What are the best 2 0L engines in the world?

1. The power is different.

The displacement engine is smaller than the displacement engine, and the large displacement is the large energy released by the engine per unit time, that is, the power is good, so the power effect of the displacement engine is smaller than that of the displacement engine.

2. Fuel consumption is different.

Because of its small displacement, displacement engines consume less fuel than displacement engines over the same distance.

Engine displacement precautions:

1. The engine form determines the gradeIn general, according to the different displacements, the engine is divided into three cylinders, four cylinders, six cylinders, eight cylinders, and turbocharged, while L4 (inline four-cylinder engine) and V6 (V-type six-cylinder engine) and turbocharged models are more common.

2. According to the replacement cycle on the manual, you can replace it in time, generally 5000 km - 7500 kilometers to change the oil, if the car conditions are worse, you can appropriately shorten the cycle. But no matter what form of engine, it is certain that the use of fully synthetic motor oil will protect the engine in place.

3. Every once in a while, you can check the engine by yourself, open the engine cover, and check whether the engine and accessories have oil and dust, especially whether there is leakage at the joint between the cylinder head and the cylinder block, the interface of the oil filter, the air conditioning compressor, the steering power pump, the transmission shaft and other joint gaps. This will ensure that there will be no surprises on the next trip.

Engines with larger displacements have more air intake, so engines with larger displacements are more powerful, but engines with larger displacements also have higher fuel consumption and higher maintenance costs. Displacement engines are more powerful than displacement engines, but fuel consumption is also higher than displacement engines.

If you want to increase the air intake of the engine, you can directly use turbocharging technology to increase the air intake of the engine without increasing the displacement.

Turbocharging technology was not applied to the engine of a car at the beginning of its birth, but to the engine of an aircraft.

Turbocharging technology can solve the problem of insufficient air intake encountered by aircraft engines at high altitudes.

Later, turbocharging technology was widely used in gasoline and diesel engines of automobiles.

Turbocharging technology can increase the air intake of the engine without increasing the displacement.

Turbocharged engines have turbochargers, and turbochargers have exhaust turbines and compression turbines.

The exhaust turbine and the compression turbine are connected together, and when the engine reaches a certain speed, the exhaust has enough energy to push the exhaust turbine to rotate, and the intake turbine will also rotate.

When the intake turbine rotates, the air can be compressed and blown into the engine cylinder, which can increase the air intake of the engine.

By increasing the air intake, the engine can burst out with more power.

If the engine technology, layout and other are the same, and at the same speed, the horsepower and torque must be greater than the, and the fuel consumption is also higher, but according to the formula: power (horsepower) = speed torque constant, in the case of constant power, the higher the speed, the smaller the torque, I only need to increase the engine speed, the horsepower can also be exceeded, greater than is no problem, but the torque is impossible to exceed, unless the supercharger is used.

2 .5 is the sum of the volume of each cylinder of the engine, the larger the volume, the greater the power (under the technical parameters of the car meet the requirements).

The engine is often an in-line four-cylinder, and the engine is often a V-6. Displacement gap, the latter has better acceleration than the former. Cylinder type, V6 runs more smoothly and quietly.

The engine bore displacement is smaller than the displacement!

Ha, there is no regret after that, there is always something worth it.

<> "The first was a Volkswagen engine.

It uses in-cylinder direct injection technology to achieve maximum torque output at lower speeds, making it ideal for urban driving. This engine is not only used in Volkswagen brand models, but also in a large number of high-end brand Audi brands, and the reputation is very good.

The second is a BMW N20 engine.

This engine has won several top 10 titles. As we know, BMW is one of the representatives of the sex and the ability to car, in the high-end brand position has a strong appeal, and later BMW developed the latest B48 on the basis of the N20, more powerful, lower fuel consumption.

The third is a Mercedes-Benz one.

Mercedes-Benz engines are used in a variety of models, including GLA and GLC, and the power level is among the highest in luxury brands. This engine, as the standard power configuration of luxury models, has a qualitative improvement in fuel consumption control compared with previous products, changing the traditional impression of high fuel consumption of performance cars.

The fourth is the Ford engine.

As a century-old car company in the United States, Ford has always attached great importance to research and development. As an entry-level power for medium and large vehicles, it is not only used in many models of the Ford brand, but also in ace pickup trucks, and it is a pretty good engine.
