The regulations just steered everyone in the right directions speeding up the change. And folks say the government isn't good for anything.

It isnt.


You folks are out of your minds with the carb talk. Drivability alone would be pushing technology. Nobody is going to want to talk on their iPhone and have to pull a choke cable to get their new car to start. (Over the top example) Are they pushing to meet all these standards yes, they would still be making new advancements without them, maybe just a different direction or slower pace.

1990 Camry vs 2018 Camry, I bet the price points are pretty big too.

You wouldn't have much to see on the iPhone if the government's DARPA-NET hadn't come first.

No one doubts that technology would still be making cars better. But, the clean air push undoubtedly made these changes faster, and in the long run cheaper for the private sector to make thanks to the government funded R&D. America would suck without our private industry, would also suck without our strong democratic government. It is a pretty good partnership overall. Worst system of government and economy, except for all the others.

Yeah, carburetors are gutless

it's possible to get a carb'd vehicle to pass today's emissions regulations ... you just have to hand tune every one coming off the line for the exact environment that it'll be driven. EFI was just easier to do it, and offered more consistent performance for the customer over longer periods of time.

Exactly. Carbs give you power, can give you tons of power, they just can't be made to give you consistent maintenance-free power. Fuel injections was inevitable, but regulations speed up the process and pointed it in a good directions.

I have 2 vehicles with carbs. I haven't had to touch the carburetors on them in decades. I've never heard of anyone saying "I need to fix that carburetor again".

Carbs might not be "fine tunable" like FI, don't work on steep inclines and can't adjust on the go to the environment. But they're very, very dependable. Got a dead battery? My carb & mechanical fuel pump still works.

Computer controlled FI is for two reasons:
1. More difficult for the average shade tree mechanic to work on.
2. Government regulations.

Seriously? "gotta get another carb rebuild kit"

A dead battery is a problem for any vehicle when starting it, so it doesn't really matter that way.

And otherwise, the fuel injection is much much more reliable day in and day out for starting a vehicle.

Easier for someone with a little knowledge to properly investigate instead of throwing parts at it. But then again most people who have issues with using new technology to work with newer cars are likely some sort of technological troglodyte who "can't work the computer"

Yup, emissions regs from the government pushed the need for better fuel control, the solution was FI. And without it we would have smog like China. I like clean air and being able to breath.

This country would be much more of a "**** hole" without such standards than it is.
