Zylinder jeweils um 180° und die Kurbeln für den 1. Zylinder und den 3. Zylinder um 90° gegeneinander versetzt angeordnet sind, und mit einer Zündfolge 1-3-2-4 in nichtäquidistanten Zündabständen 90°-180°-270°-180°4-cylinder 4-stroke piston internal combustion engine with a crankshaft, in which the cranks 1, 2, 3, 4) for the 1st and the 4th cylinder and for the 2nd and 3rd cylinder each 180 ° and the Cranks for the 1st cylinder and the 3rd cylinder are offset by 90 ° from each other, and with a firing order 1-3-2-4 in non-equidistant firing intervals 90 ° -180 ° -270 ° -180 °
Description
Für den Kauf eines Personenkraftwagens sind nicht nur die technischen Daten wie Leistung, Straßenlage, Bequemlichkeit des Fahrgastraumes, Fassungsvermögen des Kofferraumes oder dergl. sowie das Design der Karosserie ausschlaggebend. Vielfach spielt auch der akustische Eindruck des Motorgeräusches, d. h. die Klangcharakteristik bzw. der ”Sound” eine Rolle bei der Kaufentscheidung. Für 4-Zylinder-4-Takt-Verbrennungskraftmaschinen sind verschiedene Konzepte bekannt, eine Zündreihenfolge und -abstand vorzusehen.For the purchase of a passenger car are not just the technical data like Performance, roadholding, Comfort of the passenger compartment, capacity of the trunk or the like the design of the body is crucial. Often plays too the acoustic impression of the engine noise, d. H. the sound characteristic or the "sound" a role at the purchase decision. For 4-cylinder 4-stroke internal combustion engines Different concepts are known, a firing order and distance provided.

Die Klangcharakteristik eines konventionellen 4-Zylinder-4-Taktmotors ist jedoch mit dem ”vollen Klang” eines beispielsweise 6-Zylinder- bzw. 8-Zylinder-V-Motors nicht zu vergleichen.The However, the sound characteristic of a conventional 4-cylinder 4-stroke engine is with the "full Sound "one For example, 6-cylinder or 8-cylinder V-engine not to compare.
Der Erfindung liegt die Aufgabe zugrunde, eine 4-Zylinder-4-Takt-Kolbenbrennkraftmaschine zu schaffen, die gegenüber herkömmlichen 4-Zylinder-4-Takt-Kolbenbrennkraftmaschinen eine markantere Klangcharakteristik aufweist.Of the Invention is based on the object, a 4-cylinder 4-stroke piston internal combustion engine to create that opposite usual 4-cylinder 4-stroke piston internal combustion engines a more distinctive sound characteristics having.
Diese Aufgabe wird erfindungsgemäß gelöst durch eine 4-Zylinder-4-Takt-Kolbenbrennkraftmaschine mit einer Kurbelwelle, bei der die Kurbeln für den 1. und den 4. Zylinder sowie für den 2. und den 3. Zylinder jeweils um 180° und die Kurbeln für den 1. und den 3. Zylinder um 90° gegeneinander versetzt angeordnet sind, und mit einer Zündfolge 1-3-2-4 in nichtäquidistanten Zündabständen von 90°-180°-270°-180°. Während sich für den normalen 4-Zylinder-Reihenmotor mit 180° gekröpfter Kurbelwelle und der gebräuchlichen Zündfolge 1-3-4-2 bei 180° Zündabstand bereits feste Randbedingungen für die Anregungen der geräuschbestimmenden Schwingungsanregungen bestehen, also hauptsächlich die 2., 4. usw. Ordnung der Oberschwingungen angeregt werden, ergibt sich bei der erfindungsgemäßen Zündfolge 1-3-2-4 mit der erfindungsgemäß gekröpften Kurbelwelle und den daraus resultierenden nichtäquidistanten Zündabständen, daß sowohl im Gaswechsel als auch in der Bewegung der Kolbenbrennkraftmaschine relativ zum Fahrgestell eine andere Schwingungsanregung, nämlich der Ordnungen 0.5, 1.5, 2.5, 3.5, 4, 4.5 etc. Diese geänderte Zusammensetzung des Frequenzspektrums bewirkt einen wesentlich kraftvolleren Klangeindruck. Die freien Massenkräfte sind bis zur 4. Ordnung ausgeglichen, während das auftretende freie Massenmoment 1. Ordnung in üblicher Weise durch eine Ausgleichswelle mit entsprechend ausgerichteten Gegengewichten ausgleichbar ist.These The object is achieved by a 4-cylinder 4-stroke reciprocating internal combustion engine with a crankshaft, when the cranks for the 1st and 4th cylinder and for the 2nd and the 3rd cylinder each by 180 ° and the cranks for the 1st and the 3rd cylinder at 90 ° to each other are staggered, and with a firing order 1-3-2-4 in non-equidistant Ignition intervals of 90 ° -180 ° -270 ° -180 °. While for the normal 4-cylinder in-line engine with 180 ° cranked crankshaft and the usual firing 1-3-4-2 at 180 ° firing interval already fixed boundary conditions for the suggestions of the noise-determining vibration excitations exist, so mainly the 2nd, 4th, etc. order of the harmonics are excited in the ignition sequence according to the invention 1-3-2-4 with the invention cranked crankshaft and the resulting non-equidistant firing intervals, that both in Gas exchange as well as in the movement of the reciprocating internal combustion engine relative to the chassis another vibrational excitation, namely the Orders 0.5, 1.5, 2.5, 3.5, 4, 4.5 etc. This modified composition of the frequency spectrum causes a much more powerful sound impression. The free mass forces are balanced up to the 4th order, while the occurring free Mass moment 1st order in usual Way through a balance shaft with appropriately aligned Counterweights compensated.
