Q:What brand and model engine are used in Audi, R8 and Audi TT?
Audi R8 uses a V 8 cylinder engine, engine model: BYH; Audi TT uses: inline 4 cylinder turbocharged engine, engine type: EA113.
Q:What about the BYD F3 engine?
F3 I often drive, drive others, the engine is BYD independent research and development of BYD473QB engine, in the entry-level car, power is very good, fuel consumption is not high. The main thing is that the engine has been 6 years old and has been tested.
Q:Does the car use engine brakes to increase fuel consumption?
2, the use of engine brake is to lift the accelerator pedal, but do not step off the clutch, the use of the engine compression stroke compression resistance, internal friction and intake and exhaust resistance to the drive wheel to form a braking effect.
Q:An internal-combustion engine for an automobile engine
The intake stroke (intake stroke) on the crankshaft piston driven by the TDC to bdc. At this point, the intake valve opens, the exhaust valve closes, and the crankshaft rotates 180 degrees. In the process of moving piston, the cylinder volume increases, the gas pressure in the cylinder decreases from PR to PA, the cylinder to form a certain vacuum, the mixture of air and gasoline through the intake valve is sucked into the cylinder in the cylinder, and further mixed to form a combustible mixture. As the intake system has resistance, the air pressure at the end of the cylinder is less than the atmospheric pressure P0, or pa= (0.80 ~ 0.90) p0. The temperature of the combustible mixture entering the cylinder is increased from 340 to 400K due to the heating of the high temperature parts such as the intake pipe, cylinder wall, piston top, valve and combustion chamber wall, as well as the mixing with residual exhaust gas.
Q:What is the engine ECU?
ECU (Electronic, Control, Unit) electronic control unit, also known as "driving computer", "on-board computer" and so on. From the purpose of use, it is a special microcomputer controller for automobiles. It is also called a single chip microcomputer for automobiles. Like ordinary microcontrollers, it consists of microprocessor (CPU), memory (ROM, RAM), input / output interface (I/O), analog to digital converter (A/D), and large scale integrated circuits such as shaping and driving.
Q:How long will the car engine be maintained?
(Every 30,000 km) to replace the fuel filter; 4, regular (30,000 km) maintenance tank cooling network; 5, regular (40,000 km or driving conditions) to replace the spark plug.
Q:How many kinds of jet nozzles are there?
A swirl device is arranged in the centrifugal injector, and the working principle is shown in the diagram. The fuel into the swirl chamber from the tangential hole, rotates rapidly in the swirl chamber, the fuel ejected from the nozzle hole, affected by the inertia force and the impact force of the air burst into numerous small oil droplets, so as to obtain the good atomization results.
Q:What is the problem of engine torque failure?
According to your feedback, it may be caused by clutch slipping. It is suggested that you contact the local 4S shop for inspection and maintenance. Torque sensor can consult Lan Ling technology procurement.
Q:Why is the engine hot car difficult to start
(1) for fault self-diagnosis. If the fault code, according to the fault code to find the corresponding cause of the malfunction. (2) Check the vacuum of the intake pipe at idle. If the vacuum is less than 667 kPa, indicating that the air intake system has air leakage, should check the inlet pipe joints, pads, vacuum hoses, etc., as well as exhaust gas recirculation system, fuel evaporation recovery system.
Q:What does engine brake deceleration mean?
2, downshift method: refers to the steep slopes or continuous downhill vehicles will change into a lower gear, in order to control the speed of the driving mode is a kind of driving method. The experienced driver used. Because of the use of long time downhill braking will cause the brake, brake disc the temperature rises rapidly, the higher the temperature the braking effect is bad, even the brake failure risk. Using the method can better control the speed, reduce the brake braking time, prolong the service life of its braking system, of course, the most important thing is to improve driving safety, avoid the occurrence of safety accidents.
