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 ?

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:
