Q:What brand and model engine are used in Audi, R8 and Audi TT?

TT has been using is Audi's own R8 engine is that the 4.2 paragraph is to use their own engine but the displacement of the R8 has been out of the 5.2 displacement engine is improved after the acquisition of Lamborghini V10. But the calf also regressed

Q:Doosan engine model

Komatsu or can, the hydraulic system is the best, that is too dry work, and can not dry live, dig a earth still ok.

Q:J-20 there is no vector engine?

Insiders revealed that the current engine is to test the aerodynamic layout and Hangzhou electrical equipment used.

Q:What kind of engine is the GDI?

The study of GDI engines started in Germany. As early as 50s, Germany had a direct injection, two stroke gasoline engine to load the city, and even to the famous SL class Mercedes Benz sedan, but soon disappeared. Later German designers, both Mercedes Benz, BMW, and Volkswagen, for gasoline direct injection will take the attitude of untrammelled frown. Because according to the test, they think this kind of engine running performance is poor, the car almost can not open, exhaust gas problems can not be solved, so they stopped the development of the GDI engine

Q:What is the difference between the car's brake and the engine brake?

Simply put it: cars often say that there are three kinds of braking, 1. driving brake.

Q:What kind of engine is oil efficient?

The engine parameters -- generally the same engine cylinder number, full combustion is more efficient; and the four valve engine will be more than two valve more fuel-efficient, DOHC engine fuel-efficient than single overhead. In addition, the engine of a good linear - power increased evenly, the maximum torque appeared early, the car will be more fuel-efficient.

Q:Why is a solid rocket engine smaller than a liquid one?

The first question: at present the highest calorific value of fuel is hydrogen, and hydrogen into solid fuel is not practical. So the hydrogen fuel specific impulse over the current all kinds of fuel. The second question: can not. In order to ensure the maximum speed to the combustion of fuel, fuel and oxidizer must be mixed, can be mixed in liquid rocket engine combustion chamber but, the engine must be mixed combustion in solid surface. If the oxidant and fuel separation, will greatly limit the burning rate.

Q:What does EFI mean on the engine?

EFI is even simpler, that is, electronically controlled gasoline injection system, through the detection of engine intake control gasoline injection.

Q:Does gasoline No. 93 plus 97 cause detonation?

High compression ratio of the engine, if the use of low grade gasoline, will cause the cylinder temperature rise, gasoline combustion is not complete, the machine vibration, so that the output power down, damage to parts. Low compression ratio of the engine forced to use high mark oil, there will be "delay burning" phenomenon, that is, the pressure to the head, it is not to spontaneous ignition points, the same will appear incomplete combustion, the engine is also no good.

Q:What is the engine basic machine?

An engine (Engine) is a machine capable of converting other forms of energy into mechanical energy. Some people call the engine "the engine", in fact, the engine is a complete set of power output devices, engines (Figure 1)
