Why is injector and pump tester maintenance important

22 Sep 2024

Over the past few years, there has been a rising demand for efficient fuel injection systems which provide cleaner engine emissions, improved power, quieter operation, and of course, most importantly, efficient injector tester machine is good for economic fuel consumption.

However, it is of utmost importance to keep your fuel injector and pumps well-maintained and clean.

Today we will discuss the importance of maintaining fuel injectors and pumps as well as their function and importance. We will also cover the types of fuel injection systems and the pros and cons of each and every one of them, as well as buying injector and pump tester machinery to continuously monitor and maintain these systems to make sure they run smoothly in order to optimize engine performance via the effective distribution of fuel into the cylinders of the engine.

Why is injector and pump tester maintenance important?

The function of fuel injector and pump is quite complex. They deliver fuel to the engine of vehicles or other machinery so that a spark plug can start it.

This is why fuel injectors deal with high levels of heat and pressure. Sometimes, the burning fuel leaves residues on the piston and injection nozzle heads that might accumulate with time and cause damage. Such damages often cause spray patterns to be ineffective and thus reduce the proper flow of fuel to the engine.

The 4 Types of Fuel Injection Systems

There are four different types of injection systems used to adjust the engine’s RPM (Revolutions Per Minute).

The role of these systems is to adjust the amount of air and fuel inserted into the cylinder and each system accomplishes it differently.

Single-point throttle body injection

This was the earliest injection system, and it was a building block for more complex systems to come. Even though it is not as precise as other injection systems, it is however the simplest and the most cost-effective.

Port multipoint fuel injection

This CRS1000 is more advanced than the single-point.

The advantage of this system is that fuel is more effectively sprayed into the engine, which reduces performance problems.

However, it does have one disadvantage, which is just like the first system, this system works at one time. In other words, fuel will be sprayed into the cylinders even if one of them is in the combustion phase, which is wasteful.

How do you diagnose a bad fuel injector?

When an engine does not start or stalls or vibrates, it can be an indicator that the fuel injector has gone bad and thus needs maintenance.

What is a Fuel Injector Test bench?

A Fuel injector common rail test bench is an environment used to test the correctness of a fuel injector. This is normally done by an injector and pump tester.

How do you test HEUI injectors?

A Hydraulic Electronic Unit Injector (HEUI) is a system computer-controlled that consists of a combined pump and injector for each cylinder inside the engine. In order to test HEUI injectors, you will need special equipment.
