What are the advantages of a V engine?

The disadvantage of the V-engine is that it has to use two cylinder heads, which is more complex and costly. In addition, after its width is increased, the space on both sides of the engine is smaller, and it is not easy to arrange other devices.

The V-type engine is an engine that divides all cylinders into two groups, and arranges adjacent cylinders together at a certain angle, so that the two groups of cylinders form a plane with an angle, and the cylinders are V-shaped when viewed from the side. The V-engine's small height and length make it easier to arrange on a car. It facilitates the increase in displacement and power by enlarging the cylinder diameter and is suitable for higher cylinder counts.

At present, many of the domestic mid-to-high-end models use V-shaped 6-cylinder engines, such as Regal, Passat and Audi A6 and so on.

The height and length of the engine are small, which makes it easier to arrange them on a car. V stands for the V-shaped arrangement of the engine cylinders, which is generally 90 degrees, which can offset the vibration during operation and is more stable.

The V-engine is a better match for cost and performance. In this type of engine, all cylinders are divided into two groups, and adjacent cylinders are arranged together at a certain angle, so that the two groups of cylinders form a plane with an angle, and the cylinders are V-shaped when viewed from the side. Since the cylinders are staggered from each other, it is convenient to increase the displacement and power by expanding the cylinder diameter and is suitable for higher cylinder counts.

Its opposite arrangement can also cancel out some of the vibrations, making the engine run more smoothly. Because of its small height and length dimensions, the V-engine is more convenient to arrange on a car. In addition, the overall length of the engine is shortened, leaving more space for the cockpit.

As a result, the V-engine is favored by many high-end cars, and the V6 is called "the entry-level symbol of high-end cars" by connoisseurs. Upstarts in the premium car camp, such as the new Teana and Audi A6, all use this engine. Hope.

Hello, the advantage is that the height and length dimensions are small, which is more convenient to arrange on the car. The lower height lowers the bonnet height and reduces wind resistance. The shorter length allows for more space in the cockpit.

The cylinders have been staggered from each other, which facilitates the increase in displacement and power by enlarging the cylinder diameter and is suitable for higher cylinder counts.

Modern cars pay more attention to aerodynamics, requiring the car to have as small a windward side as possible, which means that the engine cover is as low as possible. In addition, if the engine length is shortened, more space is left in the cockpit. Since the cylinders are staggered from each other, it is convenient to increase the displacement and power by enlarging the cylinder diameter and is suitable for higher cylinder counts.

In addition, the V-shaped engine cylinders are arranged in opposite directions, which can also counteract some vibrations, making the engine run more smoothly.

The VVT engine is equipped with a control and actuation system that adjusts the phase of the engine cam, so that the opening and closing time of the valve changes with the change of engine speed, so as to improve the charging efficiency and increase the engine power.

The amount of incoming air is optimal, and the combustion efficiency is improved. VVT engine schematic The vane-type VVT i controller consists of a tube casing that drives the intake camshaft and an impeller coupled to the intake camshaft.

The oil pressure from the advance or lagging side oil duct is transmitted to the exhaust camshaft, causing the VVT I controller casing to rotate to drive the intake camshaft, continuously changing the intake timing. When the oil pressure is applied to the advance side oil cavity to rotate the housing, the intake camshaft is rotated in the advance direction;

VVT Engine Principle:

Variable valve timing system (VVT, VariableValvetiming), which adjusts the phase of the engine cam through the control and actuation system, so that the opening and closing time of the valve changes with the change of engine speed, so as to improve the charging efficiency and increase the engine power.

VVT technology has a history of more than 30 years, and in 1980, Alfaromeo used VVT technology for the first time; Honda, in 1989, used VVT technology with variable valve lift capability for the first time; BMW, in 2001, replaced the conventional throttle for the first time with VVT technology.

The principle is to adjust the intake (exhaust) volume, valve opening and closing time and angle according to the operation of the engine, so that the amount of incoming air reaches the best value and improves the combustion efficiency. The advantages are fuel saving and large power-to-lift ratio; The disadvantage is that the torque in the middle section is insufficient.

