- cilindree 3260 cmc
- putere 50 CP / 2800 rpm,

IMS 57 poate atinge o viteza maxima de 80 km/h, consumul fiind de 24 l/100km

Caracteristici: Motorul cu supape laterale, raport de compresie 4,6, arbore cotit cu trei paliere si axa cu came forjate, bloc motor cu cilindri raciti numai la partea superioara, cuzinetii turnati direct in bloc si biele, cutia de viteze manuala cu trei trepte.

M 59 A

TIP: IMS 58 A
- TIP "MAS"
- patru cilindri in linie
- cilindree 3260 cmc
- putere 50 CP / 2800 rpm,



TIP: IMS 59 A
Ulterior putere motorului a fost sporita la 56 CP prin reproiectarea colectoarelor de admisie si evacuare si folosirea carburatorului de conceptie romanesca « UT 550 » (de tip vertical, cu circuit descendent, o singura camera de amestec, dublu difuzor, economizor mecanic si pompa de acceleratie), noul motor fiind codificat IMS 59A

Capacitate cilindrica : 3260 cmc
Cursa x Diametru 107,95 x 98,45
Putere : 50 CP la 2800 rpm / 56 CP la 2900 rpm
Raport de compresie : 4,6 / 5
Cutie de viteze : manuala, cu trei trepte, nesincronizata
Consum mediu : 21 l / 100 km

M59 B

TIP: M207
Motor : patru cilindri in linie, patru timpi, benzina, supape in chiulasa
Capacitate cilindrica : 2512 cmc
Ordinea de aprindere : 1-2-4-3
Diametrul x Cursa (mm) : 97x85
Putere : 70 CP la 3800 rpm
Raport de compresie : 6,72 :1
Cutie de viteze : manuala, cu patru trepte din care sincronizate III si IV

M461

TIP: M207
Motor : patru cilindri in linie, patru timpi, benzina, supape in chiulasa
Capacitate cilindrica : 2512 cmc
Ordinea de aprindere : 1-2-4-3
Diametrul x Cursa (mm) : 97x85
Putere : 70 CP la 3800 rpm
Raport de compresie : 6,72 :1
Cutie de viteze : manuala, cu patru trepte din care sincronizate III si IV

Modelele destinate exportului au beneficiat si de o motorizare diesel, fiind disponibile doua propulsoare: Indenor (2112 cmc / 62 CP) si Perkins (2523 cmc / 71 CP).


M461 C

TIP: M20
Motorul M207 care echipase si modelul M461 si in primii ani de productie ARO M461 C sufera o serie de imbunatatiri incepand cu anul 1973 si este redenumit M20. Modificarile principale vizau sistemul de ungere, pompa de ulei fiind reproiectata si repozitionata central in partea inferiora la tipul M20, filtrul de ulei cu cartus fiind mutat de pe partea stanga pe partea dreapta a motorului. Carburatorul ramane acelasi ca si in cazul modelului M461, W 207/42 DSR-1 fiind fabricat la uzina Carfil Brasov sub licenta Weber (Italia). Bobina de inductie BAR 1 este inlocuita cu modelul 3130 UEPS. M461 si ARO M461 folosesc acelasi tip de electromotor, D 1,2-12 produs de U.M.E.B. Bucuresti.

Motor : patru cilindri in linie, patru timpi, benzina, supape in chiulasa
Capacitate cilindrica : 2512 cmc
Ordinea de aprindere : 1-2-4-3
Diametrul x Cursa (mm) : 97x85
Putere : 77 CP la 4000 rpm
Raport de compresie : 7,2 :1
Cutie de viteze : manuala, cu patru trepte din care sincronizate III si IV
Consum mediu : 14 l / 100 km
Viteza maxima : 100 km/h

Din motive fiscale modelele destinate exportului, pe anumite piete, au fost dotate cu motoare de 2495 cmc, 80 CP la 4200 rpm si raport de compresie 8:1, denumite ARO L-25, capacitate cilindrica obtinuta prin micsorarea cursei pistonului cu 0.6 mm.

M473

La M473 se foloseau multe componente de la ARO 24. De exemplu, nu mai avea motorul M207, acesta a fost inlocuit de motorul L25

Motor: ARO L25 (BENZINA)
4 cilindrii in linie, 4 timpi, aprindere prin scanteie
Aspirat - admisie naturala, carburator, benzina CO 90
Raport de compresie: 8:1
Alezaj x cursa - mm: 97 x 84.4
Capacitate cilindrica - cmc: 2495
Putere maxima - kW(CP)/rpm: 61(83)/4200-4400
Cuplu maxim - Nm(kgfm)/rpm: 160(16.3)/2800-3000

Foarte frumos materialul.

A existat parca si un diesel Perkins in serie foarte limitata pentru export, daca nu ma insel, dar desigur ca nu am alte detalii.
