Abstract

A compressed air and combustion engine combination engine has alternate 4 stroke combustion cycles and 2 stroke compressed air cycles, making an overall six stroke cycle which creates additional power. The compressed air is best achieved from the otherwise wasted heat energy from the exhaust system to raise steam which drives a turbine-driven air compressor. This system is complemented with additional methods of creating the compressed air when the vehicle is cold through the use of the engine's power output to drive an air compressor that cuts in once the vehicle is moving above a certain speed, compressing the air into the tanks for use in the 6 stroke cycle. The compressed air may alternatively be obtained using an outside energy source, eg at a service station or the overnight use of an electrically driven compressor. If the tanks were low the compressed air would be used to drive the 6 stoke cycle only under the heavy engine loads when the combustion engine is least efficient. The compressed air is captured in cylinders / tanks or the framework of the vehicle which is then used in the 6 stroke cycle to create additional power strokes which in turn increase the efficiency of the engine and produce no harmful emissions.

Air Six Shooter -Description
This invention relates to the creation of a combination engine that uses a combustion engine and Compressed Air in alternation within a combustion engine to produce power.
The invention uses a 6 stroke engine cycle adding a renewable energy source power stroke and exhaust stroke to the standard 4 stroke cycle. After the traditional exhaust stroke and before the traditional induction stroke an additional power stroke is created using compressed pressurised air injected into the cylinders pushing the piston down then on the up stroke the environmentally friendly air is pushed out the exhaust ready for the standard combustion engine fuel induction stroke. The compressed air could be created through the use of currently wasted heat energy created by a combustion engine.
The problem tackled by this invention is one of making combustion engines more efficient without producing further harmful emissions.
The primary object of the invention is to provide a method of making combustion engines more efficient in their use of fuel. The secondary objective is to achieve this without producing additional pollutants. Third objective is to achieve this with minimal change to the existing engines design.
The solution applied makes use of the currently wasted heat energy within a combustion engine which currently is radiated away from the engine and is lost to the atmosphere.
The combination engine simply adds a two stroke cycle of compressed Air onto a 4 stroke engine cycle resulting in a six stroke engine.
Compressed Air There are several methods of creating the compressed air but all of them would create compressed air stored in tanks / cylinders or possible the frame of the vehicle. These then can be used to release a shot of compressed air into the cylinder at the appropriate time creating a air driven power stroke in the 6 stroke cycle.
Option 1 -Compressor pump of the standard engine At speeds where the engine is efficient and not labouring, which in most vehicles is above 40 miles an hour most vehicles economy starts to move rapidly towards the engines optimum efficiency so at this point the engine could be used to drive an additional compression pump system which engaged to charge up several air tanks then disengage again. The compressed air in the tanks can then be used within the six shooter engine cycle at the points when the standard engine is least efficient such as pulling away and accelerating. This would greatly reduce the fuel use of the engine at the lower speeds which would have the effect of pulling the overall engine fuel economy up. This option assumes a part time 6 shooter approach that the 6 shooter is only used when the normal combustion engine is least efficient.
Option 2 -Home or Garage plug in to Electrical compressor to charge tanks This option uses the compressed air tanks in the same way as a battery which can be charged either through an electrical compressor at your house or at a garage which provides compressed air into the tanks. In this approach once the tanks are empty the vehicle would ran as a standard engine until the tanks could be re-charged.
The compressed air in the tanks can then be used within the six shooter engine cycle at the points when the standard engine is least efficient such as pulling away and accelerating. This would greatly reduce the fuel use of the engine at the lower speeds which would have the effect of pulling the overall engine fuel economy up. This option assumes a part time 6 shooter approach that the 6 shooter is only used when the normal combustion engine is least efficient.
Option 3 -Wasted energy charging of compressed air tanks This option uses some of the currently wasted energy from the fossil fuel engine to compress the air. This option would use the heat of the exhaust gasses to heat water to the level that is converted to steam and the steam would be directed through a turbine which would compress the air for the tanks. This approach once the vehicle is warm would through the use of several tanks (at least one being charged and one being used in the six shooter engine cycle) enable the 6 shooter approach to be used continually which would have the maximum fuel efficiency benefits. Additionally if option I or 2 or combination of both is used before the vehicle is warm the engine could run as a six shooter all the time.
Option 4 -Braking energy conversion to compressed air tanks This option uses the vehicles braking to create compressed air to charge the tanks. This option would work with a compressor at each wheel centre that is engaged at the point of braking using the spinning motion of the wheels to drive the compressor and charge the tanks. This option would have to be combined with one of the above options to create sufficient compressed air to drive the vehicle continually in the six shooter approach.
A preferred embodiment of the invention will now be described with reference to the accompanying drawing in which Fig I step I -shows the traditional compression stroke of a Fossil fuel engine Fig 1 step 2 -shows the traditional power stroke of a Fossil fuel engine Fig I step 3 -shows the traditional exhaust stroke of a Fossil fuel engine Fig I step 4 -shows the new compressed air shoot into the cylinder creating an additional power stroke.
Fig I step 5 -shows the new compressed air exhaust stroke Fig I step 6 -shows the traditional induction stroke which injects Fossil fuel into the cylinder before going back to Fig I step I -compression stroke.
As shown in Fig I step I a traditional compression up stroke of the piston which would have the inlet valves and exhaust valves closed.
As shown in Fig I step 2 this is followed by a traditional power down stroke of the piston through the explosion of the fossil fuel.
As shown in Fig I step 3 this is followed by a traditional exhaust up stroke of the piston pushing the spent fossil fuel gasses out of the exhaust valves.
As shown in Fig I step 4 this is followed by a new compressed air shoot into the cylinder creating an additional power stroke without use of fossil fuels.
As shown in Fig I step 5 this is followed by a new compressed air exhaust stroke with the exhaust valves open.
As shown in Fig I step 6 this is followed by a traditional induction stroke which injects Fossil fuel into the cylinder before going back to Fig I step 1.
Repeated Two stroke air shooter As shown in Fig 2 if enough compressed air is stored within the cylinders / tanks it would be possible to run the engine on compressed air 2 stoke shots repeatedly around town to reduce the fuel consumption in the areas that combustion engines are both inefficient and also pollutants of the populated areas.
The preferred embodiment of the compression of the air for the compressed air tanks is Combination of Option 1 and 3 -Compressor pump of the standard enging and Wasted energy charging of compressed air tanks This option uses power from the existing combustion engine when the vehicle is cold and swaps to use the currently wasted heat energy from the engine to compress the air when the engine is warm. This option would use the heat of the exhaust gasses to heat water to the a level that it creates steam and the steam would be directed through a turbine which would compress the air for the tanks. This approach once the vehicle is warm would through the use of several tanks (at least one being charged and one being used in the six shooter engine cycle) enable the 6 shooter approach to be used continually which would have the maximum fuel efficiency benefits. Additionally until the engine was hot Option -"Compressor pump of the standard engine" would be used. At speeds higher than 35-miles an hour most vehicles economy starts to move rapidly towards the engines optimum efficiency so at this point the engine could be used to drive an additional compression pump system which engaged to charge up several air tanks then disengage again. The compressed air in the tanks can then be used within the six shooter engine cycle or repeated two stoke compressed air cycle (fig 2) (if sufficient compressed air available) at the points when the standard engine is least efficient such as around town, pulling away and accelerating.
