1st gear/ second gear low ratio has enough lugging power never did engine die or i restarted engine!
In fact i have demonstrated anti stall capability of the engine to few people and they were impressed, Dwarak included. I think i even showed it to Khan. CRDe engine refused to die on steepest of inclines and kept lugging even in third gear low! The engine adjusts the rpm automatically just as much as it is required. Here one gear here n there doesnt matter, the motor pulls in. |
Dear Vinod,
The problem is not engine stalling on slopes. In our old jeeps when we need to negotiate boulders, we put it in first low and can crawl over without abc extremely slowly.
In the thar we felt that she crawled very fast in these situations. To slow down the crawl speed, if one tapped the brakes, she stalled.
Sometimes she could not climb certain boulders and we needed to raise the rpm above 1800 which gave us a lot of power and the use of clutch was required to slow her down.
Next time you see a big enough rock, please try this:
- First, no ABC to get to the top of the boulder. (won't happen IMO)
- Then press the accelerator slightly and try to control thrust without clutch (difficult). This is why we made the statement: One needs to relearn their offroading techniques (especially for old school jeepers). Newbies will have it easier IMO.
- While crawling mid way on the boulder towards the crest, try to control speed by tapping brakes (no clutch). She will start shuddering and will try to fight back by increasing rpm and car becomes faster (read unmanageable) or she will stall.
Please do these three things when you get the car next time and get back to us with your unbiased non company opinion.
By "unmanageable" i mean the minutest of control that's required to negotiate a boulder strewn area where you scale a boulder from one side but on reaching the crest, you may have to turn the steering to exit from another side for example.
Yes, i agree that she effortlessly climbs slopes even with stock tyres where traction is not too much of a problem. Problems are for rock crawling and faster descent rate.
Can you guys please put up the torque delivery charts. At what rpm does the torque curve start moving linear and when does it max? I'm sure you must have it.
I'm also waiting for someone to answer why the squeak was happening. If not one from either three of you have bothered to find out why, it's shocking since you guys are petrol/dieselheads and if you are not bothered one can't expect anyone else from the company to bother! Please please let us know.
EDIT:
I had asked another query to BD a long time ago. Is it possible to go to 4.88 or 5.38 in the Thar? Especially if one has fit bigger tyres, the car will still go faster in crawl. He said no, max to 4.5. Why not higher? Why are these queries not being answered ''scientifically" with a reason?
