SSDR with an automotive diesel engine
Toying with the notion of a SSDR (deregulated sub 300kg microlight) powered by a small diesel engine from a standard car.
Diesel engines have a simpler ignition system in that they use the compression stroke to ignite the burning fuel. Diesel has a higher flashpoint and is cheap than MOGAS and AVGAS especially if duty free (red diesel in the UK) fuel.
Diesels are heavier by design which would make tight tolerances for ensuring adherence to the sub 300kg regs.
As it is merely a thought I'd be interested to hear opinions. It may be a non starter (pardon the pun) but thought it would be interesting to discuss.
Most modern diesels have some form of turbo compression and the deregulation removes a lot of the headaches associated with engine choices - but this is largely a hypothetical discussion initially.
