Abstract
A method and apparatus for controlling the speed of an engine having a plurality of cylinders and a compression brake operable on one or more of the cylinders is disclosed. The method includes determining a speed of the engine, comparing the engine speed to a first threshold, and activating the compression brake for at least one of the cylinders in response to the engine speed exceeding the first threshold.
Claims11
An apparatus configured to control the speed of an engine having a plurality of cylinders, the apparatus including a compression brake, operable on at least one cylinder of the engine, comprising:
- a speed sensor adapted to sense an engine characteristic indicative of an engine speed and responsively generate an engine speed signal;
- and
- a controller configured to receive said engine speed signal, compare said engine speed to a first threshold, disable fuel injection to each cylinder in response to said engine speed exceeding said first threshold, and activate said compression brake for at least one of the cylinders in response said engine speed exceeding said first threshold.
A method of controlling the speed of an engine, the engine having a plurality of cylinders, and a compression brake operable on one or more of the cylinders, comprising the steps of:
- determining a speed of the engine;
- comparing said engine speed to a first threshold;
- disabling fuel injection to each cylinder in response to said engine speed exceeding said first threshold;
- and
- activating said compression brake for at least one of said cylinders in response to said engine speed exceeding said first threshold.
