How does the Komatsu fuel injection system work?
How does the Komatsu fuel injection system work?
The Komatsu injection system is designed to form a fuel-air mixture by fuel injection. The fuel system works as follows. When the ignition is switched on, the fuel pump pumps the fuel into the system. When passing through the fuel filter, it is cleaned.
How to troubleshoot a Yanmar diesel injection pump?
Poor adjustments of the governor and bad fuel timing can mimic injector pump problems and should be eliminated as possibilities before tackling the injector pump. Check the fuel level in the tank. Ensure that the fuel level is sufficient to cover the fuel pickup and prevent any air from being drawn into the system in the fuel tank.
Why do I have a problem with my fuel injection pump?
Fuel injection problems, therefore, are one of the most pressing engine issues to deal with. Whether you’ve experienced fuel injector failure or not, it helps to understand the fuel injector pump, how it relates to engine performance, and also how diesel fuel injection pumps differ from traditional gasoline-powered units.
How is fuel delivered to the injector pump?
Fuel is delivered to the injector pump by a low pressure feed pump (lift pump). The injector pump draws fuel from the feed supply and distributes high pressure fuel to the injectors and the spill circuit. Air leaks and fuel restrictions reduce the amount of fuel that the lift pump delivers to the injector pump.

How did the Komatsu construction company get its name?
The original KOMATSU COMPANY was founded in 1917 in Komatsu, Ishikawa; which it was named after. After tremendous growth in the east it began to broaden its market to include European and eventually global production. Now, Komatsu is the world’s second largest manufacturer of construction equipment and mining equipment after Caterpillar.

How does fuel get out of the injection pump?
The fuel is dispersed from the injection pump to the combustion chamber via a fairly simple process. Pressurized fuel enters the fuel injector. Based on a signal from an electrically controlled solenoid valve – the solenoid valve acts as a type of on / off valve – the fuel enters a plunger, which prepares the fuel for the final exit.
How much psi does a fuel injector pump use?
Around 15-20 years ago, it was common for fuel injector pumps to process fuel in a system at around 10,000 to 15,000 psi (pounds per square inch). But that’s only about half of what engines are expected to do today.

What causes a diesel fuel injector to fail?
99% of diesel fuel injector failure can be traced to two different issues: • Faulty mechanical problems in the physical fuel injector housing. • Fuel quality (or rather, lack of quality) From these two things, a host of problems can surface.
