High-end combustion engine pre-start procedure

1 post in this topic

From an evo article on the new supercharged V8 that will be featured in the upcoming Jaguar Rs:

How advanced is this engine? One example. the use of gasoline Direct Injection (GDI) controls combustion in such a way as to effectively shape the way the cylinder pressure rises and falls as each cylinder fires. When you hit the start button the engine will synchronise, analyze the current air and coolant temperature, check all the sensors are working, set the fuel pressure on the twin double-acting high pressure pumps, check and adjust throttle angle, set all four cam positions, charge up the ignition coils and the 160volt injector control circuit and be ready to fire the first cylinder within one revolution of the engine.

In order to maximize control at higher rpm, the next incarnation of Bosch's Direct Fuel Injection for gasoline-fueled engines will run at something like 3000psi!
