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:The cylinder inside the family type paper towel is the most practical and easiest way out
On the plane where the hard pressed on the other side and then turn 90 degrees again once and then take it out
Q:What does the displacement of the car have to do with the cylinder?
You can say all you can. Technically you can do it. It's like a motorcycle 600 with a single cylinder and 250 with a 4 cylinder.However, to consider whether it is worth, the number of engine cylinders and arranged in order to maximize the form of power and maximum stability, of course, combined with cost considerations.1 of the design into V6, then the cost will increase a lot, but the advantages can not play out, it will lose meaning.6 designed to L4, the stability is much worse, affecting the comfort of the vehicle
Q:What's the average number of cylinders in a car? What's the law?
Inline four cylinder also has more inline three cylinder such as QQ Alto 1 exhaust quantity is 3 cylinder car more than 1.1 more is an inline four cylinder, there are a lot of things such as the 4 cylinder 1.1 exhaust inline four cylinder exhaust should be maximum may the most thing on the market to see the 2.4 peak is over the are also basic V type arrangement of 6 cylinder engines such as Teana. Anyway market mountain car multi part or 4 cylinder 1.6 gold displacement domestic car now for more than 1.5 1.5T but also four cylinder car, row rule is the larger the gas cylinder may response number for small cars. At present, the world cylinder maximum number production model is Bugatti Veyron EB Veyron - 16.4 the car engine is popular R & D 16 cylinder 64 valve engine, with four turbochargers, using W type cylinder layout displacement: 7993 CC in 3 seconds can make the car to reach 100 km/h speed, start to accelerate from standstill to 300 km/h speed the time required for less than 14 seconds
Q:The more cylinders, the better?
To a certain extent, the heat will be a problemA8 doesn't seem like V12, but W12 doesNo faster than R8, R8 is a sports car after all
Q:How does the gasoline pump the tank to the cylinder?
Too simple, the gasoline engine intake system and air intake valve open, gas mixture into the cylinder, high voltage coil from high voltage and the cylinder line to the spark plug ignition, ignites the mixture, the instantaneous pressure generated in the cylinder to make the piston down, turn the crankshaft, and the other is the upward movement of the piston so, the engine cycle movement.
Q:What is the number of cylinders?
The valve, as the name suggests, is the inlet and outlet of the valve. When the engine is to work, it has to burn gasoline, and when it is burning, it has air. The valve is the device that controls the intake and discharge of the cylinder. The amount of output and the performance of the engine valve number is a direct influence is undeniable, the design of multi valve intake and exhaust design and the exhaust system, for peak horsepower output absolutely has a critical impact.The valve number of the engine is generally divided into 2 valves per cylinder, or 4 valves per cylinder, and a small number of valves with 5 valves per cylinder. It is worth noting that the car parameters often in two forms of "four cylinder four valve, inline four cylinder 16 valve," said the two represents the engine is four cylinder, 4 valves per cylinder, valve number for 16The number of cylinders used in automobile engines is 3, 4, 5, 6, 8, 10 and 12 cylinders. Displacement of 1 liters below the engine, commonly used 3 cylinder (such as Xiali 7100), 1 - 2.5 liters, usually 4 cylinder engine, 3 liters or so of the engine is generally 6 cylinder, 4 liters or so for the 8 cylinder, more than 5.5 liters with 12 cylinder engine. According to the arrangement of the engine, and can be divided into W type 12 cylinder engine (such as W12, Audi A8W12, Volkswagen Phaeton), V type 12 cylinder engine (such as BMW, Mercedes Benz S600, 760), W type 8 cylinder engine (such as W8, Passat) V 8 cylinder engine (such as Audi A6L4.2), boxer 6 cylinder engine (such as Subaru V, forester) type 6 cylinder engine, inline 5 cylinder engine and inline 4 cylinder engine. Generally speaking, in the same cylinder diameter, cylinder number, larger displacement, higher power; in the same displacement, cylinder number, diameter is smaller, speed can be improved, so as to get bigger promotion power.
Q:What is the working principle of the cylinder?
The working modes of the cylinder are divided into suction stroke, compression stroke, work stroke and exhaust stroke.Working principle;1, enter (suction) gas, at this time the intake valve open, exhaust valve closed, the air through the carburetor to form a combustible mixture into the cylinder, the piston in the cylinder down straight line movement, to reach the bottom stop point;2, compression, at this time intake valve, exhaust valve closed at the same time, the piston straight upward movement, reaching the top dead center;3, doing work, when the spark plug into the combustion chamber ignition, flammable mixture explosion, the temperature rose sharply, Peng up the piston downward movement;4, exhaust, the piston through the work done after the intersection of upward straight line movement, at this time the intake valve closed, exhaust valve open. The four stroke completes a work to drive the crankshaft to rotate the output shaft power.
Q:What is the relationship between cylinder number and horsepower?
Generally speaking, when the engine single cylinder exhaust quantity is invariable, the cylinder number is more, the engine total displacement is bigger, the output horsepower is bigger.In the case of constant engine cylinder number and displacement, there are three ways to increase engine power:First, increase the speed of the engine. For example, the current F1 engine, V8, has a displacement of just 2.4 (the same as the 4 cylinder Camry). Speed up to 20000 rpm, more than 800 horsepower.Two, pressurization. Supercharging is divided into mechanical supercharging and turbocharging. For example, Fawkes's 1.8 engine had 120 horsepower, while the 1.8 - meter mass 1.8T turbocharged engine was tuned to 220 (old TT).Three, using a two nitrogen oxide (commonly known as laughing gas) instead of air into the combustion chamber. They are generally used as converted vehicles for straight speed races.
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
