heres a nifty link for those people who don't know how the diesel engine works.

heres another link for the gasoline engine.

yup, i already read the info there before, but i still can't imagine how air can be compressed to such an extent that it can ignite diesel fuel even without a spark plug. yung glow plugs naman, pang pre-heat lang diba, hindi sya ginagamit sa actual combustion ng fuel? can anyone please explain this feature of diesel engines in greater detail, pls, pls pls.

when the air becomes compressed it becomes very hot, fuel oil is then sprayed into the cylinder where it ignites spontaneously on meeting the hot air.
yan lang po ang alam ko e... hope it helps. :wink:

banging of atoms siguro ang effect... the more you compress, the more they bang up at each other generating heat/energy.. hence the explosion.. then again.. what do i know about molecules.. tinulugan ko ata chem class ko eh. eheheh

PV=nRT
eto alam kong relation ng P-pressure, V-volume, T-temperature
so the higer the pressure, the higher will be the temperature, thus igniting the diesel fuel.
ps: correct me if i'm wrong

di ko pa rin masyadong maintindihan yung diesel engine. i need someone who can explain it to me.:mrgreen::mrgreen::mrgreen::mrgreen:

samahan nyo na kaya ng discussion ng thermodynamics para mas malinaw :lol: :lol:
tama lahat explanation, pero ang gustong explanation yung kay HBOY. the more you compress, the more the atoms "bang" each other :mrgreen: kaya sila nag-iinit errrrr.. they generate more heat :P
malinaw na ba? :wink:

you will also notice that the compression ratio of diesel engines are much higher than gasoline engines. gas engines don't need very hot air to burn the gasoline, they have spark plugs that will do the igniting. the air is just needed for the gasoline to burn.Signature

when you say higher?.. the lower the figure the higher the comp?.. naguguluhan ako eh.. lets say.. 8:1 vs 12:1.. by looking at the figure 8:1 compression is lower unless meron na naman nagbabaligtad nito... wherein some cases the higher the number.. the lower the significance... ewan!...
sir rsnald,
ah eh.. oo.. nagiinit nga!..mwhaa....ibang banging naman yan!.. ehehe..
that may be, but we all got plastic, young and old. we asked the lto guy, "papel ba po, o...
