The arrangement according to claim 12, wherein the volume change chambers have successively increasing or decreasing volumes. The diagram gives a good visual comparison of work done between the various processes. The main mechanism consists of easily recognisable main parts such as a cylinder assembly 100, a piston assembly 110 with seals 113 and a piston stem 114, an adapter 115 with a bearing functioning as an interface between the piston stem 114 and a connecting rod 116, a crankshaft 117, bypass and outlet valves 122, 131 with valve actuators 123, 132, shown here as cam shafts, a bypass line 121, a thermally insulating seal 140, hereinafter also called a thermo-seal, and also other common components and designs such as bolts, threaded holes, bearings, seals, lubricating channels et cetera that a person skilled in the art will find necessary for the construction. The valve may also be adjustable in accordance with known control principles to allow the flow rate and the pressure of the working fluid flowing out of the heating course to be adjusted according to various needs. In such an example the first expansion process taking place in the first chamber will have the character of a polytropic or a mixed polytropic expansion, where a considerable amount of heat is supplied provided the heat exchanger is suitably designed. When all the fluid is displaced out of the cylinder and into the cooling course, the heat engine outlet valve is again closed, and the fluid, now nearly completely displaced into the cooling course, may be cooled further at constant volume.

What is your motivation to participate in the DryF project and develop new components for increasing energy efficiency in industry? The engine is further characterised in that the first cylinder chamber functions as a heat exchanger toward the working fluid so that heat may be transferred through the cylinder wall from a thermo-fluid in an outer fluid course and into the working fluid in the chamber, so that extra heat may be fed to the working fluid in the expansion process to thereby achieve an increased effect through-flow in the engine. If you would like to join our team, The idea behind Viking Development Group is to offer engineers and inventors a flexible and inspiring creative environment in which they can develop their innovative ideas into patented products and systems. Q in2 represents the heat supplied in the first non-adiabatic, alternatively polytropic expansion process process 3 in the cycle , wherein heat is transferred to the working fluid in a first cylinder chamber 150 from the heat exchanger of a lower cylinder 102 alternatively from the heat exchanger of a first cylinder 100 a for a two-cylinder variant. In a single-cylinder embodiment, after finished expansion in the second cylinder chamber, nearly the whole amount of working fluid will have been moved from the first cylinder chamber to the second cylinder chamber. For there always to be sufficient working fluid available for the process, the liquid tank 5 is arranged at the outlet of the cooling course 4, and a surplus of working fluid may flow in and out here as needed.

In the thermodynamic cycle and heat engine that this invention deals with, a characteristic composition of sequential thermodynamic processes is provided. The top cylinder 101 may be made of various materials, both metallic and non-metallic. Step 2 constitutes further heat supply from at least one recuperator 32, 35 and at least one heater 33, respectively, in the system. In a case where no thermo-fluid is circulated, and therefore no heat is supplied to the working fluid, a near-adiabatic expansion process may be achieved provided the expansion occurs quickly enough. The method according to claim 2, wherein the fourth process further involves supplying further heat to the whole or parts of the working fluid from at least a heat exchanger in thermal contact with the first volume change chamber.

The method according to claim 1, wherein the working fluid alternates between liquid form and gaseous form. In addition to functioning as a power transmission between the working fluid and the engine, the piston 110 also functions as a common movable partition between the upper cylinder chamber 151 and the lower cylinder chamber 150. In step 5 a pressure drop takes place in that an outlet valve 131 opens and the working fluid is released into a cooling course 4, where in a given time it undergoes cooling at relatively constant volume. Thus the heat engine size may be further reduced, as one does not have to use two separate cylinders for the two different processes. These are attached to each other by mans of known attachment methods. The valve block 103 may further be made with separate courses for thermo-fluid, so that it, in the extension of the lower cylinder 102, may also function as a heat exchanger between a thermo-fluid and a working fluid in contact with it.

Due to rotating motion of the crankshaft 117, the piston 110 will move relatively little around the bottom position, and some of the working fluid will then undergo cooling at relatively constant volume, the total volume being constituted by the sum of the volume of the second cylinder chamber 151 and the volume of the cooling course 4. The unit not only transforms the steam from the distillery process into electricity. There is still time to sign up to this important breakfast debate taking place from 8-9:30 tomorrow morning. The European industrial sector is starting to wake up to the fact that they no longer need to use fossil fuels to run their processes. We are currently in dialogue with production partners for large-scale serial production and in that process, we will have sustainability high on our agenda. It also supplies pre-heated water to the production facility that was previously not possible. All the same, the heat engine cannot function without available heat and cold reservoirs, and they are therefore included as a n part of the total system.

About us

viking heat engines

The second expansion process will be polytropic to start with, as most of the fluid is still in the first chamber having an internal heat exchanger, but as the fluid mass is transferred toward the chamber without a heat exchanger, the process will then also approach a more adiabatic course, as less and less heat may be supplied here. In combustion engines, such as diesel engines, this is relatively simple to solve by stopping the fuel injection before the expansion is completed, and may thereby give the remaining part of the expansion process an adiabatic course, as no more heat than that given by the fuel combustion is supplied. The company was founded in 2009 and currently operates on four continents. It may be made of aluminum, for example. This volume may possibly be evacuated so that vacuum is achieved, which may give the piston assembly 110 an improved thermally insulating effect if desired. When this happens, the total volume of the fluid increases, and because the first chamber is heated, the portion of the fluid still present in this chamber will be supplied with even more heat before it flows out via the bypass. This is very favourable with regard to weight, quantity of construction material, production costs et cetera.

The heating course will also be able to function as a fluid buffer, which among others strengthens the ability of the engine to be able to adapt to varying load, a quantity of heated fluid always being available for injection into the engine. Yesterday I got the airworthiness certificate. This is how the HeatBooster technology works: 1. The top cylinder 101 is also called the upper cylinder and the bottom cylinder 102 is called the lower cylinder. When the piston 110 again reaches the top position, it has displaced nearly the whole amount of working fluid from the second cylinder chamber 151, and the outlet valve 131 closes so that the working fluid is only present in the cooling course 4 wherein it finally undergoes further cooling, but again at constant volume, as the volume of the cooling course 4 will not change substantially since it only consists of relatively stationary components.

As a whole the cooling steps may in a given case be regarded as an isobaric cooling process, provided the cooling course 4 has a certain capacity and the processes take place quickly. Besides engines based on the Stirling or Diesel cycles, one finds in the U. The heating course may at its outlet be provided with a pressure threshold valve such as a cycling valve whose function it is to make sure that the pressure in the heating course is always above a certain level. Thus a net force on the piston in a direction toward the first chamber is achieved throughout this expansion process. When the working fluid is completely cooled and back in liquid form, it may then be reused in a next cycle, as in closed-loop Rankine turbines.
