A crucial concept in engine tuning is the relationship between compression pressure (which is affected by the throttle plate) and ignition timing. This is vital for maximizing power and efficiency while preventing engine knock. ​Compression Pressure vs. Throttle Plate ​The static compression ratio of an engine is a fixed, mechanical property determined by the volume of the cylinder at its largest point (piston at Bottom Dead Center or BDC) versus its smallest point (piston at Top Dead Center or

Variable Compression Ratio Engine Like & Follow me ➡️TchZoo Variable compression ratio is a technology to adjust the compression ratio of an internal combustion engine while the engine is in operation. This is done to increase fuel efficiency while under varying loads. Variable compression engines allow the volume above the piston at top dead centre to be changed. Higher loads require lower ratios to increase power, while lower loads need higher ratios to increase efficiency, to lower fuel consu
