Am I nuts to plunk a Diesel into an Aveo?

I got a huffy with unlimited mileage that I'll trade you.

it's a 12 speed, I'll even throw in a new set of tires and tubes.lol

Thanks for the valuable info and advice, PrecisionBoost. I appreciate it and I'll start following some of that up. I think looking at the Corsa, especially from Asia, might be a really good way to go. I'm a bit concerned about the Smart Diesel as 800cc might be just a bit too small for the Aveo's bulk as you said and building a hybrid may just be beyond my mechanic's ability to fathom... he is a glorified shadetree guy anyway. I have a Honda Shadow but it's not easy getting the preggers ol' lady on the back for those 500 km trips to Kelowna.

As for the bicycle, I can really see putting the ol' lady on that!

Pir0, we have a lot of mountains in this area so I would still need some way to get up them. What would really work well would be an engine management system that shuts off 2 cylinders like some of the new cars, but of course, that system is only available in huge guzzlers.

The whole "lower the RPM" and "shut off cylinders" thing is a farce.

When it comes down to it you require a specific amount of torque to move your car forwards... end of story.

If you run at a lower RPM your engine will be outside of it's peak efficency and you will get worse gas mileage. ( I'm assuming it's peak efficency is up in the 4K to 5K RPM range )

If you run on just 2 cylinders they will have to work twice as hard to create the same torque ( thus getting similar economy)

Yes... you do save a little bit of fuel economy if the valves open up and the piston does not need to compress the intake air.... but many systems don't do that.

So.... just how do you get better fuel economy?

1) reduce the weight of the vehicle which reduces the amount of torque required to accelerate the vehicle
2) reduce tire friction by purchasing "low friction" tires like the ones on the Honda Prius
3) reduce air drag by reducing the vehicles coeficent of drag ( best way is to make the underside of the car completely flat )
4) increase the efficency of the engine ( get rid of restrictions in intake and exhaust, increase compression ratio )
5) install a more efficent engine ( diesels are far more efficent than a gasoline engine )
6) use a brake energy recovery system such as an electric motor ( when you hit the brakes the motor acts as a generator and charges batteries.... then as you start moving again the motor drives the vehicle forwards )
7) reduce speed.... driving at 120 km/h uses way way way more fuel than it does driving 90km/h ( drag on car related to speed which increases non-linearly as you go faster )

use a better oil... synthetic 5W30 will have less drag than conventional oils
9) clean injectors and combustion chamber on a regular basis
10) install an underdrive pulley to decrease parasitic load from alternator/power steering pump (which can be very significant at higher RPM levels such as you might find on a highway drive )
11) install a good grounding system.... better ground = better signals and better ignition = more power for the same amount of air/fuel = increased efficency

I'm sure there are more... but that's a start

I appreciate your tips and several of them can certainly help gas mileage, but I think I'm starting to get despondent. For the first time, I can now say that I have in the tank of the Aveo regular unleaded fuel which cost $1.33.9 per litre. For our USA friends, that's $5.07 a U.S. Gallon. This means that this month I may top $500 in fuel costs alone. Now this is getting to the point where I have to start choosing between paying for my car payment, insurance, utilities and eating vs. driving. I honestly don't know what to do and the expectation is that the cost of fuel is going to continue going up. Let's not even mention heating costs for next winter.

I really don't know how much more of this it is possible to absorb.

Just to substantiate my viewpoint, here is today's CNN.com poll

The top economic worry for you and your family is:
Paying for gas 44% 66422
Job 20% 30436
Health care 17% 25354
Paying rent or mortgage 18% 27194
Total Votes: 149406

I'm not alone in getting seriously concerned about what's coming next for a family's battered finances.

Our petrol prices are said to be rising to 1.50 GBP per litre in autumn. I'll not be able to afford driving soon lol...

Anton

i am from India. And here in India, we can easily get a used Toyota 1N Turbo Engine from a junk yard. These used engines are improted from Japan and have already clocked around 60-70 K Kms. But these engines are quite good as I have seen these engines doing 300000 kms if proper care is taken. Here they costs around Rs. 32000 i.e. about $800.

The replacement costs is another $200. I don't know about ur country norms.

The engine comes with its own Gearbox (Automatic), Power Steering Pump, Alternator and AC Compressor. All you need to find are a pair of suitable axle to deliver the power from the gearbox to your tyres and 3 engine mountings.

I have done the same for Cielo. It delivers 67 BHP Power which is adequate for Aveo.

Does anyone even make an underdrive kit for Daewoos?

You've a lot to learn young padawan

Sorry to hijack this thread, but I thought it was apt news. You guys think our gas prices are high? Bosnia just set the new world record at $10.86USD/Gallon.

That means over $100 to fill up our car. And average monthly income over there is like $400/month

Yes, they are available but only for the 2.0L engine...... if you have the 1.6L they you might be out of luck.

over here is about USD$6 / Galon (premium that is), similar AVERAGE monthly income... maybe less... minimum salary is $122 i think.
