Product Overview: Denso Automotive Fuel Injector 295700-1190
The Denso Automotive Fuel Injector, part number 295700-1190, represents a pinnacle of precision engineering in modern diesel engine fuel systems. Designed to meet the stringent requirements of contemporary emissions standards and performance demands, this injector plays a critical role in ensuring optimal combustion, power output, and fuel efficiency. As a key component in advanced common-rail systems, it delivers exceptional reliability and control, making it an essential upgrade or replacement part for a range of commercial vehicles. This overview details its structural features, technical advantages, application scenarios, OEM compatibility, and essential maintenance guidelines to maximize its operational lifespan and performance.
1. Structural Features and Technical Advantages
The Denso 295700-1190 fuel injector incorporates several sophisticated structural features that collectively contribute to its superior performance. A key design aspect likely involves the use of high-precision materials for its core components, such as the nozzle needle and valve seat, ensuring long-term durability and resistance to wear and corrosion under high-pressure conditions. The injector's solenoid is engineered for rapid magnetic response, enabling exceptionally fast opening and closing times. This is complemented by an integrated filtration system, a critical feature highlighted in advanced injector designs for preventing particulate contaminants from entering the delicate internal passages, thereby safeguarding the injector's operational integrity.
The technical advantages derived from this refined design are multifaceted. Firstly, the injector provides outstanding fuel atomization, creating a fine, homogeneous spray pattern. This is achieved through a meticulously engineered multi-orifice nozzle that ensures optimal droplet size and distribution. Superior atomization leads directly to more efficient and complete combustion within the engine cylinder. This efficiency translates into tangible benefits, including enhanced fuel economy, as more energy is extracted from each unit of fuel, and a significant reduction in harmful emissions, as the complete combustion process minimizes the output of unburned hydrocarbons and soot. Furthermore, the fast response characteristics of the electromagnetic circuit allow for highly precise fuel delivery across a wide range of engine operating conditions, from idle to full load. This precision contributes to improved throttle response, smoother engine operation, and stable performance. Specifically, for performance-oriented applications, this injector is designed to operate at higher injection pressures, which contributes to greater power output—reportedly up to a 10% increase in some configurations.
2. Application Scenarios and Primary Application Fields
The Denso 295700-1190 fuel injector is specifically engineered for heavy-duty applications in the commercial vehicle sector. Its primary application is in Hino 300 Series trucks equipped with the N04C engine platform. This injector is a critical component designed to function within modern high-pressure common-rail fuel systems, which are renowned for their ability to precisely control fuel injection timing and quantity. Its role is to deliver a precisely metered amount of fuel directly into the combustion chamber at the exact moment commanded by the engine's Electronic Control Unit (ECU). The reliable performance of this injector is essential for achieving the engine's designed power output, meeting stringent Euro 6 emissions standards, and ensuring overall drivability and fuel efficiency. Therefore, its main field of use is the commercial transportation industry, serving as an essential part of the engine's fuel system in a specific range of Hino trucks to ensure optimal combustion, drivability, and regulatory compliance.
3. OEM Cross-Reference Numbers
Identifying exact OEM cross-reference numbers is crucial for ensuring compatibility and finding equivalent parts. For the Denso fuel injector 295700-1190, the available search results indicate at least one direct alternate part number.
The primary cross-reference identified is:
23670-E9301
This number represents an alternative part number for the same or a highly compatible injector assembly used in Hino 300 Series N04C engines. To ensure accuracy and a complete list of all possible equivalents from other manufacturers, it is strongly recommended to consult verified professional resources. Technicians and parts specialists should refer to official Denso application catalogs or comprehensive professional automotive databases for the most up-to-date and exhaustive cross-reference information.
4. Daily Preventive Maintenance Recommendations
Proper and proactive maintenance is paramount for maximizing the service life and ensuring the consistent performance of the Denso 295700-1190 fuel injector. Adherence to a disciplined maintenance schedule can prevent common issues such as clogging, poor atomization, and injector failure.
The most critical maintenance practice is the consistent use of high-quality fuel and the strict adherence to fuel filter replacement intervals. Clean fuel is paramount; even minor contaminants can gradually clog the injector's fine filter and nozzle holes, leading to degraded spray patterns and impaired engine performance. It is essential to use fuel from reputable sources and to replace the vehicle's fuel filter at the intervals specified by the vehicle manufacturer to prevent debris from reaching the injectors.
Periodic inspection and professional cleaning of the injectors are also highly recommended. Over time, even with clean fuel, carbon deposits can form on the injector tips. These deposits should be cleaned using specialized fuel system cleaning additives or, for more thorough maintenance, via professional ultrasonic cleaning equipment. This process helps restore the injector's flow rate and spray pattern to their original specifications. Furthermore, it is vital to maintain the integrity of the entire fuel system. This includes ensuring that the injector's electrical connector is securely seated and that the return hose (if applicable) is properly connected and not blocked, as this is designed to channel away excess fuel and maintain system balance. Regular checks of the air filter are also important, as a clogged air filter can disrupt the air-fuel mixture, indirectly affecting combustion efficiency and potentially leading to carbon buildup on injectors.
