Q:The cylinder inside the family type paper towel is the most practical and easiest way out
With the hands in front of the cylinder cylinder will be squeezed, compressed, then cross direction pressure in the extrusion direction just once, you can easily turn round the tube out.
Q:How big is the gap between the engine piston and the cylinder wall?
First of all, the piston is not round, and the side view is not square. This is due to thermal expansion at different parts of the piston in a high temperature environment.The local minimum gap of about 0.04, depending on the design, the smallest place probably in the piston to stop opening of the lower end of 15 to 20mm perpendicular to the piston pin position, of course not absolute, the design of the skirt length is not the same.The largest part of the gap is the fire bank, which is the place above the first ring, usually at 0,7~0.8mm
Q:What is the relationship between cylinder number and horsepower?
The power of the engine mainly depends on engine displacement and displacement speed, when the engine speed is high, the output power of the engine is improved, the speed of the engine to have the corresponding technical guarantee can work reliably in the design and manufacture.In addition, the use of supercharging technology can increase the power of more than 30% of the engine.
Q:What's the average number of cylinders in a car? What's the law?
There are usually 3 cylinders, such as xiali. There are four cylinders, that is more common, and there are 6 and 8, and look at it will understand
Q:What does the displacement of the car have to do with the cylinder?
In fact, there is no direct relationship between what, 1.0L V6 can be made in theory, but not what is necessary, because the inline engine has its own advantages, and if you do, it is bound to each cylinder can be greatly reduced, so that the engine is of no practical use! And the cost will be high!As a large displacement engine, a straight line if the space occupied by the engine will be large, so large and bulky, the car's head by the pressure is too large, the front must be extended, from a cost perspective, The loss outweighs the gain!
Q:What is the number of cylinders?
That is the intake and exhaust of the engine. It is estimated that you bought 1.6 or 2, and 1.8T has 5 cylinders per cylinder, and 20 for each. This thing is not advanced, that is, the beginning of the two valve, a little meat, and nothing else!
Q:What's the difference between a L cylinder and a V cylinder? What's the good news?
Arrangement of cylindersType W arrangement and type VMany people think like V type engine cylinder arranged in a V shape, arrangement of W engine cylinder must be in a W shape, in fact, it is only approximate W shaped arrangement, strictly speaking should also belong to V type engine, at least is a variant of V engine.The V engine of each side of the cylinder and then a small angle stagger (such as Passat W8 small angle of 15 degrees), it has become a W engine. Or W engine cylinder arrangement is composed of two small V shape, a large V shape.Compared with W type and V type engine engine can be made shorter, the crankshaft can also be shorter, so the engine can save space, but also can lighten the weight, but its width is larger, so that the engine room is full.The biggest problem with W engines relative to the V engines is that the engine is divided into two parts by a whole, which inevitably causes a lot of vibration at the time of operation. To solve this problem, the Volkswagen designed two reverse rotating balance shafts on the W engine, allowing the vibration of the two parts to cancel each other in the interior.Volkswagen has three types of W engines, W8, W12 and W16
Q:How much is the cylinder pressure of the gasoline engine lower than that of the diesel engine?
Because diesel is a compression ignition... The gasoline engine ignites the spark through the spark plug to produce an electric spark that ignites the gas mixture!Because the diesel is not easy to ignite, so the compression ignition test! Remember to go to school, teach once, put the cotton into the needle tube, press needle, cotton burning course! This is the principle of diesel fuel... So it's stressful!
Q:What is the working principle of the cylinder?
The working mode of the cylinder is divided into the suction stroke, the compression stroke, the work stroke and the exhaust stroke.Two,(1): the intake stroke the intake valve opens, the exhaust valve closes and the downward movement of the piston, a mixture of gasoline and air into the cylinder; (2) the compression stroke, the intake valve and exhaust valve are closed, the piston moves upwards, the fuel mixture is compressed; (3) stroke: at the end of the compression stroke, the spark plug the spark, fuel burning fiercely, gas of high temperature and high pressure. High temperature and high pressure gas pushes the piston downward, which drives the crankshaft to rotate and works externally;(4) exhaust stroke: the intake valve closes, the exhaust valve opens, the piston moves upward, and the exhaust is expelled from the cylinder. (schematic diagram of the following four strokes). Turn left and turn right |
Q:How does the gasoline pump the tank to the cylinder?
Carburetor is the car; its flow is; from; the tank to the oil pipe to the gasoline pump; through the gasoline to the carburetor and air atomization; fuel injection nozzle into the cylinder. The EFI engine is the sensor to signal to the engine ECU to storage, instructions to the actuator, actuator and then according to feedback data necessary adjustment, supply nozzle oil quantity into the cylinder.
