knowledge is a bit of a “how to” section where we will add pages explaining how we have learnt to do something or a quick method or just something we have learnt
The air intake system channels clean air and fuel to an internal combustion engine. The primary function is to channel clean and cool air to the engine. In indirect injection engines the fuel is added [more…]
When we talk about the engine ignition system there are two fundamental types: compression ignition spark ignition. This is the system for igniting an fuel-air mixture that has been compressed in the cylinder by the [more…]
The Lead Acid Battery is a battery with electrodes of lead oxide and metallic lead that are separated by an electrolyte of sulphuric acid. The overall reaction is: PbO2 + Pb + 2H2SO4 <=> 2PbSO4 [more…]
In a rechargeable lithium ion battery lithium ions move from the negative electrode to the positive electrode during discharge, and back when charging. The cathode is a lithium transition metal oxide, eg manganese or cobalt [more…]
A device for generating steam for power, processing, or heating purposes or for producing hot water for heating purposes or hot water supply. I’ve included the firebox within the overall steam boiler as it’s difficult [more…]
This page lays out some of the crankshaft design principles along with descriptions of the main features. That part of the engine which transmits the reciprocating motion of the pistons to the driven unit in [more…]
The wheel on the end of the crankshaft that gives the crankshaft momentum to carry the pistons through the compression stroke. Normally constructed from a heavy steel or iron disc. A flywheel has two main [more…]
I was reading an article about using a fuel cell energy storage system for a drone and how it was a high energy density option. This made me wonder how a fuel cell works and [more…]
The Stirling engine is an external combustion engine. Also known as a Hot Air Engine. The Stirling engine was invented in 1816 by a Scotch clergyman, Robert Stirling, as a competing technology to the steam [more…]
I’ve been looking into the angle of the steam boiler on a traction engine relative to the surface that the engine sits on. This angle is always biased downwards towards the firebox. Having measured a [more…]
