Pre combution chamber Direct Injection type

Ruang bakar ditempatkan diantara cylinder head dan bahan bakar langsung diinjeksikan ke ruang bakar

Pre combution chamber terpisah dari cylinder head

Pre combution chamber langsung disatukan dalam cylinder head

Valve Spring. Valve spring mengangkat valve sampai

valve merapat pada valve seat apabila valve sedang menutup. Valve spring juga bekerja mengambalikan rocker arm, push rod dan tappet atau cam follower secara keseluruhan ke posisi normal dengan cepat. Gbr. II - 7. Getaran valve spring.
