Q:What is the working principle of the balance shaft of the engine?
Axle balance is used to balance and reduce the vibration of motorcycle engines, in order to reduce engine vibration, reduce engine noise, extend engine life, and enhance the comfort of occupants. As a patent, which is composed of YAMAHA (YAMAHA) motorcycle first use, has received the good effect, has a balance shaft used in the construction of YAMAHA every car, this is also its characteristics and selling, in similar models, it is undoubtedly the most quiet
Q:What do you mean by these parameters of the engine?
The common cylinder number of automobile engine is 3, 4, 5, 6 and 8 cylinders. Displacement of 1 liters of the following engines, commonly used 3 cylinder, 1.5 liters or so of the engine is generally 4 cylinder, 3 liters or so of the engine is generally 6 cylinder, 4 liters or so for 8 cylinder, more than 5.5 liters with 12 cylinder engine. Generally speaking, in the same cylinder, cylinder number, larger displacement, higher power; in the same displacement, cylinder number, diameter is smaller, speed can be improved, so as to obtain more power can improve.
Q:What are the advantages of Audi's TFSI engine?
If you want to suddenly speed up, then there will be no time to mention the feeling of speed
Q:What is the aircraft engine surge
Aviation turbine engine performance to advanced, stable wide range of work, first of all need to surge margin to be large, the compressor operating point from the surge edge far.
Q:Where's the gold car engine number?
Engine number is the car VIN code, VIN is the English Vehicle Identification Number (vehicle identification code) abbreviation. Because SAE standard states: VIN code consists of 17 bit characters, so commonly known as seventeen bit code. It contains information about the manufacturer, age, vehicle type, body type and code, engine code and assembly site. Correct interpretation of VIN codes is very important for us to correctly identify the models so that they can be correctly diagnosed and maintained.
Q:Kart engines are
Domestic frame general assembly Honda 200cc, 270cc, respectively 6.5 horsepower and 9 horsepower. Different venues, and some venues to 200 plus speed limit to become an ordinary car, not a member of the car. Yes, 200 are ordinary cars, and 270 are member cars. 9 horsepower 270 is the current four stroke fastest, but how to control depends on the frame, which should be the best sq frame, with 270 of the steering accuracy, is the best choice for non professional track. But even the 9 horsepower car, in the majors, is no entry level.
Q:What are the modern systems of Beijing
Using a new generation of modern Theta-Ⅱ engine, with dual VVT, variable intake manifold and other advanced technology, theoretically can have a better fuel economy.
Q:Submarine submarine engine exhaust when the exhaust row
Conventional power submarines are generally referred to as "diesel-electric submarines", as the name suggests, it is driven by diesel generators to generate electricity, and then the power stored in the battery, and drive the submarine is the motor.
Q:What is the relationship between car displacement and fuel consumption?
In the relative sense, the size of the car displacement, and the size of the fuel consumption does not constitute a proportional relationship, such as the same 4-liter displacement of the car, fuel consumption is not necessarily equal.
Q:What is the material of the engine valve, especially the exhaust valve?
The small end of quenching, the hardness of 50H RCmin, effectively improve the small end impact resistance to pitting corrosion, because the locking groove of three groove structure, in order to cope with the work of spin, quenching slots; and the rod head material friction butt welding and weld strength, more than 81 0MPa; the surface of the rod chrome plating. The chrome layer thickness of 0.0015 0.003mm, the hardness above 600HV, ensure the valve rod wear resistance, improve service life.
