Motors are an essential part of any type of machine and of some important appliances that may be used daily, such as washing machine, dishwasher, blender and even personal computers or laptops. An engine is a machine especially designed for converting one form of energy into mechanical energy.
First machines that used simple motors are prehistoric. Then, in the Antiquity, the more complex engines appeared – they used human, water, wind or animal power. The Industrial Revolution had meant a huge step on the ladder of progress – it was then that the mankind started to create more complex machines and to work for their development. What added most to the interest in powerful and light engines was the first successfully sold automobile. At the beginning, the most successful for light automobiles was the lightweight petrol engine, while the Diesel ones were used for trucks and buses. Along with the development of technology, turbo Diesel engines have become very popular, even for small cars.
In recent years, diesel engines have outworked gasoline ones, due to their benefits – they produce lower hydrocarbon, emit smaller amounts of carbon dioxide and are also more fuel efficient. There has been an increase in the engine capacity, in its size, in its pressure and in the rate at which the engines produce work – everything just for improving the motors’ efficiency.
A great part of the motors nowadays need oil for a better work or for not suffering any damage. The most common example is that of cars – they use different types of engines oil, like conventional, synthetic or high-mileage motor oil. Yet, there are some differences between synthetic and conventional motor oil that should be known. Considering what type of engine, you have and what expectations you have from your car, these differences are essentials for the safety of your car. You can either keep it in a good condition or deteriorate it. It depends entirely on the attention you pay to the car manual when you first buy it, because replacing synthetic oil with conventional one may lead to huge damage brought to your car motor.
The greater difference between them may be notified right from their names – one is made from laboratory obtained ingredients and the other is extracted from natural ingredients. As the users say, the synthetic oil is far better than the conventional one, because it is enhanced with the best additive package in order to make it better for motors. Using synthetic oil may be an excellent treatment for your car’s engine, because it keeps it both clean and in a good condition. If you have a clean motor, your car will not be damaged. A drawback of conventional oil is that it can sometimes form different kinds of impurities, which will drastically reduce the engine’s life. Moreover, between these two types of oil, the synthetic one works better on lower temperatures and on longer periods of time. If your motor reaches a high temperature when it’s working on short periods of time, only imagine how hot it must be when you drive for hours in a rot. Therefore, it is better to use synthetic oil, because it takes greater car of your engine and keeps it in a good condition.
In most petrol engines, the air and fuel are usually pre-mixed in a carburetor before compression, whereas in a Diesel one, only the air is compressed. Because of the differences between the two different fuels in burn rates, petrol motors are designed with different timing than Diesels. It is said that petrol engines run at a higher speed than diesels, due to not only their lighter pistons, but also to a more quickly burning of petrol than of diesel. However, petrol engines have lower efficiency in comparison to diesel ones, because they have a lower compression ratio.
Of course, any type of motors brings serious damage to the environment. Whether it runs with conventional or synthetic oil make no difference to the negative impact it has especially on the air quality. Recently, there has been a growing emphasis on the pollution that is produced by automobile, airplanes or trains. It has been proposed that alternative power sources should be found, because Diesel engines have gained great popularity among the automobile owners. The more cars are used; the poorer life’s quality is. While driving, there’s a huge waste of carbon monoxide, which is highly toxic. Also, there are greenhouse gas emissions from the widespread use of engines in the modern world, which contribute to the global greenhouse effect.
Nowadays, most cars are propelled by an internal combustion engine running on diesel or gasoline. Both of them contribute to climate change and global warming and are blamed for causing air pollution. There have been improvements regarding the replacement of existing fuels with alternative energy sources, such as natural gas vehicles or ethanol flexible-fuel cars.
Apart from car motors, there are also other fuel-burning devices invented, such as heaters or boilers, which are designed to burn multiple types of fuels in its operation and are called multi-fuels. It’s most common application is in military setting, where the normally-used turbine might not resist.
To sum up, motors are one of the most important parts of any kind of machine. Although they have propelled the mankind to a higher level – that of continually improvement – they have a very negative impact on the environment; they affect not only the surroundings, the air, or the animals, but also the people living on this planet.
