Ryan Rotary Performance are now able to offer you a full compression testing facility with a printout direct from the compression tester. The price of this service is £80
Why do I need a Compression Test?
All combustion engines require three elements to function correctly:
The basic 4 stroke phase of a combustion engine also known as the “otto cycle” and can be described by the following: Suck – Squeeze – Bang – Blow.
This works in the following way:
The engine Sucks in the required amount of fuel and air, squeezes or “compresses” this into a smaller combustion chamber, ignites the fuel/air mixture which is where we get our bang, the gasses propel the rotor round and the exhaust gasses are blown through the exhaust pipe.
One of the main issues with a rotary Wankel engine is during this process the Apex seals which seal off the working chambers have to travel much further than their equivalent piston ring. This results in the seals in a rotary engine wearing faster than they would in a piston engine which can result in lower compression.
“The Mazda Wankel engines (a type of rotary combustion engine) comprise a family of car engines produced by Mazda, derived from experiments in the early 1960s by Felix Wankel, a German engineer. Over the years, displacement has been increased and turbocharging has been added”…… (read more)
A compression test therefore can give an indication to the health of an engine as well as being a useful diagnostic should you be having trouble with your rotary.
Our compression tester is mobile, so we can come to you if you require to carry this out at an additional charge. Contact us now to book your test in!
