The engine gap is widening again?

In addition, there is another bug in the three-cylinder engine, that is, the engine noise is loud. Although nowadays manufacturers reduce noise by adding soundproof covers in the engine compartment and using better soundproof materials in the cockpit.

Automobile companies adopt different engine technologies. First of all, the technology of the engine is different. Only the new and old models of the same model have the same displacement.Due to the technological upgrade, there may be a gap of tens of horsepower. For example, Trumpchi M8 is equipped with its own 320-ton engine, adopts multi-point electric injection technology, with a displacement of 0 and a maximum horsepower of 201.

Multi-point injection and in-cylinder direct injection are used according to different situations, which further widens the gap between the combustion efficiency of the stamping engine and the fuel consumption of domestic cars. Valve control refers to valve control. Valve control is similar to controlling the breathing of the engine. There are two main aspects. The valve timing and the valve lift. The valve timing refers to the time when the valve opens and closes.

The largest engine in the United States was born, with a thrust of more than 60 tons

The largest engine in the United States The motivation was born, with a thrust of more than 60 tons. The engine is the heart of the machine, which is very important to the performance of the machine. Like an aviation engine, the greater the thrust, the stronger the load capacity. The world's largest aviation engine is the GE9X developed by the United States, with a thrust of more than 60 tons.

GE90 engine is a high-channel ratio commercial super-large thrust turbofan engine developed by GEAE (General Electric Aviation Engine Company) under General Electric Corporation (GE).

The first stage is 2 meters long and consists of 6 boosters. The center is an oxidizing tank with a large diameter, surrounded by 6 fuel tanks, with a take-off thrust of about 1,000 tons. The second stage is 17 meters high, equipped with 4 engines and a total thrust of 240 tons.

Excuse me, what is the engine model of the main fighter in the United States?

1. The F22A fighter developed by the United States is a heavy air-based fighter; the aircraft is equipped with two Pratt Whitney's F119-PW-100 boosted turbofan engines. The thrust of a single unit can reach 157 kN, and the thrust-to-load ratio can reach 10. When the force is not turned on, the plane can cruise at supersonic speed for about half an hour.

2. The full name is F119-PW-100, which is a double-rotor small-channel ratio-enforced turbofan engine developed for the F-22A. It adopts a two-dimensional vector nozzle that can be deflected up and down. The up and down deflection angle is 20 degrees, and the thrust and vector are controlled by the digital electronic system.

3. F135 turbofan engine: a new engine developed by Pratt Whitney in the United States. The F35 stealth fighter in the United States is the F135 engine equipped with it. This engine has the highest technical level in the world, with a thrust of nearly 20 tons, a 10% reduction in fuel consumption, and great development potential. .
