Showmedo is financed by a subscription club, membership of which grants access to all of our 160+ specially produced videos. These include our 50 video introduction to Python programming, and our recently completed Open-office migration collection.
(Showmedo is undergoing major changes. To
report any problems viewing the videos please
email us and include
browser and OS specifics. Cheers - Kyran.)
The purpose of this demonstration is to isolate the problem
preventing an engine from starting. The video explains how we can tell
the battery is ok (because it is able to power a motor that rotates the
engine) suggesting the problem lies in ignition and/or fuelling
mixture. The requirements of internal combustion are:
Fuel (petrol or diesel)
Ignition (spark on petrol engines, glow plugs and compression on
Mixture (of the fuel and air, in correct proportions)
Compression (of the fuel/air mixture)
Engine rotation causing compression, either by push starting,
starter motor or engine already running
Compression almost always fails during operation (e.g. blown gasket).
Mixture usually fails slowly, due to lack of maintenance, or if the car
has not been driven recently. Air is available unless blocked. The
video shows how electrical supply can be confirmed (using dash lights)
suggesting that ignition is possible, and further, how to confirm
engine rotation and by implication, battery health.
Are you learning Python? To keep the site running clean and ad-free we've started Club ShowMeDo. The club will allow you access to some special videos we're making to pass on programming skills we consider important to the development and enjoyment of Free Open Source Software (FOSS).
The focus at the moment is on developing with the Python programming language, one of the backbones of the FOSS movement with a huge number of included and third-party libraries.
We welcome feedback and we want to hear your ideas.
Showmedo's development is fairly rapid and bugs will inevitably creep in. If you have any problems please drop us a line using the contact address below. Likewise, any suggestions for improvements to the site are gratefully received.
