Purpose of Diesel Engine Common Rail System

Purpose of Diesel Engine Common Rail System – The development of diesel engine injection system technology from a conventional model to an electronic injection system is called Common rail (Efi-Diesel). This new technology has a significant impact on engine performance. The existence of the Euro Emission Regulation demands that the output of exhaust emissions must be environmentally friendly. This regulation forces major changes in automotive technology, especially diesel engines. The biggest changes in the Diesel engine are in the arrangement of fuel supply, valve opening, and air control. Moreover, exhaust emission standards have now reached EURO 4 level. So that forces manufacturers to develop diesel engines with advanced technology that use a high-pressure fuel injection system that can improve the combustion process. Thus, it is able to produce exhaust gases to be environmentally friendly.

The complete combustion process requires as much compressed air as possible, high fuel pressure, and the right timing of fuel injection. Conventional diesel engines regulate this mechanically in the injection pump through a governor and an automatic timer and injector that injects fuel. In EFI-Diesel the technology has changed, namely by controlling the engine requirements through an electronic system. This control is through a very accurate fuel injection setting so that it ensures a more complete combustion process to produce optimum engine power. The diesel engine electronic system is capable of producing efficient fuel consumption and lower emissions when compared to conventional systems.

Purpose of Diesel Motor Common Rail System

The injection pressure setting, injection amount setting, and injection timing are controlled electronically. This electronic control uses the ECU (Electronic Control Unit). This control will produce more accurate machine work. High-pressure fuel ensures better fuel atomization. High-pressure fuel storage on the common rail ensures sufficient high-pressure fuel at all engine speed conditions.

By using the Common Rail System we will get;

  1. High Performance – With flexible and accurate injection timing, injection pressure setting according to engine load and speed as well as more accurate and electronic injection amount adjustment as needed, resulting in a more complete combustion process so that higher output and engine performance will increase more good.
  2. Economical Fuel – Electronic mechanism will control fuel injection. The result will be more accurate guaranteeing the amount of fuel according to needs so that fuel is more economical.
  3. Low Noise and Vibration – This latest technology is able to reduce vibration and sound from the engine.
  4. Low pollution – With better combustion results in lower exhaust emissions making it more environmentally friendly.

Common Rail Advantages and Disadvantages

The common rail injection engine is a modern version of the diesel engine. Most of the diesel-powered vehicles you see today have common rail technology. If you are unfamiliar with common rail, it is the term that defines the fuel injection system used for these engines.

Rails or rails or common rails use high-pressure rails to deliver fuel to each solenoid valve. This contrasts with traditional direct fuel injection systems which use low-pressure pump nozzles to deliver fuel while producing more emissions.

Top 5 Advantages of Common Rail Diesel Injection

The common rail injection engine allows for better control of emissions and fuel and power consumption. In other words, engines with common rail technology can deliver more power to the vehicle while consuming less fuel and producing fewer emissions.

Therefore, cars with this technology comply with government regulators who want to limit the volume of vehicle exhaust carbon emissions. Here are five advantages of common rail technology vs direct injection.

  1. Lower Emissions – One of the reasons the common rail injection engine was invented by vehicle manufacturers is because the government made stricter regulations on carbon emissions. Do you remember when a big diesel truck emitted a lot of black smoke into the air? You hardly see it anymore because engines with common rail technology are designed to reduce these emissions. This situation is better for the environment whether we want to believe in global warming or not.
  2. More Power – Research has shown that a vehicle with a common rail technology engine will produce 25% more power than a traditional diesel injection engine. This means that the overall performance of the engine will increase.
  3. Very Smooth – The diesel fuel injection system is known to be very noisy when the engine is running. Common rail technology will generally reduce a lot of noise you may remember hearing. This technology makes the driving experience more enjoyable for you and those around you on the road.
  4. Less Vibration – In the past, many people felt a strong vibration when driving a car with a diesel fuel injection engine. Now, common rail technology reduces a lot of these vibrations for a much more comfortable driving experience.
  5. Better Mileage – Since the common rail injection engine delivers more power, it means you’ll get better mileage in units of fuel. As a result, your fuel economy will also be better. This means less money will be spent on fuel when we travel.

Top 3 Disadvantages of Common Rail Injection

With all the advantages of the common rail engine, there are some disadvantages too. While there are fewer drawbacks, they can influence your decision whether to buy a common rail injection engine-powered vehicle or not.

  1. Higher Vehicle Costs – Vehicles with common rail injection engines will cost more than traditional direct injection engines.
  2. Expensive Parts – Since common rail diesel engines are more expensive, replacement parts will also be expensive. For novice vehicle owners, especially for business, you should not use the common rail injection car type.
  3. More Maintenance – Common rail injection engines require more maintenance than traditional diesel engines. Even if you do the maintenance yourself, it still takes more time, effort, and cost as we mentioned above with a higher cost of spare parts.

Therefore, by looking at the advantages and disadvantages of this injection engine, you can decide whether to choose a conventional injection diesel engine or one that uses common rail technology. Make your choice now.
