another query... with a piston stroke that long, at 103rpm arent you exceeding 20m/s piston speed making the engine unstable?
98" Stroke

Piston travels 98"x2=196" per 1rpm

196"= 4.98m

103rpm x 4.98m = 512.94m / minute

512.94 / 60 = 8.54 m/s

Correct?

R, you are right.

You can run it on petrol (and you don't have to fit a welding machine for ignition) but it is not used because economics does not allow it.

Like Karthik said, we've already seen it. But if by posting it in this section you are implying that a motorbike could perhaps be powered by this then...

Wink Thanks GTO!

See! This is what I like about T-BHP.

I've been moaning & griping all over the forum about the lack of bottom end in my Lancer, & GTO, darling that he is, goes & starts a topic on it offering a solution!

Thanks man!

I may have to enlist Viper's services, though, as I'm not too sure it would clear the bonnet. Any idea if my K&N would work with it?

Later...

most of these engines run on oil ,not on diesel .The Rpm mayt exceed 500 and the wartsila engine might be doing a max of 200-300 i guess .

For rpm and power range, one can refer to this site.
http://www.wartsila.com/Wartsila/doc...rta_series.pdf

These engine can operate from as low as little above 60 rpm. Interesting - like a second hand of clock ticking!!!

Another high power - slow speed engine maker

This engine consumes around 14000 lts of fuel in one hour at full power. If we assume that average people consume around 100 lts of diesel in a month, it amounts to 140 months or nearly 12 years of fuel!!!
The fuel used can have a density of 1010 kg/m3 that is heavier than water.
The fuel specs says that the pour point should be less than 30 deg Celsius. In most of the Indian cities the oil would not flow at night. Something like tar!!!
The cooling water in the system may be 10,000 lts and if lube has to be changed, then it would amount to around 40,000 lts in one go!!! Well here it is never changed
