Q:What is the Changan SUZUKI shinotaku engine
K10B series high performance small displacement engine, DOHC engine, 1.0L displacement, maximum output power of 52kW, peak torque of 92Nm. The actual fuel consumption under comprehensive conditions is only 5.8L / 100 kilometers
Q:What are the countries in the world that can independently manufacture their own turbo engines?
Is the turbojet engine (turbo), or the turbofan engine (turbofan), or turboprop engine?
Q:What's the difference between the engine 1.8T and the 1.8L?
When the engine speed, exhaust gas speed and turbine speed synchronous speed, the air on the degree of compression to increase the air intake of the engine will be increased accordingly, can increase the output power of the engine.
Q:Power and torque of automobile engines
Power generally shows how fast the car can run, the greater the torque, the better the acceleration, and the torque is the strength of the car. They represent separate things
Q:Why is some engine displacement unit CC?
Expressed in cubic centimeters, the international standard stipulates that through the London Greenwich Observatory's prime meridian from the north pole to the equatorial length (ten thousand kilometers) of one ten thousandth of a meter, one meter = 100 centimeters 1 milliliter =
Q:Why China does not have advanced aero engines, ship engines, and even the world's leading car engines are not?
Second, the modern aero engine and ship engine principle of the same, but the implementation of technology on the aviation engine more sophisticated, so the production of advanced ship engine country distribution is much broader, such as the United States.
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:What is the TSI engine?
Characteristics of Turbo + Supercharge turbocharger + supercharger effect is the principle of exhaust gas turbocharger is the use of exhaust gas, the device itself does not increase engine power consumption, improve the efficiency of air power, but the drawback is usually more than 2000 rpm engine after intervention, is not conducive to accelerate, accelerate and let the inertia of turbine a response delay time.
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:What's the difference between a turbocharged and an ordinary engine?
Just one more turbine. The intake air is enlarged and the air intake of the engine is increased so as to increase the power of the engine
