Injection

Autotronics » Injection

Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of an injector. All diesel engines use fuel injection by design. Petrol engines can use gasoline direct injection, where the fuel is directly delivered into the combustion chamber, or indirect injection where the fuel is mixed with air before the intake stroke. The common rail direct fuel injection is a direct fuel injection system for diesel engines. The system is named after the shared high-pressure reservoir (common rail) that supplies all the cylinders with fuel. Modern common rail systems, whilst working on the same principle, are governed by an Engine Control Unit (ECU), which opens each injector electrically rather than mechanically. Common rail systems have a modular design and each system consists of a high-pressure pump (to compress the fuel and to supply it in the required quantity), injectors (consisting of nozzles), a rail and an ECU. For this category, De Lorenzo has designed simulators, demonstrators and advanced training systems. The simulators deal with aspects such as engine operation and electronic fuel injection, common rail direct injection for diesel engine, sensors and actuators in fuel injection system and injection control system. Troubleshooting’s and CAI software are provided in all of them. The demonstrators, that include real components, deal with aspects such as common rail diesel engine management system, Multipoint Petrol Injection (MPI) system MOTRONIC M 3.8.X based on Original Equipment Manufacturer (OEM) components of Audi/VW, direct petrol injection (FSI) system MOTRONIC MED 7.5.10 based also on OEM components of Audi/VW, multipoint petrol injection (MPI) system MOTRONIC based on fully operational engine installed in a mobile frame, common rail diesel injection system based on fully operational diesel engine model installed in a mobile frame and panel with real components of a VW car model with MOTRONIC fuel injection system. All the demonstrators are equipped with intelligent faults setting and troubleshooting. There are also advanced training systems such as gasoline engine and diesel engine test benches for the study of the four-stroke gasoline combustion engine and single-cylinder diesel combustion engine. Each of the latter two benches is equipped with a complete computer system to monitor and to record the characteristics of the curves. They are recommended for professional institutes, vocational schools and technical colleges.

COMMON RAIL DIRECT INJECTION FOR DIESEL ENGINE

LEARNING EXPERIENCE
This simulator allows the study, the testing and the troubleshooting on HDI (CDI - CR) injection systems for diesel engines
Similarly to what happens for the traditional injection petrol engines, where, the pressure of the fuel is only few bars, the HDI injection system uses a high pressure (up to 1500 bar) electric pump and a single manifold (common rail) to connect the pump to the electro-injectors. These are electronically and individually controlled for what concerns the start and the duration of the injection.
In the conventional diesel engine, the rotation speed of the engine controls the pressure to the injectors and, furthermore, pressure and injection are strictly correlated, because only when the pressure exceeds a given threshold there is the mechanical opening of the injector.
Therefore, the advantages of the common rail are rather evident:
• High pressure also at low regimes;
• Excellent atomization and dispersion of the fuel;
• Increase of the torque;
• Reduction of the noise;
• Reduction of the consumptions and of the emissions.
