    Second - hand loader power system - classification of diesel engine
    Public date:2019-6-1   Hits:8147
    Summary of a.
    Second-hand loader power system generally refers to the diesel engine system, which provides power for the loader to run and work normally. Second-hand loaders are widely used as the power of diesel engine, which is due to its good economy, adaptability and strong power stopping characteristics.
    Classification of diesel engines
    According to the forms of the main components which convert thermal energy into mechanical energy, the automotive internal combustion engine can be divided into two categories: active cooling internal combustion engine and gas turbine. The former can be divided into reciprocating piston type internal combustion engine and rotary piston type (rotor type) internal combustion engine. Most of the diesel engines used in loaders are reciprocating piston internal combustion engines. The following focuses on the classification of reciprocating piston diesel engines. According to different classification methods, the diesel engine mainly refers to reciprocating piston internal combustion engine and can be divided into different types.
    (1) according to the number of piston strokes per cycle
    Diesel engine can be divided into four stroke diesel engine and stroke diesel engine according to the number of trips needed to complete a working cycle. Crankshaft turns two turns, the piston in the cylinder up and down reciprocating motion four strokes, complete a working cycle of the internal combustion engine known as the four-stroke diesel engine: crankshaft turns one turn, the piston in the cylinder up and down reciprocating motion two strokes, complete a working cycle of the diesel engine known as the two-stroke diesel engine.
    (2) according to different air intake modes
    School admission in a different way can be divided into the glorious oil machine and the toughening of tea oil machine oil machine is equipped with the supercharger, air through the last in the heart of the jiang increase Ren Qi raise pressure is increased under type oil machine, the central machine is equipped with environmental transformer, air suction by the words the guest role in cylinder are called I supercharged diesel engine or natural absorption "diesel engine
    (3) according to different cooling methods
    Diesel engine can be divided into water-cooled diesel engine and air-cooled diesel engine according to different cooling methods. The water-cooled diesel engine is cooled by circulating coolant in the cylinder block and cylinder head cooling jacket as the cooling medium. The air-cooled diesel engine is cooled by the air flowing between the cylinder block and the radiator fin on the outer surface of the cylinder head. The water-cooled diesel engine has the advantages of uniform cooling, reliable operation and good cooling effect.
    (4) classification by number of cylinders
    According to the number of cylinders, diesel engines can be divided into single-cylinder diesel engines and multi-cylinder diesel engines. A diesel engine with only one cylinder is called a single-cylinder diesel engine. A diesel engine with two or more cylinders is called a multi-cylinder engine. For example, two cylinders, three cylinders, four cylinders, five I cylinders, six cylinders, eight cylinders, twelve cylinders are multi-cylinder diesel engines.
    (5) different classification according to rated speed
    According to different rated speeds, it can be divided into high-speed diesel engines (above 1000r/min), medium-speed diesel engines (600~1000/min), and low-speed diesel engines (below 600r/min).
    The used diesel engines are reciprocating, four - stroke, high - speed, water - cooled, multi - cylinder diesel engines. Diesel engine has good economy and its thermal efficiency is generally 30% to 40%. The highest thermal efficiency is 46%. Diesel gift is widely applicable. It can meet the needs of many different USES. Diesel engine is compact in structure, light in weight and small in volume, so it is especially suitable for second-hand loaders with good maneuverability. But if overload, second-hand loader diesel engine exhaust smoke failure can occur.
    Conclusion: in addition to the general requirements of general automotive diesel engines, there are usually some new requirements due to different working conditions. For example, the second-hand loader has a great working impact, which requires the diesel engine to have higher stiffness and strength. It is required that the diesel engine has sufficient torque reserve coefficient due to the large working load and frequent short-term overload. The construction site is dusty and requires reliable air, diesel and oil filtration of diesel engine. Second-hand loader diesel engine often works under variable speed, so it is required to have good speed regulation performance. In addition, the diesel engine should meet the special requirements under the special working conditions such as cold and plateau.
