Many friends want to buy a car just after the motorcycle license test, but they don't know where to start, and finally have to start with the appearance. It's important to like the look of your car, but knowing what's inside can also make you more satisfied with your first car. Then the question comes, the mechanical structure of the motorcycle is so complicated, where should we start? Helmet King can give you an answer here: the engine form. We must know that the number of engine cylinders of a motorcycle has a very decisive impact on the riding experience. Therefore, today Helm King will introduce the characteristics and differences of single-cylinder, double-cylinder, and four-cylinder engines. If you have a friend who is considering buying a new car, remember to share today's article to compare it with them!

Single Cylinder

The single-cylinder engine is the simplest form of engine, simplicity and violence are the biggest features of the single-cylinder engine. Generally speaking, the torque and power of a single-cylinder engine will start to be released from low speed, and because the structure is simple (repair and maintenance costs are lower), the engine weight is not high, so single-cylinder models It feels light and refreshing to ride. Single-cylinder engines are usually used in models of 700c.c. or below, and because of the light weight of the single-cylinder itself, many off-road vehicles also use the single-cylinder form. However, there are still some sports street bikes with single-cylinder engines such as the KTM 690 Duke, and the thrill of riding also attracts many riders. As for the single-cylinder engine, the disadvantage is that it cannot be extended to a higher speed, and the vibration of the engine at high speed may also make the rider feel uncomfortable.

Double Cylinder

A twin-cylinder engine is an engine with two cylinders. Through different arrangements (parallel, V-shaped, horizontally opposed, etc.), and different engine adjustments such as ignition sequences, the tonality of the twin-cylinder engine can achieve great diversity. sex. But generally speaking, the common "parallel twin cylinder" engine has the characteristics of balanced performance in all aspects. Running will use a parallel twin-cylinder engine. Moreover, compared with a single-cylinder engine, a twin-cylinder engine will run more smoothly and have less vibration.

Another type of twin-cylinder arrangement is the "V-twin". The V-twin engine will have different characteristics depending on the angle between the engines. Generally speaking, the smaller the included angle of the engine, the stronger the torque output of the engine at low rpm, and the weaker the output at high rpm. And if it is a V-shaped twin-cylinder engine with a 90-degree included angle, the performance will be very crazy. It can maintain the output of torque at low and high speeds. With the power extension at high speeds, it is the favorite of many performance fans. But it's usually only seen on some expensive performance cars.

Four Cylinder

The four-cylinder engine almost represents "performance" in the motorcycle circle. It is important to know that all factory cars in MotoGP currently use four-cylinder engines. Why is the four-cylinder engine almost linked to performance? This is because one of the characteristics of the four-cylinder engine is its high speed and excellent power extension, and it can release the maximum horsepower at high speeds, even in the ultra-high speed range. However, relatively, four-cylinder engines usually give up low-rotation torque and low-to-medium-rotation horsepower, so if the general daily road needs may make the knight feel powerless. Therefore, four-cylinder engines are usually used in purebred sports cars that are most suitable for expressing themselves on the racing track. In addition to the exciting power, the sound of the four-cylinder engine is also one of the reasons why many car enthusiasts are eager for it. However, compared with single-cylinder and twin-cylinder engines, four-cylinder engines are heavy, bulky, and fuel-intensive, and the maintenance costs are generally higher than single- and twin-cylinder engines. Therefore, although many riders will admire the four-cylinder model, it is not suitable for everyone.

Three cylinder

If there is a simple description of the characteristics of the three-cylinder engine, it is that it balances the characteristics of the two-cylinder and four-cylinder engines. In other words, the three-cylinder engine makes up for the lack of low-speed torque of the four-cylinder engine and has better power extension than the two-cylinder engine. However, there are fewer cars with three-cylinder engines on the market. The two sports street cars, YAMAHA MT-09 and TRIUMPH Street Triple are more accessible on the market.

Six-cylinder

Finally, perhaps many riders who are familiar with motorcycles have rarely seen and heard of the existence of six-cylinder engines. The biggest feature of the six-cylinder engine is "smooth and stable". The center of gravity of a car equipped with a six-cylinder engine will be very low and stable, plus the horsepower output and throttle response are quite smooth from low to high speed, and it is too comfortable to drive. However, due to the huge displacement of the six-cylinder engine, it is usually only used in station wagons for long-distance travel. There are still models with six-cylinder engines on the market, and almost only the famous station wagon representatives HONDA Goldwing and BMW's travel flagship K 1600.

Summary

To sum up, the form of the engine affects the "personality" of a motorcycle to a large extent. If you can choose the most suitable car according to your own car needs, I believe you will love riding a motorcycle even more. And each engine form has its advantages and disadvantages, I hope you choose what you love, love your choice!
