• Central piston pump connected to the fuel injection nozzle by a fuel line
• Administrating quantities using a solenoid valve (for individual cylinders)
• Crankshaft drive (synchronous angle to engine) by chain or toothed belt
• Direct needle activation
Because of the higher possible injection pressure and the direct control of the injector needle, the distributor pump injection system and pump nozzle are of particular benefit during opening and closing. High specific performance is therefore possible with high emission quality. The advantage of high specific performance makes high absolute performance values possible with four-cylinder engines with small cubic capacities.
