What are the pros and cons of the car’s opposition engine?

German Porsche and Japanese Subaru cars are traditionally equipped with opposed engines, which provide the car with excellent dynamic characteristics. For many motorists such a motor is a curiosity, and yet let’s try to figure out what the advantages and disadvantages of such a design, how to properly service and repair it and scrap car removal brampton.

Features of design
In fact, the opposition engines are an upgrade of the standard inline power unit. Engineers modified such a motor and designed a V-shaped design, but such units had a lot of disadvantages, including problems with mass balance and significant vibrations. Subsequently, to level out such petty jitters and lack of balance, opposition engines were created, in which the cylinders in the blocks have the opposite arrangement.

Initially, such power units began to be used serially in the sixties and seventies on Porsche brand cars. These are sports cars, which were distinguished by the compact size of the engines, while providing excellent power and excellent dynamics. Subsequently, the same technology was used by the Japanese manufacturer Subaru, which today is famous for its powerful sedans and wagons, always equipped with opposed engines.

Today, such opposed engines are high-tech units, which are fully controlled by electronics, can have four or six cylinders. These powertrains provide excellent vehicle dynamics, while also saving space under the hood while solving the problem of heavy vibration at high revs.

Advantages and disadvantages
Like any other technology, opposed engines have their certain advantages and disadvantages. It must be said that such engines are extremely critical to the quality of service performed. It is necessary to change the oil frequently, properly maintain the engine, using only spare parts and technical fluids recommended by the automaker.

The main advantage of such an engine is practically complete absence of vibration, as the cylinders moving in opposite directions level out the kinetic energy of each other. This allows not only to make driving the car more comfortable, but also eliminates the need to install various additional balancing shafts and other elements, which are mandatory on standard V-engines.

The oppositional engine technology used today makes it possible to get the maximum possible power from a small engine in terms of volume. Not surprisingly, such technology was used by Porsche and Subaru motorists, whose cars are traditionally considered to be sporty and dynamic. Even with a four-cylinder two-liter motor without using a turbocharger you can get 200-250 horsepower.

If we talk about the disadvantages of these motors, first of all they are noted the complexity of maintenance and mediocre reliability. For example, Subaru opposed engines often twist inserts, and subsequent repair of such engines cost tens and hundreds of thousands of rubles. Owners of cars of this Japanese brand are well familiar with such a problem, which is simply not possible to solve.

Another significant disadvantage of opposed engines is their complexity of maintenance and repair. Even on modern cars certain service works, for example replacement of spark plugs or oil can be performed by the car owner himself, but with opposites engines any simplest work resulted in the necessity to visit the service. Needless to say, the car owners had no choice but to pay for such work, as it was impossible to perform it themselves, and the masters at service stations asked for insane money for a simple oil change procedure.

It is extremely difficult to find good technicians, who would be familiar with the peculiarities of the opposition engines and undertake their maintenance and repair. The service stations often simply don’t want to deal with such cars, explaining it by their constructive complexity and lack of practical skills in repairing such cars. As a result, even the simplest breakdowns turned into a headache for car owners who did not know how to repair the machine.

Let’s summarize.
Opposite engines – this is quite an interesting development, which appeared in the middle of the last century. Today, such motors of the series are installed on Porsche and Subaru cars. Choosing such a car, you need to remember both the advantages of opposites engines, as well as their disadvantages. In particular, such engines are not reliable, especially on Subaru cars, and their maintenance and qualified repair presents certain difficulties.
