Over time, vehicles have had noticeable changes in their appearances, along with their mechanical designs. Unknown to most, however, this was due to events that would take place in the 1970s, which would directly affect the future.
With the oil crisis in 1973, fuel efficiency would become the main focus of vehicle development. This would mean lighter cars, smaller engines, and More emissions equipment. These strict emission rules would mean the development of two emissions equipment, named the EGR, and Smog. The EGR (exhaust gas recirculation valve) would direct exhaust glasses back into the engine for re-burning, while the smog pump would work alongside it, pumping fresh air into the exhaust. Catalytic converters were also strictly enforced during this time, making almost every single car come with one or more, built into its exhaust system. But unlike other equipment, however, emissions would need more monitoring/control.
By combining the new electronic ignition systems with the new emissions, computers would be used to control both. This would allow for the first “Electronic fuel injection” systems to be used, soon taking over in the late 80’s, and early 90’s. This new computerized engine management would drastically increase efficiency, as well as lower emissions due to more accurate fuel rates, making the computers increasingly popular. This became extremely popular, directly allowing for more complex and developed computers to be used like they are today, allowing for more computers, and more features. Anti-lock brakes, Airbags, traction control, radios, HVAC, windows, and locks would now be all computer-controlled. For engine management, this was also because of the more accurate control, and turning cars what they are known for today. Up to 100 computers can be found in today’s vehicles, making them more technically advanced than ever, with future cars wanting to reach the 200 computer mark.
