DISCUSSION - What is RPM?

recently this is quite a good topic that i wanna ask
What is RPM xcelly?
how it's work?
n how do we know the RPM is ok or not?
so far when i drive the RPM meter show at number 3. is't ok?
please advice

RPM is rotation per minutes...
Some people refer its as Tachometer...
Drive section of ur engine which is crankshaft is measured to rotation per minutes,
ur engine increases in RPM until it get's to maximum RPM as u accelerate,
this maximum limit is called the red line as for myvi 7-8,
this is the limit where u can rev ur engine safely,
after that you need to shift to a larger gear ratio....
then repeat the process.....

no 3 should be ok....
when idle rpm should be at 0.7 - 0.8 wihtout aircond...

acctually what's the function the second tachometer...?

second tachometer with blinking light u mean?
that one for shifting gear at a certain RPM with help of blinking light..
hahaha...
that one need to set when to blinking,
blinking as a marking to shift gear at a right time of speed range for engine produces maximum torque

this one im not too sure...
better ask Ezd...
his previous satria full with meter.....

OIC
yes..the "blinking tachometer"..hehehehe..tq shamin

aip
but when i did't open the accond the RPM also at number 3
how???

always at number 3 only????
RPM meter moving or not???
when start engines in early morning it takes time before the RPM can go down to 0.8....

when i start the engine of course it moving
but when i drive seems it statik to number 3
how?
normal or un normal?

RPM move with ur speed ..its normal when u at 70km/hour RPM show 3...but its abnormal when ur car not move but ur RPM show 3...

as far as i can remember first time i got that car the RPM just at number 2
now it keep coming up.
why??
i think it does't metters but just for my info only

if manual transmission 2.5 should be at 90kmh....
3 must be around 100-110 at 5th gear...

what do u mean by coming up?

wani: i think maybe at st time u drive slowly and now you increase your accelerate..kidding..Maybe u need to warm up your car 1st before drive it in the morning

hehehe..i think u must rev ur car till red line..hahahaha...

do we actually need to rev the engine till the redline every day? if not how often? I never rev my car until redline except when driving on the road.

not every day...once a week is enough...rev till red line while driving on the road?
r u drifter??hehehe...

please dont do it on the road haha

ehmm i warm up my car every day early morning at least 5 min
coming up means before this the RPM number just at number 2 but not always at number 3. That make me wonder why...
i always drive about 80/90 kmj xcept going back my hometown 100/110 kmj
does't effect the RPM?

RPM n engine what is the relationship ek?

they r like brothers and sisters else nephews but i dont know how to describe it sorry...


RPM number just at number 2 but not always at number 3

i think ur car become matured...

hahaha i think so
but just for the info to myself kan wanna know about this
forget to ask
IF the rpm number is going to number 8
how is't ek?

rev to 8... try if u really want to know...
anyway wani did u change ur rim??

FYI,
Shift gears between 2 and 2.5 RPM for optimal engine efficiency.
Allowing the RPM to go up to 3 RPM or higher increases speed but makes the engine work harder, which reduces fuel economy.

If u rev to 8, its mean u over-revving the engine which might causes damages and may cause oil to leak onto a hot exhaust causing a fire.

RPM is stand for rotation per minutes..
mm..rotation ur cyling injin..
rotation of piston moving..
correct me if im wrong..
hehehe....

wahhh so hebat one arrr if going to 8
don wanna try arr love my kodok more than testing the RPM

p/s --> me still waiting my bf to change my rim myb for my bday present...hahaha

I mean, on the highway, sometimes when i'm trying to overtake other vehicles the RPM meter went very high almost to the redline, especially when I press the OD button. FYI I'm using auto transmission.

The higher the RPM meter goes will cost more fuel consumption, correct? to save petrol just drive below 90km/j (RPM below 3)
