When it is freezing and I start my car and walk around it I can smell the unburnt fuel from the exhaust. Such a waste, but what to do?
What about electrically heating the intake air?
It needs to be electric; the exhaust manifiold is still cold too at first.
Laid my egg, now shoot  |
My Subaru 360 which is exhaust heated only (aircooled motor) gets heat in around 90 seconds, so I would lean toward just routing by the cat and manifold first.
Also for instant heat...
You could just preheat the gas tank to 150 degrees F
(it works too but is rather dangerous, I did it carefully one time and it has MASSIVE affects in cold weather on warm up time, timing, FE and the whole 9 yards) Had a lot more power off the line as well. As a side note, most fuel systems are rated to 140-160F so you can run a car in a desert safely.
