Auto-LPG Conversion Thread

[Bry]

They gave me two reasons:

-Ididiscriminate daw pag nakita na Macro yung kit

-Minsan daw nagkakaproblema, nagtutubig daw or naglalangis yung tanke

[chuaed]

grabe ah, pag nakita makro kit descriminate ng Naiadss? hindi ko alam iyan ah...

with regards sa nag lalangis, at nagtutubig wala pa ako nararanasan regarding diyan, nag ka-karga din ako sa Naiadss, petron, at manila gas... pero madalas sa manila gas sa c5 pasig...

kadalasan karga ako kung saan ako naubosan...

[ghosthunter]

I think its a gimmick of Macro to keep customers buying their fuel especially with NAIADSS as their major competition. I have been refilling at the NAIADSS stations as well as other LPG stations. I don't see any discrimination being done to MACRO equipped taxis. As for water contamination, I have yet to drain my tank of any water but my evaporator is barely wet with water when I had it drained in July of this year (11 months after installation).

Anyway, water in the tank doesn't do anything to the system except lower it's storage capacity. Draining the tank of water can be done at any of the LPG stations equipped to install these kits.

ok un sobrang matipid. kaya lng mas bibigat sya.

[webmiester]

Anyway, is it true that it is not advisable for those who are using the Macro kit to fill up in other LPG stations? They advised me to tell my drivers na NEVER daw magkakarga sa NAIADSS, and as much as possible dapat sa Macro lang. Is this true or gimmick lang nila?

I'm having the kits installed first thing tomorrow morning, is there anything else I should know before I push through with the install?

I don't know about this, but it doesnt make any sense. Why should NAIDASS gasoline stations discriminate when they're making money out of selling LPG to you? Maybe the longer service time could be because NAIDASS uses the bayonet type of LPG valve and they will still need to install an adapter before they can refill your tank. Some stations dont have so many adapters so you might have to wait till an adapter becomes available.

Have you checked your spark plugs and air filters? the technicians might require you to change them. Perhaps it would be wise to check them first, then if they need replacement, purchase the parts outside. They might offer to change the parts with their own supplies which might cost more.

my car was recently serviced at chevy dealership casa(40,000 kms PMS) which they replaced my spark plugs air filter, change oils, etc...

with regards to spark plugs and air filter, okay pa siya kung tutuosin pero kailangan daw kasi kaya no choice...

[boydapa]

hello!

patulong naman gusto ko sana matuto mag adjust ng lpg tartarini kit ko on my carb ride. paano ba gawin ito. tinitignan ko yun gumawa dati at parang may inikot syang screw at inikot na malaking pihitan na may spring ano ba yun mga yun?

or is better na pagawa ko nlng sa kanila at may equipment sila? saan
ba pwede magpatune na may equipment dito sa qc malapit me sa commonwealth. thanks!

Ive encountered 2 units (1 Nissan Sentra series IV with a ventrino system with emulator, and a taxi using a korean ventrino kit) both having this bad smell sa exhaust, para bang hindi nasusunog yung lpg. Yung taxi even had white smoke coming out.

Anong cause nito?

Im beginning to have suspicions on these guys. My car's air filter and spark plugs havnt been changed for a long time and they didnt need replacement.

Could be the air filter needing to be cleaned or replaced... actually replaced would be better since blowing the dirt off with compressed air through the paper filter isn't going to help much.

Yung taxi even had white smoke coming out.

it's a taxi... enough said.

Wow.

LPG price from P24.13 to P25.73 = +P1.50
Extra price from P41.57 to P41.07 = -P.50

Oo nga. Ive been noticing a fast increase in the priceof LPG Im wondering kung tama yung mkga sinabi ng mga taxi drivers that the LPG will become expensive too, kaya it won't be worth it...

I think this could be a case of supply and demand. Apparently, demand is coming up because LPG is becoming more popular but the suppliers still remain the same. It takes only a day or two to convert a car into lpg, and we have lots of people doing it... While it takes DTI registration, BIR, Mayor's permit, etc.,etc. to build a new lpg plant, and only a few guys are doing it. So I suppose the demand is picking up faster than supply at the moment. Unless the government can streamline business here in the Philippines, the disparity will continue.

LPG so far is still cheaper than Diesel. Kaya Im wondering if its better to start having Gasoline engines na converted into LPG for jeepneys rather than keep them on diesel or diesel/lpg mix. It'l be better for the environment, and it might cost the same as converting a diesel engine into a mixed diesel/lpg system.

Im wondering what the effects of the unburnt lpg is on the environment. Im sure hindi ito mapipickup ng emissions testing, but it still makes me wonder what it's effects are.

Also, can the car's engine be on lpg when testing emissions for registration. Di ba yung registration natin still remains as "Gasoline Engine"? Pero I heard a lot of converted taxis can no longer use their gasoline systems, partly to reduce cost.

I've had bad experiences with GM philippines. Bought a used car before and didnt have a problem for almost 2 years til I brought the car to them for maintenance.

After that 1 maintenance, I went back to them for 'un-explained' breakdowns every 2-3 months after that 1 maintenance trip. This happened til I had enough and sold the Car. My Conspiracy theory is they booby trap so that you keep coming back.

