lmgtfy.com/?q=largest 4 cylinder engine in a car

MWM International Motores have some 2.8l diesel what used in Volkswagen LT

Charged or Naturally aspirated?

None

I have a 3.2L Diesel in my van, but I guess it's not really a "car"

Pontiac made a 195 CID(3.2l) inline 4 in the tempest in the early sixties. It was literally half of the 389V8

Fuck 4, the V8 is holy and the straight 8 is mythical

3 liters is pretty big for a non-diesel inline 4.

This.They revved well for that stroke as well.

Came here to post this

just look at 4 cylinder cars around 1910
somewhere between 10 and 28 litres

Porsche did shit loads of work to balance it, right?
It seems so typically Porsche to make something retarded great instead of just working with something easier

>Which 4 cylinder engine is your favorite?

k series. Why would anyone say anything other than k series?

>Why would anyone say anything other than k series?
Because of this.

F20C is better user.

I have a 93 chevy s10, and I'm sure you don't agree its a good car, idk, but man, that car, i fucking love, more than my own life. 75000 miles too. Its just such a beast, it will not quit, my personal favorite

straight 4

I wonder how efficient a v4 engine would be. I don't honestly know any cars that use it right now. I just feel like it would save space, and possibly weight as well.

It is strange how no one uses a v4 in the car world. The closest you get are subarus with their flat 4.

Lancia and their Fulvia had a V4.

Lancia also wanted to put 4 turbochargers on a 4 cylinder, but Group B died before the plans came to fruition. Some user had pictures of it recently, but now I can't find them.
Pic related apparently Lancia's engine for Group S, a planned group for a post Group B world that never came to be.

They are popular in the motorcycle world. Honda use them in the MotoGP and have done for years. Including the king of all V4s, a V"""8"""

Source? I want to learn more of this V4/8

en.wikipedia.org/wiki/Honda_NR500
>The rules at the time allowed up to four combustion chambers so Honda designed a 32-valve V8 with four pairs of linked combustion chambers. This then evolved into an innovative engine with four oval-shaped cylinders. The oval cylinders allowed room for 32 valves and eight spark plugs, the same as that of an eight-cylinder engine while staying within the four-cylinder rules limit.

>Pic related apparently Lancia's engine for Group S, a planned group for a post Group B world that never came to be.

It does exist and it does run.
>that short gearing
>on such a powerful car

I cannot fathom the acceleration.

Oops, forgot link:

If they're on bikes I assume they're weight and space savers. Am I seeing things or is that actually 32 valves?

two additional balancing shafts as I recall.
3 liters is basically a limit for petrol engines,
fulvia had design closer to later vw's VR6 engines (shallow angle, shared single head)
Ford made 60degree V4 (sub 2liter) in 1960-70's, they shared parts with V6 (from 2liters to 2.8) this engine family was called Cologne. They powered german built escorts, capris and some early SAABs.

Yep, 32 valves, 8 spark plugs and 4 pistons. The image is the engine layout

>What is/was the largest (in terms of liters) 4 cylinder engine in a road car?
In terms of diesel, 3.2 is usually the largest you'll commonly find - Mitsubishi's 4M41.

Off the top of my head, the largest commonly seen petrol engines are the Porsche 3.0L noted here , the Toyota 3RZ-FE 2.7L, and the Mitsubishi Astron 2.6L.

For the all-time biggest, you can't go past the Beast of Turin, 28.5L of pure Italian madness.

>which 4 cyl is your favorite
Always been a fan of the Mazda 2.3L mzr disi engine from the first generation ms3's

>3.2 is usually the largest you'll commonly find - Mitsubishi's 4M41
There's actually Mitsubishi 4M series diesels that near 5 litres in capacity, although they're only available with their cab over trucks and buses.

>which 4 cyl is your favorite
Volvo b230

This. A lot of the early cars had HUGE displacement four-bangers.

I'm thinking it would perform similarly to a Subaru flat four since their boxer engine is sort of like a flattened out V4

Can you be this stupid?

>V4

I think 2.5L is pretty big. Considering there are 2.8L V8's.

>Their boxer is sort of like a flattened out V4

Not at all, it's a boxer engine. That's why it's called a boxer.

I have a V4 motorcycle, there's no reason to have one over an I4. They vibrate like an earthquake at high revs

1993
Clio Williams 2.0L 150

F7R engine

>Both bikes retired, Grant crashing out on the first turn after the bike spilled oil onto his rear tire, sliding along with the bike showering sparks, requiring rapid application of powder fire retardant from the race-marshall. Katayama retired on the seventh lap due to ignition problems when running second-last.

Fucking kek

I love my supercharged 2.4L

Best I4 coming through

4BT 3.9L Turbo I4 Diesel.

R8 my I4
me too, 2.3 and kinda slow though. M90?

That airbox is cute

What does the size of the displacement mean?? I drive a 2.5 liter 4-cylinder but i've been noticing that most new 4-cylinders stay below the 2 liter mark, but why?

Mostly because of regulations. In certain countries you get raped with taxes if you go above 2 liters.

There is a general limit as to how large a piston can get, before size and weight concerns of the engine itself outweigh the benefit of NOT adding extra cylinders. I'm sure balance plays a part also, since a four cylinder has different "balancing properties" than say, a six cylinder, which can be balanced for both primary and secondary forces.

