So The old 658cc pigeon diesel said it had a carbureted intake. Can diesels be carbureted in real life?
since diesels work off compression ignition, that is to say they rely on the piston compressing the charge, thus heating it and causing it to detonate, there's no way to have accurate control over precisely when the mixture will detonate, since with each intake cycle there could be slightly more air sucked in, resulting in higher density, or the outside temperature may be higher, meaning the combustion temperature threshold is reached earlier. so instead, they work using some kind of fuel injection (either direct, or indirect, where you have a precombustion chamber) to precisely control when the fuel is sprayed into the engine, and thus when the charge will detonate, as they can heat the plain air way past the point which an air/fuel mixture would combust. so no, carbureted diesels don't really exist, and if the pigeon were to have an accurate diesel, it would likely be a mechanically driven direct injection system.
so yeah i can see that being one of the reasons why they got rid of the 658cc and replaced it with the 550cc. like really can you imagine a wigeon with a 658cc diesel stock?
