Thermal 4Rendimiento: will be greater cuandot higher the T first hit in the combustion and lower the heat loss, the amount of heat gained is a function of the mass of fuel consumed per unit of time and heating power of este.El thermal performance can be defined as the ratio between the effective power and thermal power fuel CALRE losses through the exhaust gases account for 35% n otto engines and 30% in diesel, a refrigerating discover our exclusive special aproximadamnt evacuates the 30% of the heat engine in both types of 100% of the heat energy fuel ke eel pose the thermal combustion engines are capzace SoLaMnT transform between 35 and 50%. Mechanical Performance: it is expressed as the ratio between k ke is the effective power nl botiene motor shaft and the power indicated nl k diagram is obtained which expresses the work l tork obtained within the cylinder internal YNL involved ke no mechanical losses, losses of mechanical character k is counted in determining the mechanical performance are: "the energy used to transmit the movieminto the piston to the axis of slaida, principalmnt in friction between the segment and the cylinder and friction bearings and parts cigüeñal.-ke consumes energy as dispositivosauxiliares distribution system as the water pump and pumping work ke is used in insert and remove nl gas cylinder, set of mechanical losses comprise between 10 and 15%. Yield Cash: l balance between total losses and 100% of energy consumed from nl ocmbustible give rise to actual engine erformance. Otto engine heat losses: 60 65% mechanical losses: 10 15%. Total loss: 70 75%. Yield Cash: 25 30%. Diesel, heat losses: 50 60%. mechanical losses: 10 15%. Total loss: 60 70%. Yield Cash: 30 40%.Volumetric efficiency: defined as the degree of effectiveness achieved with the ke fill the cylinder is expressed as the ratio between the mass of ke gas enters the cylinder in one cycle and the more theoretical ke nl volume of the cylinder can be 4Rendimiento .. Engine: the energy contained in the combustion Kimicar home is transformed into heat by combustion of consguiente thus increasing pressure moves the piston thus obtaining asienergia mechanics, not all the fuel energy into useful work traforma, much is lost as energy aprovexable ke ke ke is obtained is less than the heat inicial.Perdidas: produced by the system refirgeracion and radiation heat loss to the important exterior.Es k heat is evacuated through the gas Mechanical escape.Perdidas: due to friction of moving Piezzo and the operation of auxiliary devices such as pump Kimicar etc.Perdidas aua: being cut motivated by a combustion

Torque: is a function of the applied force on the connecting rod and crankshaft elbow length being equal to the MIAD this race. Power: is defined as the amount of work done in a unit time. K factors determined or motor power: cilindrada.-filling ratio of cilindros.-Compressive-engine speeds. 5Motores policilindricos: pekeñas displacements to below are used 800cm3 engine cylinders 2 and 3 widely used in motorcycles and cylinder ke exceed the 4 litrosse engines built in 8 and 10 diesel cilindros.Los large cylinders using slow beam lengths with unit volume up to 2 liters, is made from 6 8 10 12 cylinders, due to the great force of the explosion was very crank rekiero robustos.En engines for tourism tends to relativamnt pekeñas cylinder displacement of 250 to 500cm3 which implies certain advantages in their comportmaientos.Disposition of cylinders: the outer dimensions d mootrs compartment must conform to occupy nl ke vehicles and engines of more than 6 cylinders in line are too long and high and esan subjected to excessive crankshaft torsional vibrations, are classified by dispocicion of their cylinder engine cylinder opposed horizontal line at v (boxer). V-cylinder engines: a bloke constiuido formed in V whose angle is usually 90 or 60 º tb s eencuentan V engine estrexa to 15 º. These lead engine size shorter and more anxos Lowest aunke applies to 6 or more engines in cilindros.Bloke W: used in engines from 8 to 12 cylinders, are compact and are classified as V-engines, it reduces the length of loke and cigueñal.Boxer: are arranged in 2 blokes horizontalmnt united at their base with a common crankshaft is a bloke in V at 180 ° the height of this engine keda very small, are built from 2 to 6 cylinders.Number of cylinders and firing order: the order of succession enendio certain pulse ke receives each piston, one begins with the contracting side engine flywheel with double inercia.En bloke starts you are located to the left cylinder after which listed by the Derex ke bloke are determined by the same side where the numbering starts
