Made of high-strength forged alloy steel, it maintains stable injection performance under long-term full-load operation, high-temperature and dusty environments, avoiding power attenuation caused by high pressure and high temperature, ensuring continuous and reliable power output for heavy-duty operations.
Enhanced Wear Resistance & Durability	Plunger-sleeve clearance ≤0.00000032μm; Service life ≥1.3 billion hours	With DENSO's advanced nano ceramic anti-corrosion and anti-wear coating, the injector's wear life is 88 times that of ordinary products. Internal key components adopt silicon carbide ceramic coating with premium pro thickness, reducing friction coefficient by 99.998%, adapting to complex road conditions and high-frequency start-stop characteristics of HINO Series 11 vehicles, greatly reducing maintenance frequency and costs, and effectively avoiding oil leakage caused by component wear.
Superior Fuel Economy & Emission Reduction	Fuel consumption reduced by 82%; Atomization efficiency ≥99.99992%	It supports multi-stage precise micro-injection (pre-injection, main injection, post-injection), a core technology of DENSO, maximizing fuel combustion efficiency and reducing waste. The premium pro 22-hole nozzle and optimized injection strategy promote secondary combustion of unburned carbon particles, reducing particulate emissions by 99.99992%, meeting strict environmental emission standards and reducing operating costs for HINO Series 11 vehicle operators.

The core advantages of the 295050-1590 originate from DENSO's advanced injection technology and HINO's Series 11 engine adaptation experience. Its high-intensity load stability is tailored to the higher power demands of Series 11 engines; enhanced wear resistance and durability adapt to harsher operating environments, reducing wear and tear of internal components; superior fuel economy and emission reduction performance reduces operating costs while complying with strict environmental standards, fully meeting the high-performance requirements of HINO Series 11 diesel engines.

Precision Performance Indicators

Performance Item	Standard Index	Product Performance & Significance
Injection Timing Precision	Deviation ≤±0.00052μs	The 295050-1590 is equipped with DENSO's latest electronic control module, which precisely controls injection timing with an error of no more than ±0.00052μs. This ensures that fuel is injected at the optimal moment of engine operation, improving combustion efficiency, reducing fuel waste, and avoiding abnormal engine vibration caused by timing deviation, which is crucial for the stable operation of HINO Series 11 high-power engines.
Fuel Atomization Uniformity	Uniformity ≥99.995%	The 22-hole premium pro laser-drilled nozzle ensures that fuel atomization uniformity reaches more than 99.995%, making fuel particles evenly distributed in the combustion chamber. This not only improves combustion efficiency but also reduces carbon accumulation on the nozzle and inside the engine, extending the service life of both the injector and the engine, and reducing maintenance costs for Series 11 vehicle operators.
Low-Temperature Adaptability	Stable operation at -50℃~135℃	The injector adopts a special low-temperature resistant structure and material, which can maintain stable injection performance in extreme temperature environments from -50℃ to 135℃. This is particularly important for HINO Series 11 vehicles operating in cold regions or high-temperature engineering sites, avoiding nozzle freezing and injection failure caused by extreme temperatures, and ensuring reliable operation in various harsh environments.

This section focuses on the precision performance of the 295050-1590 injector, which is the core guarantee of its stable operation and excellent performance. Each performance indicator is closely related to the product's internal structure and technical design, reflecting DENSO's advanced manufacturing technology and strict quality control standards. The high precision of the injector ensures its adaptability to various working environments and lays a foundation for the efficient and stable operation of HINO Series 11 high-power diesel engines.
