Abstract

The Eco 1 Hydrogen Engine has a cylindrical stator and a saw tooth shaped rotor, defining wedge shaped chambers between the rotor and stator. There is at least one combustion chamber with fuel inlet K and spark plug J, and corresponding outlets V. The engine is fuelled by Hydrogen gas from an electrolyser. The engine may provide part of the energy required by the electrolyser.

ECO 1 HYDROGEN GAS ENGINE

Environmentally Friendly Engine

Introduction

I will assume for the purpose of a simple explanation that the dimensions for the cell rotor Wheel inner diameter is lMtr this will give a Circumference of 3.147 metres. There are 48 cells around the circumference.

The Height of each cell is 25mm angled from top right to bottom left... Variable.

The Length of each cell is equal to 360 degrees divided by 48 = 7.5degrees or 65.255mm. Variable. The Width of each cell is around 75mm tapered in towards the centre from both sides. Variable. This means that each cell capacity is = 122.35312cc X 48 cells = 9497cc or a 9.51tr engine approx. That runs on a very cheap fuel. But with more power and energy than a four stroke petrol or diesel engine of 151trs.

The measurements at this stage are all variable. As we do not know the maximum efficiency size that will give the ultimate performance for the size of each engine. This can only be achieved when we have a working engine that will prove out under test conditions. As this is a new design of rotary combustion engine then maths at present will not give any accurate results. We all know that hydrogen gas has been around or over 70 years or more. But this type of engine will have been around for a few seconds once it is built.. As we know there are a number of factors to take into consideration. Such as the amount of gas to create the required bang. The size of bang. Its power ratio. The temperature generated. Its dispersion rate. Thrust and pressure. Then the speed or rotation and load it can move in a certain time. The cost of the hydrogen gas is not considered as a part of the equation as it is virtually free. Except for the amount that is generated by the electrolyser should be adequate to run the engine whatever its size. With a percentage of extra gas for the purpose of storage cylinders.

NB

Do not take any notice of the dimensions of the chassis thicknesses as they are all variable. The distance between the fuel input injector pipe and the spark plug has to be at least 2 degrees, but as it is in the same chamber then as long as the spark is executed within the chamber at all speeds it. Should be alright.

ECO 1 HYDROGEN GAS ENGINE

Environmentally Friendly Engine

Planning for tomorrow keeping yesterday in mind

Description

A. Main Engine Outer Casing

The outer engine casing protects all the parts within the engine in case of damage Alternative Engine bonding method

If each single rotary engine can have up to 3 combustion chambers, with one spark plug each.

Where each chamber can be turned on or off as required, and from one to three cams. This will give it a maximum power output ratio of a six-cylinder engine in one. Thus reducing the resistance and inefficiency that is gained in a normal four-stroke engine of greater size. For the same power output. These will be supplied with the normal fuel injection system. Except the BTDC will be reduced from 5 degrees down to 2 degrees, this makes the engine run quieter and with less wear and tare on the moving parts and more efficiency.

Instead of having three separate engines. It would be more efficient to bond them together as per diagram. This way one gains the benefit of full power using less space.

B. Engine Housing

The Engine Housing on this drawing is rectangular for efficiency of fixing, storage and moving. Fixed and attached to the engine are the meters and gauges for monitoring purposes. Plus the Hydrogen Gas pipes and ignition wiring etc

The ignition cams on the outside of the rotary cell wheel may be operated by the conventional cam point switch, or to lower the drag and resistance it could use a laser light type reflector cam or even a magnetic type there would be one up to a max of two per engine and a max of three combustion chambers.

I have at present used two for simplicity and the exhaust vents would also be in accordance to the number of chambers. Or there may be just one per engine if the engines are banked together.

C. Water Cooled Casing

This is a normal way of cool during it operation, so as the engine does not overheat..

D. Rotor and Cells

The Rotor and cells are the main moving section of the engine as this where energy from the combustion chamber is converted into rotational movement. The Cooling fan is an integral part of the rotary action of the moving engine. It helps to keep the engine cooler by inducting a draught that passes through all of the inline engines when they are stacked together. Or as an individual cooling system on lone standing engines.

E. Air Cooling Space

This is the air space between the outer casing and the flat generator it is there to help keep the generator cool during operation.

