General ọmụma
Injin M112 nwere njikọ chiri anya na M8 V113. Maka ọtụtụ akụkụ, e mere ha n'otu ebe mmepụta ihe ma nwee ọtụtụ akụkụ ndị yiri ya. Ha abụọ nwere ihe mgbochi cylinder alloy dị ọkụ nwere ihe nkedo nke Silitec (Al-Si alloy) mere. Ejiri otu igwe camshaft maka ahịrị cylinder nke ọ bụla. N'elu crankshaft bụ ogwe nguzozi nke na-atụgharị megide crankshaft n'otu ọsọ ahụ iji belata ịma jijiji.
The camshafts na balancer aro na-chụpụrụ site a abụọ ala yinye. Dị ka M113, M112 nwere valvụ oriri abụọ na otu kpochapu valvụ kwa silinda, nke ndị na-agba ọkụ na-eme ka ọkụ na-arụ ọrụ na hydraulic slack adjuster.
Ojiji nke otu valvụ kpochapu na-ebute mpaghara ọdụ ụgbọ mmiri dị obere ma si otú a na-ebufe ọkụ na-ekpochapu isi na isi isi ala, karịsịa mgbe injin ahụ dị oyi. Yabụ, ihe nrụpụta ahụ na-erute ọnọdụ ọrụ ya ngwa ngwa. Nke a na-enyere aka site na mpempe akwụkwọ mpempe akwụkwọ mpempe akwụkwọ mpempe akwụkwọ na mgbidi abụọ, nke na-etinye obere okpomọkụ.
Ulo oku obula nwere okpukpu abuo na aka nri na aka ekpe nke kpochapu oku. Nhazi nke valves na kandụl bụ symmetrical. N'ihi ọkụ ọkụ abụọ, ibu ọkụ na piston na-abawanye, mmanụ nozzles na-eme ka ọ dị mma, na-agbanye mmanụ mmanụ n'okpuru site na isi piston ahụ.
Emepụtara engine M112 na olu nke 2,4 ruo 3,7 lita. Anyị ga-atụle mgbanwe ndị a n'ụzọ zuru ezu n'okpuru.
N’afọ 2004, eji dochie anya M112 M272 engine.
