3-LABORATORIYa ISHI

Ichki yonuv dvigatelining yuklanish tavsifi

Laboratoriya ishini bajarish sanasi: __________________________

Laborotoriya ishini bajarayotganda o’qituvchining tavsiyasiga binoan nominal aylanishlar chastotasini o’rniga boshqa kiymatlarida ham utkazish mumkin.

Tajriba o’tkazilayotgan vaktda 1-laborotoriya ishida kursatilgan ko’rsatgichlar qayd qilinadi va hisoblangan ko’rsatgichlar bilan birga 1-jadvalga uxshash tuzilgan jadvalga kiritiladi.
Hisobotda yoritilishi kerak: 1-laborotoriya ishining hisoboti uchun keltirilgan 1-, 2-, 3- va 4-bandlaridan tashqari karbyuratorli dvigatelning yuklanish tavsifi va uning taxlili.
Dvigatellarni aralashma tarkibi bo’yicha
rostlash tavsifi

4-LABORATORIYa ISHI

Ichki yonuv dvigatelining tezlik tavsiflari

Laboratoriya ishini bajarish sanasi: __________________________

Tajribalarni utkazish davomida 1-laboratoriya ishida qayd qilingan ko’rsatgichlar ulchanadi va hisoblanadi.

Ulchangan va hisoblash natijasida aniklangan ko’rsatgichlar 1-jadvalga uxshash tuzilgan 4-jadvalga kiritiladi.
