Q:How do the conventional submarines inhale and exhaust under water?

At present, the AIP system of conventional submarine can be divided into two major categories: thermal engine system and electrochemical system. The engine AIP system mainly includes the closed cycle diesel engine (CCD/AIP), Stryn (SE/AIP), closed cycle turbine (MESMA/AIP), nuclear power hybrid propulsion system (SSN/AIP); electrochemical AIP system is mainly for polymer electrolyte membrane fuel cell (PEM /AIP), including alkaline fuel cells, proton exchange membrane fuel cell. But at present the foreign technology is more mature, and has entered the practical stage, can greatly improve the submarine combat capability under the water AIP system is mainly the closed cycle diesel engine, Stryn, closed cycle turbine and fuel cell of the four. Some of these AIP systems have been successfully tested, and some have been equipped with new submarines

Q:What is engine drag braking?

For the car, is a taxiway, because not to oil, then the engine is run by the inertia of the vehicle in the drag on the consumption momentum. For large vehicles, and an exhaust brake, on the taxiway at the same time, you can also use the exhaust brake, is to use the solenoid valve to the exhaust pipe when closed, to a certain pressure to open, because the engine exhaust is blocked, the greater the holding force is more obvious, this is now in the trucks and other large vehicles generally

Q:GDI different from the ordinary engine of the three technical means is what?

GDI engine in the work of the uniformity and performance under full load have excellent performance, but also the gasoline engine cold work instability problem has also been significantly improved. GDI engine and general gasoline engine is the main difference between the location of the gasoline jet, was lit work, this form and direct injection diesel engine similar

Q:What is the meaning of the car's engine VVT, CVT?

, Reduce the fuel consumption.VVT technology is the development trend of car power.

Q:What engine is the BYD M6 engine?

BYD M6 (2 displacement models) is used in BYD's own 2 litre BYD483QB engine with BIVT variable intake system, the maximum power of 103 kilowatts, the maximum torque of 186 nm.

Q:The car has been insured. Can you insure the car engine again?

1, as a rule, the engine, as a major part of the car, has been included in the risk of car damage. In case of losses caused by collision or overturning, the insurance company shall pay compensation under the limit of compensation according to the proportion of liability. But there is also a special exemption from liability provisions, such as the damage of the engine in the case of wading alone, you can turn to the insurance company exclusions.

Q:What is the role of the engine timing belt?

Timing, that is, through the engine timing mechanism, so that each cylinder just to do: the piston just up to the top dead center, the valve just closed, spark plug just ignition.

Q:What are the dangers of overheating the engine?

A water-cooled engine normal working temperature should be 80 - 90 degrees (of course there will be nothing difficult than the home air) the temperature of boiling water will wait for parking, open the front cover for radiator, when boiling stop after add cooling water, let the engine working temperature drop.

Q:What are the performance differences between the four engines of the L, V, W, and H?

The types of engine cylinders are divided into L, V, H and W. L engine: also known as the "LineEngine" engine, which means that the cylinder is arranged in a straight line, and all cylinders are arranged at the same angle side by side into a flat surface. "Inline" is generally represented by L, followed by the cylinder number is the engine code, the modern car mainly L3, L4, L5, and L6 engines.

Q:Special technologies for automotive engines AVS?

By creating structural design, timely to the intake air quantity adjusting the original complex technological processes have been streamlined and optimized cleverly, inlet gas regulation is more accurate, the combustion efficiency than the traditional way of regulating the intake air quantity is higher, so the engine fuel consumption effectively reduced by about 7%
