Abstract

Official abstract text for this publication.

There is provided an engine stroke determination apparatus. The engine stroke determination apparatus is for determining stroke of a single-cylinder four-stroke engine and includes a transistor igniter. The apparatus is configured to determine a compression stroke and an exhaust stroke by comparing voltages of ignition signals that are output in the compression stroke and the exhaust stroke by the transistor igniter.

First claim

Opening claim text (preview).

The invention claimed is: 1. An engine stroke determination apparatus for determining a stroke of a single-cylinder four-stroke engine, the engine stroke determination apparatus comprising a transistor igniter, wherein the engine stroke determination apparatus determines whether an engine stroke is a compression stroke or an exhaust stroke based on a change in a number of an event or events in which a voltage of an ignition signal that is output in the compression stroke and the e…
