This study presents the development of an automatic motorcycle engine start-stop device
for a motorcycle engine. The pandemic year, 2020, caused a lot of vehicles to be
underutilized due to the implemented quarantine to combat the spread of the virus. This
resulted to motorcycles being prone to damages that are caused by long time of no usage
that can result to battery deterioration, engine failures, and hard start. The proposed device
aims to start the engine for 10 minutes when its program detected that the engine did not
start for 3 days. The features of the device are that it works automatically with less
requirements of the user’s inputs and it is independently powered by its own battery. The
device is tested for how long the motorcycle can be idled and still be started by the device.
It is tested for 4 hours, 1 day, 3 days, and 7 days of no engine ignition. Test results showed
that with a motorcycle left idle for three days, the device was able to activate an engine
ignition and engine shut down. The device was evaluated by 25 evaluators composed of
Automotive Engineering Technology professor and students under the College of
Industrial Technology of the Technological University of the Philippines and motorcycle
drivers. It was rated with an overall mean of 4.56 with a descriptive rating of “Excellent”.
This signifies that the device is useful for the motorists in terms of the Functionality,
Effectivity, Workability, Durability, Economy, and Safety.
