Is warming up essential from cold start?

[axy]

I run my acoot most days to work, it costs me around £5-£6/week on fuel but if i run my Mazda turbo diesel hatchback it costs me £25/wk, and thats just on fuel alone. Factor in Insurance, taxes, tyres, servicing and parts and i estimate that over the year i save a minimum of £1000, easily. I only run a 50cc Agility tho.

Just read this arcticle, compares car use to scooter, pretty interesting. http://scooterunderground.ca/knowledge/ScooterPollution.htm

Yes, I believe you have calculated that correctly. If your choice of vehicles was different, it could easily be vice versa.
For example, if you drove 500 cc scoot vs. small turbo diesel car (entry level of any European manufacturer), I think scoot would lose the game...

There are maximum emission limits (like "Euro X") and (usual much lower) individual emissions (from EU type approval, i.e. published by www.kba.de). 2 examples from our KBA:
Piaggio MP3 LT500 (AIQ): CO 0.333g/km, HC 0.009g/km, NOx 0.030g/km
Toyota Prius 2 (ACI): CO 0.180g/km, HC 0.020g/km, NOx 0.010g/km
There is not very much difference between a modern (fuel injected) scooter and a modern hybrid car. Of course the Prius is heavier and can carry more, it has the far superior technology. But is it better for the environment?

I drive a Prius and ride an '06 People 250.  The Prius has very tight emmissions controls and even at cold start smells much cleaner than the People.  The People has a carburator and no catalyzer.  I've been getting about 55 MPG with both vehicles when driven at the same rate.  The Prius emmissions are much lower than the People's.
The maintenance on the People is MUCH higher and more expensive than the Prius.  So much so that I do it myself to make the price more palatable.  All this said, I love the scoot' and know that it is much cleaner than a large percentage of the vehicles on the road here in the States, primarily because of the high percentage of SUV's and pick ups.

Which do you think pumps more air through it, a 50cc scooter cruising at 50mph or a 4 cylinder car cruising at 50mph? I'll bet the scooter is pumping more air.

Although there is no street legal 50cc scooter which can cruise at 50mph, I bet against.
When I cruise with my wifes MP3 LT250 between the trucks on the Autobahn, I need 3-3.5 litre/100km (78-67mpg). Our small car needs at minimum 5-5.5 litre (47-43mpg). As both are fuel injected, running with electronical comtrolled lambda=1, the scooter needs less air.

Let's compare 50 cc scooter cruising at 40 mph (50 mph stock would be impossible except for Italian 50 cc 2 stroke scoots w. 5.5 hp engines) and 4 cyl car at 40 mph.

Scooter would consume around 2-3 l/100 km. Car would consume around 5-6 l/100 km. Car would require roughly twice more air.

However, try comparing efficiency per hp: 4-5hp vs. 60-120 hp. Suddenly, it seems that car consumes 7-15 times LESS air per hp.

Or, if you go by weight, 100 kg vs 1200 kg kerb weight, car consumes 6 times LESS air than scoot based on carried weight.

Etc.

Now my friggin' head hurts.
Operating rpms factor in as well. The whole carbon footprint track is a huge factor. Fuel quality plays a role, as well as oil used for that matter.
HUGE topic!
So to answer the question of warm up... Burn the scoot, and get a skateboard (made of dirt)! Or walk...

Where did air pumping come from?
