Compression Ratio: The ratio of maximum engine based on an air-fuel value known as stoichiometric cylinder volume (when the piston is at the bottom or 14.7:1. In most fuel injection systems rich/lean of its stroke) to minimum engine cylinder volume is determined by voltage signal from the oxygen (with the piston at TDC). Thus, the theoretical sensor. An excess of oxygen lean is a voltage of amount that the air to fuel mixture is compressed less than .4 volts. A rich condition is indicated by i
