Jwalo ka dikarolo tsa mantlha, diboloko tsa disilindara tsa enjene le dihlooho tsa disilindara di tlameha ho mamella dithempereichara tse phahameng le kgatello, ho netefatsa ho kwalwa ho tshepahalang, le ho fana ka tumellano e ntle ya kopano. Ditshupo tsa tsona tsa tekheniki, ho kenyeletswa le teko ya ho thatafala le teko ya ho nepahala ha dibopeho, kaofela di hloka taolo e tiileng ho sebediswa disebediswa tse nepahetseng. Teko ya ho thatafala ha diboloko tsa disilindara le dihlooho e sebediswa haholoholo ho lekola thepa ya mechini ya thepa, ho netefatsa hore di fihlela ditlhoko tsa moralo.
Liteko tsa ho thatafala ha Rockwell li loketse ho hlahloba ho thatafala ha libaka tse kholo, tse bataletseng tse kang lifofane tsa li-cylinder block (mohlala, libaka tsa ho kopana ha hlooho ea cylinder, li-bottoms tsa li-cylinder block) le lifahleho tsa ho qetela tsa masoba a crankshaft. Bakeng sa tlhahlobo ea boleng ba inthanete meleng ea tlhahiso, litlhoko tsa liteko tse ikhethileng li ka fanoa. Liteko tsa ho thatafala ha Rockwell ka boiketsetso li ka kopanngoa le mohala oa tlhahiso ho fihlela ts'ebetso e sa laoleheng, e nang le bokhoni bo phahameng le liphetho tse tsitsitseng. Mokhoa ona oa teko ke oona o sebelisoang haholo tlhahisong ea likarolo tsa likoloi 'me o latela maemo a ISO 6508 le ASTM E18.
Liteko tsa ho thatafala ha Brinell lia sebetsa bakeng sa teko ea ho thatafala ha li-blank tsa cylinder block le likarolo tse nang le mabota a teteaneng (mohlala, mabota a mahlakoreng a cylinder block), 'me li loketse haholo bakeng sa ho lekola boleng ba ho lahla le katleho ea kalafo ea mocheso ea li-block tsa cylinder tsa tšepe e lahletsoeng. Ho lokela ho hlokomeloa hore teko ea Brinell e siea masoba a maholo, kahoo e lokela ho qojoa likarolong tse senyehang habonolo joalo ka libaka tse ka hare tsa lebota la cylinder le libaka tse entsoeng ka mokhoa o nepahetseng.
Liteko tsa ho thatafala ha Vickers li loketse bakeng sa teko ea ho thatafala ha likarolo tse nang le mabota a masesaane a li-cylinder blocks tsa aluminum alloy, li-cylinder liner inner surfaces (ho qoba ho senya li-tieving surfaces), hammoho le teko ea ho thatafala ha li-layer le li-coat tse phekotsoeng ka mocheso (mohlala, li-layer tse nang le nitride, li-layer tse timmeng) holim'a li-cylinder block. Mokhoa ona oa teko o fihlela litlhoko tsa tlhahlobo e nepahetseng ea lienjine tsa lifofane le tsa likoloi tsa maemo a holimo, 'me o latela maemo a ISO 6507 le ASTM E92.
Ho ya ka diboloko tsa disilindara le dihlooho tsa disilindara tse entsweng ka thepa e fapaneng, sekala se latelang sa thatafalo se ka supjwa:
| Karolo | Lisebelisoa tse Tloaelehileng | Sebaka sa Litšupiso tsa Bothata (HB/HV/HRC) | Morero oa Teko ea Motheo |
| Lahleloa Tšepe Silindara Block | HT250/HT300 (Tšepe e Putsoa), Tšepe ea Graphite e Tšoeu | 180-240HB20-28HRC | Netefatsa ho hanyetsa ho tsofala le ho hanyetsa ho fetoha ha sebopeho |
| Aluminium Alloy Cylinder Block | A356+T6, AlSi11Cu2Mg | 85-130 HB90-140 HV 15-25 HRC | Matla a ho leka-lekanya le ho sebetsa hantle ha mechini |
| Hlooho ea Moqomo oa Tšepe e Lahliloeng | HT200/HT250, Tšepe e qhibilihisitsoeng | 170-220 HB18-26 HRC | Emamella tšusumetso ea mocheso o phahameng 'me u netefatse hore bokaholimo bo tiile |

Ho latela litlhoko tse fapaneng tsa liteko tsa li-block tsa silindara tsa enjene, Laizhou Laihua e ka fana ka litharollo tse ikhethileng ho latela lihlahisoa tse itseng. Sena se kenyelletsa mehlala e tloaelehileng, mehlala e ikhethileng ea mefuta eohle ea liteko tsa ho thatafala ha Rockwell, Brinell, le Vickers, hammoho le moralo oa lisebelisoa tse ikhethileng tse etselitsoeng lihlahisoa - tsohle li reretsoe ho ntlafatsa ts'ebetso ea liteko le ho nepahala ha tekanyo.
