Compression garbage truck compression ratio means:
Compression type garbage truck is a relatively complicated model in the garbage truck series, and the price is relatively high. The compression function of the compression type garbage truck mainly adopts the compression function of the relatively large-size living garbage, so that the density of the garbage becomes smaller, and the garbage capacity loaded in the garbage box becomes larger. Many friends have some confusion about garbage truck compression ratio and engine compression ratio.
Garbage truck engine compression ratio refers to the ratio of the air fuel mixture entering the cylinder compressed by the piston, that is, the ratio of the total volume of the cylinder to the volume of the combustion chamber. In general, the compression ratio of the gasoline engine is 8-11, and the compression ratio of the diesel engine is 16 -24, to explain the technical parameters of an engine, can be roughly marked with the size of power and torque, but there are many factors affecting power, torque output, one of the important factors is the compression ratio of garbage truck engine, It represents the degree to which the gas in the cylinder is compressed when the piston moves from bottom dead center to top dead center.
The engine can generate more power, and the power is the product of torque and speed. The greater the output power of the engine, the better its power is naturally. The torque is mainly reflected in the acceleration performance of the vehicle, and some engines are adjusted into Low speed and high torque, the vehicle has a good start acceleration performance, and the garbage truck is easy to drive at high speeds at low speeds, which is conducive to fuel economy, top dead center, bottom dead center and piston stroke, and top dead center is that the piston rotates from the crankshaft The farthest point in the center is usually the piston up to the highest position, abbreviated TDC.
The bottom dead center is the most recent year when the piston is away from the center of rotation of the crankshaft. It usually refers to the piston descending to the lowest position, abbreviated as BDC. The piston stroke is the distance between the bottom dead center and top dead center when the piston runs in the cylinder. It is represented by S. The unit is mm. The piston is called a stroke from top dead center to bottom dead center. Similarly, the garbage truck piston is also called a stroke from bottom dead center to top dead center. One stroke crankshaft rotation circle is 180 degrees, complete. Four strokes (intake, compression, work, exhaust) require the crankshaft to rotate two revolutions or 720 degrees.
