Q: Known engine speed, gear ratio, how to calculate the maximum speed of the car: Is the opportunity to consider the resistance below this value, is the driving force and resistance of the intersection (balance).

Q: Why China does not have advanced aero engines, ship engines, and even the world's leading car engines are not?: Western Europe, Scandinavia, etc., can produce world-class ship engine, Russia and other countries can also be manufactured, but the technical level to the West a chip.

Q: What is the NA engine?: The internal combustion engine can be divided into a naturally aspirated (non supercharged) engine and a forced intake (supercharged) engine in accordance with whether the intake system adopts a pressurization mode. The gasoline engine often adopts natural suction; the diesel engine adopts supercharged type to increase power.

Q: The car's engine trouble light is on. What should I do about it?: 3, inside the engine cylinder is not clean, after a certain time of the product inside the engine must accumulate some carbon, the carbon itself will lead to the engine design parameters change, while its unstable properties, heat accumulation, the accumulation of heat will cause the engine ignition disorder, causing the engine knock. In this case, the engine trouble lamp lights up

Q: Is China really a country that doesn't build an engine?: At present only made a very top engine, to reach the ideal state. But now it has touched the threshold, look at it, not a few years, will advance in this field, developed the top of the engine, and then there is no known Troll what happened, they can wash sleep.

Q: Kart engines are: In addition to this, the person under centrifugal force, said it was not clear who, who knows, this is the need to exercise, if you don't exercise, directly open the two, down is not sore, also may be injured, CKC, is the front and rear brakes, ordinary frame is only after brake. The above are not hung, and the country's top Kart Race is 30 horsepower models

Q: What are the six engines?: As the engine mechanism, the engine system with the installation and the matrix itself is composed of many parts, such as the crank link mechanism, a gas distribution mechanism, fuel injection system, cooling system, lubricating system components. Therefore, it is difficult to distinguish the parts of the engine from each other strictly. In addition, the airframe is a mechanical part that is subjected to high temperature and high pressure.

Q: Is the engine an engine?: Meanwhile, the huge pressure of the explosion gas pushes out the vent of the one-way valve and discharges the exhaust gas. Then, the residual air in the cylinder becomes colder and the pressure becomes low, and the atmospheric pressure at the outside of the cylinder pushes the piston downward to prepare for the next explosion. That's the simple principle.

Q: Cloud 490 engine how: Cloud 490 engine is the Kunming cloud Power Co., Ltd. production, the company's current assets of 550 million yuan, with an annual output of more than 10 million units of various types of diesel production capacity.

Q: What are the differences between front and rear engines?: The difference is simple, the front is the engine in front of the body, and the rear is the engine behind the body! Front engine is the most common design, the advantage is to use the airflow when driving cooling, and if with the front wheel drive is a good way to save costs, but also in the accident in the driver's safety advantage.
