Gasoline vs Diesel Engines [Merged]

[manong]

baket mas maingay and mas ma-vibrate ang diesel engine compared

sa gasoline engine?

[boybi]

kundi po ako nagkakamali, dahil po sa mas mataas na compression ratio ng diesel engines compared sa gasoline engines.

[roydok]

Yup, it's due the high compression which results to very high pressure that is needed to ignite the diesel fuel.

[ephraim]

A gasoline engine compresses at a ratio of 8:1 to 12:1, while a diesel engine compresses at a ratio of 14:1 to as high as 25:1.

[ephraim]

Also, diesel fuel has a higher energy density than gasoline. On average, 1 gallon (3.8 L) of diesel fuel contains approximately 155x106 joules (147,000 BTU), while 1 gallon of gasoline contains 132x106 joules (125,000 BTU).

[boybi]

gestapo, di ba ang joules/BTU is unit of energy? hindi ata density. pasensya na kung mali ako, baka nangangalawang na utak ko sa physics/thermodynamics.

[ephraim]

oo nga. unit of energy yung joules/BTU. sa pagkakaintindi ko, (sori po kung mali ako. bata lang po ako. :mrgreen masmalakas ang energy na na-e-exert ng diesel fuel kaysa sa gas.

[Dieseler]

And from the way diesel works, it is around 30% more efficient than gasoline engines.

[OTEP]

And diesel fuel is more environment friendly to produce.

[manong]

compression ratio lang ba talga?i mean...bat yng ibang gas fed engine kahit high compression considering same displacement e mas tahimik? F1 engines perhaps...LOL

[ephraim]

yung diesel fuel higher ang energy density niya kaysa gas.

[boybi]

compression ratio lang ba talga?i mean...bat yng ibang gas fed engine kahit high compression considering same displacement e mas tahimik? F1 engines perhaps...LOL

mataas na po ang 12:1 compression ratio ng gasoline engines as compared to the minimum 16:1 ng diesel engines. don't have any ideas on F1 engines. also, the higher torque output of diesel engines also adds to the vibration and noise, mas matapang ang diesel engines :evil: sa gas fed engines.

ito, tignan mo itong link na ito. sana po makasagot ito sa mga tanong mo.:D:D:D

ito rin po, isang link para sa gas engines.

diba si Shaq tawag sa kanya "Shaq Diesel"... hmmmm whats the explanation for this?

hindi kaya dahil malakas siya at parang truck!?! :lol::lol::lol:

[me_jake13]

just wanna know what u guys prefer more, gas o diesel? based on performance, consumption, etc...

[GlennSter]

ibang iba ang diesel sa gas in terms of performance and comfort.

sa gas ako hands down.

pero ibang usapan na kasi ang presyo ng gasolina dito sa atin.so the more practical choice is the diesel.

and please use the search function.there are several discussions na about gas versus diesel engines.

thanks!

[karlbo]

wala me masabi sa gas... ive been a user since nagkasasakyan ako.. pero now that the prices are all going up... and medyo nagkakainterest na rin sa trailing.. hmm... i thing diesel na ko next time... nyahahahah :D

[mbt]

for the road, gas pa rin ako. tough to beat the responsiveness of a gas engine... well, unless you're talking about the latest crop of BMW turbodiesels hehehe

off the road, diesel nalang.

[27th_Faktory]

i always dream about having ang FORD explorer na desiel....hehehehehe

thats it mahal kasi yun gas ngayon

[Bogeyman]

I chose diesel, for one VERY compelling reason: nasa Pilipinas tayo eh. I can't exactly take advantage of gasoline's acceleration in the face of rough roads, horrible traffic and rising gas prices. An airport runway is about the only place left that's ideal for gasoline.

Diesel: power>speed. 'Nuff said.
