So, I came home with one thought<br \/>\non my mind:<\/p>\n<p>\u201cWhat is Fuel Injection?\u201d<\/p>\n<p>Like any smart woman, I started to do research on just what fuel injectors are and if<br \/>\nthe asking price given by the mechanic I visited was anywhere near fair.<\/p>\n<p>It turned out that fuel injectors aren&#8217;t anywhere near magic; but they are something<br \/>\nthat seems to be fairly complicated because of the fact that there&#8217;s a component<br \/>\ncalled the ECU that controls the amount of fuel that gets injected.<\/p>\n<p><a href=\"https:\/\/www.solopcms.com\/blog\/wp-content\/uploads\/2014\/04\/005fuelinjection.png\"><img decoding=\"async\" class=\"alignnone size-full wp-image-41\" src=\"https:\/\/www.solopcms.com\/blog\/wp-content\/uploads\/2014\/04\/005fuelinjection.png\" alt=\"Fuel Injection system detail\" width=\"377\" height=\"414\" srcset=\"https:\/\/www.solopcms.com\/blog\/wp-content\/uploads\/2014\/04\/005fuelinjection.png 377w, https:\/\/www.solopcms.com\/blog\/wp-content\/uploads\/2014\/04\/005fuelinjection-273x300.png 273w\" sizes=\"(max-width: 377px) 100vw, 377px\" \/><\/a><\/p>\n<p>The ECU, or the engine control unit, receives information from oxygen sensors.

They&#8217;re really just a fancier and more efficient way of doing what<br \/>\ncarburetors did before the 1990s when electronic fuel injection become feasible..<\/p>\n<p>There&#8217;s two types of fuel injection systems: single point and multi-port fuel injection.<\/p>\n<p>The former type is used in older cars and acts at a single point just like a carburetor<br \/>\ndid, because automobile makers were lazier than my ex-husband.<\/p>\n<p><a href=\"https:\/\/www.solopcms.com\/blog\/wp-content\/uploads\/2014\/04\/007fuelinjection.png\"><img decoding=\"async\" class=\"alignnone size-full wp-image-43\" src=\"https:\/\/www.solopcms.com\/blog\/wp-content\/uploads\/2014\/04\/007fuelinjection.png\" alt=\"007fuelinjection\" width=\"405\" height=\"304\" srcset=\"https:\/\/www.solopcms.com\/blog\/wp-content\/uploads\/2014\/04\/007fuelinjection.png 405w, https:\/\/www.solopcms.com\/blog\/wp-content\/uploads\/2014\/04\/007fuelinjection-300x225.png 300w\" sizes=\"(max-width: 405px) 100vw, 405px\" \/><\/a><\/p>\n<p>The latter is used in my car and works more efficiently as there&#8217;s a fuel injector in<br \/>\neach cylinder of the car. This provides a faster and more efficient response over<br \/>\nsingle-point fuel injectors.<\/p>\n<p>As for the magic behind how fuel injectors themselves work, they&#8217;re actually so<br \/>\nsimple that even I can understand how they work without having to study much<br \/>\nabout how cars work. When you step on the pedal, the ECU tells your fuel injector to<br \/>\nopen. Pressurized fuel spurts out into your cylinder in precise measurements that are<br \/>\ndetermined by the ECU&#8217;s pulse width.<br \/>\nThe worst part about my story is that the mechanic I told you about really was trying<br \/>\nto rob me. After learning about fuel injectors, I took it to another more reputable<br \/>\nmechanic whom owned his own little \u201chole int eh wall\u201d shop to receive a quote that<br \/>\nwas a fraction of the first guy&#8217;s price.<\/p>\n<p>My new and more trustworthy mechanic told me that my fuel injectors weren&#8217;t bad,<br \/>\nnor did <a href=\"https:\/\/www.solopcms.com\">ECU repairs<\/a> need to take place. All he had to do was find one of the many<br \/>\nsensors involved in the fuel injection process and replace it.<\/p>\n<p>I asked him what sensors were involved with my fuel injection systems and he told<br \/>\nme that there were almost as many different sensors in my car as there are types of<br \/>\nshoes for people to wear. There&#8217;s one that detects how much fuel is flowing through<br \/>\nthe system, one that detects the throttle position, another for the voltage and<br \/>\nanother that monitors the manifold&#8217;s pressure.<\/p>\n<p>He started to explain each one to me and how it worked, but I told him that he&#8217;d<br \/>\nalready told me enough to gain my trust. I told him to replace the oxygen sensor,<br \/>\nand that was the best decision I&#8217;d made. Not only did that fix my car&#8217;s woes, but it<br \/>\nalso didn&#8217;t make my purse that much lighter.<\/p>\n<p>It just goes to show you that there are still people who will try to take advantage of<br \/>\nme just because I&#8217;m a woman. At least I&#8217;m able to say that I understand how one<br \/>\npart of my car works and to know when someone&#8217;s trying to pull the wool over my<br \/>\neyes.
