2.2 Ubusumbane bwubuso hamwe nuburemere bwibipimo byo gupima Ubuso bwubuso bwa valve y'urushinge bupimwa kandi hejuru yubuso busabwa bwa valve y'urushinge ni 61HRC ～ 65HRC kugirango bishoboke gukomera. Ubukonje bwa valve y'urushinge hamwe na kashe ya HHM ni Ra0.03 Rt0.34, naho ubukana bwo hejuru ni 60.4HRC ～ 60.7HRC; inshinge ya inshinge ifite kashe ya numero HD ni Ra0.02, Rt0.37, naho gukomera hejuru ni 62.3HRC. Ubukomere nubukomezi bwimyanya ibiri yinshinge yatanzwe kugirango igenzurwe byose byujuje ibisabwa. Urusenda rumaze gucibwa, hapimwe umwobo w'imbere. Umwobo w'imbere usabwa gukomera nozzle yari 0.05Rt0.8. Agaciro Ra0.07 ～ 1.16, Rt0.82 ～ 1.79. Umwobo w'imbere ubunebwe bwa nozzles ebyiri zatanzwe kugirango ugenzurwe ntabwo wujuje ibyashizweho.

2.3 Ibipimo byo gupima uburinganire nubushakashatsi bwisesengura ryibyuma Ubuso bwubuso bwa valve inshinge burasabwa kuba 61HRC-65HRC, bainite yubusa ntibyemewe kandi austenite isigaye ntirenza 5%. Ubukomezi bwa valve inshinge hamwe numero yambere ya kashe HHM ni 62.9HRC ～ 63.6HRC, ingano yingano ni 10, naho urugero rwa superheat ni 2; ubukana bwa valve y'urushinge hamwe na kashe ya mbere ya kashe ya HD ni 62.4HRC ～ 63.4HRC, ingano yingano ni 9 naho urugero rwa superheat ni 2. Ubukomezi bwimyanya ibiri y'urushinge byose bujuje ibisabwa.
