Sanitation truck engine details

Sanitation truck was dedicated vehicle's most important core of garbage truck arrangement of cylinder, valve and flow and maximum power output and maximum torque. Sanitation truck offers the most key parts of the kernel,

Sanitation truck cylinders are divided into: 3, 4, 5, 6 and 8 cylinders. General displacement in 1 rose following of engine common 3 cylinder; 12.5 rose above for 4 cylinder engine; 3 rose around of engine General for 6 cylinder; 4 rose around for 8 cylinder, 5.5 rose above with 12 cylinder engine; and in equal cylinder diameter Xia, cylinder number more more, displacement more big, power more high; and in equal displacement Xia, cylinder number more more, cylinder diameter more small, speed can improve, to get larger of upgrade power.

Sanitation truck arrangement of cylinders are divided into: 5-cylinder following cylinder of the engine, the use of in-line arranged minority also has in-line 6-cylinder engine.

In-line engine cylinder into a lined, cylinder block, cylinder head and crankshaft of simple structure, low cost, low-speed torque characteristics, low fuel consumption, compact size, broader application, disadvantages are low power.

Inline 6 cylinder balancing is good, relatively small vibration; most of the 6 to 12-cylinder engine using v-shaped arrangement, v-stagger angle of the cylinder is divided into four columns, forms compact, v-shaped engine length and height of small size, very convenient to decorate.

V8 engine is very complex, manufacturing costs are high, so using less heavy V12 engine is too large, only a very few limousine.
Sanitation garbage car of valve number: domestic engine most used each cylinder 2 valve, that a intake door, a exhaust door; abroad car engine General used each cylinder 4 valve structure, that 2 a intake door, 2 a exhaust door, improve has into, and exhaust of efficiency; and abroad some company began used each cylinder 5 valve structure, that 3 a intake door, 2 a exhaust door, main role is increased intake volume, makes burning more completely. Number of valves is not more is better, 5 valve can actually increase volumetric efficiency, but the structure is extremely complex and difficult machining, using less, domestic production of the new Jetta a five-valve engine.

Sanitation truck capacity:

Cylinder displacement refers to the moves from TDC to BDC the swept volume of the gas, also known as single-cylinder engines, it depends on the cylinder diameter and piston stroke. Engine displacement is the sum of each cylinder displacement, typically used to (l). Engine displacement is one of the most important structural parameters, it is more representative than the cylinder diameter and number of cylinders the engine size, many of the indicators are closely linked to the capacity of the engine.

Sanitation truck high output power:

Maximum power output (PS) or kilowatts (KW) to represent. Engine output with speed a lot, with the increasing of speed, engine power increases, but after a certain speed, the power but declined. General instructions for use in car maximum power output and revolutions per minute (r/min), such as 100PS/5000r/min, that is, highest output power of 100 HP at 5000 revolutions per minute.

Sanitation truck maximum torque:

Output from the crankshaft of the engine torque, torque is denoted by N.m/r/min, maximum torque occurs at low engine speed range, with the increase of speed, torque will decline. Of course, choose to weigh how a rational use, existing functionality is not wasted. For example, Beijing is the need for air conditioning in summer and winter, in the choice of engine power to be taken into account when not too small; just loops in the city commute car, there is no need to pick big-horsepower engine. Economical and reasonable matching engine as far as possible.
