As an industry leader in the field of construction machinery power for nearly 20 years, Keluo Construction Machinery has always taken “technology-driven, quality-winning” as its core concept, and has won wide recognition from customers. In this article, we will focus on the engine body structure and key components, from the core components to auxiliary systems, and analyze the product's technical advantages and quality assurance.
1.Core Components
(1) High-strength mechanical transmission system
Cylinder and piston: Wear-resistant alloy cast iron cylinder liner, with lightweight forged aluminum piston, the surface of which is treated with nano-scale wear-resistant coating to adapt to extreme working temperature changes.
Crankshaft and connecting rod: Integral forged alloy steel crankshaft with high hardness and long service life.
(2) Precise fuel injection system
High-pressure oil pump: Maximum injection pressure reaches 2000 bar, supporting 5 times/cycle segmented injection, realizing fuel atomization particles ≤5μm, and improving combustion efficiency by 12%.
Electromagnetic injector: 0.1mm precision valve needle design, with intelligent control, can complete the injection response within 1ms, accurately matching the demand of full-load working conditions.
(3) High-efficiency Intake Booster System
The integrated turbocharger significantly improves the intake air density by optimizing the turbine blade angle and compressor runner design. The matching application of the intercooler further reduces the intake air temperature and enhances the oxygen content, resulting in a fuller combustion. The system automatically adjusts the boost pressure according to the working conditions, taking into account the low-speed torque output and high-speed power release, giving the engine a highly efficient response in the full speed range.
2. Auxiliary systems
(1) Thermal Management System
Intelligent cooling system realizes the precise regulation of engine working temperature through the cooperative work of electronic thermostat and variable flow water pump. The split water jacket design matches with the high-efficiency radiator to ensure that the key components are always in the best temperature window. Under extreme working conditions, the auxiliary cooling module automatically intervenes to ensure the thermal stability of the whole engine.
(2) Lubrication System
The oil filter and high-precision oil pump build up the lubrication guarantee system. The optimized design of the oil channel ensures continuous lubrication of the moving parts and effectively reduces friction loss. Intelligent oil pressure management system monitors the lubrication status in real time and automatically adjusts the oil pressure under low load conditions to realize the dual goals of energy saving and protection.
(3) Intake and exhaust system
The intake pipeline adopts a low resistance streamlined design with a large-capacity air filter to ensure the efficient supply of clean air. The exhaust system optimizes the back pressure and muffling structure to improve exhaust efficiency while reducing noise emissions. The integrated application of exhaust gas treatment device enables the whole machine to meet the global mainstream emission standards.
3.System synergy: Reconstructing power solutions
Our diesel engines for sale construct efficient power solutions for all scenarios through the deep synergy between core components and auxiliary systems:
Full working condition adaptation: from plateau mines to coastal ports, from cold zone construction to desert operation, the intelligent control system adjusts the power output in real time to ensure that the equipment is always in the best working condition.
Full Life Cycle Value: Through the breakthroughs in material science and durability design, the overhaul cycle of the whole machine is significantly extended and the maintenance cost is greatly reduced, creating a higher full life cycle value for customers.
Reliable in all dimensions: From component-level enhancement tests to endurance assessment of the whole machine, the company has built a whole-chain quality assurance system covering design, manufacturing and verification to ensure stable and reliable power output.
As the power heart of industrial equipment, diesel engine is redefining the power standard of construction machinery with systematic design thinking and in-depth integration of precision manufacturing and intelligent control, and the engines sold by Keluo Construction Machinery are creating sustainable value for global customers with excellent performance and reliable quality.
