HINO's are there.. Turboed, Electronically controlleed injections,
AL's are there 12L+ displacement,
412 cu.in series, turboed, electronic Injections

WEll Do have a look at the website.. It won't be boring I promise..

Hey its never boring. Keep it coming, it will actually add a lot of value.

Interested to know how local drivers describe turbo lag.

Is it true??
Directinjection, jomz....any clue??

Nitruos bhai... No idea about TATA's...
410??? Wanna be a guinea pig??... A sincere advise being a friend.. Don't try anything New in a commercial vehicle market... chances of it meeting expectations out are 50/50...

The seccond iteration of any vehicle Will be much beter than the first... after getting all the market feedback and sorting out the issues.. But if you buy a new one... You'll be the unfortunate guy giving the feedbacks.. :-)

But, aren't manufacturers guided by validation rules, which they test during prototyping? I guess its those validation rules that are not truly simulating the real world conditions. Big Turbo Lag in a load hauler expected to run in the City is a big no-no.

However, I also recall a very rare minibus ride in Kolkata on a 407 turbo chassis and the driver was going up the gears unnecessarily, incidentally a Tata Service person was taking a ride in the same bus and he went to the driver and scolded him for not "using" the gears to accelerate (which is quite right, there are speed ranges each gear is supposed to be used at). I guess the "drivers" of most vehicles cant differentiate a petrol engine from a Diesel one, let alone a TC engine from a NA one. So a big question then is that "driver" education holds a huge key even in the technical aspects of running a vehicle.

.

yes validation rules are there... and they test during prototyping.. but in the indian commercial vehicle scene... no rules match the abuse those trucks take...

Hi,

Found this site very interesting:
Auto.in - In Association with AutoIndia.com

They are engaged in bidding of Commercial Vehicles and Cars. Interestingly, there are quite a few models listed too, for bidding. Just thought whether it may be of some use to Nitrous or those who own CVs.

Can you please throw some light on the AL engines?

These are actually engines designed by British Leyland, right? Did AL do some redesigning on them like Tata Motors did on the original Mercedes engines?

Wasn't 412 the engine fitted on Comet and Viking series in the seventies and eighties? It developed 110 HP @ 2600 RPM if I remember correctly (compared to 112 HP @ 2800 RPM developed by Tata's 692 that equipped the 1210). What was 412's capacity in litres/CC?

Presently, all engines of AL are HINOs (a toyota group).
So, Jap power,baby!!!

Hippo and beaver use 680..
In l it will be 680*.25*.25*.25=10.65L
412 = 412*.25*.25*.25=6.435L

412's are still avalable as industrail engines for Gensets.. please chheck the Genset and marine Engine section of the ashokleyland website for details.Lemme search the link..

Yeah in the ashokleyland website.. In tractor trailers 3516H/AL has a model which is still driven by 412
3516AL.. 412 was turbo charged and intercooled..

[Jomz]

In the same website, section - special vehicles.. Check the hippo series for specifications of 680 engine....

[nitrous]

All those numbers remind me of muscle car V8 engines.
504, 524, 440....

So 412 is 6435 CC. The Hino engine that AL uses is also about 6 litres but much smaller than 412 in terms of dimensions. What is the reason for the difference in size? Wasn't 412 used in Comet and Viking earlier?

In terms of size, power, performance and probably even life, I don't think the Hino engine differs much from the Cummins B 5.9 that Tata uses. But perhaps Hino is slightly more fuel efficient. What say?

Hino has around 0.5L lesser displacement than 412.. Which explains the change in the size...

Cummins entered recently right.. around 5 years back...

Keep in mind that displacement is not the only thing which decides, size, power. performance and life...

for example why does a ford 1.3 L rocam Engine produces lesser power than a Suzuki 1.3L esteem Engine??

the jap engine in the above example has higher life, more power and is more fuel efficient.I believe itz the japanese Technology which makes the difference.....

The British Leyland connection ended in 1980 I think, and Ashok Leyland has been accessing Hino technology since the early 80s. Now looks like AL is the real Leyland.
