ABSTRACT:
There are disclosed a method and an apparatus for measuring an injection amount per injecting from an injection device for use with an internal combustion engine. According to the invention, pressure within an injection chamber for measurement is preliminarily raised to predetermined pressure before injecting of the injection device, and then fuel oil is injected from the injection device into the injection chamber with the raised pressure. An increase of a volume of fuel oil within the injection chamber causes displacement of a piston of a displacement member. By using an amount of displacement of the piston, an injection amount of fuel oil from the injection device per injecting can be measured with high accuracy by reducing a measurement error due to a compressed volume resulting from the pressure increase.
