Can 'Diesel' Really Be Part of Our Vocabulary?

"2007 – The Year Of The Diesel Hot Hatch"

Looking forward to a new year always requires a look back at the trends that developed last year. What was cutting edge in the automotive industry in the first 6 months of 2006 is bound to be main stream come August.

I guess we all new subconsciously that it would come, maybe we tried to convince ourselves that oil-burners could never give us that grin inducing performance.… Read More...

Camshafts durations and profiles.

"Cam(alot) of power!"

Cam profiles and cam durations.
The cam shaft controls the inlet and outlet ports. A pear shaped lobe on the shaft keeps the valve closed until the pointy bit rotates producing lift and opening the valve. Double overhead cams have separate profiles for inlet and outlet ports and are more tunable than single overhead cams.… Read More...

The best spark plugs & HT leads improve performance.

"Lets spark up about engines"

An efficient engine needs a good supply of cold air laden with oxygen.

The correct mixture of fuel and a good spark to ignite the mixture.

The two main components of a plug are:-
1)The ceramic casing which is a good insulator and
2)The electrodes from the central tip and the negative pick up contact which is connected to the engine block.

Lets look at the job of the coil in the spark system and see what it does.

Just as a power transformer converts mains 240 volts into a usable 9 volts for your charger or appliance a coil will increase the voltage.

A car battery/alternator will produce a paltry 12volts, certainly not enough to jump an air gap and create a spark.

An ignition coil raises the voltage in some installations between 20 and up to 40,000 volts and this allows the creation of a spark which can jump the air gap between the plugs. Read More...
