I’m often irritated by drivers of diesel vehicles who seem to think it’s a good idea to leave their engine running for ages when parked.
These things are left idling by taxi and delivery drivers for all sorts of old-wives’-tale reasons (sometimes just to keep their vehicle heaters operating on a cold day). The fact is that they pump out huge amounts of toxins, particulates and noise that I really don’t need.
So, today’s invention is a simple switch which cuts off the fuel supply to a diesel engine left idling for more than a couple of minutes.
