This is a question The Dirty Secrets of Your Trade

So, Television is a hot bed of lies, deceit and made up competitions. We can't say that we are that surprised... every job is full of this stuff. It's not like the newspapers currently kicking TV whilst it is down are all that innocent.

We'd like you to even things out a bit. Spill the beans on your own trade. Tell us the dirty secrets that the public need to know.

Emissions trickery
I work in engine and gearbox development for a nameless car manufacturer.

We were fairly convinced that we wouldn't be able to make one of our engines pass the latest round of stringent emissions tests. That is, until one of my colleagues demonstrated a fairly crafty trick...

In essence, what we've done is to divert some of the air directly from the air intake into the exhaust tract, bypassing its route through the engine completely and 'diluting' the exhaust gas. Daft as it sounds, it worked, and that's how that engine's been made for at least a couple of years. It now passes the test, despite not actually producing any fewer pollutants than it did before.
