The main difference between the two systems is that mechanical fuel injection systems use mechanical devices to meter the correct amount of fuel into the engine. Mechanical fuel injection was developed before EFI and paved the way for EFI technology to be developed. The fuel injectors themselves open to let the atomized gas directly into the combustion chamber or into a throttle body. The overall volume of air entering the engine along with the optimal air/fuel ratio decided by the manufacturer gives the electronic control unit (ECU) enough information to calculate the exact amount of fuel the engine needs. This sensor tracks how much air is entering the engine at any given time. The fuel pressure regulator knows how much fuel to let through to the injectors via a signal from the mass airflow sensor (MAF). The fuel pressure regulator constricts the flow of fuel and only lets a calculated amount through to the injectors. It travels through fuel lines towards the engine. The fuel exits the fuel tank via the fuel pump. It follows a fairly straightforward process to do so: Electronic fuel injection (EFI)Įlectronic fuel injection allows for extremely precise control over how much fuel is sprayed into the cylinders.

There are a number of different fuel injection systems out there, but they can all be sorted into two categories: mechanical fuel injection and electronic fuel injection. Emissions are easier to control as well, and fuel economy is boosted with more efficient fuel delivery. Fuel injected vehicles drive more consistently and required servicing and tuning significantly less often. Once manufacturers were required to develop more efficient carburetor designs and manufacture more complex parts, the cost of producing carbureted vehicles was great enough that fuel injection became the more cost-effective solution.įor consumers, this was actually great news.

A series of oil shortages in the 1970s forced the government to regulate vehicle fuel economy. Fuel injection offers a number of advantages over carburetion, but it was ultimately production cost that killed the carburetor.įor quite a while, carburetors were the simplest and cheapest way for car manufacturers to deliver fuel into the cylinders of their engines.

What did fuel injection replace?įuel injection systems were offered as an upgrade from carburetors when they first came out, and they remained in that role until the 1980s when they started becoming standard equipment on every new vehicle. Cars today are more dependable and more accommodating to creature comforts and occupant safety than anyone could have imagined a century ago. By the turn of the 21st century, people were groaning at traffic traveling only 60 miles per hour on the highway. At the turn of 20th century, it was incredible for a vehicle to travel 60 miles per hour. The rise of fuel injection was as predictable as the rise in popularity of cars themselves. Modern cars use electronic fuel injection systems that are controlled by the ECU. Unlike carburetors, which rely on the vacuum created by the engine to draw fuel into the cylinders, fuel injection systems precisely deliver a consistent volume of fuel. Fuel injection has since become a standard feature in every new vehicle.įuel injectors atomize gas, allowing for more even and consistent ignition in the combustion chamber. As engines evolved throughout the twentieth century, there came a point where carburetors became the weakest link in the drivetrain in terms of efficiency and dependability. All of the air you can forcefully induce into the cylinders will do nothing without an appropriate amount of fuel to burn. When it comes to engine performance, there are few things more important than fuel delivery.
