I réimse an innealra cumhachta, léiríonn innill mhuirí agus gnáth -innill (ag glacadh innill ghluaisteáin mar shampla) difríochtaí soiléire i go leor príomhghnéithe mar gheall ar chásanna éagsúla iarratais .
{1. Ó pheirspictíocht na saintréithe luais, is innill íseal-luais iad innill ghinearálta mara, agus is iondúil go mbíonn an luas faoi bhun 800 rpm (ach amháin i gcás báid luais speisialta) . Is é seo toisc go gcaithfidh innill mhuirí a mheaitseáil le taomairí, agus tá an luas oiriúnach thart ar {}}}}}}}}}}}}}}}}}}}}}}}}}} \\ T Éifeachtúlacht . I gcodarsnacht leis sin, tá raon luais níos leithne ag innill ghluaisteáin, agus tá coinníollacha tiomána na ngluaisteán casta . Ní mór dóibh oibriú ag luasanna difriúla . Mar shampla, is féidir leis an inneall coiteann gásailín luas díomhaoin a bhaint amach nuair a bhíonn luas díomhaoin ag {{{}} RPM, agus an luas a bhaint amach ag RPM ag an luas ag RPM ag RPM ag RPM ag RPM ag an luas ag an luas ag an luas ag an luas ag an luas. go géar {.
2.In terms of fuel selection, marine engines, especially large cargo ships and cruise ship engines, often use heavy oil. Heavy oil is relatively cheap and easy to store and transport, which is suitable for ships' long-term and long-distance navigation needs. However, its combustion characteristics and impurity content require the engine to have a special design to ensure full Dóchán . I ngnáth -innill ghluaisteáin, úsáideann innill ghásailín gásailín mar bhreosla, agus úsáideann innill díosail díosal . Tá riachtanais ardchaighdeáin ag na breoslaí seo chun freastal ar riachtanais chumhachta na n -uathoibrí le héifeachtacht ard agus freagairt thapa go tapa . chomh maith, tá Gasoline géara agus burns go tapa, cé go bhfuil dínit ag dínn go bhfuil dínit ag diesel go bhfuil sé ag} dlús .
3.In terms of structural design and manufacturing process, the structure of marine engines is more solid to withstand vibration, impact and long-term operating load in the marine environment. At the same time, the corrosiveness and moisture of seawater must be considered, and corrosion-resistant materials are mostly used. The cooling system also uses seawater for cooling. Automobile engines pay more attention to lightweight and compactness to reduce the weight of the whole vehicle, improve handling performance and fuel economy, and need to cope with land environments such as dust and different temperatures. They are equipped with high-efficiency air filters and suitable cooling systems.