Anong cause nito?

yung bad smell... air cleaner needs replacement or bad a/f mix(rich).

white smoke(valve seals,piston ring), bad a/f mix... engine needs attention.

with regard sa taxi na hindi na ginagamit ang gasoline... ganun na din sa taxi namin. 1 reason would be kasi hindi kaya ng solenoid i-hold back yung gasoline from getting into the carb. kaya ayun, naghahalo minsan gas ang LPG. result.. not good. hindi maganda ang hatak and malakas siya sa LPG. this is my experience with the carb kit tsaka yung carb kit na may circuit para sa efi(which we use for the series 3 sentra). sa taxi kasi important na matipid sa LPG yung taxi mo or the driver leaves you. medyo maselan na kasi taxi drivers ngayon regarding LPG consumption unlike before nung una lumabas ang LPG kits.

work needs to be done with the switching(gas to LPG and vice versa) system.

im not too sure about the "reduce cost" reason.

one other thing is, wala nang driver samin na gumagamit ng gas anyways so i didnt bother contemplating for an improvised system for a better switching system.

[dencio1976]

add ko na din. sa taxi, if LPG converted na, LTFRB gives out +2 years extention of the franchise of the car.

mapulitika ang taxi(can't speak for other PUV's). i doubt na meron nagpapaemission test na malaking company. kahit mga hindi malaking company skips the emission testing. basta may connection and d-bayad.

BTW, would anyone be interested in an LPG alarm?

It's 220v, detects LPG and gives a strong alarm when it detects LPG. I will be installing one in my car, under the front passenger seat, kaso since its 220v, i still need to install an inverter (kaya I opened an inverter thread, hehe).

Anyway, I think it'l be even more useful inside the garage, since lpg which leaks out of the lpg tank are released to the underside of the car via copper tubings. Kaya if your car has a leak, it will leak out into your garage while the car is parked...and in case you smoke in your garage... well, you'll get the picture.

Anyway, For many taxi drivers, they like removing the clear plastic cover of the lpg tank seal while refuelling lpg, plus they open their trunks while refueling, greatly increasing the risk of lpg accumulating inside the cabin...kaya some passengers complain of smell which they presume is lpg.

Anyway I found the US-made alarm, and I can get you guys some more for about P899 each if you guys are interested

LPG, aside from being flammable, is also poisonous.

sa taxi drivers, simple lang, kasi gusto nilang makitang mabuti yung needle. also, pinipitik nila yun para tumaas daw kasi dinadaya nila partner nila in the process. i think it's a waste of time trying to figure out taxi drivers. bihira ka makakausap ng matinong taxi driver. ive been around taxi drivers since i can remember.

never really had leak issues for more than a year now with 60taxis. hope to never encounter one.

ah nakalimutan ko. we had 1 issue pero it was no leak. nakalimutan nung driver sa "on" yung susi. tartarini yung kit. left for about 1hr or so. hindi sya nagstart agad kasi lunod na sya. nangamoy yung engine bay. badtrip na badtrip ako dun sa driver.

Web,

"poisonous"? That's the first time I've heard the word used about any publicly available automobile fuel! What do you mean?


Carbon Monoxide fumes from petrol and diesel are poisonous, but raw Propane does not produce CO and is so safe that forklifts are converted to Propane so they can be used indoors, just like your gas stoves......

please enlighten us?

[ssalonga]

Why Use Propane?

Cars are converted to propane or Liquefied Petroleum Gas (LPG) generally because their operating costs are much lower than for gasoline. Nowadays, automobile conversions are much more popular in Europe than in North America. Conversions were quite popular in Canada in the 1980s because of government incentive programs. In North America, the best candidates are vehicles in fleets driven long distances because the lower operating cost makes a faster payback in recovering the capital cost of conversion. The main concern in this type of conversion is cost and performance is a minor issue.

Although propane has a higher energy content (J/kg or BTU/lb) than gasoline, it has a lower density (kg/litre or lb/gallon). Because of its lower density, a car running on propane will have a higher fuel consumption than one running on gasoline but its higher energy content will compensate somewhat for the higher fuel consumption. When the fuel price is factored into consumption, the driving cost ($/km or $/mile), propane is significantly cheaper to use.

An additional benefit of propane is that, as a cleaner burning fuel, fleet vehicles last much longer between overhauls. Propane does not produce carbon deposits in the combustion chamber no matter how long it is used. Without the carbon deposits, engines do not require higher octane fuels to compensate for the gradually increasing compression ratio or the hot spots that cause preignition. There is no carbon to blow by the rings to contaminate the oil, which allows the oil to remain clean. Engine oil at 10,000 km will look as clean as newly changed oil. The main problem with the oil is that extended distances between oil changes cause the lighter parts of the oil to boil off and the oil gradually becomes more viscous.

A good place to start research for a propane conversion is Jay Storer's book: Economy or Performance Propane Fuel Conversions for Automotive Engines. It was published by S-A Design (ISBN 0-931472-12-1) and appears to be out print now. A few book sellers still seem have it stock however. Another useful book to read is Larry W. Carley's Propane Conversion of Cars, Trucks & RVs. It is published by TAB Books (ISBN 0-8306-3103-8) but this book also seems to be out of print. You may have luck finding these books in your local library.

An excellent source of information is Franz Hofmann's publication: Diagnostic Guide to Alternative Fuels. Besides great general information about LPG-fuelled engines, it also has a lot of LPG engine-building and repair advice. His very reasonably priced book contains the most current and comprehensive information about North American alternative fuel systems available anywhere. For more information, please have a look at a preview of Volume 1.
Cars converted to propane generally suffered a performance loss in the bad old carbureted days. The problem was that propane was metered (or fumigated) into the engine in a gaseous form. The fuel gas displaced air that the engine was drawing which caused a slight loss in volumetric efficiency. Gasoline is metered into the engine as an atomized liquid. The density of a liquid is much greater that that of a gas and so the volumetric efficiency loss compared to pure air is negligible. The other contributor to lower volumetric efficiency is in the restrictive mixer.
