Description
1. Cooling system:
Comprehensive CFD calculations, thermodynamic calculations, the pump capacity, flow resistance, heat dissipation matching to achieve the best balance.
Adopt gear-driven water pump, high efficiency, high reliability, will not cause high temperature due to belt drive failure.
Double thermostat design improves the reliability of the cooling system.
Specially developed φ580 fan for wheat machine, optimizing the static pressure efficiency, consuming less power and better wind speed and volume.
Adopting one-piece radiator, the water tank and intercooler are arranged in parallel, which is convenient for cleaning and better cooling effect.
Referring to the market shading limit situation, simulate the heat balance under the ambient temperature of 45℃ to ensure that it can work normally when the radiator is partially shading.
2. Body, crankshaft, cylinder head, etc.
Adopting tractor structure to simulate the finite element calibration and design modification of the cylinder block, with a high safety coefficient, specialized for off-road applications.
High-strength cast iron cylinder block makes the crankshaft support body and crankcase become one, which is enough to cope with 50% over speed.
Specialized cylinder liner reticulation design better meets the needs of long-term high-load operation of agricultural equipment.
Laval engine adopts special structure piston, the top ring groove is set with heat-resistant alloy cast iron ring, and covered with wear-resistant plasma molybdenum layer.
Replaceable dry cylinder liner, low oil consumption in the long-term working life, and small performance decline after replacement.
3. Gas distribution and combustion technology:
Unique patented combustion technology, the engine’s thermal efficiency is higher, fuel economy is better, the whole vehicle use fuel consumption savings of 5%.
4-valve cylinder head structure, intake charge increased by more than 10%, casting airways, integrated intake manifold, thermostat housing in the cylinder head, more compact structure.
The engine torque reserve can be more than 40%, and the low-speed torque is sufficient to meet the use of tractors and other products.
The combustion system developed in cooperation with AVL, with soft diesel combustion, low engine vibration and low noise, is at the international advanced level.
4. Safety Protection:
The engine structure of national three products is fully adjusted, the supercharger is upwardly mounted, and the position of high temperature source is improved to keep away from the pile-up.
Supercharger, exhaust manifold high-temperature parts to increase protection, to avoid accumulation and straw and other direct fall.
