QUALITY CONTROL AT PROCESS OF ENGINE ASSEMBLY

U radu je analiziran postupak izbora četverotaktnog benzinskog motora za proizvođača radnog uređaja prema specifikacijama i zahtjevima proizvođača uređaja. Rad se fokusira na postupke kontrole kvalitete procesa montaže motora, kao i na postupke kontrole karakteristika motora na ugrađenom stroju u svrhu praćenja normi i propisa koje uređaj u radu mora poštovati. Ovisno o vrsti uređaja na koji se motor ugrađuje, dane su različite specifikacije i norme za određivanje bruto snage motora te neto snage uređaja za rad pod opterećenjem.The thesis analizes the procedure of choosing a four stroke petrol powered engine for use in power equipment, based on the specifications and demands by the equipment manufacturer. The thesis puts focus on quality control procedures during the engine mounting, as well as engine performance control after mounting in order to closely monitor the performance and its compliance with norms and legislations that it has to meet. Depending on the type of a powered machine, different specifications are given, as well as different standards and norms for determining engine gross power and net power for under-load conditions
