In the history of automobile development, many classic engines have been born, such as Volkswagen’s classic EA888, Subaru boxer engine, and Mazda rotary engine. 1. Volkswagen’s classic EA888
The Volkswagen EA888 engine was developed to replace the EA113 engine at that time. The early EA888 was not only installed on high-end brands like Audi, but also on other Volkswagen models. It is a true classic engine of the Volkswagen Group.
The advantage of the first-generation EA888 engine was that it adopted a variety of advanced technologies at that time, such as in-cylinder direct injection, turbocharging and variable valve timing. However, due to the technical limitations and design at the time, Defects may also include oil burning, oil-gas separator failure, carbon deposits, timing chain tooth skipping, oil leakage, etc. However, after continuous development, the current EA888 has developed to the third generation, which has basically solved these shortcomings.
Due to its extensive assembly and heavy investment in technology, EA888 has long become the most classic engine of the Volkswagen Group. 2. Subaru Boxer Engine
Speaking of Subaru, one must mention its classic boxer engine. In terms of design, the horizontally opposed engine has its inherent advantages. In the horizontally opposed engine, the engine pistons are evenly distributed on both sides of the crankshaft and move left and right in the horizontal direction.
This unique design can reduce the overall height and length of the engine, lower the center of gravity of the vehicle, and drive the vehicle more smoothly. The engine is installed on the center line of the vehicle, and the torque generated by the two pistons is mutually exclusive. Offset, greatly reducing the vibration of the vehicle while driving, greatly increasing the engine speed and reducing noise. ?3. Mazda Rotary Engine
Mazda’s rotary engine technology was not actually invented by Mazda itself. Instead, it purchased the patent of the German Figas Wankel to solve the problem of cylinder pull of the rotary engine. It was successfully listed.
The advantage of the rotary engine is that the rotor does work three times per revolution. Compared with the ordinary four-stroke engine which does power once every two revolutions, it has greater horsepower but smaller volume. In addition, due to the axial motion characteristics of its rotary engine, it can achieve high speeds without precise crankshaft balancing.
