engine is the most important configuration in the car and the most concerned configuration for all car owners. When buying a car, everyone will check the engine displacement, understand the engine's output power, and check whether the engine has oil leakage. Because the engine is the "heart" of the car, once a problem occurs, it will affect the mechanical performance of the whole vehicle.
But everyone talks about engines every day. Do you know what types of engines are? Are you using the horizontally opposed engine or the V engine in your car? Today I will take you to learn about the most famous engines in the world. You can see which engine your car belongs to. The first model of
is the inline engine
inline engine. Its cylinder block and crankshaft are very simple, and the manufacturing cost is relatively low. The engine has high stability and good characteristics under low torque. It can bring good output to the whole vehicle and reduce the fuel consumption of the vehicle. Family cars and SUV models are basically equipped with inline engines.
From the book meaning, you can also see that this kind of engine adopts a straight line arrangement. Generally, the letter "L" is represented, and the following numbers represent the number of cylinders of the engine. L3 represents the inline 3-cylinder engine, and L4 represents the inline 4-cylinder engine. Family cars such as Honda Civic , Volkswagen Lavida, Nissan Sylphy and Mazda Angkesella all use inline engines. Although the inline engine is low in cost and fuel economy is not bad, this arrangement requires relatively large space. If 8 cylinders are laid out, it will occupy most of the interior space. Moreover, this layout produces relatively low power and is only suitable for ordinary family cars. If it is a high-performance model with large displacement, you need to use a V-engine.
The second model, V-type engine,
V-type engine, solves the disadvantage of the inline engine of , , that cannot be laid out in multiple cylinders. It divides all cylinders into two groups, and arranges adjacent cylinders together at a certain angle, which looks like the English letter "V". This allows more cylinders to be laid out, the diameter of the cylinders can be expanded, and the performance of the engine can be improved.
VW Phaeton , and Rolls-Royce , all adopt this layout. It can reduce the space occupied by the engine, leave more space for the passenger compartment, and ensure the comfort of the space inside the car. Moreover, this layout can also offset the vibration between some cylinders and improve the mechanical performance of the vehicle.
However, the structure of this engine is more complex than that of an inline engine, and the manufacturing cost is higher. Once a failure occurs, the maintenance cost is more expensive. Therefore, this kind of engine is basically found in relatively expensive luxury cars, and V-shaped engines are basically not available in ordinary family cars.
The third model, rotor engine
Many people think that the rotor technology was developed by Mazda , but in fact it is not at all. The rotor engine was first invented by a German named Fiaz Wanker. Mazda just paid for the technology and applied it to its own cars.
However, in the early stage, because the rotor engine was not common, few people understood it, and basically no repair could be done if there was a fault, which led to many people questioning this technology. Fortunately, after so many years of research, Mazda has mastered rotor technology and made it its "living signboard". The fourth model of
, horizontal opposing engine,
, horizontal opposing engine, of course, the most widely used is the Subaru in Japanese cars. Other Japanese brands use inline engines, and only Subaru has always insisted on using horizontal opposing engines. Although this maverick style has greatly hindered Subaru's development path, those who know it know the advantages of this engine.
Unlike inline engines and V-type engines, the horizontally opposed engine distributes piston evenly on both sides of the crankshaft, so that it moves left and right in the horizontal direction.The advantage of horizontally opposed engines is that they can lower the center of gravity of the vehicle and make the car more stable while driving. The disadvantage is that the structure is too complex and it is difficult for the engine to get average lubrication.
Because the engine moves horizontally, due to the influence of gravity, the friction between the top and bottom of the engine and the cylinder liner will be uneven. Over time, problems such as uneven cylinder pressure will be caused, which will aggravate the shaking of the vehicle.
However, because the horizontal opposing engine has too great advantages in improving vehicle acceleration performance, many racing cars also use horizontal opposing engines on , such as Porsche 718, 911 and other world-class racing cars.
These four engines are currently the most widely used in the automotive field, among which inline engines are the most widely used in the household automobile field, and we often see them. Horizontal opposing engines and V-type engines are also mainly equipped on relatively expensive luxury cars or sports car . I wonder which engine is on your car?
