Handling of fuels and lubricants used when working with motor vehicle engines.

Demonstrations and exercises done by students on old motor vehicles may reveal asbestos products particularly as disc pads, brake linings, clutch linings and heat insulation around exhaust pipes.

This is a 'make-it' guide for constructing a DC motor from easily sourced components and 3D printed parts.

The 3D print files are available from GL365A listed below.

Products generated by the combustion of fuels are mainly carbon dioxide and water together with traces of carbon monoxide, hydrocarbons, nitrogen oxides, sulfur oxides and organic lead compounds.
