Hi all Just thinking how to reduce fuel consumption. I've got manual n/a 2+2 and usually do 14-15l for 100k driving around Sydney but rarely stock in traffic. There are no ECU faults. I even though to change the car to something zippy (swift jazz yaris) but they drive way worse than ZX. Is there anything that could be done through datascan or other software? I also wanted to throw a spare tire to reduce some weight but the very next week caught a screw So this idea must go... What would you think about it?
Lots of things man, just do a search. Can be many things like leaking injectors, leaking fuel rails, stuffed exhaust pipes, worn out transmission (revving harder than you need to), dodgy tyres, rooted suspension...yes they all affect fuel economy.
If you are concerned with fuel consumption perhaps a 90's sports car isn't the car for you? Other wise just make sure everything is in top working order and control your right foot!!
bit on the high side, ideally you should be getting 11-12L/100. if there are no codes a good service is probably all the car needs.
Sounds about right. I get about 13l/100k in the NA convertible and 16l/100k in the TT. Half of my trip is normally free flowing Everytime you stop you use extra fuel to get going again, so it is the traffic that decides what consumption you get around town. You are also looking at an extra 1/4l or so to warm the engine up
Just as a note, I get 9.5-10.5L/100 on the freeway and around 15-18L/100 around town. Nothing silly, everything in A1 working order. I really don't see 15L/100 around town to be anything to be concerned about. They are an old 3.0L V6, even non-turbo, they won't run the same figures as a modern motor. If you want them to, then it's time to look at a different engine.
Well I tried different style of driving... and found not much difference. There nothing wrong with exhaust, fuel leak or other problems. Just wander if someone tried to reduce fuel consumption. it obviously wouldn't achieve vvt technology however 10L / 100k driving around city would be really great!
Noway!!!! They may be thirsty but the way they look! trying some average modern cars could find nothing like 300zx.
You can achieve 8-10 litres per 100KM on the highway, but not in the city, unless there are no other cars on the road with you, and all the traffic lights are green. Maybe at 3am, but not in general city traffic. See here http://www.pexcom.com.au/z32cms/e107_plugins/content/content.php?content.365
There is a few people I believe that have looked into or actuall had their car converted to LPG. The LPG tank size is the main issue. I hear some people have cut out the spare wheel well and put a flat sheet in it's place, then fitted a donut lpg tank underneath. Wouldn't be a huge capacity, but if you did enough klms to justify the conversion cost, might be worth while in the long run. I recently drove a vapor injected turbo Stagea with rb25, and I was very surprised and happy with the performance. Liquid injection would be even better. Food for thought perhaps. Ben
if your really really keen, you could adjust your tps so it reads a lower voltage, but this will lean out your engine and can cause serious damage if drove to hard and adjusted to far, and ofcourse if you wanted the normal nominal power again you'll have to get out and adjust it back to 4.45V again. just if you wanna try it
Have a look into hydrogen generators, I have had a hand in some trials of these of late and they seem to be quite promising. My mazda bravo which runs straight gas has seen economy improvements up to an additional 30%. Granted this is a high gain but also remember the lpg is very conducive to hydrogen being introduced into the system. Another vehicle, toyota land cruiser 75 series diesel improvements around 20%, isuzu truck, around 15%, kenworth K108, 620hp b-double, almost 25%, that right there is a saving of nearly 900 ltr of fuel from brisbane to melbourne and return. The benefit of hydrogen generators are they are vey cheap to run, do not increase harmful mmisions(infact can reduce). There are a number of systems on the market using anything from electrolite solutions, potassium hydroxide, vinegar. Thay can be as complex or simple as you like. Having played with both simple and pwm systems, the simple system with 2 or 3 cells will do the job very nicely. Expect a 10-15% improvement in fuel consumption. The system I have been playing with are not available, but expect to see them early in the new year. Do some googling and see what you come up with, there is alot of good and bad info out there, just be open minded.
ooo i like your thinking. i like wise have played with hydrogen. i made an easy 15% on my toyota celica(86 with efi) and that was with $30 of material and a reasonable bit of homework, it was my first design and it worked ok, then my second one got me about 20% but it was still crude. i use to use baking soda cause it dosnt affect the burn and its cheap and we had it( parents didn't have to know, or wife or husband for some of you) burning hydrogen is so much better in almost all worlds to for your engine, it cleans it and speeds up combustion speeds, burns more of the fuel in the chamber and an interesting thing is that it reduces the tendancy to knock.
