Aston Martin DB12, still by hand-made engine in 2023

According to It is planned that the production of Aston Martin's new DB12 will begin in the second quarter of 2023 and will be delivered successively in the fourth quarter of 2023. The official retail price of DB12 in China is 2.58 million yuan. DB12 still adopts Aston Martin's iconic large-area chrome-plated horizontal bar middle mesh, and the recognition is still very high.

On the 12th, Aston Martin brought DB12's Chinese debut in Shenzhen. Aston Martin DB12'sThe release coincides with the 110th anniversary of the brand and the 75th anniversary of the DB sports car series, which is enough to show the importance of DB12 to the brand.

The full name of GT is Grand Tourer "Great Traveler". As the best representative of GT sports cars, the Aston Martin DB series is undoubtedly the most perfect GT sports car in the world, even one of them.

As a British top supercar brand - Aston Martin, its main DB series has been deeply rooted in people's hearts. Since the release of DB1 in 1948, every innovation of this model has attracted great attention. And this time, the new DB12 Volante has realized the re-evolution of the DB series with its soft-top convertible design.

How about Tinchai 4db1 engine

Yes. The parameters of the use of the Tin Chai 4db1 engine in the Wuxi Diesel Engine Factory of FAW Jiefang Automobile Co., Ltd. show that the 4DB1 engine has the traditional characteristics of low fuel consumption and low noise. At the same time, it has the advantages of long oil change cycle technology, which can replace the oil every 40,000 kilometers. Its cylinder diameter is 86mm and the displacement is 2L.

Good. In terms of performance. The Tin Chai 4db1 engine has great power and high thermal efficiency. In terms of price. The price of Tin Chai 4db1 engine is cheap, which is 9,000 yuan.

The fuel consumption of the Tin Chai 4DB1 engine varies according to many factors, including driving conditions, driving style, vehicle load, etc. Under normal circumstances, the fuel consumption of the Xichai 4DB1 engine is relatively economical, but the specific value still needs to be determined according to the actual situation.

Not bad. The fuel economy performance of the Tin Chai 4db1 engine is still relatively excellent. Compared with similar engines, its fuel consumption is relatively low, which can effectively reduce operating costs. At the same time, it also has a low emission level, which meets contemporary environmental protection standards.

How about the Doosan db58 engine?

The toolbox is large and the air conditioning effect is good, but the temperature cannot be displayed. The track plate is 600 wide, the same as that of the large excavator, which is more convenient for dredging, and the walking speed is relatively slow.

Not bad. The Revo Doosan engine adopts the world's leading diesel engine technology, which is simple in structure and has many advantages such as strong power, reliability and durability, low noise and low fuel consumption. Low-friction technology and advanced combustion airway matching technology have truly achieved green energy saving and low emissions.

Doosan 215-7 consumes 20 liters of fuel per hour. According to the relevant public information of the inquiry, Doosan 215-7 adopts a DB58T1 air-cooled engine, with a maximum fuel consumption of 20 liters per hour.

Among imported brands, it is worse than Carter Komatsu, better than Hyundai, and similar to Hitachi's.

How big is the Aston Martin db11 engine displacement

So the displacement of this car is 0 liters or 2 liters. Aston Martin db11 is a sports car under Aston Martin. The length, width and height of this car are 4,739mm, 1950mm and 1279mm respectively, and the wheelbase is 2805mm.

Aston Martin db11 has an eight-cylinder model and a twelve-cylinder model. The following is the relevant information 1 Aston Martin db11 uses a total of two engines, one is a 52-liter twin-turbocharged engine, and the other is a 40-liter twin-turbocharged engine, so the displacement of this car is 4 0 liters or 52 liters Aston horse.

Aston horseDing db11's 0-liter twin-turbocharged engine is a v8 engine, with a maximum output power of 510 horsepower and a maximum torque of 675 Nm. The engine is equipped with in-cylinder direct injection technology, using aluminum alloy cylinder head and cylinder block, and matched with an 8at transmission.

The front suspension of Aston Martin db11 uses double cross-arm independent suspension, and the rear suspension uses multi-link independent suspension. Aston Martin db11 is a sports car under Aston Martin. This car uses two engines, one is a 0-liter twin-turbocharged v8 engine, and the other is a 2-liter twin-turbocharged v12 engine.

Aston Martin db11's 2-liter twin-turbocharged v12 engine has a maximum torque of 608 horsepower and 700 Nm. This engine'sThe maximum torque speed is 1500 to 5000 rpm, and the maximum power speed is 6500 rpm. This engine is equipped with in-cylinder direct injection technology and uses aluminum-magnesium alloy cylinder head and cylinder block.

How to divide the direction when installing the db58 engine piston

1. It should be noted that the direction of the marking on the top of the piston of different series of engines is different, generally facing the front of the engine, indicated by words or arrows. However, there are also signs facing the rear of the engine, so don't install it wrongly when assembling. Secondly, when the piston connecting rod group is pushed into the cylinder and close to the piston ring, attention should be paid to the opening position of the piston ring.

2. The piston ring generally has letters or numbers, one side is facing up, there is no sign or specific direction, and the oil ring is not divided into front and back sides.The opening of the piston ring should be staggered at an angle of 120° to prevent the combustible mixture from leaking from the gap between the opening of the piston ring when the engine is started, causing difficulties in starting the engine.

3. Forward marking: There is a mark on the piston and connecting rod, and most of these marks are forward (in the direction of the time ruler). You should know that the force points and friction coefficients in different directions are different, so this forward-facing mark must be assembled in the correct direction (all towards the front of the body).

4. The piston ring generally has a letter or number on one side up. If there is no sign, there is no specific direction regulation, and the oil ring does not distinguish between the front and the back. The opening of each ring should be staggered at 120 angles to prevent the combustible mixture from leaking from the opening gap of the piston ring when the engine is started, resulting in the engine not easy to start.

5. When installing, the positive and negative can generally be distinguished by looking at the arrow logo or English characters on the top of the piston. Let's learn how to judge the installation direction of the piston. Whether the installation of the piston requires the car engine to be used for a long time, it is inevitable to need to be disassembled and overhauled.
