I-valve yokuphepha yemoto yokuhamba ivuza uwoyela. Uma i-valve yokuphepha ivuza uwoyela, ingcindezi ngaphakathi kohlelo izoba ngaphansi kakhulu, okwenza ijubane lokujikeleza lemoto yokuhamba linganele futhi ngenxa yalokho okuholela ekuphambukeni kokuhamba. Indlela yokuxazulula inkinga yilena: buyisela i-valve elonakalisiwe yemoto yokuhamba; Lapho wenza isinqumo, ama-motor ahamba ngakwesobunxele nangakwesokudla angashintshwa ngokuphepha ukuze abone ukuthi ngabe ahlambalaza lapho ehamba ngakolunye uhlangothi.
