It used four plunger pumps to deliver a pressure up to 3,000 pounds per square inch (210bar; 21MPa) every 90 of rotation to keep the fuel pressure adequately constant in the rail. Common rails are the holy orgasm of Diesel injection technology and the technology will soon be available on every Diesel . The main difference between a direct and a standard injection is the delivery of fuel and the way how this one mixes with incoming air. There is nothing like a diesel engine compared to other combustion engines. Everything from the CP3 to the injectors themselves, Wade lets you know in this video what each part does for your common rail system. The system was developed by the German specialists of the company "Bosch". These technologies have a similar design since they consist of a fuel rail that supplies fuel to injectors. Because of this, it is called as common rail injection system. For other uses, see, (multistroke injection) See BMW 2009 Brochure for 3 series, Hydraulically actuated electronic unit injection, "Nordhuser an Entwicklung des weltweit ersten Common-Rail-Diesels beteiligt IFA-Museum ffnet zur Nordhuser Museumsnacht", "240 Landmarks of Japanese Automotive Technology - Common rail ECD-U2", "Denso targets French, US automakers: World's No. For the typical distributor/inline system, the start of injection occurs at a predetermined pressure (often referred to as pop pressure) and ends at a predetermined pressure. The amount of the fuel injected in the cylinder is depends on the duration, size and number of holes in the nozzle tip and the fuel pressure and air pressure in the cylinders. The modern version of the common rail injection system that is used in diesel engines was invented in 1990. Newer Ford Powerstroke and Cummins injector systems use common rails. Thus, it increases power output and meets stringent emission norms. The header pressure must be that for which the injector system was designed because the injector system is differ in dimensions as the dimensions of the engine changes. The main suppliers of modern common rail systems are BOSCH, Delphi, Denso, and Siemens VDO (now owned by Continental AG).[8]. CarBikeTech Team regularly publishes specific technical articles on automotive technology. The pressure in the rail, as well as the start and end of the signal that activates the injector for each cylinder are electronically controlled. Turbocharging: Key technology for high-performance engines. It's performed using a high-voltage electric current, combined with a fine electrode, and is well-known for its . It really does help us out! Each injector is opened individually and electronically. And it maintains optimum residual fuel pressure.

In this episode, we are going to talk about 4 causes of common rail . It must enable to penetrate and diapers the fuel in the combustion chamber, combustion chamber is the place in the engine where the fuel catches the fire and produces high amount of energy which leads the vehicle forward. Diesel engines have historically used various forms of fuel injection. It, then, supplies the pressurised fuel via a high-pressure pipe to the inlet of the fuel-rail. To ensure fuel economy and clean burning. Thus, the system can reduce engine vibration. The high-pressure fuel supply pump is only responsible for supplying high-pressure fuel to this accumulator, and is not responsible for controlling fuel quantitative and injection timing. While not as influential as the invention of the diesel engine that it operates on, the common rail injection system has done a lot for diesel automobiles. Characteristic. A high pressure pump is utilized for providing fuel to the header, from where the fuel is estimated by the injector. This simplifies the purpose of the high-pressure pump in that it only needs to maintain a target pressure (either mechanically or electronically controlled). Camshaft-operated mechanical timing valves were used to supply the spring-loaded Brice/CAV/Lucas injectors, which injected through the side of the cylinder into the chamber formed between the pistons. Givesthe better fuel economy and clean burning. Furthermore, a Common Rail system uses a fuel rail. The automotive manufacturers refer to their common rail engines by their own brand names: Solenoid or piezoelectric valves 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 atomisation.

Common rail is a fuel injection system found in modern diesel engines. In this system the liquid fuel is injected directly into the combustion chamber without the aid of compressed air. Fuel combustion inside the engine is improved so that, if at all possible, emissions are not produced in the first place. Maximum of 2600 bar pressure rating Common Rail Fuel Injectors Cummins offers fuel injectors ranging in capability from 1600 to 2600 bar. [1] Doxford Engines used a common rail system in their opposed-piston marine engines from 1921 to 1980, where a multicylinder reciprocating fuel pump generated a pressure around 600 bars (60MPa; 8,700psi), with the fuel being stored in accumulator bottles. Some advanced common rail fuel systems perform as many as five injections per stroke. The common rail is a long metal cylinder. The main parameter characteristics of the stand is the power of the motor. Uniform spray pattern to ensure rapid mixing of fuel and air. As technology changes new challenges arise. A common-rail fuel injection system works differently than conventional injectors. What is the main function of the high-pressure rail on a common rail diesel engine? One other thing that common rail allows is that the injector can/will fire twice during combustion. The increase in the fuel pressure is a result of the latest engines' design. High-pressure injection delivers power and fuel consumption benefits over earlier lower pressure fuel injection,[citation needed] by injecting fuel as a larger number of smaller droplets, giving a much higher ratio of surface area to volume. The injection system has to perform the important role of initiating and controlling the whole combustion process. Common rail technology is a digitally controlled, high-pressure fuel injection and sensor system that optimizes engine efficiency & performance.
