Ijenali ye-crankshaft kunye ne-bearing bush zinxitywe kakhulu, kwaye kuyinto eqhelekileyo ukuba ijenali ye-camshaft inxibe kancinci.

Uluhlu olufutshane luhamba ngolu hlobo lulandelayo:

1. Ubudlelwane phakathi kwesantya se-crankshaft kunye nesantya se-camshaft ngokuqhelekileyo yi-2: 1, isantya se-crankshaft yi-6000rpm, kwaye isantya se-camshaft yi-3000rpm kuphela;

2. Iimeko zokusebenza ze-crankshaft zimbi nakakhulu. I-crankshaft idinga ukwamkela amandla ahanjiswe yintshukumo ephindaphindiweyo yepiston, iguqule ibe yi-torque, kwaye iqhube isithuthi ukuba sihambe. I-camshaft iqhutywa yi-crankshaft kwaye iqhube ivalve ukuvula nokuvala. Amandla ahlukile.

3. Ijenali yecrankshaft ineepads ezithwele, kwaye ijenali yecamshaft ayinazo iibearing pads; Ucoceko phakathi kwejenali yecrankshaft kunye nomngxuma ngokuqhelekileyo mncinci kunalowo wejenali yecamshaft kunye nomngxuma. Kwakhona kunokubonwa ukuba imeko yejenali yecrankshaft imbi kakhulu.

Ngoko ke, kuyaqondakala ukuba i-crankshaft igugile kakhulu kwaye ijenali ye-camshaft igugile kancinci.

Ngenxa yokuba andizange ndibone nayiphi na imifanekiso ye-serious wear, ndiyakwazi ukuthetha ngokufutshane ngezizathu ezinokwenzeka. Ngokomzekelo, i-coaxiality ye-cap ye-bearing cap ayilungile, okukhokelela ekugqokeni okungaqhelekanga kwijenali kunye ne-bush ethwele; uxinzelelo lwe-oyile lusezantsi, kwaye akukho filim yeoli yaneleyo kwijenali, enokuthi inxibe ngokungaqhelekanga.
