engine on- which the kit is installed.

3. Bluetooth EOBD: This is an interface between the vehicle diagnostic data and the mobile phone application. EOBD collects the relevant data from the Engine ECU and sensors and then the data is send to a synchronized smart mobile phone. This data is further used by the phone application for analysis, display and reports. Fig. 7

4. Mobile Application: A Phone Application working on android and iOS for the display and monitoring along with vehicle data acquisition, display, analysis and reports. Fig. 11

5. In-car LED Display and Control: Suitable display system which shows the driver or generator operator that the system is working fine. The switch is used to activate or deactivate the AHOD System. This brings flexibility and convenience to the driver to run as normal with Gasoline/Diesel or with AHOD Kit. Fig. 10

6. A safety system which ensures that HHO is vented outside the car in case of any malfunction.

a. There is a solenoid valve to cut off supply of gas as soon as the vehicle is stopped. It only allows the flow when the gas is in use.

b. The pressure safety release valve is put between the manifold and the generator cell. In case of any malfunction or rise in the gas pressure, it diffuses the gas to the atmosphere.

c. The flash back arrestor-: In case of any malfunction or back pressure.

The flash is arrested in FBA by reducing the pressure and submerging in fire retardant material like asbestos powder / sand etc.

7. There are plumbing connections for flow of gas and water in and out of the generator.

8. A wiring Harness for connection on the vehicle with existing auto electrical and electronics

The first electrolyzer consisted of a plastic jar filled with water with some form of tube or plate electrodes, with its obvious drawbacks. This design evolved over many iterations into the present day 'dry-cell’, which is now considered to be the best and most rugged design for automobiles and generators.

The design of the electrolyzer is depicted in Fig. 5. The plates are made the plates are of SS 316L, with rugged container and the gaskets are silicone rubber. This is mounted under the bonnet at a suitable place. A water bottle/container is also installed and connected to the AHOD Cell . The level of the water container /bottle has to be above the Generator cell.

The EFIE circuit box is located under the bonnet with the wiring harness laid down connected to various sensor inputs. The in-car unit is mounted near the steering wheel at the dashboard for easy access , visually as well as for switching ON/OFF of the AHODS. The Bluetooth OBD-II is plugged in the OBD port of the vehicle, which is generally under the Dashboard.

The complete block diagram representing the complete connection of the AHODS with vehicle components is provided in the Figure 4. Installation AHQR System;

1. AHOD System: Physical connection and installation of the kit is done based on the vehicle configuration, the space available under the bonnet in the vehicle and the mounting possibilities. The generator is mounted on the brackets to the body. The water bottle and other parts are also mounted on the car body under the bonnet or at a suitable place as per the service manual of the car.

The wiring harness is connected with battery, the generator, the solenoid valve, and the EFIE as well as In-car control circuit boxes with switch ON/OFF. All the water piping, gas piping is routed and laid down properly. The wiring harness and other electronic connections are done properly with no loose connections. The Bluetooth OBD- II is connected to the port on the car. The phone application is installed on the mobile phone of the driver. The detailed installation procedures can be provided in the manual that would cover the details during the mass usage.

2. Vehicle Tuning; The tuning process can be broken down into the following steps. The tuned AHODS system is done as per the engine size, type and vehicle variant depending on the fuel used. The tuning is done with the help of electronic adjustments as in the vehicle ECU uses the following inputs: MAP (Manifold Absolute Pressure), TPS, MAF (Mass Air Flow), ECT (Engine Coolant Temperature), IAT (Intake Air Temperature), and 02 (oxygen) sensors, apart from several others.

a. Lowering lean-out limits: The lean out limits are reached with the help of adjustment on IAT sensors, CTS, MAP sensor inputs.

b. Adjusting Air-Fuel mixture: The ECU seems to always get that there is a rich mixture of Air-Fuel with EFIE using 02 sensors etc. c. Adjusting ignition timing: The key to getting sustained mileage gains revolves around the adjustment of ignition timing. Two modifications carried out effect the timing:

i. Increase in AIT temperature causes the ECU to retard the timing.

ii. The MAP modification advances the timing.

The gas so produced, is controlled by using a solenoid valve. A pressure release valve is used as a safety valve and is operated in case of high gas pressure or any malfunction. A flash back arrestor is also used to stops any flash/ spark from engine manifold or from AHOD generator itself; connecting pipes which take the gas produced to the engine manifold. Optionally, a scrubbing^‘ system is used for complete removal of the electrolyte from gas before entering the engine manifold. The gas so generated through the device is fed into the engine along with the air intake manifold of the vehicle engine to reduce fossil fuel consumption. Working examples;

The kit was first tested on a popular car model with a 1 .3 liter petrol engine. During the course of the testing, several electronic system settings were tried which culminated in the final test which showed petrol savings to be approximately 40%, and reduction in emissions to be approximately 80%. Before the tests were carried out, a complete manual was created to give the steps which need to be followed to successfully save fuel and reduce remissions in the internal combustion engine. The complete installation and tuning procedure for petrol & diesel engines have been established.

The present invention seeks to overcome the shortcomings of the prior art by. providing new technologies in areas such as converting water into a usable fuel with a combination of components and sub systems.
