Featured 105: - Uhuru-

[-uhuru-]

Hi all,

This rig started out as a bone stock ’99 HZJ105. It had the 1HZ Diesel mated to a R151F tranny. This GX trim model has a full time transfer case and hydraulic brake booster with a 4 channel ABS system, just like the *ZJ100’s. Besides those “luxuries” this vehicle is pretty simple and has only basic comforts such as an A/C with normal buttons (non LCD display!!!), airbags, power windows, bucket cloth seats, and third row seating (removed).

Propane Injection System

Nice looking rig...front bumper looks like Slee's prototype...more wheeling pictures please...

 

[macneill]

Yes, we need much more eye candy.

Thanks, I hardly have any pics of the rig. I took those yesterday with my phone. Lost my camera!

The rig has hardly seen any trails. It's mostly a work truck. It gets me to and from surf spots too, so it sees a lot of sand. Thats why I chose the Dune Grapplers. They do well on pavement.

The wheels and suspension are being pulled out right now and 6" Slee suspension kit will be placed. Axles are also being converted from 5 to 6 lug. 4.88 gears are going in and a rear air locker for now.

what GPS/Raido is that?

You guys with the 5 speeds and solid axles really piss me off! Kidding. Nice rig. I am very jealous!!!

I can't remember but it is only a radio/DVD player. The GPS is a Garmin Nuvi 200W, not shown in the pics. It has a suction cup mount on top of the dash pad.

I will check the model number for the JVC head unit.

x2. Many more of the HZJ-105s build threads may cause me to go ex-pat.

Thanks for sharing and glad to see another cruiser used for work.

nice!

could you elaborate a bit on this propane injection system and how well it works? It's injecting the propane as a vapor directly in the intake? So how is the extra fuel taken into account in making sure the air/fuel ratio is still OK?

That looks like my 80's but with a 100's body!

DieselGas Technologies - LPG injection system for diesel engines...

Yes solid axle and a 5 speed manual is great except they come standard with the R151F witch is not as strong as the R150F.

Looks tough with those wheels and tyres on it.

Is the front bumper custom?

 

[sleeoffroad]

Damn, that is a good Slee copy

not many details in there.
They do repeat a lot that the propane system is independent, which is the point of my question about the A/F ratio. I can see that the propane system injection could be adjusted by the boost, but how does the diesel fuel injection system know that there is propane going in there too now?

 

[98lux]

not to sure on that, but i think it is like putting a turbo on a 1hz motor, The gas helps the burn rate of the fuel going in so it burns more of the fuel ( normal burn rate is about 70%, with gas it burns about 95-98% of the fuel) so therefore better performance on the same amout of fuel but more power = less right boot = better econmey.

It's a SLEEP (Slee de Panama)!

It doesn't, you are adding 20% of propane to a 100% diesel fuel load.

There are essentially two types of performance/towing/economy propane injection systems comercially available for turbo diesel engines: fixed rate and variable rate.

The fixed rate systems flow a steady rate of propane once a preset boost level is reached. They are usually activated by a Hobbs pressure switch. When the system is activated, say for example @ 5 PSI, the system kicks in at at full rate (whatever amount of propane it is set to). This type of system typically uses a regular propane tank that draws propane in liquid form and has a vaporizer unit that uses hot water/coolant which turns the liquid propane into gas for injection. Fixed rate systems are known for suddenly "kickin in" and giving a really jerky type of ride. This is the type of system that Bully Dog offers as well as other aftermarket manufacturers for US domestic trucks.

Variable rate systems flow propane in proportion to boost level. They flow the full rate only at maximum boost and get there progresively. These types of systems give a much smoother powercurve without a sudden spike. Instead of using a pressure switch, a diaphragm is employed. Maximum rate of propane and maximum boost level are adjustable. This system uses a vapor draw type tank which draws from the top of the tank in vapor form. There is no need for vaporizers or mixers. Propane is injected pre-turbo and after the air filter in the intake pipe. There is simply a cut hose going into the air intake pipe. No nozzles or jets to deal with.
