As a Used Auto Buyer, Do You Know About Carburettor In Used Iveco Trucks For Sale In Europe
Do you know, what are the real differences between an engine fueled by a carburettor and one powered by indirect and direct electronic injection inside? So, Considered by insiders as trivially as a pump, the eight cycle engine must be powered in the right way in order to express all its power and limit polluting emissions . The fuel in used iveco trucks for sale in europe can be supplied through one or more carburetors or through indirect or direct electronic injection; depending on the implementation, the latter requires the use of one or more injectors per cylinder.
Well Defined Ratio
The carburettor is one of the fundamental parts of which the fuel circuit of an internal combustion engine with positive ignition is composed and takes care of preparing the mixture of air (comburent) and fuel (petrol) to be sent into the combustion chamber. This mixture must respect a well-defined stoichiometric ratio to allow the engine to express its characteristics. Subsequently the mixture thus composed is recalled by the depression created by the moving pistons, up to the combustion chamber. The quantity of gas (mixture) supplied to the engine is determined by a simple butterfly valve or by a gate valve inside the carburettor which, depending on its opening, can favor or hinder its passage. Usually the carburettor is placed between the air filter and the thermal unit which is composed of cylinders, cylinder head, piston and combustion chamber. The main difficulty of this feeding system is that of not being able to provide a correct stoichiometric ratio of the mixture as the load changes, particularly in situations of heavy use of the vehicle.
Indirect injection is a fuel system managed by software using sensors that constantly monitor the operation of the engine in real time. We can count two types of indirect injection: "single point" and "multi point". The first generally includes a single injector located in the intake manifold. The second type instead uses an injector per cylinder, located upstream of each of the intake valves. Whether it is a single or multi type, the injection is managed by a control unit, which reads the values coming from the lambda probe positioned on the exhaust manifold and a sensor delegated to detect the air flow in the intake manifold. Consequently the software regulates the dose of fuel to be injected , necessary for the correct operation of the engine in those particular conditions of use. Compared to a carburettor type fuel supply, indirect injection has an enormous advantage from the point of view of fuel consumption and pollutants emitted, without taking into account the best engine performance at different rotation and load regimes.
Next Level
Direct injection is also a fuel system managed directly by software or a control unit that controls all the operating parameters of the engine and is therefore able to react accordingly, optimizing the engine's operation and performance automatically and in a timely manner. The injectors in this case are positioned directly in the cylinder head and are powered by a high pressure pump. This technology involves the design and use of particular shapes of combustion chamber and pistons in order to optimize the functioning of the system. Basically we try to inject a lean mixture (more air than gasoline), but locally (near the candle) "stoichiometric" so that it ignites. Subsequently, the particular shape of the chamber and piston will direct the expanded gases from the spark plug towards the walls, creating thermal insulation of the combustion chamber, allowing the adoption of compression ratios. higher and reducing the phenomenon of detonation. Needless to say, direct injection has a big advantage in terms of power: the torque delivered, the elasticity and the behavior of the engine stands on another level compared to other fuel systems. The only disadvantage is most likely the complexity of the construction which involves the use of increasingly sophisticated control systems and materials.
Lower Losses
In general, however, we distinguish two basic types of injection namely direct and indirect injection . To understand the operation of the direct injection engine, it is necessary to make some brief references to the indirect injection engine. The indirect injection engine was equipped with injectors that did not spray the fuel directly into the combustion chamber but inside a pre-chamber in which the "glow plugs" heated the pre-chamber itself. The glow plugs, unlike the classic candles, are always lit generating an energy in the form of a constant spark over time. The diesel engine with direct injection was born in the twenties and rose to the top thanks to the Fiat company that used it in the production of the Fiat Croma TD ID. A used iveco trucks price in Europe payer need to know, in the direct injection engine the fuel is literally thrown into the combustion chamber directly without any passage in the anteroom. The injection pressure starts as per process; the efficiency of a direct injection engine it is given by the lower thermal losses since the gasoline remains in the cylinder and does not evaporate on the walls of the intake ducts and therefore there is an increase in the volumetric efficiency; the pressure in the combustion chamber and the more direct path that the exhaust gas makes to exit the cylinders. To be precise, The benefits of this type of power supply also ensures better performance and lower fuel consumption.
