Maserati has made great progress in the pursuit of speed. 106 years ago, Maserati was born in Bologna, Italy. Since then, Maserati has made countless brilliant achievements on the road and on the track. In the constant ups and downs, Maserati has gone through a wonderful century with the strength and vitality given by Poseidon's trident.

Who knew that Maserati competed more than 20 years before Ferrari? All dreams began with a brand-new single-cylinder engine designed by Carlo Maserati at the age of 17. In the long history of Maserati, engine technology has always been the key point to lead it forward. During this period, many famous engine models and leading technologies were born.
During World War I, my brother Alfieri designed a patented spark plug and matched it to the famous SVA plane. With years of experience in engine research and development, Alfieri began to devote himself to motor racing, because only harsh motor racing can test the true strength of technology. 1932, Tipo made its debut? V5 has been a great success. Then, legendary driver Novara Leigh won several grand prix titles by driving Maserati 8CM. 1938 Maserati 8CTF fixed cylinder head 8-cylinder engine racing car was unveiled, equipped with an in-line 8-cylinder engine with a maximum power of 365 HP. Won the game in America immediately. The experience and technology brought by racing cars have also been applied to civilian vehicles.
After World War II, Maserati's first civilian car A6, the first prototype of the GranTurismo sports car series, was a six-cylinder car designed by Pininfarina herself. 1500 shines brilliantly. It is driven by a 1488cc inline six-cylinder engine, equipped with single overhead camshaft and Weber carburetors, and can produce a maximum of 65 horsepower (48kW). Engine front, top speed of154 km/h. ..
In 1950s, Maserati took an active part in Formula One Grand Prix, and the famous racing car 250F won the championship as soon as it appeared. What is the maximum output power of an inline six-cylinder engine? 240? At the same time of horsepower, it is the highlight moment when Maserati and Ferrari compete to shine.
After quitting the car race, Maserati focused on the research and development of civilian vehicles, and the advantages from racing technology made Poseidon full of fighting spirit. During this period, the famous "Bai Meiren" 3500GT was dedicated to the "King of Iran", whose heart came from a six-cylinder engine. Then at 1959, the famous "birdcage" was born. This is the legendary Tipo? 60, and the birdcage series also won two championships in the arduous New Borg Ridge 1000 km race.
The "birdcage" chassis has brought unprecedented strength to Maserati, and a series of classic models Tipo? 60,61,63, etc. And the famous "birdcage" 75th anniversary concept car are household names. Subsequently, Maserati transplanted the engine used in the competition to the civilian car, and the Quattroporte president car was born. Poseidon's charm also conquered people from all walks of life, and Pavarotti became the owner of Quattroporte's special car.
Italian designer Giorgetto also brought Maserati Ghibli with an 8-cylinder engine, which has been selling well for nearly ten years. Then Giorgetto introduced the famous Bora and Bora's "sister"-Mellac. Boomerang, known as the boldest concept car in Maserati's history, appeared at the auto show, and the wedge shape was later imitated by a large number of sports cars.
In the 1990s, the famous coupe masterpiece 3200GT went on the market, equipped with engines produced by Maranello, and then this classic sports car successfully conquered the American market.

The "Poseidon" engine developed by Maserati is of great significance to the brand. It is announced that Maserati, as a high-performance luxury brand, has formally established a hard-core technical foundation with power as the core, ending the era of Ferrari OEM. It also marks Maserati's own positioning. When the electrification era comes and 12 and 8-cylinder engines are under pressure, the lightweight 6-cylinder engine has greater flexibility. The emission is relatively low, the power is strong, and a large space is reserved for mixed use with electric vehicles.
Since Maserati is marked with Poseidon's weapon, it is logical that this engine should be named after Poseidon. Since it is a milestone, of course, we must first express the ultimate performance. Therefore, a special technology in Formula One racing is used: turbulent jet ignition. The first model using this engine is also the ultimate model of Maserati MC20.
Turbulent jet ignition can be understood as "ignition amplifier" in structure. Therefore, it is necessary to add a special "pre-combustion chamber" structure inside the engine cylinder to wrap the direct injection fuel injection head and spark plug inside. The precombustion chamber is communicated with the main combustion chamber through a pipeline. It is equivalent to installing a "flame injector" on the cylinder, that is, a combustion chamber with a very small space including an oil injection head and a spark plug.
Poseidon engine is also equipped with a set of port injection system, which fills the main combustion chamber, also known as the cylinder, with mixed gas through the normal intake valve. This part accounts for about 98% of the fuel. The fuel injector in the precombustion chamber injects a small amount of fuel, accounting for about 2% of the fuel. Because the space of the pre-combustion chamber is in a relatively independent state, when igniting, the spark plug in the same chamber is ignited first, and then the burning flame passes through the small hole to ignite the mixed gas in the main combustion chamber. Due to the rapid expansion of the gas in the precombustion chamber due to combustion, flame turbulence is formed under the guidance of the channel, and it strongly flows into the main combustion chamber, forming an efficient homogeneous combustion state close to that of a diesel engine.
The purpose of this technology is to make the turbocharged gasoline engine run at higher speed and compression ratio, and give full play to the limit performance close to the ideal state of homogeneous combustion. On the MC20, the power output of Poseidon engine is as high as 630 horsepower, which is equivalent to 2 10 horsepower per liter, and the adaptive speed is as high as 8000 rpm. The torque is as high as 730 Nm, and the corresponding minimum speed is only 3000 rpm.
When expanding the border upwards, we must ensure that the territory below is not lost. Poseidon engine is still equipped with main combustion chamber ignition system. Therefore, it actually has dual spark plugs and dual fuel injection heads. Because the precombustion chamber is located in the middle of the top of the cylinder, the spark plug of the main combustion chamber is installed laterally. When the engine is at low speed and low output, adopting common port injection and traditional ignition mode can make the exhaust emission cleaner, the engine run more smoothly, the combustion is fully guaranteed, and the risk of carbon deposition is reduced.

