hard starting diesel engine

[kkreuk18]

Trabahong remedyo kasi ang ipinagawa mo. Although pede ngang iadvance un timing pero siguradong di din tatagal yan. Medyo mahal at matagal na trabaho ang pagooverhaul ng diesel engine. Mas mabuti pa nga maghanap ka ng surplus, bulungan mo lang un mekaniko nun tindahan na magbibigay ka ng additional para sa kanya para labasan ka ng medyo sariwa pa ng surplus engine. Isang teknik sa pagbili e kunin mo un di nila nilinis, tapos tuyo dapat ang intake at exhaust

This quite an old thread already but one of the things to note here is the risk of doing ' DUKOT' which was adequately describe here.

In a worn engine bore, there in the top end portion of the cylinder is a raised area (compared to the portion of the cylinder below it) called the 'RIDGE'.

The diameter of the cylinder in this area retains it original dimension (it is narrower) because the top compression ring does not reach this area as the piston travels to the TOP DEAD CENTER and so it is not worn.

When you try to remove the piston through the top end of the cylinder the lower edge of the 'ridge' will block the passage of the piston rings, you will have to remove the 'ridge' if you will get the piston out this way.

When you do 'DUKOT' there is a real big risk of the top piston rings in there unworn dimension will hit the ridge with a big force, leaving you a broken piston rings.

Now there are ring sets where the top rings have beveled surface to prevent hitting the ridge, but certified mechanics doesnt really advice to resort to this as they are known to have a poor compression pressure or blow-by sealing.

The thing to do is rebore and fit an oversized pistons/rings or install standard cylinder lining with standard pistons and rings.

To a diesel engine installing an oversized piston/rings is a technique to increase the cylinder capacity and power output of an engine without necessarily resulting to increased fuel consumption because the amount of fuel injected remains the same and fuel is injected only when the air is already compressed.

In gasoline the air/fuel mix is kept around the lambda and enters the cylinder at the same time so using oversized piston/rings will result to increased fuel consumption.

iyong sakin din po hard starting sa morning lang, sabi ng mekaniko eh iadvance daw yung injection pump, tama po ba? hindi ko masyado na gets eh kasi bagohan lang ako.. any advice? when hard starting sa morning black smoke lang ang issue sakin.. thanks po sa advice!!

Hwag na hwag mong ipaadvance ang timing ng makina mo para tumagal ang connecting rod bearings.Masama yan sa diesel fed engines.Daming incompetent mechanic dyan sa atin tsk tsk tsk

ipapacheck ko na lang siguro muna ang glow plugs, at ano pa ipa check ko sir? thanks sa advice!!

+1, merong ibang paraan para maayos yan. Return it to factory pec ewan lang kung hindi yan gumana.

btw, 2LTE diesel turbo pla ang engine, matic..

sabi ng mechanic ko, hindi raw niya iadvance ng isang ngipin yung timing, ireretime niya lang daw yung injection pump.. ano ibig sabihin nun mga sir?? TIA!

Dapat gumamit sya ng diesel timing light o spill method sa pagcheck ng tamang timing ng injection pump.Di maganda kung iguess lang nya.

kng nababana makina nyo dapat ok na. ang prblima ung gumawa ng car mo san lucation mo kc dapat pagawa mo dun sa talagang magaling sa ganyang prblm.kc gayan din naging prblima ng car ng pinsa ko ok na ngaun magaling kc ung gumawa.
