Will Petrol Engines become more and more efficient over time?

Question

Apparently they are only 30% efficient which isnt very impressive. That is to say 70% of the energy in the fuel is lost through mechanical loss.

Answer 1

Most things become more and more efficient over time

Answer 2

They always have been improving, particularly with the more recent emphasis on MPG as a selling point.

My 1997 Honda Civic 1.5, you would think would burn more fuel than my 1989 Nissan Micra 1.2, but you'd be wrong. The newer car gets about the same MPG, which isn't bad for a bigger engine. And looking at figures for new cars, they get even more MPG.

Car manufacturers aren't silly. They know fuel prices have gone up, and they know they can sell cars if they tell people they drink less fuel. Another example while I'm here - my dad just bought a new BMX 325 (2.5 litre). It has the same power output as his slightly older Z3 2.9 litre, because BMW have made a much more efficient engine.

Answer 3

Petrol Engines are more efficient now than they have ever been. I'd say you have your 70% and 30% the wrong way round to be honest. Engine technology will continue to improve until a more efficient means of propulsion is invented.

Answer 4

they have become more efficient since their design and will become more so, i doubt they will ever become truly efficient due to the size constraints needed for a vehicle engine.

PS: turning tapwater into a power source can be done but requires a eual amount of power put in. First you must seperate the Hydrogen and oxygen then you can burn the hydrogen to power your vehicle. the seperation process uses exactly as much energy as the recombination provides (and then you have efficiency losses to consider)

Answer 5

RUN YOUR CAR ON TAP WATER!
IT ALSO WORKS ON YOUR
TRUCK / RV / MOTORCYCLE / AIRPLANE (ETC)

This is not a joke! - This can be carried out using readily available components and some mechanical know-how!

Suitable for all engine types, including turbocharged and supercharged - No petrol or diesel needed at all - EVER!

Amazingly, your vehicle will return more miles per gallon (of tap water!) and engine power will be INCREASED by around 33%. Once again, this is no joke.

This conversion was demonstrated on BBC's 'Tomorrow's World' program in 1986 at the Jensen test track in the UK. The engine will run off the 66% hydrogen found in water.

You can expect to travel a distance of between 50 and a theoretical 300 miles per gallon of water, depending on the set up and adjustments made. Cost of parts needed is under $100 though several hours labour time are required to fit and set up the system.

18 page guide to doing this (complete with diagrams) as soon as payment is received. My guide is concise and explains the scientific and engineering principles behind using water as a fuel, and how to make the conversion on your car, bike or truck engine. Even if you feel unable to perform the conversion you will enjoy reading my guide and will certainly feel knowledgeable afterwards!

Every succesful conversion is a step in a new direction. The future is unwritten!

Given a choice, which way would you choose?



Frequently Asked Questions



Q: Does it really work ?

A: Yes; this is well-established technology dating back to stainless steel. But be sure to follow these instructions using the proper mechanical and electrical assembly techniques, as this plan incorporates the best qualities of several techniques.



Q: How does it qualify as "free energy"?

A: If you're paying someone for the water you use, then it is not strictly free. But the alternative is to keep buying into expen$ive ga$oline and its resultant hydrocarbon pollution.



Q: Is it safe?

A: Technically, it is safer than running on fossil fuel because you are no longer choking on your own emissions (health-wise). In general, it is practically as safe as your current gasoline arrangement. You will be installing a few simple safety devices, using current automotive standards.



Q: What kind of performance can I expect?

A: Properly adjusted, your modified vapor-only fuel system will run cooler, and at a modestly higher power level. The mileage performance expected from this design ranges from 50-300 mpg (of water), depending on your adjusting skills.



Q: Can I do the modification myself?

A: Why not? If you don't have any mechanical skills, and you know someone with basic mechanical and/or electrical skills, you can even delegate some of the construction. If you are using a fuel-injected engine, you may have to get a mechanic's opinion. [There will have to be an adapter inserted into the fuel-injection system, just as you would have to do if you were going to run on propane, hydrogen, or natural gas. Ed.)



Q: What is the environmental impact that my vehicle will have?

A: It will be producing H20 steam (water vapor) and unburnt O2 (Oxygen). Hence, it will be cleaning the environment, rather than dumping nauseous toxins into it. Plus you will be helping to save our dwindling supply of atmospheric oxygen. Any excess vapor in the reaction becomes either steam or oxygen. You can also expect to be receiving more than casual interest from those around you.




Q: Isn’t this really a steam engine?

A: No. Really. Exceedingly high temperature and pressure are not used. This is strictly an internal-combustion engine (burning orthohydrogen) with residual steam in the exhaust as a by-product.

Answer 6

Between you and me the powers to be that's the oil and auto are not going to let it happen .If you look back in the history of the auto there was a few cars made that put ford chevy chrsy dodge to the real test and made them sick there was no compotition they can put car on the road right know that get over 100 mpg easy buut you did not hear that from me just look it up for your self

Answer 7

Yeah, but they're already nearing maximum efficiency what with Volkswagen's TSi engines and whatnot. Same with diesels.

Answer 8

Of coarse, but like now they are more efficient than 20 years ago so every one buys enormous SUV's so where is the point,

Answer 9

They will have to be, as gas prices are going up day by day.

Answer 10

I'm sure they will.
