I know how long it will take Google to give you the answers so lets see how quick you can answer the following
Technical General Knowledge Quiz !
Q1. What is measured in "Dwell" ?
Q2. When is an inlet valve at its most open - ATDC or BTDC ?
Q3. What is the formula for cubic capacity ?
Q4. What is "overlap" in reference to a camshaft ?
Q5. What is 1 bar in psi ?
Q6. In relation to a 175/70 x 13 tyre and a 185/60 x 13 tyre @ 30mph what is the effect on the speedo reading (consider a 175/70 will read 30mph) ?
Q7. Does a brake adjustable bias system increase or decrease brake fluid pressure in relation to the front brakes ?
Q8. Does anti-freeze increase or decrease the boiling point of engine coolant ?
Q9. What is meant by Hydroscopic ?
Q10. Why is a vehicle fitted with a differential unit ?

Thats 3 minutes !
I know how long it will take Google to give you the answers so lets see how quick you can answer the following
Technical General Knowledge Quiz !
Q1. What is measured in "Dwell" ?
Rotation of cam
Q2. When is an inlet valve at its most open - ATDC or BTDC ?
ATDC
Q3. What is the formula for cubic capacity ?
Must be something like :
PI*(SQR(R))*STROKE
Q4. What is "overlap" in reference to a camshaft ?
When both valves are open for a short duration of time in cycle
Q5. What is 1 bar in psi ?
15
Q6. In relation to a 175/70 x 13 tyre and a 185/60 x 13 tyre @ 30mph what is the effect on the speedo reading (consider a 175/70 will read 30mph) ?
There will be a 4.2% difference i.e. If you are actually travelling at 30mph with a 185 tyre on, the speedo will read 31.25mph
Q7. Does a brake adjustable bias system increase or decrease brake fluid pressure in relation to the front brakes ?
It can do either, depends how you have it set
Q8. Does anti-freeze increase or decrease the boiling point of engine coolant ?
decrease
Q9. What is meant by Hydroscopic ?
can absorb moisture
Q10. Why is a vehicle fitted with a differential unit ?
Allow two driven wheels to rotate at different speeds

I know how long it will take Google to give you the answers so lets see how quick you can answer the following
Technical General Knowledge Quiz !
Q1. What is measured in "Dwell" ?
Time, ie time between tdc and beginning of atdc
Q2. When is an inlet valve at its most open - ATDC or BTDC ?
atdc
Q3. What is the formula for cubic capacity ?
Something like .7 or .8 x bore(cm) x bore(cm) x stroke(cm) x no. of pots
Q4. What is "overlap" in reference to a camshaft ?
Duration both valves are slightly open
Q5. What is 1 bar in psi ?
15 and a bit
Q6. In relation to a 175/70 x 13 tyre and a 185/60 x 13 tyre @ 30mph what is the effect on the speedo reading (consider a 175/70 will read 30mph) ?
Should be fairly equal.. poss a tad higher.
Q7. Does a brake adjustable bias system increase or decrease brake fluid pressure in relation to the front brakes ?
Pressure should be as is to front, pressure to rear should decrease if set for front bias
Q8. Does anti-freeze increase or decrease the boiling point of engine coolant ?
Raise
Q9. What is meant by Hydroscopic ?
Absorbs moisture
Q10. Why is a vehicle fitted with a differential unit ?
Allow both driven wheels to rotate at a different frequency

don't you mean "hyGroscopic" Dave? he he!

isnt a bar 14 psi?
I thought antifreeze increase the boiling point.
1 bar = 14.5 psi

NO ! :geek: !
As far as I am aware and can find in dictionaries, there is no word "hydroscopic." :geek: :geek: :geek:

its defo Hygroscopic
as in brake fluid aborbing water

I know how long it will take Google to give you the answers so lets see how quick you can answer the following
Technical General Knowledge Quiz !
Q1. What is measured in "Dwell" ?
The number of degrees rotation of the distributor that the points are closed
Q2. When is an inlet valve at its most open - ATDC or BTDC ?
ATDC
Q3. What is the formula for cubic capacity ?
Pi R sqrd x H (x number of cyls)
Q4. What is "overlap" in reference to a camshaft ?
The time that both inlet and exhaust valves are open
Q5. What is 1 bar in psi ?
14.8 psi
Q6. In relation to a 175/70 x 13 tyre and a 185/60 x 13 tyre @ 30mph what is the effect on the speedo reading (consider a 175/70 will read 30mph) ?
A 185/60 wil read higher than the car is travelling
Q7. Does a brake adjustable bias system increase or decrease brake fluid pressure in relation to the front brakes ?
It does NOT affect or touch the front brakes !
Q8. Does anti-freeze increase or decrease the boiling point of engine coolant ?
Increases boiling point
Q9. What is meant by Hydroscopic ?
Absorbs water/moisture
Q10. Why is a vehicle fitted with a differential unit ?
To allow wheels on an axle to rotate at different speeds
Hope this helped on some basic questions ?

He he Dave, you didn't answer Q7. A brake adjustable bias system does increase or decrease brake fluid pressure in relation to the front brakes.
Q10: A diff also allows the front and rear axles to rotate at different speeds - ask a Quattro (or Cosworth 4WD) driver.
A good effort anyway and I liked the idea. How about for the next one "what does castor, camber, and toe-in affect?"
I think this dwell question may just go on and on(or dwell on and on).
I too thought it was a measurement of time and/but to do with the ignition.
what does castor, camber, and toe-in affect?
Sounds like an old cold remedy. Not sure about castor but I take it like the other two it's all about getting your tyres in line with each other and the road surface.
So what exactly is castor? Apart from a bag of sugar or some oil :clown:
