Mawdaw engine hta sau htu ai gaw ahkyak ai lit nga ai, madung hku nna lawu na lam ni hku nna:
1. N san seng ai hpe hka ja ai:
Dai sau filter gaw, engine sau kaw na magri n-gun, nhprang wan, n-gun n-gun, colloid, hka, carbon n-gun, n-gun n-gun n-gun ni hpe atsawm sha shapraw kau ya ai majaw, sau san seng ai hpe hkam la lu ai.
2. Engine hpe makawp maga ai lam:
San seng ai sau jaw ai hku nna, sau htu ai jak gaw, engine kata na arung arai ni (crankshaft, matut mahkai n-gang, camshaft, supercharger, piston ring zawn re ai) ni hta n san seng ai lam ni hpe n hkra hkra makawp maga ya ai majaw, dai arung arai ni a prat hpe galu kaba shangun ai.
3. Sau a prat hpe jat ya ai:
N san seng ai lam n nga ai sha hka ja da ai sau gaw, shawng na sau chya ai, katsi ai, san seng ai atsam ni hpe naw tawn da ya ai majaw, sau a prat hpe grau galu shangun ai.
4. Garan ginhka ai lam hte hkrang shapraw ai lam:
Sau hka htung ni hpe full-flow (sh) split-flow amyu hku nna garan ginhka da ai. Full-flow filter hpe sau pump hte sau htu ai shara kaba lapran hta series hku matut da nna, htu ai shara de shang wa ai sau yawng hpe htu shapraw ya ai. Maga mi de, diverter filter gaw, sau htu ai shara kaba hte parallel hku matut nna, sau pump kaw na pru wa ai sau daw hpe sha htu shapraw ya ai.
Sau hka htung hta, hka htung laika pa, nta langai, hte karum shingtau ai arung arai ni rai nga ai, seal, support spring, bypass valve ni lawm ai. Bypass valve gaw, grai n san seng ai majaw, filter paper hkrat sum mat yang, sau hpe engine kata de naw lwi shangun lu hkra galaw ya ai.
