MOTORPAL Jihlava is a very important manufacturer of fuel injection devices for diesel engines.

Among others it also manufactures a whole range of injection nozzles, the catalogue of which is presented here. MOTORPAL injection nozzles are so-called closed nozzles, consisting of a body and a needle, which form an exactly manufactured unit with a tolerance of thousandths of a millimetre, the parts of which can therefore not be arbitrarily substituted.

Two basic types of injection nozzles are manufactured:

Pin nozzles – designated DC, mostly used in engines with indirect fuel injection (engines with pre-combustion chamber)
Hole nozzles – designated DO, used in engines with direct fuel injection (currently the most used type).
Injection nozzles are made in standard sizes, with various numbers of shot-out holes, various diameters and angles, in compliance with international standards.