Today, with the popularization of electrification technology, the traditional engine seems to be "youthful", but Martha has launched a brand-new "Nettuno" Poseidon engine, and it is the strongest turbocharged engine in history. This can not help but shock the fans, Maserati once again stood at the peak of the automobile industry.
For traditional luxury cars, it is never difficult to have a high-powered engine. Just increase the displacement and increase the number of cylinders. Bentley 6.75 liter V8 and Ferrari 6.5 liter V 12 are the products of this idea. However, with the advent of the era of small-displacement turbocharging, luxury cars have also "compressed" the displacement to 3.0-liter six-cylinder and 4.0-liter eight-cylinder (both are integers, because they can be cut according to the proportion of the number of cylinders, and many brands of 1.5-liter three-cylinder, 2.0-liter four-cylinder and 3.0-liter six-cylinder single-cylinder structures are similar, thus reducing the research and development and manufacturing costs). The 4.0-liter engine is fine. After deep pressurization, it can exceed 600 horsepower and can be put into train super-running. However, the 3.0 upgraded version of the supercharger is often only 400+ horsepower, even though Porsche's 2.9T is already very powerful, that is, 450 horsepower. Alfa four-leaf clover is even more powerful, reaching 565,438+00 horsepower, but it is still a little short of the top sports car. The Maserati Poseidon engine, with a displacement of 3.0, releases 630 horsepower and 730 Nm, which greatly exceeds the existing level. The Martha MC20 sports car with Poseidon engine, which will be launched in September, is also worth looking forward to.
Behind extraordinary power is extraordinary technology. In addition to increasing the displacement, the traditional engine also needs to increase the power, that is, increase the supercharging and increase the compression ratio, but the two cannot be deeply strengthened at the same time, because knocking should be avoided. For example, the engine of Ferrari 488Pista has been supercharged to a high degree, and the compression ratio is 9.6: 1. However, the supercharging intensity of Poseidon engine is not low at all, but the compression ratio reaches 1 1: 1, and it will not knock. The key technology is "precombustion chamber", which comes from F65438+.
Although the traditional engine burns quickly from ignition (usually in the center of the cylinder) to flame combustion to the edge of the cylinder, it still takes some time. For example, if the traditional combustion process is lit with matches, Poseidon's combustion is "sprayed" with a flame thrower. The starting point of this "spray" is the pre-combustion chamber-all the gasoline is ignited in a narrow space, and then the flame is sprayed from here to ignite the gasoline in the cylinder. It is precisely because of this rapid and thorough burning that Poseidon has such power. Moreover, in terms of turbines, in order to achieve stronger power, high pressurization is often needed. For large turbines, there should be some turbine lag. However, Poseidon engine's high compression ratio and efficient combustion will make the turbocharging value lower, and a small turbine with lower turbine lag can be used, which will have faster dynamic response and smoother response at low load.
I think Poseidon engine is not only a strong competitor of the world engine of the year this year, but also will create another milestone in the engine history. Are other brand owners who also participate in F 1 excited?

Have you read the introductions of the above three teachers about Maserati's new Poseidon 3.0T? The introduction of V6 engine makes me look forward to the arrival of a new generation of Maserati supercar MC20. Since 13 years ago, Glen? After Turismo came out, Maserati did not have a real two-door model, but began to develop four-door models, such as Quattroporte, Ghibli and levante. Although the production and sales volume has risen to a new height in the history of the brand, there seems to be a lack of some support for the sports that should be contained in the bones. The arrival of MC20 will undoubtedly strengthen the sports genes and track quality of Maserati brand again. At the same time, the MC20 with middle and rear wheel drive layout is definitely a pure sports car with Maserati's century-old racing pedigree. With Poseidon engine, it has enough capital to challenge any competitors at the same level in the market, and its design and technology represent the new direction of Maserati in the next ten or even twenty years. Now, we are looking forward to Modena's world premiere in September.
