Guide: How To Drive and Maintain a Diesel Car?

[nozzlering]

Thanks a lot buddy,I got my doubt completely clarified.It looks like you are some automobile engineer..right?

As I have already mentioned,this is not a thread,instead this is a school where we are learning a lot(I request mods to make it a sticky).The concept of torque steer is now clear..let's move ahead with another issues..

Okay buddy you said that one shaft is long and another is short,but then front wheels can turn in both the directions,now when they turn towards the direction of the longer shaft then won't they result in excessive torque steer?
Secondly:Why it is so that in 4WD vehicles torque steer is lesser than others?

Thirdly:Can't the traction control help here?

I am a marine engineer. So I know a little of all. And apart from being a profession, it has been my passion to learn more about engines. I have worked on huge diesel engines 4 stroke and 2 stroke (Very less of us would be knowing that the mighty ships are hauled by 2 stroke diesel engines!!!!).
Back to your question,
1. Now FWD (and AWD) vehicles come with equal axles, so torque steer phenomenon is reduced to a great extent.
2. And if there happens to be a case of unequal axles, the longer one will be made more stiffer than the shorter one. Stiffness can be increased by increasing the dia of the shaft. This way torque steer will be eliminated (*conditions apply). If the driver is heavy footed, torque steer will be experienced. And if traction is loose, all the cars will feel it.

I cant say much about your second question.
Maybe,
In 2WD, excess torque is lost in way of torque steer.
But in 4WD, the available torque is distributed to all 4 wheels. So no excess torque to be wasted. I guess so. Not sure.

Where is guide. need to go through it.
Thanks in Advance.

Start from page 1. Read on upto this page.

Drive a mEagle and you will really praise the top end of this engine.In fact I feel its the best diesel engine and the only with such high-revving but still great power delivery characteristic.Only issue is that the engine hasn't got the car it deserves.


Either you made a typo or you have driven a Manza petrol,because diesel Manza can never cross even 5k mark,then 6-7k is a talk of far things..

i dont know man. i remember it going past 5K RPM. and it was diesel manza for sure.

Diesel Manza can cross 5000 mark. But once they pass 5000, the needle turns red in colour (will post a pic of it soon). So never ever tried beyond 5000. I dont think it can go to 7000.

 

[type-r]

yes yes the needle turned red. i am having doubts on myself now whether it actually touched 7000. but surely it went past 5000 and boy it was climbing the speedo. i was in 5th doing aroud 2.5K RPM and was touching 150+. my respect for the Manza's quadrajet engine just got raised to a whole new level then and there.

I tried to push my Xylo the same way but i could take it to 110 max. After 110, the climb is quite drastically slow. actually pace starts to drop after 80 already.

that was because yours was a d2 . try the E version and get amazed.

i know it is the engine at fault. but hey in a country which only asks,"kitni deti hai?", this engine is perfect! hahaha

I can't believe it.150+ in 2.5k rpm.By this way Manza will do 250+ in 4.5-5k rpm range...
even my Corolla don't do such speeds at such low rpm in even 6th gear.And then Manza does not go over 165-170(I did till 165),so how is it possible.
Get the tachometer of the car checked buddy.BTW,in the top gear,Manza can't even touch 5k rpm.There is enough load on engine to stop it from touching such high revs.

So what do you expect from a 75 hp producing engine with a 1500kg body shell?

+1000,mEagle is a fantastic engine(I am a fan of this engine,simply the best diesel engine in my views)

I have a query in Renault pulse the SA told me put the car in 5 gear and at speed of 40 he told me to remove my leg from the throttle and believe me the car kept moving at that speed without any input from me for 4 to 5 kms why so ?

Meagle is better or mhawk ? And why ?

Short geared rations along with the heavy cylinder heads used in diesel give good torque at low rpms,

also possible tuning on test drive cars can be made a bit rich to impress customers,they dont have to prove its giving mileage when it comes to test drive cars,but a turn off in that car was no ABS even wen airbags are offered ,the same with the Micra as both are same cars,
also if car is in warm up phase meaning you just started it a few min back then car will be running rich so amount of fuel running into the cylinder is more than usual,its like the choke people use to pull in the old cars but its automatic now

I think what he have said may be like he was driving in the fifth gear at 2500 rpm and then he was able to accelerate the car and it was able reach 150+.Correct me if I am wrong.

Manza has the 1.3 MJD VGT which is 90 hp approximately.

I would say mHawk is better because -

1) It is a more advanced engine
2) It has an aluminum head
3) It is lighter
4) It has VGT
5) Inspite of being 2.2 litre, it makes more power than the mEagle
6) It is more refined
7) Power delivery is quick and linear

Very very nice thread ! Kudos Raj_5004 for this nice diesel tutorial, and all other diesel enthusiasts thanks for sharing your valuable knowledge... Keep goin...
