Uma sikhuluma ngama-pistons emoto, kufanele sikhulume ngomkhuba wokungqongqoza kwepiston. Lokhu okunye kokuhluleka kwezimoto okuvamile. Uyazi ukuthi ungakuxazulula kanjani ukwehluleka okunjalo?
Ngaphambi kokuxazulula inkinga yokungqongqoza kwepiston, kufanele siqale siqonde ukuthi yini ebangela lesi simo.

◆Igebe phakathi kwepiston nodonga lwesilinda likhulu kakhulu.

Ngemva kokugijima isikhathi esithile, isiketi se-piston nesilinda kuzobe kugqokwe kakhulu, kubangele ukuphuma okungathí sina futhi kushaye isilinda.

◆Izinduku zokuxhuma ngazinye zikhubazekile ngenxa yezizathu ezihlukahlukene, okubangela ukuba i-piston iguge, igebe liba likhulu futhi isilinda siyashaywa. I-piston knocking izodala ukusetshenziswa kukaphethiloli kwenjini ngokweqile, ukuvuza kukawoyela wenjini, ukusetshenziswa kakhulu kukawoyela, kanye nomnotho ongemuhle. Lapho ipiston ishaya isilinda kanzima, ipiston izophuka futhi isilinda sonakale. Ngenxa yalokho, induku yokuxhuma izophuka futhi i-cylinder block izolimala.

Ngemuva kokuthi injini isisebenze isikhathi eside, i-cylinder piston iyaguga. Ngaphezu kokugcotshwa okungekuhle, igebe elihambisanayo phakathi kwepiston nesilinda liyakhula ngenxa yokuguga, futhi isinyathelo esibucayi sivela kancane ngaphansi kwendandatho yokuqala yegesi, okubangela ukuba ipiston ishaye isilinda. Yenza umsindo ongajwayelekile.

Kulula ukuxazulula inkinga uma uqonda isizathu:

◆Uma kunomsindo ongqongqozayo osobala lapho izinga lokushisa lenjini lijwayelekile, zama ukugwema ukusebenza ngesivinini esikhulu futhi uyiqaqe futhi uyilungise ngokushesha ngangokunokwenzeka.

Ngemva kokukhipha ikhanda le-cylinder nokukhipha ipiston, kutholakala ukuthi isilinda siphume kakhulu nxazonke, sicindezelekile, noma igebe phakathi kwepiston nesilinda likhulu kakhulu. Shintshanisa i-cylinder liner, i-piston neringi ye-piston.

◆Uma induku yokuxhuma itholakala ukuthi ikhubazekile, kufanele ishintshwe ngangokunokwenzeka.

Ngemuva kokuthi injini iqalisiwe, kuzwakala umsindo oshayayo ngesikhathi sokusebenza kwezinga lokushisa eliphansi. Lapho izinga lokushisa livamile, umsindo uyanyamalala, ngakho ungawushiya wedwa.
