valve and timing
Recently, with the addition of variable valve timing and knock sensors to delay ignition timing, it is possible to manufacture gasoline engines with compression ratios of over 11: 1 that can use 87 ( MON + RON )/ 2 ( octane rating ) fuel.
This figure, however, will also depend on cam ( i. e. valve ) timing.
Intake tuning, cylinder head design, valve timing and exhaust tuning determine how effectively an engine scavenges.

The next generation of common rail diesels is expected to use variable injection geometry, which allows the amount of fuel injected to be varied over a wider range, and variable valve timing ( see Mitsubishi's 4N13 diesel engine ) similar to that on petrol engines.
Changes to the 968's powertrain also included the addition of Porsche's then-new VarioCam variable valve timing system, newly optimized induction and exhaust systems, a dual-mass flywheel, and updated engine management electronics among other more minor revisions.
Early models featured a pioneering form of variable valve timing in an attempt to give greater control, but this caused the valves to burn and therefore it was abandoned.
Many technologies that have featured in production cars are not allowed, for example: variable valve timing, variable intake geometry, ABS brakes and traction control.
The advantage of a rotary valve is it enables the two-stroke engine's intake timing to be asymmetrical, which is not possible with piston port type engines.
The piston port type engine's intake timing opens and closes before and after top dead center at the same crank angle, making it symmetrical, whereas the rotary valve allows the opening to begin earlier and close earlier.
The fuel injection and valve timing is mechanically readjusted by using a different set of cams on the camshaft.
Reed-valve engines will run backwards just as well as piston-controlled porting, though rotary valve engines have asymmetrical inlet timing and will not run very well.

This helps scavenging when exhaust / inlet timing overlap is used and a wide speed range required, whereas poor poppet valve exhaust scavenging can dilute the fresh air / fuel mixture intake to a greater degree, being more speed dependent ( relying principally on exhaust / inlet system resonant tuning to separate the two streams ).
* An inherent disadvantage is that the piston in its course partially obscures the ports, thus making it difficult for gases to flow during the crucial overlap between the intake and exhaust valve timing usual in modern engines.
A poppet valve ( also called mushroom valve ) is a valve typically used to control the timing and quantity of gas or vapour flow into an engine.
