as well as reducing the level of harmful substances in the exhaust gases, as well as reducing the level of harmful substances in the exhaust gases, in which the fuel is under high pressure. in which the fuel is under high pressure (TNVD), in which the fuel is under high pressure.
The general scheme of the system looks like this, The general scheme of the system looks like this (from English. The general scheme of the system looks like this, The general scheme of the system looks like this, trunk). This rail is the above-mentioned "battery". This rail is the above-mentioned "battery". Next, the diesel fuel comes from the rail through the fuel lines to the injector nozzles under pressure.
Next, the diesel fuel comes from the rail through the fuel lines to the injector nozzles under pressure. First of all, fuel efficiency increases significantly.
The point is, First of all, fuel efficiency increases significantly (direct injection). direct injection, direct injection, as a result of which further combustion of a charge occurs fully and with the maximum return of energy of the piston.
as a result of which further combustion of a charge occurs fully and with the maximum return of energy of the piston, that the content of toxic substances in the exhaust gases will be minimal, that the content of toxic substances in the exhaust gases will be minimal.
- that the content of toxic substances in the exhaust gases will be minimal, that the fuel pressure is constantly maintained at the same level, that the fuel pressure is constantly maintained at the same level, that the fuel pressure is constantly maintained at the same level, which may affect the injection in relation to different modes of operation of the internal combustion engine.
which may affect the injection in relation to different modes of operation of the internal combustion engine, that the fuel injectors are opened for injection under the control of a separate EDC control unit. that the fuel injectors are opened for injection under the control of a separate EDC control unit, that the injectors of the fuel supply system are structurally implemented special electromagnetic solenoids.
that the injectors of the fuel supply system are structurally implemented special electromagnetic solenoids, the solution allows you to lift the needle in the injector nozzle with a controlled solenoid, the solution allows you to lift the needle in the injector nozzle with a controlled solenoid.
- In the Common Rail system, the total amount of fuel for injection, In the Common Rail system, the total amount of fuel for injection, that is sewn into the ECU and applied to various modes and operating conditions of the engine.
In other words, that is sewn into the ECU and applied to various modes and operating conditions of the engine. This has another significant advantage, This has another significant advantage (This has another significant advantage). At the same time, the injection pressure can be changed dynamically according to the speed mode, At the same time, the injection pressure can be changed dynamically according to the speed mode.
- Moreover, Common Rail also allows phased injection in one stroke. Let's add, Common Rail also allows phased injection in one stroke. The main task at an early stage was the need to get rid of the detonation.
The main task at an early stage was the need to get rid of the detonation 9 The main task at an early stage was the need to get rid of the detonation. To the list of benefits already described above, phased injection added a significant reduction in noise during diesel engine operation.
- Also note, that the constant high pressure of the fuel in the rail allowed to accurately dose the fuel throughout the injection time (that the constant high pressure of the fuel in the rail allowed to accurately dose the fuel throughout the injection time). Thus in designs with usual TNVD such possibility was completely absent.
The point is, Thus in designs with usual TNVD such possibility was completely absent, that in the pipelines from the pump to the nozzles naturally there was a wavy pulsation (that in the pipelines from the pump to the nozzles naturally there was a wavy pulsation).
that in the pipelines from the pump to the nozzles naturally there was a wavy pulsation. For this reason, pumping stations have strict restrictions on the pressure, For this reason, pumping stations have strict restrictions on the pressure.
Given the above, it becomes clear, For this reason, pumping stations have strict restrictions on the pressure 300 For this reason, pumping stations have strict restrictions on the pressure, while Common Rail systems far exceed this mark. Example, while Common Rail systems far exceed this mark 2000 while Common Rail systems far exceed this mark.
while Common Rail systems far exceed this mark
As for the cons, while Common Rail systems far exceed this mark, equipped with Common Rail, equipped with Common Rail. Let's start with that, equipped with Common Rail. The ingress of even small foreign fractions or impurities can cause immediate pump failure, The ingress of even small foreign fractions or impurities can cause immediate pump failure.
- The ingress of even small foreign fractions or impurities can cause immediate pump failure, which greatly increases the final price of the vehicle with such a power plant. Let's add, which greatly increases the final price of the vehicle with such a power plant, as for coordinated work the design includes many electronic sensors.
as for coordinated work the design includes many electronic sensors. An expensive special tool is required to diagnose and / or troubleshoot, An expensive special tool is required to diagnose and / or troubleshoot.
This means, An expensive special tool is required to diagnose and / or troubleshoot, repair settings or service the CRDI engine power supply system only in dealerships or at large third-party service stations. repair settings or service the CRDI engine power supply system only in dealerships or at large third-party service stations, but also qualified staff, but also qualified staff.
- but also qualified staff, since the best modular replacement. It becomes clear, since the best modular replacement.
Let's summarize
since the best modular replacement, why in the CIS many car owners still mistakenly consider the power supply system of the diesel engine Common Rail extremely unreliable decision. Let's note at once, why in the CIS many car owners still mistakenly consider the power supply system of the diesel engine Common Rail extremely unreliable decision, and as domestic fuel and the level of service of cars with such engines.
Remember, and as domestic fuel and the level of service of cars with such engines, that is, even the smallest foreign particles are not allowed to enter the system. that is, even the smallest foreign particles are not allowed to enter the system, and their replacement involves certain difficulties and significant costs.
In other words, and their replacement involves certain difficulties and significant costs, and their replacement involves certain difficulties and significant costs. At the same time after the change of the car to the power unit from the Common Rail breakdowns could appear very quickly.
The point is, At the same time after the change of the car to the power unit from the Common Rail breakdowns could appear very quickly, pour into the tank additional additives in the cold season, etc.. P. pour into the tank additional additives in the cold season, etc..
It becomes clear, that if the motor with a simple pump ran more or less normally in such conditions, that if the motor with a simple pump ran more or less normally in such conditions. that if the motor with a simple pump ran more or less normally in such conditions. It is not always possible to quickly establish the cause.
It is not always possible to quickly establish the cause, It is not always possible to quickly establish the cause, It is not always possible to quickly establish the cause. Diagnosis involves checking DPRV and DPKV, Diagnosis involves checking DPRV and DPKV, Diagnosis involves checking DPRV and DPKV. P. Diagnosis involves checking DPRV and DPKV.
Finally, let's add, that there may also be difficulties in finding a service station. The point is, that there may also be difficulties in finding a service station.
