In order to understand the true comparison of the two engines, we also need to compare the engine's quality from the following parameters, please see the article from Cummins Engine Parts Editor:
扫雷红包群规则大全first look at one of the most common engine parameters-engine displacement. engine displacement is the sum of the working volume of each cylinder of the engine, and is generally expressed in liters (l). the cylinder working volume refers to the volume of gas swept by the piston from top dead center to bottom dead center, also known as single-cylinder displacement, which depends on the cylinder diameter and piston stroke. engine displacement is a very important engine parameter. it is more representative of the size of the engine than the cylinder bore and the number of cylinders. many indicators of the engine are closely related to the displacement. generally, the larger the displacement, the greater the engine output.
扫雷红包群规则大全number of cylinders:
扫雷红包群规则大全look at other common parameters of the engine. many junior riders reflect that they often see the words "l4", "v6", "v8", "w12" and so on in the engine column of the car information, trying to figure out what it means. these indicate the arrangement and number of cylinders of the engine. the number of cylinders commonly used in automobile engines is 3 cylinders, 4 cylinders, 6 cylinders, 8 cylinders, 10 cylinders, 12 cylinders and so on.
third, the cylinder arrangement:
扫雷红包群规则大全cylinder arrangement, as the name implies, refers to the arrangement of the individual cylinders of a multi-cylinder internal combustion engine. to put it bluntly, it is the queue formation of the cylinders on an engine.
current mainstream engine cylinder arrangement:
扫雷红包群规则大全(1) l: inline
(2) v: v-shaped arrangement
扫雷红包群规则大全(3) w: w-shaped arrangement
(4) h: horizontally opposed engine
(5) r: rotor engine