VVT technology can save energy and reduce emissions. The same engine, the one with VVT is definitely better than the one without. There is no comparison between different series of engines, you know.

Let's give you a link, there's a detailed introduction there.

What are the advantages and disadvantages of the VVT engine? A lot of people don't know what a VVT engine means yet. Now let's take a look!

1.Refers to the fact that the engine is equipped with "Variable Valve Timing System" technology. VVT (Variable Valve Timing) is a variable valve timing system.

The system adjusts the phase of the engine cam through the control and actuation system that makes the opening and closing time of the valve vary with the change of engine speed, thereby improving the charging efficiency and increasing the engine power.

Technology has been around for more than 30 years. In 1980, Alfaromeo first used the VVT technique for chiropractic.

3.Honda first used VVT variable valve lift technology in 1989.

4.BMW first used VVT technology in 2001 to replace the traditional throttle lift.

l Engine advantages: simple structure, stable performance, convenient maintenance, low manufacturing cost. Preferred for most four-cylinder engines.

l Engine disadvantages: not suitable for design as a large displacement engine, the volume will be too long. Generally, the vast majority of L engines are four-cylinder, and very few are three-cylinder, only BMW has an in-line six-cylinder engine in the world, and only Volvo has an in-line five-cylinder engine in the world.

Moreover, compared with the V-type engine, the vibration is greater and the noise is greater.

Advantages of V-engine: good stability, low noise, space saving.

Disadvantages of V-type engine: complex structure, troublesome maintenance.

Nowadays, in addition to the common L and V models, there are also W types, Subaru's famous horizontally opposed engines, and Mazda's rotary engines.

The V-type engine is powerful, the general V-type engine is a six-cylinder engine, the displacement is large and the horsepower is sufficient, the stability is similar to the in-line four-cylinder engine, the advantages of the in-line four-cylinder engine occupy a small space, poor power, good stability, fuel saving. I hope it can help you, and I hope to adopt it.

On the market, the number of cylinders commonly used in automobile engines is cylinders. Generally speaking, with the same cylinder diameter, the more cylinders there are, the more gasoline can be burned at one time, the more energy is generated, and the higher the output power of the engine.

First, in terms of advantages.

1. V-shaped engine: it is more convenient to arrange on the car, and the engine runs smoothly.

2. L-type engine: stable, low cost, simple structure, good operation balance, small size, high stability, good low-speed torque characteristics, low fuel consumption, compact size, and wide application.

Second, the disadvantages.

1. V-shaped engine: two cylinder heads must be used, which is more complex in structure and higher in cost.

2. L-type engine: when the displacement volume and the number of cylinders increase, the length of the engine will be greatly increased.

Hope it helps.

V-type engine refers to the division of all cylinders into two groups, the adjacent cylinders are arranged together at a certain angle, so that the two groups of cylinders are pure into two planes with an angle, and the cylinders are V-shaped from the side, so it is called V-shaped engine. Its advantages are as follows: 1. Stable operation (for V6, V8, V12) and space saving.

2. The height and length are small, and it is more convenient to arrange them on the car. The lower height can lower the hood height and reduce wind resistance. The shorter length allows for more space in the cockpit.

The cylinders have been staggered from each other, which makes it easier to increase the displacement and power by expanding the cylinder diameter and is suitable for higher cylinder counts.

Advantages: The height and length are small, and it is easy to arrange on the car. The lower height lowers the bonnet height and reduces wind resistance. The shorter length allows for more space in the cockpit.

The cylinders have been staggered from each other, which makes it easy to increase displacement and power by expanding the cylinder straight, and is suitable for higher cylinder counts.

Disadvantages: The use of two cylinder heads, complex structure, high manufacturing cost. The engine width is larger, and the space on both sides becomes smaller, and it is not easy to arrange other auxiliary devices. Ridges.
