Abstract

An intake system for internal combustion engines incorporating a filter housing (10) with an air intake opening (11), a filter element (12) and at least one air outlet tube (13), which communicates with the engine inlet manifolds (16), which form an integral unit with the bottom part of the filter housing (10). The top part (19) of the inlet manifolds (16) are designed to form the lowermost border of the filter housing (10), and to provide a support for the filter element (12). Hereby is obtained a compact and space-saving construction. <IMAGE>

Description

15 20 25 30 35 502 372 2 Beskrivning av utföringsexempel V \ Insugningssystemet enligt fig. 1 innefattar ett filterhus 10 med ett luftintag 11, ett filterelement 12 och minst en luftutloppsstos 13. Filterhuset 10 innesluter det utbytbara, rörformiga filterelementet 12. Luftintaget ll är placerat vid filterhusets 10 ena gavel medan mnioppsstosen 13 är ansluten till det rörformiga filterelementets 12 öppning. Description of embodiment V The intake system according to Fig. 1 comprises a filter housing 10 with an air inlet 11, a filter element 12 and at least one air outlet socket 13. The filter housing 10 encloses the replaceable, tubular filter element 12. The air inlet 11 is located at one end of the filter housing 10 while the socket 13 is connected to the opening of the tubular filter element 12.

Från luftintaget 11 leds luften via en runtomgáende luftvo- lym 14 genom filterelementet 12 och till luftutloppsstosen.From the air intake 11, the air is led via a circumferential air volume 14 through the filter element 12 and to the air outlet nozzle.

Utloppsstosen 13 uppvisar ett spjäll 15 och mynnar i en gemensam volym varifrån insugningsluften fördelas till motorcylindrarnas respektive insugningsrör 16. Inloppsdelen 17 till dessa insugningsrör 16 är lurformad och uppvisar en inloppsöppning 18 vilken kommunicerar med utloppsstosen 13, varifrån insugningsluften via ett luftutrymme i luren 17 leds vidare till insugningsröret 16. Detta uppvisar ett övre väsentligen plant parti 19, mot vilket en del av filterhuset 10 ansluter och således bildar en del av dettas nedre be- gränsning och tätning. En mycket kompakt och utrymmessnàl konstruktion àstadkommes härigenom.The outlet nozzle 13 has a damper 15 and opens into a common volume from which the intake air is distributed to the engine cylinders' respective intake pipes 16. The inlet part 17 of these intake pipes 16 is lure-shaped and has an inlet opening 18 which communicates with the outlet nozzle 13. to the suction pipe 16. This has an upper substantially flat portion 19, to which a part of the filter housing 10 connects and thus forms part of its lower boundary and seal. A very compact and space-saving construction is thereby achieved.

I fig. 2 visas ett insugninssystem för en sexcylindrig motor med var sitt insugningsrör 16. Utloppsstosen 13 frán filter- huset 10 är centralt placerad och luften fördelas härifrån till samtliga sex insugningsrör 16. Filterelementet 12 (ej visat) placeras således direkt pà det paket som bildar insugningssystemet, varvid insugningsrörens 16 övre parti 19 bildar botten till filterhuset. Det mot filterhuset 10 an- slutande partiet 19 av insugningsrören 16 är krökta men kan även vara plana, varvid filterhuset 10 ges en motsvarande utformning. Själva filterelementet 12 placeras mot en tät- ningsring 22 i ett spar 24, vilket har en mot filterelemen- tets tvärsnitt svarande form, som i det visade exemplet är oval.Fig. 2 shows an intake system for a six-cylinder engine, each with an intake pipe 16. The outlet nozzle 13 from the filter housing 10 is centrally located and the air is distributed from here to all six intake pipes 16. The filter element 12 (not shown) is thus placed directly on the package forms the suction system, the upper portion 19 of the suction pipes 16 forming the bottom of the filter housing. The portion 19 of the suction pipes 16 adjoining the filter housing 10 is curved but can also be flat, whereby the filter housing 10 is given a corresponding design. The filter element 12 itself is placed against a sealing ring 22 in a groove 24, which has a shape corresponding to the cross-section of the filter element, which in the example shown is oval.

Bränsle tillförs bränsleinsprutningsventil 20, insugningsrörets 16 utloppsdel via en inskruvad i. en gängförsedd 10 "502 372 3 borrning 23 vid insugningsrörens 16 övre del, nära dess ut- loppsmynning. Insprutningsventilens bränsleledning 21 är till en del av sin längd placerad i filterhusets 10 luft- utrymme 14, vilket kommunicerar med luftintaget ll. Härige- nom àstadkommes en kylning av det tillförda bränslet. Alter- nativt kan tillförselröret för bränslet vara ingjutet och bilda en enhet med insugningsrören 16 och även i detta fall kan en del av bränsleledningen vara placerad i filterhusets 10 luftutrymme 14.Fuel is supplied to the fuel injection valve 20, the outlet part of the intake pipe 16 via a screwed into a threaded 10 "502 372 3 bore 23 at the upper part of the intake pipe 16, near its outlet mouth. The fuel line 21 of the injection valve is located part of its filter housing 10 space 14, which communicates with the air intake 11, thereby providing a cooling of the supplied fuel.Alternatively, the supply pipe for the fuel can be molded in and form a unit with the intake pipes 16 and even in this case a part of the fuel line can be placed in the filter housing. 10 air space 14.

Uppfinningen är naturligtvis inte begränsad till det visade utföringsexemplet utan ett flertal varianter är tänkbara inom ramen för patentkraven.The invention is of course not limited to the exemplary embodiment shown, but a number of variants are conceivable within the scope of the claims.
