Back on topic, this 3cyl engine sounds great and if it’s really +15% fuel economy, I’ll buy a 1er with this engine.

Having said that, E84 still looks better than this lol

For the rest of the ppl reading this blog, click on this link, to understand engine operations and why diesels have better torque for the same NA capacity than petrol. ( paragraph 4 )

Since all diesels are turbocharged nowadays, there is another reason why it has more torque is, during the compression cycle, only air is compressed. Hence you can boost the shit out of it preignition doesnt kick in.

Man. That simply shows one thing. You don’t know much about engineering at all.
The whole engine is built on the principles of thermodynamics. Work cycle, diesel cycle, Otto cycle, atkinson cycle. Work done by expanding gases, torque, moment, gas equations, etc.

Its ok. I won’t debate with you, as debating with you means having to go back to basic form 4 physics, building slowing to advanced thermodynamics and engine building. A knowledge which took me 4 years in Uni to obtain. ALthough i don’t deal with engines in my line of work for 8 years, thermodynamics is an integral part of my work.

No worries. Just believe what you believe. I have no issues with that. I only give explanation, not free education.

“High compression ratio means longer engine stroke.” WRONG!

“Longer stroke means longer crank.” WRONG!

Thermodynamics? What has any of the above statements got to do with thermodynamics? Moron…

Tell me, if u work and live in france, do you think your employer will pay u in Ringgit?

RM 6.5 is about 1.6 euros. Average income there is 30000-40000 euros per year.
Cars are about 10k euros-20k euros.. Rental is about 200-400 euros per room per month. Decent meals can be had for 5 euros. ( I worked in europe for a few years )

Back to malaysia. Diesel is RM 1.8. Average income is RM30000 or less. Cars how much?
Rental is about RM 500 per room per month. A decent meal costs about RM5-10

And cost of living and buying power? Don’t forget Euro is still a stronger currency compared to Ringgit despite massive problems with their banks.

SO unless you get shafted by your employer earning Ringgit while working and living in France, i suggest you keep such comparisons to yourself, as it simply makes u look like a katak bawah tempurung.

You are quite thick.

Both of your post where u disagree with me, what you are saying to counter my point, is exactly the same shit as i was saying, but worded differently. And this one is especially good, i said tax rate is about the same, and u mentioned about local tax rate.

Are you thick or what?

I wonder how much you know about thermodynamics before u refute my points.

I would actually agree. I drive a Perodua Viva with the 1 litre 3 cylinder engine and Mercedes 190e with a 2.6 litre 6 cylinder engine.

The Viva’s engine does growl deeper than say a Myvi, and I thought it was just the lack of sound proof.

But since its a basic engine, it does vibrate a bit during idle compared to a 4 cylinder.

Nice information to know

Diesel engines are torquier simply because diesel has more energy per litre than petrol.

The higher compression ratio is simply due to the fact that diesel combusts at high compression without the need for spark plugs.

Diesel, although has more latent energy, takes a longer time to combust through each stroke, hence they can’t rev very high. To take advantage of that huge but slower explosive torque, engineers design diesel engines with longer strokes to harness that torque and make it more efficient, thus you get the undersquare/long stroke config.

Most petrol cars are done oversquare/short stroke simply because petrol engines (NA) are dogs at low revs. If petrol were more efficient the engineers would’ve used an undersquare config. Larger displacement petrol engines may be designed undersquare, but it all depends on what they’re hauling…

Cheers.

Same goes for most Mercs and Audis.

I strongly believe the speakers inside the car is used to generate precise timed sounds to offset the lost harmonics of 3 missing cylinders ( 6 vs 3 ). If noise cancellation headset can work, i don’t think that is beyond the realm of current technology.

This technology is already deployed in the new M5 if im not mistaken.

While i respect the effort taken by BMW/Merc to downsize, but Im concerned that they will take it too far. What’s next? 1 cylinder car?

Just like the HP wars in the early 2000s. Very few ppl would need a car that makes more than 300hp, but BMW/MErc/Audi make them anyway until the point where you get 500-600hp cars that you just cant get enough traction to put those power down.

High compression ratio means longer engine stroke. Longer stroke means longer crank. Longer crank means a better torque due to simple mechanical advantage or sacrificing speed for force.

Imagine a bicycle. Diesel engines have longer pedals and because it has longer pedals, the up down motion of your legs are longer as well ( longer stroke, more compression ). And because it has longer pedals, the torque generated when you pedal with the same pedaling force is higher due to simple mechanical advantage.

Got it guys?

They earn a lot more. And our income tax aint that low. The reason our tax is low is because our earnings are low. Earn the same amount as them after conversion and the tax comes to be about the same.

Hopefully the electronic control dont rosak.

if rosak, the mechanic will scratch his head till botak to solve this prob.

I am fine with both methods, though I do admire the tiny high performance engines.

To be honest I can understand why they don’t want to bring this one in. It is UGLY. In a country where beauty is very important that is not a good idea. The only thing that can safe it here is the BMW badge, but will that be enough?
