There are a few threads on here about diesel engines and fuel injection. The search function will bring them up. Here are a couple...

Not noticeably as the guide bush, but it only runs a few minutes per needle. If you were making a V16 it might be something to consider.

Thank you Chris, The machining sequence for these needles took a little experimentation. The bore in the nozzle is 1.4mm. This needs to...

This is a drawing of a mushroom type injector. The only precise piece is the cone and seating. It also doesn't need a leak off pipe...

Yes the bore is nominally 1.98 mm. The piston is a piece of 1.98 mm pin gauge.

Hello Chris, I have two engines running with petrol injection using 2 different injection pumps. The first is a 25cc four stroke using...

Hallo Ruben, I don’t really know what the clearance is, I don’t have an accurate means of measuring it. It is certainly less than 0.01...

I was thinking about your fuel volume control using an additional spring loaded plunger set in the side of the injection pump barrel...

Hallo Ruben, As ever this is complicated. I initially tried cheap ‘hobby’ small drills but they were generally badly ground and did not...

There is quite a lot of effort involved in drawing good plans and writing up the details even for quite a small item like this. I do...

The car was made many year ago, mostly from various scrap bins. It has a Parvelux 24 V DC gear motor and controller from a cancelled...

I like to load test my engines, all the spark ignition ones are coupled to a DC motor as a generator (also as a starter). I have a...

Hallo Ruben, That pump is designed for petrol injection into the inlet of a spark ignition engine. If you are looking to build a...

To complement this thread I have posted about my injector test pump here...
