Description

468 777 2 figurerna och ett föredraget utföringsexempel, där: Fig. 1 visar schematiskt uppbyggnaden av ett seriesekven- tiellt arbetande turboaggregat, Fig. 2 visar schematiskt ett motorpaket sett framifrån, och Fig. 3 visar samma motorpaket sett i en sidovy. 468 777 2 the figures and a preferred embodiment, where: Fig. 1 schematically shows the construction of a series-sequentially operating turbocharger, Fig. 2 schematically shows an engine package seen from the front, and Fig. 3 shows the same engine package seen in a side view.

I fig.1 visas ett turboarrangemang enligt uppfinningen.Fig. 1 shows a turbo arrangement according to the invention.

Detta innefattar ett första turboaggregat 1 samt ett andra turboaggregat 2, vilket är större än det första turbo- aggregatet 1. Detta senare är dock ingen nödvändighet.This comprises a first turbocharger 1 and a second turbocharger 2, which is larger than the first turbocharger 1. However, the latter is not necessary.

Vidare finns på aggregatets luftsida anordnad en första reglerventil 3, som i detta fall är en backventil. På avgassidan finns en styrbar andra reglerventil 4 anordnad.Furthermore, a first control valve 3 is arranged on the air side of the unit, which in this case is a non-return valve. On the exhaust side, a controllable second control valve 4 is arranged.

Vid det första turboaggregatet 1 finns en första waste- gate-ventil 5 och vid det andra turboaggregatet finns en andra waste-gate-ventil 6, vilka båda är styrbara.At the first turbocharger 1 there is a first waste gate valve 5 and at the second turbocharger there is a second waste gate valve 6, both of which are controllable.

I anslutning till insuget hos motorn finns en roterande insugningsventil 7 vars öppning resp. stängning är styrd med avseende på funktionen hos den/de "ordinarie" konven- tionella insugningsventilen/-erna 8. På sedvanligt vis finns avgasventiler 9 anordnade vid cylinderhuvudet.Adjacent to the intake of the engine is a rotary intake valve 7 whose opening resp. closing is controlled with respect to the function of the "ordinary" conventional intake valve (s) 8. Exhaust valves 9 are arranged in the usual manner at the cylinder head.

Beteckningen 10 anger en givare för mätning av avgasernas temperatur. Vidare symboliserar beteckningen 11 en varv- talsgivare och 12 det ordinarie konventionella gasspjället.The designation 10 indicates a sensor for measuring the temperature of the exhaust gases. Furthermore, the designation 11 symbolizes a speed sensor and 12 the ordinary conventional throttle.

I figur 2 visas, i en vy framifrån, en förbränningsmotor 13 med tilhörande turboarrangemang. Förbränningsmotorn 13 utgörs här av en radmotor, men även andra motortyper såsom exempelvis V-motorer är tänkbara. Det första turbo- aggregatet 1 är' placerat i anslutning' till motorns 13 grenrör. Det andra turboaggregatet 2 är placerat på samma "kr 468 77 3 sida av motorn 13 som det första turboaggregatet 1, och nedanför detta. Genom denna placering uppnås fördelar med avseende på utlopp samt inplacering av turbinventil hos det första aggregatet 1. Genom att i det visade utförandet det andra aggregatet 2 placeras något förskjutet till vänster (se fig. 3) i förhållande till det första aggregatet 1 uppnås en packningstekniskt elegant dragning av det första aggregatets 1 utloppsledning.Figure 2 shows, in a front view, an internal combustion engine 13 with associated turbo arrangement. The internal combustion engine 13 here consists of a row engine, but other engine types such as, for example, V engines are also conceivable. The first turbocharger 1 is 'placed next to' the manifolds of the engine 13. The second turbocharger 2 is located on the same "kr 468 77 3 side of the engine 13 as the first turbocharger 1, and below this. Through this placement advantages are obtained with respect to the outlet and placement of the turbine valve of the first generator 1. By in the In the embodiment shown, the second assembly 2 is placed slightly offset to the left (see Fig. 3) in relation to the first assembly 1, a packing-technically elegant drawing of the outlet line of the first assembly 1 is achieved.

I figur 3 åskådliggörs förbindelser för luft och avgaser mellan de båda turboaggregaten 1, 2, samt ventilen 4.Figure 3 illustrates connections for air and exhaust gases between the two turbochargers 1, 2, and the valve 4.

Med ett arrangemang enligt den föreliggande uppfinningen uppnås en liten bredd hos det kompletta motorpaketet, vilket medför att inbyggnadsbredden i motorrummet minskas.With an arrangement according to the present invention, a small width of the complete engine package is achieved, which means that the installation width in the engine compartment is reduced.

Dessutom uppnår man för turbofunktionen gynnsamma ström- ningsförhållanden eftersom man använder korta avgas- och luftledningar. Detta är gynnsamt för båda turboaggregaten 1, 2. Genom att undvika långa "transportsträckor" för luft- och risken och avgasflödena minskas för temperatur- tryckförluster i ledningarna. 7In addition, favorable flow conditions are achieved for the turbo function because short exhaust and overhead lines are used. This is favorable for both turbochargers 1, 2. By avoiding long "transport distances" for the air and the risk and the exhaust gas flows are reduced for temperature pressure losses in the lines. 7