>What does the size of the displacement mean??
In layman's terms it's the total amount of volume within the cylinders of the engine, how much air and fuel can displace with the space during the combustion cycle

MAKE WAY YOU PLEBS,

28.4l 4 cylinder engine coming through.

youtu.be/9ooiZeYmYjE

What's the highest RPM like, 500?

Nope K24,

they require two cylinder heads, head gaskets, more cam shafts and gears.

Now put a turbo on it, faggot

the supercharger though?

Biggest 4 I've driven is a 4.9.

help me, fellow four-banger fanatics.
>be me
>have 2015 Ford Focus mk3
>not ST because can't afford
>2.0L 4-cyl naturally aspirated
>want to do exhaust stuff but poorfag, and don't want to spend a lot of money on an SE that could be saved for an ST
>was thinking of cutting out the resonator (circled in red in picture) and replacing with a section of straight pipe
>driving like that for a while to see if it's a noticeable difference
>if it's not loud enough or doesn't good I was thinking i'd put a cheap cherry bomb or thrush glasspack in place of the rear factory muffler
i should be able to do all this for less than $200. any other ideas or better ideas that i'm not thinking of? other options that offer better bang for buck without going full straight pipe brap fart can?

If you're saving up for an ST anyway (which is kinda the message I'm getting from your post) then just don't bother. It's a fine daily, just keep it and maintain it until you can afford that ST.

It will come, user.

Praytell what such a vehicle is

>0mpg

Pretty efficient if done properly.

>Porsche 919 Hybrid's ~500hp V4

...

It's a Comptech supercharger.

V4s have really bad vibration problems and the same problem as any v or flat engine, 2 heads and associated hardware.

Would loveto see them come into the mainstream but I feel the only compaines willing to put in the effort to make them work well and smoothly would be BMW, mercedes, VAG. would be awesome though.

RWD Front Engined V4. could easily have a short wheelbase whilst keeping the entire engine within the wheelbase

5SFe is best 4cylinder

>I feel the only compaines willing to put in the effort to make them work well and smoothly would be
Ford did pretty good in the 60's Good luck finding blocks or god forbid, spare parts for them.

EPA estimated 15gpm

Subaru EJ22

Because it's the only engine thats ever been mine.

god it's so fat.
OHV flat engines are so much slimmer

I dont care. I love all 137 horsepower it makes and you leave me and my BBW alone.

>137 horsepower

>137 horsepower
>EJ22: 2212 cc, 135–280 hp used in the 1989–2001 Subaru Impreza and Subaru Legacy

Could be so much more

that shit looks fun as hell

>they aren't burning 7 liters per cylinder

Pretty shit engine actually but it's still my favorite.

>shower feed injectors
I've never heard of these, whats the benefit?

funny people mentioned diesels right off the bat. VW 1.6 diesel. used in like every mk 1 and mk 2 vw diesel. turbo or na, these thing just kick ass and don't die. they've put on some big miles, and all at around or above 40 mpg. powerful? not really, but enough to do the job... for a really long time

Biggest in a current or recent production vehicle would probably be the 5.2L (317ci) Isuzu 4HK1 diesel four. Used in their cabovers, it makes 205 hp and 440 ft-lbs.

EA63 in my 74' Subaru DL.

1.4litre 8valve OHV boxer. No rev limit and about 37mpg

Also weighs like 60lbs. No joke, I have a spare engine I have in my garage

reminds me of this

better fuel atomisation, air and fuel are in the exact same flow path. I just like them because theyre used in F1

they are also used in Herzegovina
its a fiat kind of thing

>tfw one cylinder has more displacement than a whole LS engine

youtube.com/watch?v=oQMln74M2cU

This. It's completely impossible to get more power out of any current naturally aspirated engine in production cars AND be cost efficient.

Factory stuff is usually well optimized for the price point and even bolt ons that do anything are expensive, plus you would need a custom tune to make the most of any changes.

Also just cutting out the resonator won't do jack shit except make the car louder and maybe even lose a bit of power.

>not a 4AGE blacktop

The cla45 amg has the most powerful production 4 cyl ever made

You guys ever wonder how come all the coolest engines and shit aren't actually in cars?
They're in boats, aeroplanes, trains, and heavy utility vehicles?

Like the weirdest engine we really get is rotaries and even then boats do it better.

Is the Government ruining our fun? Should I just get into ships? I like huge fucking motors, not motors made to be efficient and not try to murder me.

That boat rotary is a custom one-off built by some dude in his garage though, it's not like they're making boatloads of them with that thing.

Yeah but then you got shit like this, that's way cooler than a 4 rotor RX7.

test

3.2 is uncommon but i have seen.
2.4 is relatively common
2 has probably the better end of hp, mpg, weight ratios.

Straight 8 is a unicorn but is less efficient and reliable as the i6.

K1300r. 1300cc i4, 140nm, 174hp, 220kgs, 275kmh, 0-100 2.8seconds. Quickshifter standard, it sounds like a god-damn rally car. And it's my daily work mule.

Why do motorcycle engines make so much more power than car engines

Way more highly strung, motorbikes typically do way fewer miles than cars

Smaller pistons with less mass can be revved much higher.
Sorry for spamming a car thread. Someone said k series, and as Ricardo plc helped produce this bike you could almost say there's a little bit of Veyron in there

Favourite I4 is SR20DE in Nissan Primera (first car)
>Same engine as in 180SX and Silvia's
