Q:What is the meaning of the rear of the car engine?
When the engine speed increases, the exhaust gas discharge speed and the speed of the chaos also increased faster, the impeller to compress more air into the cylinder, the air pressure and density can burn more fuel, the corresponding increase in the amount of fuel can increase the engine
Q:Is China really a country that doesn't build an engine?
Of course not, Chinese from scratch, by single handedly, abruptly from the world engine surrounded by blaze a trail, now in addition to the five rogue, there are countries which can involve its self-reliance (high precision CNC, avionics equipment, metallurgy, new materials and many other items are currently China the weak point of the western technology Chinese absolute monopoly
Q:How can power and horsepower be converted?
As the engine maximum power is 110KW, then the horsepower is about 147.45PS, in practice, also do not count so clearly, after you see more, estimated on the line, now the manufacturers are using the size calibration of engine power (KW) said the.
Q:What is the driving function of the brake and the engine? What do they mean?
4) auxiliary braking system - the car often traveling in the mountains and car some special purpose, in order to improve traffic safety and reduce wear and brake recession driving braking system performance, with a stable speed in the downhill. That's what you call the engine brake, also known as the engine anti - prop.
Q:Engine and motor and engine, what are the concepts?
Is the two concepts, three called, two uses: the engine is the engine of the transliteration, that is, the engine; so the engine is the engine. Motor is motor translation, the Chinese meaning motor generally refers to the motor, such as the starting motor is the starting motor.
Q:Car engines: what does V12 mean?
First, take a look at one of the most common engine parameters -- engine displacement. Engine displacement is the sum of the working volume of each cylinder of the engine. It is generally expressed in L. While the cylinder working volume refers to the volume of gas piston from TDC to BDC swept, also known as single cylinder displacement, it depends on the bore and piston stroke. Engine displacement engine is a very important parameter, it can represent more than the number of engine and the cylinder bore size, the engine of many of the indicators are closely related with the displacement. Generally speaking, the larger the displacement, the greater the output power of the engine.
Q:The two major engines and six systems
Hello, strictly speaking, the car's engine is the two big organization and five systems, and not the six systems, the two institutions is a valve mechanism and a crank connecting rod mechanism inside the engine, gasoline engine has five major systems are the fuel supply system, lubrication system, cooling system, ignition system and starting system
Q:What are the systems in the car engines?
The gasoline engine includes the ignition system, the starting system, the lubrication system, the cooling system and the fuel supply system, consisting of five major systems. The diesel engine includes: starting system, lubricating system, cooling system and fuel supply system, consisting of four major systems.
Q:The new Regal 2.0T engine and MAGOTAN 2.0T engine which is better?
First look at the data of the new Regal 2.0T maximum power 162kw/5300rpm, maximum torque 350Nm/2000-4000rpm MAGOTAN 2.0T maximum power 147kW/6000rpm, maximum torque of 280Nm/1800-5000rpm, GDI technology new Regal 2.0T dual-mode gasoline direct injection SIDI, using stratified combustion mode and homogeneous combustion mode (not MAGOTAN 2.0TSI Audi TFSI), just the basic cylinder straight the jet technology and material Regal 2.0T is double VVT, the Aluminum Alloy MAGOTAN 2.0T, no VVT is the ease of use of cast iron
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.
