Definitions

• the amount of fuel injected concentrates until the controlled ignition in the center of the combustion chamber, while in the Edge zones of almost pure combustion air is distributed without fuel components. So there can be no knocking and no knocking. There can also be no uncontrolled pre-combustion. Even in the presence of hot combustion chamber areas, the combustion in the method according to the invention is triggered by the ignition or injection timing and not by a hot "ignition source", as can be done during an injection during the intake stroke.
• the internal combustion engine 10 is operated as follows:
• an intake phase in which the piston 18 moves away from the high-pressure injection valve 22 and from the spark plug 26, air flows through the intake pipe 14 and an intake valve (not shown) into the combustion chamber 12 formed between the piston 18 and the cylinder head 39.
• the servomotor 32 is regulated by the control and regulating device 36 such that the throttle valve 30 is essentially parallel to the longitudinal extent of the intake pipe 14 is aligned.
• the exact position of the throttle valve 30 is transmitted to the control and regulating device 36 via the position transmitter 34.
• Position transmitter 34, control and regulating device 36 and servomotor 32 form a closed control loop. Because the throttle valve 30 is fully open during the intake phase, there are no throttle losses. This in turn means that the combustion chamber 12 can fill with air in an optimal manner.
• the control and regulating device 36 controls the high-pressure injection valve 22 at an angle of the crankshaft 20 of approximately ⁇ 61 ° before the top dead center ignition (ZOT) so that it opens. At an angle of the crankshaft 20 of ⁇ 34 ° ZOT, the high-pressure injection valve 22 is closed again by the control and regulating device 36. According to the low
