...Kapag malamig, malamig din ang cylinder. So this has the effect of reducing the temperature of the compressed air, which might result in hard starts. Thus, heater plugs are used to compensate...

ehem, maka-sabat lang po konti.
di po lahat ng diesels may heater/glow plug. yan po kasi mga engines ng cars nyo, remember designed yan ng japan for cold climates. pang-japan, US or europe na market. malamig po sa kanila kaya may glow plugs yan. now since mga diesel cars sa pinas ay cbu ang engine galing japan, di na pagaksayahan ng hapon na baguhin pa ang design ng engine nila para lang maging cute ang dating sa mga pinoy. napakaliit ng market dyan para gawin nila yun. saka malamig na din naman bandang ilocos at mountain province.
pag ang diesel engine po ay designed for tropical climates, walang glow plugs yan. yung mga nasa malaysia, indonesia, thailand kung saan gawa sa kanila yung mga engines nila, walang glow plugs yan.
saka depende din yan sa compression ratio. kung mataas ang ratio like 20+:1 kahit walang glow plug yan aandar yan. kahit malamig.
yun nga lang ang diesel ay nagiging parang gulaman pag winter kaya ang diesel trucks sa temperate climates may fuel heater.

October 6th, 2003 12:41 AM #13Yebo, kahit mainit panahon hirap start diesel kapag completely cooled down ang engine. MB100's for example. try removing the relay for the heater. ayaw talaga mag start ang punieta

October 6th, 2003 09:49 AM #14My ride is using a 4jb1 surplus engine, with glow plug. Pero di ko kinabit ang wiring ng glow plug/heater. Andar siya agad anytime kahit sa umaga.

May naalala akong owner ng bagong Revo diesel, akala nya direct injection ang makina nya kaya pihit kaagad ang starter nya. Nagi-start naman dahil siguro bago pa at mataas pa ang compression, pero I advised him to let the glow plug do its work. Tinuro ko yung indicator sa dash para malaman nya na maiinit na at pwede na i-start.

I second da moshon your honor!! :D
wala ngang glow plug ang crosswind and it's siblings or big brothers (fuego, trooper, NKR, elf trucks)
malamang nga sa cold climate lang. para i-improve yung flow ng fuel pag malamig at i-preheat na rin yung fuel bago pumasok sa pre-combustion chamber ng makina.
4jb1 is fuegos 2.8 engine.

October 6th, 2003 01:01 PM #18All functions in a modern diesel engine are controlled by the ECM communicating with an elaborate set of sensors measuring everything from R.P.M. to engine coolant and oil temperatures and even engine position (i.e. T.D.C.). Glow plugs are rarely used today on larger engines. The ECM senses ambient air temperature and retards the timing of the engine in cold weather so the injector sprays the fuel at a later time. The air in the cylinder is compressed more, creating more heat, which aids in starting.
Smaller engines and engines that do not have such advanced computer control use glow plugs to solve the cold-starting problem.
Hope this helps.................... saka po pala lahat ng diesel engines DI........:-)

baket yung MB wagon ko 21:1 ang ratio.. hirap pa rin mapaandar ng walang glowplug....??

I wish Doc Diesel were around to back me up... di ko to specialty to
anyways, to answer some of the questions f Mr. Bubbles and the others.. at magkaron ng konting kalinawan, please read the following links.

simply put, a direct inject engine doesn't need glow plugs because fuel is directly injected into the cylinder. it relies solely on the compressed hot air to ignite.
yun lang muna at di ko expertise to. let's wait for engine experts to give their answers.
basta, I can say with absolute certainty, alang glow plugs ang crosswind. :D
tanungin nyo si Pres Bulldog kung meron yung Fuego nya, 4JB1 makina non, saka yung kay Secreatry tebs, his Isuzu MU. 4JB1 din ata makina nun.
planning to keep it for 15yrs just done 10,000 km already replaced the transfer case fluid w/...
