Abstract
Official abstract text for this publication.
Provided is an engine capable of performing post-injection control with a proper fuel injection amount. The engine ( 1 ) comprises an engine body ( 10 ) equipped with a turbocharger ( 7 ), an engine rotational speed sensor ( 21 ), an acceleration opening degree sensor ( 24 ), a boost sensor ( 23 ), a turbo sensor ( 22 ), and an ECU ( 100 ) for performing post-injection control. The ECU ( 100 ) recognizes the rotational speed of the engine, the supercharging pressure, the load on the engine, and the rotational speed of the supercharger, and so performs the post-injection control that the rotational speed of the supercharger becomes equal to the target rotational speed of the supercharger calculated in the ECU ( 100 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. An engine comprising: an engine body equipped with a supercharger; an engine rotational speed sensor which detects an engine rotational speed; an acceleration opening degree sensor which detects a load on the engine; a supercharging pressure sensor which detects a supercharging pressure; a supercharger rotational speed sensor which detects a supercharger rotational speed; and an engine control unit calculates a main injection amount from the…
