There are a number of advantages to naturally aspirated car engines. Aspiration is a process where the air is forced through the engine instead of being compressed through a gasoline engine. This results in a better combustion and less pollution. It also increases the efficiency of the engine. The car will run cleaner and at the same time have the best gas mileage possible. Moreover, it gives a smoother engine sound. These advantages make them more than worth the investment.
Typically, the combustion chamber of the naturally aspirated engine has two ports – one for the gasoline and the other for the diesel. On modern engines, the ports are almost always two parallel cylinders that move in opposite directions of each other. An air flow occurs in the middle of these two ports. Some engines make use of dual port technology to improve efficiency.
The oil is used to control the process of dual port technology. The oil is pumped from one port to the other. When it comes to power, the engine in the naturally aspirated version is fitted with several more features to make it better. The intake manifold is designed differently, the exhaust manifold is made to carry more oxygen and other characteristics that are important for producing good vehicle engine power. The size of the cylinders are also enlarged to increase the compression ratio of the oil. Compared to the petrol engine, the natural engine produces more power. This is attributed to the fact that it produces more engine horsepower when the air flows through it and when the exhaust gases reach the compressor the torque increases.
For the fuel consumption, the piston rings that are used on a gasoline engine are replaced with a different set of rings. They also produce more engine horsepower, more cylinder pressure and produce more oil and other characteristics that are important for producing great engine power.
