4, electronic control system pump nozzle

The future of truck diesel engine combustion system requirements 1 50 MPa around the maximum injection pressure to meet emissions and noise regulations. For this reason the world's major car companies in the development of high-voltage-controlled fuel injection system, the most representative Is the electronic control system pump nozzle. This device can be divided into machine-driven and has a two-pressure, the jet can reach very high pressure, fuel atomization to improve the quality and greatly reduce the diesel engine combustion system of the cylinder swirl The request can even be used without the swirl combustion system.
