Cylinder pattern

Automobile engine cylinder arrangement types mainly include inline, v-shaped, horizontal contraposition, W. Array ( L) Are all lined up for up and down reciprocating motion of the cylinder, cylinder engine under more commonly in this way. It is characterized by simple technology, low manufacturing cost, easy to repair, but in the operation of the engine vibration is larger. For more fuel-efficient cars. V is for all the cylinder is divided into two rows, the equivalent of two cylinder in the engine connected to a certain point of view, is the ideal form of engine. Is characterized by smooth operation, vibration and noise than the array ( L) The engine. And the size of the Angle between the two columns of cylinder of engine have a greater influence upon the comfort, ° is optimal, because the factory has other considerations to the engine, there will be °, °, such as a variety of forms, general Angle is smaller, the smaller the width of the engine, convenience in a small cabin in place, but at the same time than the corresponding increase. And Angle increase engine's center of gravity height is lower, is beneficial to body stability in the corner. V type engine structure is relatively complex, the manufacturing cost and maintenance cost is higher, more used in high-grade car. Horizontally opposed is in horizontal way to connect two columns of cylinder, horizontal reciprocating movement, all the pistons do characteristic is engine balance is better, and relatively low center of gravity, is conducive to the stability of the car. Because of all cylinder is placed, the upper part of lubrication is a difficult problem, relative to other forms of engine, requires more sophisticated lubrication system, virtually raised the manufacturing cost. W and Volkswagen's first, but it is not four exhaust cylinder arranged in W, but through the complicated space structure will be two small Angle V of the four columns of engine cylinder connected on the same crankshaft. This can reduce the volume of the engine, at the same time very quiet operation smoothly. But W type engine structural complexity of the other man suddenly tongue, high manufacturing costs so that it can only be used on some large luxury cars.
