Description

Method and Equipment for Utilization of Energy Released through Vehicle Movement
Technical Field
The invention concerns increase of operation economy of motor powered and towed vehicles, namely both road vehicles, for example cars of all types, tractors, agricultural, forest and other self-propelled machines, and rail vehicles, furthermore ships, aircrafts and all military engine self-propelled machinery. The invention solves method and equipment for utilization of energy released through vehicle movement, whereas there are utilized both gravitational energy released at vertical movement vehicle or of its parts, and kinetic energy released when braking.
Description of Prior Art
It is known that vertical movements of the whole vehicle and also of its particular parts occur during vehicle travel through movement on bumpiness. Energy of these movements converts into thermal energy, most frequently in springs, suspension springs and in shock absorbers. This energy is not utilised in no manner. Furthermore, it is known that vehicle's kinetic energy converts in brakes while vehicle braking into thermal energy, which is utilised in no manner, too. Furthermore, it is known that through coupling electric generator with a rotating vehicle part while braking there can be got electric energy that is used for charging accumulators consequently. These accumulators can be subsequently used both for electric motor drive of auxiliary vehicle devices and as an auxiliary power supply for ensuring vehicle drive. Disadvantage of such equipment is a high weight of accumulators that increase the vehicle weight and so increase the haulage weight unnecessarily. The further disadvantage is difficult observance of optimum conditions while braking. The further possibility is utilization of obtained electric energy for water decomposition into hydrogen and oxygen that are used as an in ratio adapted mixture for vehicle drive subsequently.
Disadvantage of this solution is a relatively low speed of the electrolytic process, which is associated with that the electrolytic device of required output is considerably large and demanding with regard to construction of a combustion engine that has to be able to burn both hydrogen and petroleum fuel in various ratios, and furthermore, the vehicle has to be equipped with a water tank that increases vehicle's haulage dead weight unnecessarily.
Disclosure of Invention
The stated disadvantages are solved through the method and equipment for utilization of energy released in vehicle operation according to the invention. The method principle is that mechanical energy of linear and/or rotational movement of at least one vehicle part converts through braking and/or force of gravity to pressure energy of compressed air, which further accumulates, whereupon the pressure energy of compressed air converts to mechanical energy and/or the compressed air is led into a combustion engine for its drive or for output increase. Alternatively, the principle is that air pressure energy converts into mechanical energy ensuring and/or supporting vehicle's driving movement and/or vehicle's moving off. Alternatively, the principle also is that the compressed air is led into an air intake manifold of a combustion engine and/or into a turbocharger. According to further alternative, the principle is that the compressed air is led into a linear or rotary air engine, which is vehicle's combustion engine and/or an engine driving auxiliary vehicle devices. Alternatively, the principle also is that the compressed air is warmed up through lost heat released by a combustion engine.
The principle of the equipment according to the invention is that it consists of an air compression device, of an accumulation tank and of a compressed air utilization device. The air compression device is coupled with at least one vehicle's part and is provided with an air inlet from ambient atmosphere and with compressed air outlet. The compressed air utilization device is provided with a compressed air inlet and the accumulation tank is connected through at least one closable fitting to the compressed air outlet of the air compression device and/or to the compressed air inlet of the compressed air utilization device. Alternatively, the air compression device is at least one compressible bellows situated between two mutually moving vehicle's parts or at least one piston type compressor that consists of at least one air cylinder in that a sliding compressor piston is situated, whereas the air cylinder is connected with another vehicle's part than the compressor piston. Advantageously, at least one part of the compressible bellows or of the piston type compressor is coupled with a vehicle's part by means of a pivot and/or a joint and/or a linkage mechanism. Alternatively, the air compression device is repeatedly attachable to a vehicle's part that is rotary, whereas the air compression device consists of at least one auxiliary compressor and/or turbine. According to further alternative, the air compression device consists of a camshaft, on which a cam is situated, whereas the camshaft is permanently attached or repeatedly attachable to a vehicle's part that is rotary, whereas the cam working surface is in contact with at least one piston type compressor consisting of at least one air cylinder in that a sliding compressor piston is adapted. According to the further alternative, the piston type compressor is provided with at least one device for prevention of its contact with the cam, advantageously through equipment for fixation of the compressor piston in top dead centre. According to the further alternative, the air compression device is a combustion engine with closed fuel supply, the air intake manifold and/or exhaust manifold of which is a compressed air outlet of the air compression device. An alternative is also when the combustion engine is provided with at least one device for opening of the intake valve at expansion and of the exhaust valve at compression. The compressed air utilization device is a combustion engine connected to fuel supply, whereas the accumulation tank is connected to the air intake manifold and/or to the second inlet of the turbocharger, which is installed in the air intake manifold, where the first turbocharger inlet is opened into ambient atmosphere. Alternatively, the compressed air utilization device is a combustion engine with closed fuel supply, the air intake manifold and/or exhaust manifold of which is a compressed air inlet of the compressed air utilization device. The combustion engine is provided with at least one device for opening of the intake valve at expansion and of the exhaust valve at compression. According to further alternative the compressed air utilization device is a turbine and/or an air engine for drive of auxiliary devices and/or for braking system. Advantage of the method and equipment according to the invention is that a great saving of fuel is reached, because up to 50% of otherwise foiled energy is reused. The energy released in the course of braking or stopping vehicle is comparable to the energy required for moving off or acceleration. Its share in overall energy consumption is dependent on style of driving, and in unfavourable situation, for example when driving through city or when driving in undulated relief, it can reach up to 50% of overall energy consumed for operation. The energy released through vehicle movement is got, accumulated and utilised at minimum dead vehicle weight increase. The equipment is reliable, it works in wide spread of conditions, it requires no fulfilment of specific technical requirements and no addition of further compounds needed for operation, for example water for electrolysis into hydrogen and oxygen.
