You may have heard someone referring to the Detroit 8.2L as a fuel pincher, then you think why? Let me tell you the reason.
The Detroit 8.2L is called a fuel pincher because of its ability to save fuel, or simply put, it is fuel-economical.
There are different models of Detroit engines, but when it comes to fuel reservation, the Detroit 8.2L takes the lead. It is on this note that it is commonly found in school buses, marine, and other applications.
Let’s dive into the fuel system to know why it could be able to maintain 100% fuel efficiency.
The engine uses unit injectors; these injectors perform the following functions:
1. Measuring: The injectors are responsible for measuring adequate fuel to each cylinder according to the calibration of the injectors. The measurements are needed so that the fuel supply will not be too much or too small. The fuel must be enough to burn the compressed air. But if too much, it will cause a rich air/fuel mixture, which causes incomplete combustion.
2. Timing: The fuel timing is also done by the injectors. The injectors must inject the fuel at the right time. This means the piston must be at the TDC when the injectors of that cylinder are atomized. So the injectors are injected according to the firing order, which refers to the injection timing.
3. Atomizing or injecting: This is another role performed by the injectors. It injects pressurized fuel into the combustion chamber. The pressure or the fuel bar measured in psi must be by the manufacturer’s prescription.
At this point, let’s talk about the fuel pump. The fuel pump is a mechanical fuel pump, which means it is controlled by the engine, not electric. The fuel pump is a single fuel pump that supplies the fuel to the common rail of the cylinder head. Then, from there, the fuel goes to each injector in turn to keep the engine running.
The fuel pump receives fuel from the fuel tank and supplies it to the injectors with some adequate pressure. But before the fuel gets to the injectors, there is a fuel filter that filters the fuel to prevent dirt from getting to the injectors.
The injectors are controlled by the camshaft. The camshaft actuates the rocker arm, which in turn actuates the injectors so that it can keep the engine running.
So the Detroit 8.2L is referred to as a fuel pincher because of its high level of fuel efficiency.
The above-mentioned components and system are what help it to run smoothly and efficiently.
