Sezvinhu zvikuru, mabhuroko eenjini nemabhuroko emasilinda einjini zvinofanira kumira tembiricha yakakwira nekumanikidzwa, kuve nechokwadi chekuvharwa kwakavimbika, uye kupa kuenderana kwakanaka kwekubatanidza. Zviratidzo zvavo zvehunyanzvi, zvinosanganisira kuyedza kuomarara uye kuyedza mativi ekururama, zvese zvinoda kudzorwa kwakasimba uchishandisa michina chaiyo. Kuyedzwa kwekuomarara kwemabhuroko nemabhuroko emasilinda kunonyanya kushandiswa kuongorora hunhu hwemakanika hwezvinhu, kuve nechokwadi chekuti zvinosangana nezvinodiwa zvekugadzira.
Zviyedzo zvekusimbisa hunyoro zveRockwell zvakakodzera kuongorora hunyoro hwenzvimbo dzakakura, dzakati sandara dzakadai semabhuroko ecylinder (semuenzaniso, nzvimbo dzinobatanidza musoro wecylinder, mabhuroko ecylinder) uye crankshaft hole end faces. Kuti uongorore hunhu hwepamhepo mumitsetse yekugadzira, zvinodiwa zvekuongorora zvakagadzirwa zvinogona kupihwa. Zviyedzo zvekusimbisa hunyoro zveRockwell zvinongoerekana zvaitwa zvinogona kubatanidzwa nemutsetse wekugadzira kuti zvibudirire, zvichiratidza kushanda kwepamusoro uye mhedzisiro yakagadzikana. Iyi nzira yekuedza ndiyo inonyanya kushandiswa mukugadzira zvinhu zvemotokari uye inoenderana neISO 6508 neASTM E18 standards.
Zviyedzo zveBrinell hardness zvinoshandiswa pakuongorora kuomarara kwezvisina maburi zvecylinder block nezvikamu zvine madziro akakora (semuenzaniso, mativi ecylinder block), uye zvinonyanya kukodzera pakuongorora kunaka kwekukanda uye kushanda kwekupisa kwezviyero zvecylinder iron cast iron. Zvinofanira kucherechedzwa kuti kuyedza Brinell kunosiya maburi makuru, saka kunofanira kudzivirirwa pazvikamu zvinokurumidza kukuvara zvakaita senzvimbo dzemukati dzemadziro ecylinder nepamusoro pemachina akagadzirwa nemazvo.
Zviyedzo zvekusimbisa hunyoro zveVickers zvakakodzera pakuyedza hunyoro hwezvikamu zvakatetepa zvealuminium alloy cylinder blocks, silinda liner inner surfaces (kudzivirira kukuvadza sealing surfaces), pamwe nekuyedza hunyoro hwehunyoro hwezvikamu zvakagadziriswa nekupisa uye macoatings (semuenzaniso, nitrided layers, quenched layers) pamusoro pema cylinder block. Nzira iyi yekuyedza inosangana nezvinodiwa zvekuyedza nemazvo zvemuchadenga uye mainjini emotokari emhando yepamusoro, uye inoenderana neISO 6507 neASTM E92 standards.
Zvichienderana nemabhuroko emasilinda nemisoro yemasirinda yakagadzirwa nezvinhu zvakasiyana, zviyero zvekuomarara zvinotevera zvinogona kutaurwa:
| Chikamu | Zvinhu Zvakajairika | Rudzi rweKuoma Kwekuoma (HB/HV/HRC) | Chinangwa Chekuedza Kwakakosha |
| Kandai Simbi Sirinda Chivharo | HT250/HT300 (Simbi Yakakandwa Yegrey), Simbi yeGraphite Yakatsetseka | 180-240HB20-28HRC | Iva nechokwadi chekuti hapana chekupfeka uye hapana chekupfeka |
| Aruminiyamu chiwanikwa Cylinder Block | A356+T6, AlSi11Cu2Mg | 85-130 HB90-140 HV 15-25 HRC | Simba rakaringana uye kugona kushanda zvakanaka |
| Kandai Simbi Cylinder Musoro | HT200/HT250, Simbi yeDuctile | 170-220 HB18-26 HRC | Ramba uchitsungirira kupisa kwakanyanya uye iva nechokwadi chekuti nzvimbo yacho yakasimba |
| Aruminiyamu chiwanikwa sirinda musoro | A356+T7, AlSi12Cu1Mg1Ni | 75-110 HB80-120 HV 12-20 HRC | Kuenzanisa zvinhu zviri nyore, kupisa uye simba rechimiro |
Zvichienderana nezvinodiwa zvakasiyana-siyana zvekuedza zvemabhuroko emasilinda einjini, Laizhou Laihua inogona kupa mhinduro dzakagadzirwa zvichienderana nezvigadzirwa zvakasiyana. Izvi zvinosanganisira mamodheru akajairwa, mamodheru akagadziriswa emhando dzese dzeRockwell, Brinell, uye Vickers hardness testers, pamwe nekugadzirwa kwezvishandiso zvakasarudzika zvakagadzirirwa zvigadzirwa—zvese zvine chinangwa chekusimudzira mashandiro ekuedza uye kururama kwekuyera.
