Saka, mutsauko uripo pakati peinjini yekutsva yemukati mutsva ndewekuti:

• zviyero zvemasilinda mudenderedzwa zvakaderedzwa kusvika 82 mm (paM137 yaive 84 mm), izvo zvakaita kuti zvibvirire kudzikisa huwandu hwekushanda kusvika 5,5 malita uye kukora nzvimbo yakasununguka pakati pezvinhu zveCPG;
• kuwedzera kwekuparadzanisa, zvakare, kwakaita kuti zvikwanise kugadzira nzira mbiri dzekutenderera kweantifreeze;
• iyo isina-fated ZAS system, kuvhara masilinda akati wandei pakuremerwa injini uye kugadzirisa kuratidzwa kwecamshafts, yakabviswa zvachose;
• iyo yemagetsi injini manejimendi system yakatsiviwa neimwe yazvino vhezheni;
• iyo DMRV yakabviswa - maregulator maviri akashandiswa pachinzvimbo;
• yakabvisa 4 lambda probes, iyo yakapa hukuru hukuru kune injini;
• kuitira zviri nani kudzvanywa kwemafuta, pombi yemafuta yakasanganiswa neiyo control unit uye iri nyore sefa - isina kutariswa pombi yemafuta yakaiswa paM137, kusanganisira sensor yakabatanidzwa;
• iyo inopisa inopisa mukati mevhavha yevhavha yakabviswa, uye radiator yakajairwa yakaiswa panzvimbo yayo pamberi;
• centrifuge yakawedzerwa kune exhaust ventilation system;
• compression yakaderedzwa kusvika 9.0;
• chirongwa chakashandiswa nema turbines maviri akaiswa mune exhaust manifolds - iyo inosimudzira inotonhodzwa nematanho maviri ari pamusoro pemusoro wecylinder.

Nekudaro, iyo M275 inoshandisa yakafanana 3-vharuvhu dhizaini yakashanda zvakanaka paM137.

Verenga zvakawanda nezve musiyano pakati peM275 neM137 injini.
