ENGINE TIMING

[Roy]

HI there

Having read the articles I can tell you that the most common method used
now in europe for engine timing is the flywheel sensor with a missing
tooth in conjunction with a cam sensor.  The flywheel sensor has in the
case of Fords 36 teeth with one missing.  The sensor is in line with
this missing tooth when the crank is at 90=B0 BTDC with 4 cylinders and
60=B0 with 6 cylinders.  The reason for this is that at 90=B0 BTDC OR ATD=
C
on a 4 cylinder engine the crank acceleration / deceleration is at a
minimum.  The cam sensor provides a signal to indicate the stroke.  When
the cam signal and crank missing pulse are detected this is number 1
cylinder on compression aproaching the point of ignition for number 1.

Bosch tend to use 60 tooth wheels with two teeth missing.

As far as oil pumps go,  I thought it was an EFI list!.

If you look at a so called high presure oil pump compared to the std
article you will find that it simply has a larger volume pumping
chamber  which means for a given number of turns it will pump a greater
volume of oil, it will not give more pressure since this is controlled
by the pressure relief valve.  What it can do is maintain this pressure
better since if you were to increase the clearance on all your crank
bearings there would still be enough oil flow to maintain the system
pressure wheras with the standard pump this may not be the case.

I hope this helps,
