same-dramatic increases the force of the full speed field, in addition, many professional technicians break down the engine that is used in this way, and they discover that the engine is actually better than the traditional way of using the car Master manual.
The reason this is so controversial is that this article is contradictory to this article from some of the previous references to running-in articles.
There are a couple of factors that make the old information about running-in obsolete, t
smaller than that of the same power. Therefore, modern cars do not use steam engines.By contrast, an internal combustion engine is more efficient than a gas turbine, cheaper than an electric vehicle, and easily added to fuel. These advantages enable most modern cars to use reciprocating internal combustion engines.second, combustion is the keyThe car's engine generally uses 4 strokes. (Mazda's rotor engine is not discussed here, car pictorial has been introduced)4 strokes are: intake, compressi

Voice principle:Lip Spring Music music instrument by lip vibration pronunciation. when the lips vibrate, the air flow is blown into the tubular body through the cup-shaped mouth, so that the air in the tube is vibrated and pronounced. The length of the pipe is changed by the Opening and Closing piston device or the scaling pipe to get different pitch, in addition, it is

It can not only sail at high speed on the water surface, but also walk in the grass and cement square. Currently, in the maritime model competition, the and B Round racing boats model, F1, F3-v level temperature controlled racing boats, FSR level remote control endurance racing boats and F8 level remote control meters straight l
The rising oil price forces consumers to pay attention to the fuel consumption issue. For gasoline, Will 97 # Be more fuel-efficient than 93? What are the consequences of accidental mixing of the two types of fuel? I believe everyone would like to know.
1. To understand the differences between 93 # And 97 #, it is necessary to first understand some basic concepts:
1. compression ratio:
The first standard for automobile selection of gasoline labels is the engine compression ratio, which

Basic Structure of Automobile
Modern cars are composed of multiple devices and mechanisms. The basic structure of vehicles produced by different models, types, and manufacturers is composed of four parts: Engine, chassis, electrical equipment, and body.(1) Engine
An engine is a device that powers an automobile. Its role is to make fuel combustion generate power, and then drive the car through the chassis drive whee
, this is a very simple truth, is nothing more than the middle school learned the force and arm of the relationship, such examples are many, in short, if the force is not changed, want to increase the torque, the only way is to grow the arm."The car steering wheel is a typical example of increasing the torque by adding a lever."In a piston engine, the piston is reciprocating, and the crankshaft rotates, and
limit the axial motion range.
C. Joint deceleration: when a connection moves closer to its limit (set by), it produces resistance motion. This subtle effect can soften the reverse movement and avoid over-rigid motion. For example, when the piston rod runs at one end of the piston sleeve, the speed of movement is reduced.
D. damping: damping is one of the factors used to precisely adjust the reverse linka
diesel engine, the clean air filtered by the air filter is fully mixed with the high-pressure atomizing diesel fuel sprayed by the nozzle. Under the piston's uplink extrusion, the volume decreases and the temperature increases rapidly, reach the diesel fuel point. Diesel fuel is ignited, mixed gas burning, rapid expansion of the volume, push the piston downstream, known as the "work '. Each cylinder works in sequence, and the thrust acting on the

The so-called automobile exhaust volume: refers to the cylinder's working volume refers to the gas volume swept by the piston from the inner point to the inner point, also known as the single cylinder displacement, which depends on the cylinder diameter and piston stroke.
The engine displacement is the sum of the working volume of each cylinder, which is generally expressed by (l. Engine displacement is
