What is injection pressure range for modern gasoline direct injection & common rail diesel injection systems?

0

Due to high compression ratio of a diesel engine the injection pressure is 3,000 pounds per square inch, or since 1 PSI is about 6.9 Kilo Pascals, the injection pressure will be around 20,700 KPa. Gasoline direct injection would not need to be as high due to the lower compression ratio and the fact that a gasoline engine is spark ignited.
