LPG Jeepney for cleaner public transportation?

[ghosthunter]

Is Auto-LPG a possible answer for cleaner & cheaper public transportation?

Well, maybe not cheaper for the riding public but the cheaper cost of fuel might be a good incentive for PUV/PUB transport companies to take another look at LPG as a viable fuel.

Although not really viable as a direct replacement for diesel in large vehicles (like buses), LPG can be more applicable for smaller vehicles to replace current vehicles like the jeepneys and FX-shuttles.

The plan may not be as "radical" as the electric jeepney but this is more viable as the vehicles themselves will not be replaced by INFERIOR substitutes with many unmentioned but undeniable shortcomings.

Simply put, replace the fuel with LPG.

Of course you can not use LPG in diesel engines so the best option is to start from the source. Make a jeepney (or similar vehicle) that will use an engine that will use LPG as fuel. Make the engine simple so that even ordinary mechanics can service them. Use common engines as a base so parts will not be difficult.

[SIZE="4"]Toyota LPG Cars[/SIZE]
By: Victorino Sianghio Jr.

The best Toyota LPG Cars are cars that are made by Toyota and run on LPG, which is an acronym for liquefied petroleum gas. This type of gas is said to be more environmentally friendly because it is cleaner burning.

1. Toyota Camry Altise V6 Automatic/Ateva V6 Automatic. This Toyota LPG car on its Camry line of cars is outfitted with a Quad Cam V6 engine, which is compatible with LPG technology for cleaner burning fun. This special LPG engine from Toyota itself is a 3.0 Liter one and also includes special fitted valves along with valve seats. It is so easy to convert from normal fuel to LPG that all it takes is automatically reaching a certain level on pre-set RPM and temperature values.

2. Toyota Avalon Advantage/Conquest. The Toyota Avalon Advantage/Conquest range of LPG cars from the company features the LPG-conversion kits. These kits were devised by Toyota and Apollo Gas and ensure that your new, environmentally friendly Toyota car has maximum fuel efficiency, reliability, performance, and driveability. This fuel system was designed by Toyota itself to its own engineering standards. Another bonus is that Toyota's great warrant of three years/100,000 kilometers also applies to these newer LPG models of their cars.

3. Toyota Town Comfort LPG. The Toyota Town Comfort LPG car is a car that is used by Toyota exclusively in Hong Kong. So far, there have been three models: the YXS10, the LXS10, and the latest one, the YXS11. This LPG car by Toyota is also used as a taxi sometimes, and its engine is an L4 DOHC 16-Valve VVT-i Engine.

I posted the following in another thread but I think it deserves to be re-posted here...

...

The idea is there for anyone (including yourself) to grab and turn it into reality.

Previous (government sponsored) attempts of doing LPG-Jeepneys have failed because those were converting existing jeepneys to run on LPG. Previous efforts also suffered from the usual PGMA regime financing corruption which cut the number of jeepneys that were supposed to be converted.

The difference here is it will use an engine already meant to run on LPG from the start.

All the Auto-LPG refueling stations are available in the metro.

It wouldn't be far off to use an affordable Suzuki Multicab shuttle with an engine converted to LPG as a testbed for a more wider adaptation.

The general success of LPG-fueled taxi cabs is an indicator that LPG is a possible way for public transport to save money on fuel as well as go a bit greener.

[ghosthunter]

I mentioned of possibly using Suzuki Multicab units as a possible vehicle becuse these are cheap & plentiful. P150,000 is already enough to get you a unit. Maybe a budget of P50K about be enough to convert it to a PUV type which can hold ten to twelve people in the back and make it run on LPG as well.

So for only P200,000 for each vehicle, you can have a PUV that is cleaner & cheaper than the standard PUJ. It would be faster than a certain electric golf cart used by Makati and definitely will not have a 60km daily range limit and will not need an eight hour recharge every day. All that is needed is to locate the nearest convenient Auto-LPG station, which is not a big problem in Metro Manila.

If this proves cheaper to run than the standard PUJ, it could start a gradual phase out of the standard PUJs off the road as drivers/operators shift to this LPG fueled option.

The Hong Kong government plans on replacing all diesel taxis with LPG taxis by the end of 2005. By the end of 2003, about 18,094 LPG taxis were operating on the roads, representing over 99% of the whole fleet. The replacement of diesel taxis with LPG taxis helps improve the air quality in Hong Kong.

So if we replace diesel PUJs with LPG PUVs, the air in Metro Manila can actually improve (if sufficient numbers of replacements are done).

One way to achieve such a goal is a legislation of government to accelerate owners/operators of PUJs to move towards LPG. Tax exemption or even tax credits for early adopters may also help.

Another way is to make LPG PUVs exempted from the traffic coding scheme.

Liquefied petroleum gas (LPG) vehicles

Liquefied petroleum gas vehicles e.g. LPG public light buses and LPG taxis produce much less pollution than diesel vehicles. Table 2 shows the results of a comparison of diesel public light buses with LPG light buses. You can see that LPG produces much lower emissions and particulates. This is a major improvement compared to diesel.


Table 2: Test results comparing diesel with LPG public light buses

Too bad they don't bring in the Toyota Crown/Comfort here. It's a great proposition for a taxi cab because it has legit space in the backseat for 3 adults plus a big enough trunk space. Yun nga lang, the boxy shape and the dull-black interior are a throwback to when they made cars in the early 80's.

Even the instrumentation cluster is all analog and squarish. But hey, it gives a comfy ride if you're a passenger.

Too expensive for the taxi cabs we have locally. You have to remember HK cabs are generally bigger cars. Compare that to the typical Vios & Sentra used as taxi cabs here.

sayang wala na ung gas-fed L300..or the advie(doesn't quite have the carrying capacity of a jeep though)

a lot of the chinese brands here have their multicab equivalents; dunno about build quality/parts availability though.

True. The L300 gas fed version would have been my first choice if it was available. Second would be Tamaraw FX.

bringing this thread back from the grave.

I searched "diesel to LPG conversion" and apparently, it can be done. At a staggering cost of US$7,000 to 12,000!!!

Definitely not for our "kawawang" jeepney driver.

So I checked "Diesel to LPG".

What I found out is Diesel-LPG Dual Fuel Kit. Diesel and LPG are used simultaneously.

"The addition of LPG to a diesel engine allows it to use a smaller throttle opening; therefore, the amount of diesel that is used is decreased. Tests have proven that you will save roughly 30% on fuel bills if you make the conversion. If your appliance/vehicle is an older model and has a less efficient engine then the savings will increase." Diesel LPG Conversion Kits - LPG Conversion Kits

But another site says: Can Diesel engines be converted to run on LPG?


What do you think? Is Diesel-LPG a possible solution to the ever increasing pollution from our jeepneys?

Converting jeepneys to use Auto-LPG requires to change the whole engine.

The cost is cheaper than adopting an existing diesel engine to run on LPG.

Unfortunately, too many politico had their filthy hands on the money even before it was allocated to the jeepney drivers/operators. The result, less than 1/3 of the money allocated was actually available to convert jeepneys.

This is not Diesel to LPG conversion but rather Diesel with LPG System. The website calls it "fumigation" probably because diesel fuel is fumigated with LPG before delivery to combustion chamber.

There will cost - monetary and probably performance so it is interesting if it worth considering.


Re: money. Does the govt already have program and budget for the jeepney fleet to convert to other fuels???

LPG fumigation of diesel engines is like using nitrous in gasoline cars. It adds power. But you cannot use LPG alone in a diesel engine. This has been using by truckers when they need extra power in going up hills.

Yup. It's old news.
