Q:The engine is out of order. What should I do?.
The so-called "piston knocking cylinder" abnormal sound, refers to the piston side tapping cylinder wall generated abnormal sound. Generally speaking, when the piston top produces the axial force direction, as the piston changes from the compression stroke to the power stroke, the piston knock out the cylinder. In other words, every time when the piston passes TDC moves downward, the piston will be forced to hit the wall, causing the piston knocking fault. The piston knocking the decisive factor is the clearance between the piston and cylinder wall, piston clearance is what we say normally (Figure 5). As for the specific effect of the clearance between the piston knock, the main show the following features: when the piston clearance is too large, prone to knock, the reason for this phenomenon, is decided by the material and working characteristics of the piston. Its intuitive performance is that when the engine is cold, the piston gap is large and the knocking is loud. But as the engine temperature increases, the piston clearance will become smaller and the knocking sound will be reduced accordingly.
Q:What is the four stroke engine?
The gasoline engine runs through a cycle of four processes: intake, compression, combustion, service, and exhaust. During this period, the piston moved four strokes reciprocating between the upper and lower dead centers. Accordingly, the crankshaft rotated for two weeks
Q:Does gasoline No. 93 plus 97 cause detonation?
High compression ratio of the engine, if the use of low grade gasoline, will cause the cylinder temperature rise, gasoline combustion is not complete, the machine vibration, so that the output power down, damage to parts. Low compression ratio of the engine forced to use high mark oil, there will be "delay burning" phenomenon, that is, the pressure to the head, it is not to spontaneous ignition points, the same will appear incomplete combustion, the engine is also no good.
Q:What do you mean by driving brake or engine brake in your driving test?
Engine braking means lifting the accelerator pedal, but not pulling off the engine, using the compression resistance generated by the compression stroke of the engine, the internal friction force and the intake and exhaust resistance to form a braking effect on the driving wheel
Q:Seeking Brilliance China engine all models
There are other independent research and development (1.3'1.8T), China's self-developed 1.8T engine, is the first independent self-developed turbocharged engine, the performance is excellent, the market performance is good! 4A15 engine, the original model for TOYOTA 2SZ, displacement 1.5L, power 78kW/6000, torque 135n.m/4000 100 kilometers, constant speed fuel consumption of 5.3L, the performance is extremely superior. The engine uses VVT technology, electronic throttle, independent ignition system and other unique technologies. It is very gorgeous, and electronic throttle variable valve. 1.6 liter version using MITSUBISHI 4G18
Q:What is the engine ECU?
The simplest is the calculator of the engine. It takes the data of each sensor on the engine, then calculates the injection time and the ignition time. And control other actuators, such as idle motors, fuel pumps, etc..
Q:What are the modern systems of Beijing
The maximum output power of the 2.0L engine is 120Kw / 6200rpm, the maximum torque is 194N · m / 4600rpm; the maximum power of the 2.4L engine is 128Kw / 6000rpm and the maximum torque of 226Nm / 4000rpm.
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
Q:Submarine submarine engine exhaust when the exhaust row
Conventional power submarines are generally referred to as "diesel-electric submarines", as the name suggests, it is driven by diesel generators to generate electricity, and then the power stored in the battery, and drive the submarine is the motor.
Q:What are the dangers of overheating the engine?
Due to overheating caused by the crankshaft side rod reducer bearing seizure, piston ring fracture, cylinder, cylinder hold, shorten the service life of the engine, endanger motorists driving safety.
