How do Diesel fuel injectors work? Piezo common rail diesel fuel injector operation explained
Diesel Piezo fuel injector animation with explanation of how it works. In this animation I talk about how these Diesel fuel injectors work and the number of pre and post injections.
These injectors typically operate between 1600 bar and 2700 bar depending on engine and high pressure fuel pump. The Bosch Piezo injector injects into the cylinder the amount of fuel required for economical combustion, independent of the driving situation.
The third-generation high-performance piezo injectors enable a high degree of freedom when designing the injection characteristic and allow up to ten individual injections per injection cycle. up to 2,700 bar pressure for very high motor performance with low consumption low fuel consumption and reduced emissions are made possible through extremely short injection intervals. up to ten individual injections per injection cycle for quiet and highly efficient combustion.
The injector is permanently supplied with fuel from the rail via the high-pressure connection. The injection process is initiated by the control unit via the electrical connection. The return flow quantities arising during the injection process flow back to the tank via the fuel-return line.
Piezo injectors made by Bosch are available for pressure levels between 2,000 bar and 2,700 bar. They are used for the premium car segment and in light duty vehicles. The injectors have a modular construction and can be adapted to the customer's needs. The variants tailor-made for each application scenario differentiate themselves with regard to, for example, lifetime, nozzle design, and injector length.
As the piezo actuator is integrated in the housing, the injectors are significantly slimmer than solenoid valve injectors and thus require much less installation space.
Thanks to their robust piezo principle, the injectors are well prepared for different fuel qualities. The rapidly switching CRI3 piezo injector allows short injection intervals which inject into the cylinder the amount of fuel required for economical combustion, independent of the driving situation.
Up to ten individual injections are possible per injection cycle. In addition, the injection process can be designed with high flexibility. Using multiple injections, the engine's fuel consumption and CO₂, pollutant, and noise emissions can be reduced. Control is via a piezo actuator made of several hundred layers of a piezo ceramic. The ceramic expands by a few thousandths of a millimeter as soon as voltage is applied, setting the jet needle in motion. This coupling of actuator and nozzle needle enables the very short reaction times and very small preinjection quantities.

A dual-clutch transmission (DCT) (sometimes referred to as a twin-clutch transmission) is a type of multi-speed vehicle transmission, that uses two separate clutches for odd and even gear sets.

    Any video talking about a pre purchase inspection that doesn’t mention bore score, is a useless video in my book. Both 987.1 and .2 are at high risk of developing bore score, people think that 987.2 is immune to bore score, but they are delusional, it’s just taking .2 cars longer to reach their failure point because they are newer. The only cars which are relatively immune to bore score are the base models because they have forged pistons, and produce less heat in general. The rest of the items are pretty easy cheap to fix, there are after market cable ends, to replace the worn ones, I’ve done them and I have 400,000km on my car’s original cables. They will NOT easily break if you’re not brutal with them. The half shafts have an issue with rust for sure, I’ve replaced inner and outer x4 boots twice. One half shaft wore on the inside and replaced it with a used one. They last a very long time there’s no point of spending $1500 on a new one. The AOS is a DYI that cost under $100. I would do it preemptively every 100,000 km. My advice NEVER buy these cars without scoping all 6 cylinders for scoring.

      Hey, is this a problem with your car or just a general question on what causes the boost air to be hot. As the turbo is connected to the exhaust naturally there’s heat transfer. Secondly, when you compress air it heats up, hence why it’s common to have an intercooler.

    Hello! What could be to blame?! After a whole night, at 7 in the morning, when I put the tester on, the outside temperature is 8 degrees Celsius, but the antifreeze temperature is 13-15 degrees Celsius. When starting for the first time with the outside temperature between 5 and 15 positive degrees, after starting, if I try to accelerate, the engine speed fluctuates very badly. If the start-up takes place at outside temperatures below 5 degrees or above 15 degrees, then everything is ok!

I assume you have a fault code reader to check? fuel filter, when was that last changed? Dirty fuel filter can cause mystery running issues. Any fault codes for the glow plugs? If one of those isn’t working correctly that will cause running issues first thing. Also what is the intake air temperature? You should have a few temp sensors to check between.
