SCR means Silicon Controlled Rectifier. This device belongs to the family THYRISTORS. Thyristors denotes a family of semiconductor devices used for power control in DC and AC system. At present , the use of SCR is well spread and so vast that the word thyristor becomes synonymous with SCR. In construction, it is a pnpn device .
Dynamic Compression Ratio (DCR) is an important concept in high performance engines. Determining what the compression ratio is after the intake valve closes provides valuable information about how the engine will perform with a particular cam and octane. Definition: The Compression Ratio (CR) of an engine is the ratio of the cylinder volume compared to the combustion chamber volume. A cylinder with 10 units of volume (called the sweep volume) and a chamber with a volume of 1 has a 10:1 compression ratio. Static Compression Ratio (SCR) is the ratio most commonly referred to. It is derived from the sweep volume of the cylinder using the full crank stroke (BDC to TDC).
