Do You Know About Otto Cycle As A Prospective Mercedes Benz Sprinter 515 Cdi For Sale Buyer


As a buyer of Mercedes Benz sprinter 515 CDI for sale, do you know, an internal combustion engine is a sort of transformer, which starts from the energy contained in gasoline and air to make it become mechanical energy. This transformation takes place through a combustion process, which represents the basic idea of the internal combustion engine. To explain it we will take for example the Otto Cycle of petrol engines, the simplest and most common on the planet.

Otto Cycle

The Otto cycle (the most popular four-stroke cycle) is so-called because of the name of its inventor, the   European engineer, Nikolaus Otto, who filed its patent. But he had not been the first to study the internal combustion engine, whose invention is to be attributed to the Italians Eugenio Barsanti, a physics teacher and Felice, a water engineer. The Italians' experimental engines were single-cylinder with vertical piston, but they did not include compression which was instead Otto's winning intuition. Its patent provided for the spark to strike at the moment of maximum compression of the gas mixture. The ‘four-stroke’ design, on the other hand, derives from the characteristic phases of combustion which are, precisely about: intake, compression, expansion, and exhaust. They are carried out in four strokes of the piston, that is, two complete turns of the crankshaft. 

Piston Stroke

The stroke of the piston means its movement from one extreme point to another, that is, where the piston stops for an instant to reverse its movement and are called ‘dead spots’, at lower and upper. The top dead center (tdc) is the one where the piston is closest to the cylinder head, while when it is at the minimum distance from the crankcase has reached the bottom dead center (bdc). The diameter of the piston, which is only a few hundredths of a millimeter less than that of the cylinder, is called a bore. Together with the stroke, which is the space covered by the piston between the tdc and the PMS bdc, it forms the so-called ‘characteristic measurements’ of an engine. The displacement, however, is the volume that generates the piston inside the cylinder when it is at the tdc. 

Reverse Action

As a prospective payer of Mercedes Benz sprinter 515 CDI price, a buyer pays attention to increase awareness about car and auto sector, the first phase of the Otto cycle (intake) requires that the air-fuel mixture is sucked into the cylinder. The suction valve opens and, at the same time, the piston goes down from the bdc to the tdc. In this phase, the piston acts as a suction pump, but as soon as it arrives at the tdc, it reverses its motion, begins to rise towards the bdc and simultaneously closes the suction valve. As the piston rises, it compresses the air-petrol mixture (compression), raises the internal pressure and increases efficiency. The compression ratio is very important, which is the ratio between maximum volume (piston to tdc) and minimum volume (piston to bdc) available to the gases inside the cylinder.
