Electronic Unit Injector Vs Common Rail

Common Rail injectors make possible fine electronic control over the fuel injection time and quantity and the higher pressure that the common rail technology makes available provides better fuel atomization. Common Rail Electronic Unit InjectorUnit Pump Fuel Systems DIPACO Parts Catalog For.

Common Rail Injection System Pressure Control In 2021 Common Rail Pressure Control Valve Electronic Control Unit

With this system a small amount of fuel is injected into the cylinder before the full injection to optimize timing and fuel quantity.

Electronic unit injector vs common rail. While advanced electronically controlled unit injector systems with the capability for multiple injections and rate shaping have been developed unit injectors are gradually replaced by common rail technology. Bosch Common Rail Injectors The Bosch Common Rail Injector injects the precise amount of fuel into the combustion chamber at the right time and in the right quantity. A fuel pump injection pump is fitted for each engine cylinder.

105 East Parr Blvd. This can be actuated with a solenoid on the injector and the duration and timing will be controlled by the ECU Electronic Control Unit. Common rail uses a high-pressure rail to deliver fuel to each solenoid valve.

At present we are able to satisfy all users different. In order to lower engine noise the engines electronic control unit can inject a small amount of diesel just before the main injection event pilot injection thus reducing its explosiveness and. By adding crystals to electric current piezo electronics are now added to the common rail system controlling two pilot sprays a main spray and two post sprays.

Piezo-electric common-rail injectors are also quieter than their predecessors while increasing horsepower and torque. This is opposed to the traditional direct fuel injection system of using low-pressure pump nozzles to deliver fuel while producing more emissions. If your vehicle is specified in the list of applicable models below all other 20 TDI models feature just one type of technology it is important.

The pump piston is fitted in the pump cylinder with such precision that high injection pressure is guaranteed even at low speeds. The injectors in a common rail system are for the most part electronic utilizing solenoids and relying on the ECM to control their timing. Proven for many years the unit pump system is an injection system consisting of an electronically controlled unit pump and nozzle holder assemblies with injection pressures of up to 1800 bar.

In this system the fuel is distributed to the injector from a high pressure accumulator and through a rail and this rail is common to all the cylinder because of this only it is called as common rail injection system. At one time the unit injector system had the capability to develop the highest injection pressure among all types of injection systems. If youre unfamiliar with common rail it is a term that defines the fuel injection system used for these engines.

The fuel injection law of the common rail system is rectangular with high explosion pressure and rough combustion which is not conducive to reducing NOX. RaceChip chip tuning is specially customized to the applicable fuel injection technology with respect to both hardware and software. The quantity of the fuel and atomization are controlled electronically using a programmable control module.

Several Audi Seat Skoda and VW model series with 20 TDI engines use both CR and PD Pumpe-Düse Unit injector technology. The injection law of the electronic unit pump is the same as that of the mechanical in-line pump which is beneficial for reducing NOX. It receives the fuel from the pump and distributes it to.
