Sinotruk SITRAK：The diesel, which equips dump truck china ,The diesel is a complex structure, a wide range of parts and components of the machine, but they are by a crank and connecting rod, the two institutions and the fuel supply valve train lubrication cooling, start the system and ignition system five systems (diesel engine ignition system such as point to start or incidental lighting electrical system) and a total of seven parts. These structures and systems have their own role, they are interlinked closely with the co-ordination work together to ensure the normal work of the internal combustion engine.
Crank Train engine work cycle energy conversion to complete the main moving parts. It consists of a body group, the group of the piston rod and the axis song flywheel group. In the power stroke, the piston is exposed to gas pressure within the cylinder linear motion, through a linkage to convert the rotational movement of the crankshaft, and the power from the external output of the crankshaft. In the intake, compression and exhaust stroke, the flywheel to release energy again crank rotating motion into a linear motion of the piston.
The function of the gas distribution mechanism is based on the working order of the engine and working process, the timing to open and close the intake valve and the exhaust valve, so that the combustible gas mixture or air into the cylinder, and exhaust gas is to be excluded from the cylinder, to achieve ventilation process. Most of the gas distribution agencies OHV valve train, generally driven by the valve group and valve group composition.
Start to make the system function to launch the transition from stationary state to the working state, and must be rotated by an external force of the crankshaft of the engine, the piston reciprocating combustion of the combustible gas mixture within the cylinder expansion work to promote the downward movement of the piston so that the crankshaft rotation. Engine to its own operation, the duty cycle can be automated. Therefore, the external force, the crankshaft is rotated to the idling engine start automatically the whole process, referred to as the start of the engine. Devices required to complete the boot process, referred to as the engine start system.
Ignition system in gasoline, the combustible gas mixture within the cylinder is by spark ignited, and to this end in the the gasoline cylinder head fitted with a spark plug, the spark plug head extends into the combustion chamber. All the equipment on time to produce a spark between the spark plug electrodes called ignition systems, ignition systems usually have a battery, engine, distributor, ignition coil and spark plugs and other components.
The cooling system's function is to absorb some of the heat from the heated parts dissipate in a timely manner to ensure the work of the engine in the optimum temperature state. Water-cooled engine cooling system usually consists of a cooling water jacket, water pump, fan, water tank, the thermostat.
The function of the lubrication system is conveyed to the surface of the relative movement of parts quantitative cleaning lubricating oil, in order to achieve fluid friction, to reduce friction, to reduce the mechanical wear. And parts of the surface to be cleaned and cooled. Lubrication system typically consists of lubricants Road, oil pump, oil filter and valve.
