Dragoncito
Estimados señores,
Let me first introduce myself.
I am dutch born, have worked over most of europe and 13 years ago moved to an old ´river cottage´ andalucian style in the mountains of the andalucian heartland.
We live a slow-life with priority at existential quality time.
Writer/horse guru (see homocaballus.eu )/ farmer by profession and we have two ´Mercedes´ diesel engined SsangYongs:
The Musso is the family car which I have set up for fuel economy.
The other is a cabrio Korando 2.9 TDi which is both farm work horse and fun project.
The Korando we baptised ´Dragoncito´ wich means Little Dragon. Very apt Since SsangYong translates as TwoDragons.
It is currently ´Stage 3´
I will put the mod details to the IP on that subforum.
Stage 1. was:
- K&N filter elemnet
- EGR ´blocked´
- Pump mods. phase one.
- snorkel
- pcv catch tank
Stage 2.:
- Air support at the rear
- stiffening front
- 50 mm wider track rear, 10 mm wider front
- air vent in the bonnet behind manifold cross over keeping the under bonnet temp lower
Stage 3.:
- mbc and boost from 0.5 bar to 0.8 bar
- pump timing 7 degrees less retarded
- two mufflers replaced by one 50 cm long 2,5" diameter straight through rvs Simons resonator
- pump mods phase two
Next stage is Butane injection laid out as an N2O system.
This is currently in the headache phase. I have the bits but the engine being idi it is a tricky thing to set up safely.
Thanks for the attention.
Sounds like a pretty sweet project!
The in car view of my latest mod on Dragoncito; the system:
Stíll fiddling to get at the correct jet size :oops: :roll:
The IDI head is proving to be a bit critical; the orange hot swirl thingamy in the pre chamber is eager to pre ingnite the (butane) gas.
Also I run max gas pressure in order to get it mixed properly when injected but this means that minute changes in jet size give huge difference in flow.
To establish a ´before´ the NOSHIT I have done half a dozen of electronically timed 1/4 mile sprints yesterday.
The best run was:
16,73 secs.
139,86 km/h.
0 - 100 km/h. 10,18 secs.
Whichever way I translate that into horsepower, it comes around 200 already!!
As a perspective; the 3.2 six cilinder 4 valve petrol engine model had a factory spec of 220 hp and 0 - 100 in 9,8 seconds.
Not bad for an IDI OM602 TD.
larsalan I guess I need to look at this stupid ass drip shit. What you have to like mess with those elements on the pump? What a fucking hassle. then use some wire to hold the throttle open or some shit?
I like it
The fighter jet switches always get passengers asking questions

Can you put in a pressure regulator?
How about two switches, going to two small jets: One switch for mild flow and two for full power.

I already have a regulator, but the thing is not that exact and also variating with atmospheric pressure.
I could simply put in a standard lpg reducer/vaporiser but that would spoil the fun effect of binairy power boost. The max. is only some 25 hp at móst and when injected gradually the ´seat of the pants´ will be absent.
The car is already quite fast enough and I only want the fun factor of a boost kick.
The thing is to finding the right pressure to set. As I drive between sea level and 4500 feet, I need to make a choice like set it for say max 3000 feet and not use it above that.
Now combine the above; only 20-25 hp at max and the need to keep a safety margin = you want the pressure to be set a optimally as possible so as not to let a fair chunk of that unused.

You could try reducing the tubing diameter that feeds the LPG to the engine-a smaller tube would restrict the flow

Can you fill the jet in with solder and re drill it smaller? That's how I've made cheapo carburetor jets in the past. Can you get 1/8" lines (~3mm?) Some kind of restriction has to be able to limit your flow

Butane injection? Never heard of that one. I've heard of NOS, Methanal, CNG, Water, Propane.
But this is a first for butane.
Why butane? just curious

The chemistry:
Add one molecule of butane C4H10 (99% burn) and one molecule of diesel C16H34 (82% burn) = C20H44, which is the same molecular weight as 2x C10H22 Decane (97.5% Burn).
Add excess oxigen and the mixture will burn like Decane.
You see that it burns 15.5% more efficiently than straight diesel.
Mix only 30% and you stíll get 5% extra efficiency.
Think about that....
You don´t just get the extra power from burning the extra butane but álso from burning the diesel more efficiently.
Interesting I would like to see how this works on a dyno
Imo the dyno is less usefull than quarter mile numbers but here you are....
Here the effect of LPG at 2.5 bar through a 1 mm. (0.04) jet in the cross over manifold of an OM662 td:
Source; Qute´s truck on ssangyongownersclubofaustralia.org
The hp result adds up perfectly with the theoretical flow rate and specific consumption of this engine.
This net result does not appear very impressive on the dyno chart but when overtaking or climbing a hill on the road is like shifting down a gear.

An instant boost in power is always great even if the chart isn't a straight vertical line

That's pretty impressive on a stock engine?

First to freshen it up, I will start from the inside and take it from there:
It is fed through a 2,5 Bar regulator from a 14 kilo Butane bottle strapped to the roll bar leg in the boot. This is a standard regulator on a common cooking/camping bottle which you can exchange anywhere. The bottle does not need to be installed, so you can leave it at home if you don´t want it in the boot.
The dashbord switch actuates the solenoid on the bottle and primes the system.
The WOT switch the injector solenoid.
The injector has a jet of 2.0 mm. and feeds a two-way nozzle in the crossover manifold. The jet is in the injector outlet in the fuel line and can be changed in 5 minutes.
I have tried several regulators and even an unrestrcted valve but it all gave a wonderfull but bewildering variety of problems.
The first set up had a turbo pressure switch as extra operater safety but that was a pita. Now one simply has to not use it in the first two gears and only floor the last cm. above 3 K rpm.
I am stíll not satisfied as the injector runs too hot, so I have ordered a higher in line resistance with integrated heat sink.
The NOShit is not intended to be anything else but a fun kick in the back and extra top end oompf to enjoy.

The 25 hp ´water bottle´
p.s. The red ´cap´ is de open/close turn knob of the unrestricted flow regulator.
