Hole to Hole Mass Distribution in Diesel Injector (English)
Abstract [sv]

Olika exemplar av common railinsprutare har testats i avseende på fördelning av bränsle över

insprutarens åtta hål. Mätutrustning har konstruerats för att samla upp varje bränslestråle var för

sig i varsitt provrör som sedan vägts.

En stor del av arbetet bestod av konstruktion av mätutrustningen och anpassningar för att kunna

utföra mätningarna så noggrant som möjligt.

Tre olika insprutare av samma modell och en insprutare av senare modell testades för två olika

driftspunkter och resultatet jämfördes med tidigare uppmätta värden för rökemissioner.

Ytterligare sex insprutare testades för en driftspunkt. Samtliga insprutare visade upp hål till

hålvariationer i olika stor utsträckning. Sammantaget av alla tio testade insprutare så kan enbart

hål till hålvariationerna inte förklara skillnaderna i rök.

Abstract [en]

Different examples of common rail injectors have been tested, referring to fuel distribution over

the injector’s eight nozzle holes. Measurement equipment has been constructed to collect each

fuel spray separately in one test tube each, which then will be weighed.

A big part of the work has been constructing the measurement equipment and adjustments to be

able to do the measurements as accurate as possible.

Three different injectors of the same model and one injector of a later model were tested at two

different load points and the results were compared with earlier measured smoke emissions.

Another six injectors were tested at one load point. All the tested injectors showed hole to hole

variations of different size. Summarizing the test results for the ten injectors, hole to hole

variations can not alone explain differences in smoke production.
