In a conventional gasoline engine (PFI or SIDI) fuel and air are largely pre-mixed before the spark event (which controls the start of the combustion process) which then leads to a fast ...

Then there are the normal by-products of an internal combustion engine: soot, metal wear particles, old oil residue breaking down, etc. The oil filter elements are designed to collect as much of this detritus as possible without hindering free oil ...

The real reason for dual mass is simply to add additional revenue to manufacturer supported workshops, since the ...

I suspect you've already answered your question. I assume that the garage is largely un-ventilated and that you promptly close the doors upon leaving for work. I'd be very tempted to, next time the weather is slightly windy, leave the doors open for a few hours to let the garage air out. Out of interest, do you reverse into the garage so the cars exhaust ...
