To get the maximum power from the fuel, it has to be burnt completely and efficiently. This way, more power is delivered to the wheels and less unburnt fuel and products of poor combustion come out of the exhaust.
Old cars use carburettors in gas powered vehicles and mechanical fuel injectors in diesel vehicles.
Spark ignition vehicles used mechanical electrical means to time the spark.
These items worked OK. But that's it, just OK, not brilliant.
Modern cars use electronics and computers to monitor and deliver fuel correctly to the cylinders.
The position of the crankshaft is measured accurately and the information passed to a computer.
The output of the computer will fire the spark at the best time depending on the load and throttle position.
The fuel is squirted by an injector, which is electronically controlled by the computer. This can deliver an accurate dose of fuel at just the right time.
A perfectly tuned old car, will become out of tune quickly due to wear of the mechanical timing devices.
A modern car with ECU (Engine control unit) has sensors that use light or magnetism to detect engine position, so do not wear. Other sensors monitor temperature, air mass and exhaust gas. Feeding this information back to the computer, can allow the software to make immediate adjustments.
This is something old cars just cannot do.
You can however fix an old car with a big hammer and a penknife.
A new car needs a PHD in electronics or a big wallet to fix and hope that you are not miles from either.

∙ 12y agoOlder cars tend to have less efficient engines and outdated emissions control systems, which can lead to higher levels of pollutants being released into the air. Over time, parts can wear out and become less effective at minimizing emissions, contributing to greater pollution output compared to newer, more environmentally friendly vehicles.
The control group in this scenario is the car filled with the normal gasoline. The control group serves as a point of reference to compare the effects of the new gasoline on the other car. It allows the scientist to identify any differences in performance that are attributable to the new gasoline rather than other factors.
A solution with a pH of 9 is 10 times more alkaline than a new solution with a pH of 7. This is because pH is a logarithmic scale, with each unit representing a tenfold change in acidity or alkalinity.
When magnesium reacts with hydrochloric acid, it forms magnesium chloride and hydrogen gas. This reaction is exothermic because it releases energy in the form of heat. The formation of new chemical bonds in the products releases more energy than is required to break the bonds in the reactants, resulting in the release of heat.
Aluminum can tabs can be recycled into new aluminum products, such as cans, cookware, or car parts. The tabs are typically made of the same material as the rest of the can and can be easily separated during the recycling process.
Exothermic reactions occur when more energy is released forming new bonds than is required to break bonds in the initial reactions. In these reactions, the overall energy of the system decreases, and heat is usually given off to the surroundings. This excess energy released contributes to the stability of the products formed.
you can but its not always wise because you could end up buying the new car for more than what it is actually worth.
Getting insurance for a classic car is very similar to getting insurance for a new car. The only difference is that it is more expensive to insure a classic car than a new car.
Absolutely not. Americans consume nearly 25% of the world's oil, yet still have not signed the Kyoto Protocol (which New Zealand developed) to counteract their consumption and carbon production.
It's because the new car engines are newer and aren't used like the old ones, so the new ones can work faster and more powerfully.
Yes, if you take out collision and comprehensive insurance. The more the car is worth the higher the insurance premium.
The new car is much higher. Since there is no history, no previous owner, and no miles on the car, it is going to cost much more to buy new, rather than used.
Well if your car can drive on water, it shouldn't take you more than a year to get there.
If the repairs cost more than the car is worth, buy a new one.
If you are trading in a vehicle in which money is still owed, the amount of money outstanding will be rolled over onto the new loan for the new car you are buying. If you owe $2500 on your current car, and are buying a car for $10,000, regardless if it is worth less than your current car, the $2500 note will be added onto the new loan unless you can pay it off beforehand.
junk the car a new starter and labor is worth more than the book value of the car
i think a new car is faster than a broken because.a new car are very fast some cars have different miles.
not much more than 4,000$
