badass lawnmowers and Sith light sabers
So, even mediocrity needs justification. I drive a 2000 Mitsubishi Eclipse. It has a 2.4-liter 4-cylinder. It sounds like an angry lawn mower at 3000 rpms. I think it can beat a Ferrari, and I have an excuse for everytime it can't.
Did you ever wonder how a car's engine keeps running when it changes altitude? Well, aside from a 10,000 foot difference, it theoretically should keep running. Okay, so, have you ever wondered how a car keeps it's mixture in line with it's airflow to maintain a specific level of emission? Eh? Eh?
Okay so no, you don't wonder. If you don't care then don't read this... just move on to one of my other crappy entries and be done with it! This one's for the people who want to pretend to be technical. There is a mechanism on modern cars called a "Mass Air Flow Sensor." What's really interesting is that it has its own computing system that mates with the main computer in a car, and when the car is traveling a 110 miles per hour up a mountain (I'm late for work) it is compressing a huge amount of relative air that is constantly changing its density into the air filter. The MAF sensor tells the computer how much fuel to inject into the fuel/air mixture to keep the engine running smoothly, reduce emissions, and optimize gas mileage. So, with less air pressure at the top of the mountain, less fuel is injected to "lean" the mixture and therefore keep a healthy fuel/air ratio for combustion. Eh?
I know this because my Mass Air Flow Sensor broke and I had to replace it with a part from Ebay. It was so bad that I could literally tap it and my engine would shut off. So there. Also, check out "How Cars Work" on howstuffworks.com. I've learned how to build a car, treat an alcoholic, make a computer virus, pick a standard dead-bolt lock, and put together a light saber Sith and Jedi-style. When you're on a quest to learn, well, everything, I highly recommend this website along with the WikiMedia Project.
