what exactly does this mean for a cars engine???

Question

6 Cylinder 24 Valve 2.5 Liter Miller Cycle Supercharged DOHC Engine


Im a girl buying a car. no clue what this means.

I owned a chevy cobalt ss supercharged before and traded it for a ponitac GTO. pontiac was amazing tons of horsepower loved it. going to buy another car but i dont understand what that means.

Thanks in advance :)

Answer 1

6 cylinders in the engine
4 valves per cylinder (2 intake & 2 exhaust)
2.5 liter is the engine size
Miller Cycle??? dunno what that is
Supercharged means that a device (supercharger) forces air into the engine for better performance
DOHC = Dual Over Head Camshafts which means there is a camshaft in each cylinder head and it's at the top of that cylinder head. Some cars only have one camshaft and it is usually located in the middle of the engine.

Answer 2

Miller Cycle is technology which incorporates what is sometimes call a 5th stroke. We had these in our Mazda Millenia's until they discontinued the car in 2002. This technology changes the valve's timing and is designed for supercharged cars.

The above answers pretty much described the other parts of your question correctly.

Answer 3

All of the above. It just mean very high tech engine.

24 valves = 4 valves per cylinder. most cars have 2 or 3 valves per cylinders.

Supercharger. Most car are "nomally" aspired or breath without any super / turbo charger.

DOHC = most car will have single over head cam system

===
High tech mean high maintenance - don't forget


Good Luck

Answer 4

All of the above answers except DOHC means there are four cams, two on each head. One cam for the intake valves and another for the exhaust valves.

Answer 5

Actually, it's 2.0L of air and fuel mixture for all the cylinders combined. So a 2.0L 4 cylinder means each cylinder holds, at its MAX volume, 0.5L of air and fuel mixture. Basically the more air is drawn into the cylinder, the more fuel can be burned. So with a bigger piston or a longer stroke, it can draw more air in, and thus burn more fuel to make more power. Also, the ideal ratio of fuel and air is 14.7lbs of air per minute for every 1lb of fuel. Now, 1 gallon of fuel is about 8.6lbs. And most engines take about 1lb per minute of air to make 10hp.

Answer 6

6 cylinder= cylinder where air and gas mix and explode
24valve= 4valves each cylinder/ 2 to get air in 2 to get air out
2.5liter= total air volum in all the cylinders
Supercharged= forces mora air in your engin; more power
DOHC=Dual overhead camshaft http://en.wikipedia.org/wiki/DOHC#Dual_overhead_camshaft

Answer 7

That is an internal supercharger. Stay away!!! If it fails, the part is (was) $3500! No labor, just part. Yikes!!!
