Ntxiv nrog rau cov khoom tseem ceeb, lub cav yuav tsum muaj ntau lub tshuab pabcuam ua haujlwm.
Cov no feem ntau suav nrog cov kab hluav taws xob (uas feem ntau muaj lub turbocharger los txhim kho qhov siab - qhov siab ua haujlwm, nce siab), roj system, qhov hluav taws xob hluav taws xob (feem ntau suav nrog -voltage magneto, cov kab hluav taws xob, thiab cov hluav taws xob), qhov pib (feem ntau yog lub tshuab hluav taws xob), lub tshuab ua kom txias, thiab lub tshuab lubrication.
Lub caij no, nrog rau kev txhim kho tas mus li thiab kev nce qib ntawm cov tshuab hluav taws xob sab hauv hluav taws xob, kev ua haujlwm ntawm pistons yog tas li nce. Yog li ntawd, yav tom ntej piston tsim thiab kev tsim khoom yuav ntsib cov teeb meem ntau dua thiab muaj cib fim.