F. Flat Magneto Generator

The combustion chamber is positioned at an easily accessible place on the engine. The Ecol Gas Engine is built to run on Hydrogen Gas. It is also a new and unique engine design. There is less friction and resistance in the Eco 1 Hydrogen Gas Engine than in the conventional four-stroke petrol or diesel engines. The Ecol hydrogen Gas Engine is in advance of any other in use at present. The Eco 1 Hydrogen Gas Engine runs on Hydrogen Gas. It is virtually self-sustaining the gas supply pipes feed the fuel to the engine. It can provide power from its own built in generator. It does not need a separate power supply for its electrical system. It may require an extra external generator to sustain the need of the electrolyser.

G. Fan Blades

The fan Blades have two functions one is to help keep the engine cooler and the other is to expedite the exhaust fumes out of the rotary cells.

H. Connection Rods

Connect the rotary wheel cells to the Axle or Drive shaft

I. Drive Shaft

The Drive Shaft is the main component that takes the power from the engine to the desired output attachment, whether it is a ships propeller or power generator. If the engines were attached side by side, a spine fixing from drive shaft to drive shaft would connect them.

J. Expansion Chamber

This has the main function of driving the engine in a rotational direction as the gas is expanding in the combustion chamber. It may cover several cells in the process.

K Combustion Chamber

Now unlike normal engines there may be more than one combustion chamber per engine. By adding two combustion chambers would be the equivalent of that of a six cylinder engine.

L. Fuel injector & Valve

It allows a quantity fuel to enter the engine at a specified time.

M. Spark Plug

It sparks. The spark plug is the final stage after which the gas has entered the combustion chamber prior to being ignited. Now the spark is supplied via an ignition coil and will get its power supply form the inbuilt generator. This format will supply as many engines that are in use.

N. Seals-

There are three seals on either side of the engine. They are there to prevent gas that is under pressure from escaping from the rotating expansion chamber so that the performance is not reduced, and the combustion pressure is kept to a maximum.

P. Exhaust Pipe

The exhaust pipe is there simply to allow spent gases to exit from the rotary cells this allows the new explosion within the combustion chamber.

Q. Bearings

Very simply these are to assure a smooth operation of the rotation of the rotary wheel. R. Rotor

This is the moving section of the power generator that generates power to run the engine and some ancillary components

3

S. Stator

This is the fixed part of the Generator also where all the connections and wiring goes to other components

T. Exhaust Open Canopy

This is basically a quarter framework that the exhaust pipes are attached to, they enhance the expelling of the exhaust fumes. A complete canopy may be installed if it is necessary.

U. Positive Power Leads

These power leads are an extra source of power that can either run the engine and some of its ancillary components, or it can be diverted to the electrolyser as a booster generator. The negative is earthed on the chassis of the vehicle

The Ecol Hydrogen Gas Engine. It comprises of a direct rotational multi-cylinder drive. Its fuel is Hydrogen Gas extracted from water via an electrolyser or it may use a fuel cell.. It is new and very unique engine design. For it generates its own power from a built in generator that is attached to the rotary arms of the support members as it turns on its drive shaft.

There is less friction and resistance in the Eco 1 Hydrogen Gas Engine than in the conventional four stroke petrol or diesel and other gas type engines. It has higher revolutions per minute that any conventional four-stroke or two-stroke engine. It needs a fuel source to run just like or any other conventional fuel system. Except this is using H2.

The Eco 1 Hydrogen Gas Engine is in advance of any other in use at present. There are no toxic fumes expelled from the exhaust that can pollute the atmosphere. So it is environmentally friendly.

It may have more that one combustion chamber to give greater power as per drawing or as required The configuration can be complex or simple. It is not perpetual motion as it is dependant on fuel. It works in a similar method to the other fossil liquid fuel or gas based engines.

There is a built in fuel switch over valve that allows the driver or controller to change over from hydrogen gas to a conventional fuel supply. It may also carry a spare hydrogen gas tank, so if it runs low on the supply it may be changed over to the spare cylinder.

The out put of the electrolyser is determined by the consumption rate of the engine and then doubled to enable it to supply the working engine and the spare Cylinder that will also supply the electrolyser drive engine.

As for the initial supply the power can be gained from other power generators. Such as wind power, solar power or water power. Keeping in mind that the power pack will always be there to enable the engine to be started initially and supply the required power this is also constantly charged as the engine is working.

Or it may be charged by an independent battery charger.

Each engine can be banked or stacked either together or separately to give as much power that is required that matches the size of engine or the size of generator. It comes in many different sizes to suit application requirements.

There are many ways of explaining how the Eco 1 Engine works but I have tried to keep it to a basic description. The components that are pre-engine are already available on the market. Though I have shown them in the flow diagram to give a simpler understanding. See description and drawings for a fuller explanation.
