Abstract
A control system for an internal combustion engine is described which allows the engine to be started and stopped while unloaded. The invention incorporates the mechanical linkage operated by a solenoid to control a valve at the interior of the engine and an electronic circuit incorporating one or more time delay relays. The invention provides a means of reducing or eliminating the source of vibration resulting from the starting and stopping of a single cylinder diesel engine. Several embodiments are described including one incorporating an integrated circuit timer and one incorporating two time delay relays.
