Abstract
Description
Compact ontwerp van een motor, de dubbelmotor, met een primair arbeidsproces van een interne verbrandingsmotor en een secundair arbeidsproces van een stirlingmotor. De cilinders van beide processen zijn gescheiden maar als één geheel compact vormgegeven. De twee 5 arbeidsprocessen worden samengebracht op de krukas of door de zuigerstangen te verbinden.Compact design of an engine, the dual engine, with a primary work process of an internal combustion engine and a secondary work process of a stirling engine. The cylinders of both processes are separate but have a compact design. The two work processes are brought together on the crankshaft or by connecting the piston rods.
De uitvinding is een motor, dubbelmotor met één primair arbeidsproces geleverd door een verbrandingsmotor en één secundair 10 arbeidsproces geleverd door een stirlingmotor. Het secundaire arbeidsproces wordt gevoed door de restwarmte van het verbrandingsproces in de verbrandingsmotor. Deze restwarmte opgeslagen in de constructie van de verbrandingsmotor en de uitlaatgassen worden door een warmtewisselaar en warmtegeleiding via 15 de cilinderwanden verplaats naar de stirlingmotor. De stirlingmotor functioneert door een temperatuurverschil tussen de warme zijde en koude zijde. De warmtebron voor de warme zijde is de warmtewisselaar de koude zijde wordt gekoeld door een koelsysteem. Dit koelsysteem staat zijn warmte af aan de buitenlucht. De twee arbeidsprocessen van 20 de dubbelmotor worden samengebracht op de krukas of door de zuigerstangen te verbinden. De dubbelmotor kent een compact vormgegeven cilinder dubbel, de dubbelcilinders. De dubbelcilinder combineert één cilinder van de verbrandingsmotor met één cilinder van de stirlingmotor. Indien in het ontwerp alleen de dubbelcilinder 25 wordt toegepast dan is altijd het aantal cilinders van de stirlingmotor gelijk aan die van de verbrandingsmotor. De dubbelcilinder bestaat uit intern één cilinder van de verbrandingsmotor waar omheen één annulervormige cilinder van de stirlingmotor of omgekeerd één interne cilinder van de stirlingmotor 30 waar omheen één annulervormige cilinder van de verbrandingsmotor.The invention is an engine, dual engine with one primary working process supplied by a combustion engine and one secondary working process supplied by a stirling engine. The secondary work process is fed by the residual heat from the combustion process in the combustion engine. This residual heat stored in the construction of the combustion engine and the exhaust gases is transferred to the stirling engine via a heat exchanger and heat conduction via the cylinder walls. The Stirling engine functions due to a temperature difference between the warm side and cold side. The heat source for the warm side is the heat exchanger, the cold side is cooled by a cooling system. This cooling system transfers its heat to the outside air. The two working processes of the double engine are brought together on the crankshaft or by connecting the piston rods. The double engine has a compact double cylinder, the double cylinders. The double cylinder combines one cylinder of the combustion engine with one cylinder of the Stirling engine. If only the double cylinder 25 is used in the design, then the number of cylinders of the stirling engine is always the same as that of the combustion engine. The double cylinder consists of one internal cylinder of the internal combustion engine around which one canceling cylinder of the Stirling engine or vice versa one internal cylinder of the internal combustion engine 30 around which one canceling cylinder of the internal combustion engine.
De warmteoverdracht vindt plaats via de warmtewisselaar en via warmtegeleiding door de cilinderwanden. De dubbelmotor kan in elke cilinderconfiguratie onder andere van de lineaire en V-vorm met elke variatie aan cilinderaantallen worden toegepast. De dubbelmotor kan 35 als zelfstandige mechanische aandrijfeenheid worden ingezet zowel als in gecombineerde configuraties zoals de hybride oplossingen. Men kan dubbelmotoren samenstellen gebruikmakend van verschillende typen 10339 74 2 interne verbrandingsmotoren en verschillende typen stirlingmotoren.The heat transfer takes place via the heat exchanger and via heat conduction through the cylinder walls. The dual engine can be used in any cylinder configuration, including the linear and V-shape with any variation in cylinder numbers. The dual motor can be used as an independent mechanical drive unit as well as in combined configurations such as the hybrid solutions. Double engines can be assembled using different types of internal combustion engines and different types of stirling engines.
De dubbelcilinder maakt het mogelijk een dubbelmotor te construeren nauwelijks groter dan een enkelvoudige verbrandingsmotor. De dubbelcilinder maakt het ook mogelijk de dubbelmotor toe te passen in 5 een free-piston motorconfiguratie.The double cylinder makes it possible to construct a double engine barely larger than a single combustion engine. The double cylinder also makes it possible to use the double engine in a free-piston engine configuration.
Het gebruik van een interne verbrandingsmotor en een stirlingmotor om een hoger gemeenschappelijk rendement te bereiken is eerder toegepast. Ook is bij dit soort combinaties eerder gekozen voor een compact ontwerp van de cilinders waarbij de twee arbeidsprocessen 10 werden samengevoegd door gebruik te maken van een gecombineerde cilinder. Dit samenvoegen stelt specifieke eisen aan de te gebruiken afdichtingtechnieken en limiteert de ontwerpvrijheid. Bij de dubbelmotor is deze compactheid gerealiseerd en zijn de cilinders gescheiden gebleven. Het samenvoegen tot één arbeidsproces geschied 15 door het verbinden van de zuigerstangen of op de krukas. Hierdoor is het mogelijk bewezen technieken te gebruiken en is de vrijheid ontstaan voor het gebruik van vele type interne verbrandingsmotoren in combinatie met verschillende varianten van de stirlingmotor.The use of an internal combustion engine and a stirling engine to achieve a higher common efficiency has previously been applied. In this type of combination, a compact design of the cylinders was also chosen, whereby the two working processes were combined by using a combined cylinder. This merging places specific demands on the sealing techniques to be used and limits design freedom. With the dual engine this compactness has been realized and the cylinders have remained separate. The merging into one working process takes place by connecting the piston rods or on the crankshaft. This makes it possible to use proven techniques and the freedom has arisen for the use of many types of internal combustion engines in combination with different variants of the Stirling engine.
