Product Description:

Guangxi Yuchai Machinery Co., Ltd. (NYSE: CYD) is the core subsidiary of Guangxi Yuchai Machinery Group Co., Ltd., with over 9,000 employees, total assets of over 16 billion yuan and an annual engine output of 500,000 units. We completed the shareholding reform in 1992, became a Chinese-foreign joint venture in 1993 through restructuring, and went public on the New York Stock Exchange in 1994 as China's first engine manufacturer listed abroad. Headquartered in Yulin, Guangxi, we have 8 subsidiaries and production bases in areas such as Fujian, Jiangsu, Anhui and Shandong and Inner Mongolia.

Q:W12 engine and V12 engine which strong? The
V-type arrangement: the cylinder was two columns, installed in a crankshaft, two cylinders for the V-shaped arrangement, hence the name, a little bit for the small size, but the higher cost.
Q:What is the car engine displacement
The displacement of the car refers to the sum of the capacity of all the cylinders of the engine.
Q:Does the car change natural gas to the engine?
In the aspect of engine structure, the main factor that determines the engine power is the compression ratio of the engine. The greater the compression ratio, the higher the thermal efficiency, the greater the effective power. At the same time, the greater the compression ratio, the greater the tendency of the engine to knock. Therefore, the engine compression ratio must also be adapted to the antiknock performance of the fuel. The antiknock performance of gasoline determines that the compression ratio of gasoline engine can not be too large, but the antiknock ability of natural gas is very good, and it can be used to compress relatively large engine, thus increasing its power.
Q:Engine arrangement...
2.V type, that is, the cylinder is divided into two groups, alternating installation on the same crankshaft, but two of an angle (more than 90 degrees or 70 degrees). The utility model has the advantages of compact volume and little vibration.
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 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: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:Does the car engine start or start?
So we often say that the starter (let the engine turn the machine), start the engine, the car starts
Q:What is the meaning of the rear of the car engine?
It is the use of the engine exhaust gas inertia momentum to promote the turbine chamber turbine, turbine and drive the coaxial impeller, the impeller pressure sent by the air filter pipe air, so that pressurized into the cylinder.
Q:Is the load and torque of the engine the same thing?
First of all, I now correct a friend's point of view upstairs, the engine maximum torque when the number of revolutions is based on the engine design parameters vary, and not all the engines are in the same number of revolutions to produce the maximum torque,
