Dongfeng LoongGine Engine parts electronic control unit assembly 3610010-E1EC0

Engineered for exceptional control accuracy, this ECU assembly features a 32-bit dual-core microprocessor (operating frequency ≥100 MHz) that processes real-time engine data at a sampling rate of 1500 times per second. It precisely regulates critical engine parameters: fuel injection timing (adjustable in 0.1° crank angle increments), injection duration (control accuracy ±0.05 ms), and ignition timing (for gasoline engines) or EGR flow rate (for diesel engines). Rigorous testing shows the ECU optimizes the air-fuel ratio to within ±0.2 of the ideal stoichiometric value, improving combustion efficiency by 4-6%. This translates to a 3-5% boost in maximum engine power, a 2-4% reduction in fuel consumption under heavy loads (e.g., long-haul transportation), and compliance with China VI emission standards by precisely controlling exhaust gas recirculation and aftertreatment systems

Built to withstand the harsh operating conditions of heavy-duty engine bays, the 3610010-E1EC0 ECU assembly features a robust aluminum alloy housing (with anodized surface treatment) that provides excellent thermal conductivity and impact resistance. The housing meets IP6K9K ingress protection standards, ensuring complete protection against dust ingress and high-pressure, high-temperature water jets (up to 80°C, 100 bar)—critical for engines operating in dusty construction sites or rainy off-road environments. The ECU’s operating temperature range is -40°C to 90°C, enabling stable performance in freezing winter cold starts or hot summer engine bay conditions (where temperatures often exceed 75°C). It also resists electromagnetic interference (EMI) in accordance with ISO 11452-4, preventing signal disruption from nearby electrical components like alternators or turbocharger controllers

To ensure engine safety and long-term reliability, the ECU integrates comprehensive protection mechanisms and advanced diagnostic functions. It includes overvoltage protection (up to 36V) and reverse polarity protection to shield internal circuits from electrical surges or incorrect wiring during maintenance. A thermal shutdown function activates if the ECU’s internal temperature exceeds 105°C, preventing component damage from overheating. The ECU also features a built-in OBD-II compliant diagnostic system that continuously monitors 50+ engine parameters (sensor signals, actuator performance, emission levels). When anomalies are detected (e.g., a faulty oxygen sensor or clogged fuel injector), it stores detailed fault codes (following SAE J1939 protocol) and triggers a warning light on the vehicle dashboard. Mechanics can read these codes via standard OBD scanners or Dongfeng’s proprietary diagnostic tool, reducing troubleshooting time by 50% compared to non-diagnostic ECUs

Designed for user convenience, the 3610010-E1EC0 ECU assembly supports quick, plug-and-play installation. It mounts to the engine’s dedicated ECU bracket via pre-drilled holes that align with Dongfeng LoongGine’s original mounting points, requiring only basic hand tools (socket wrench, screwdriver) for attachment. The electrical connector uses a locking lever design with a rubber O-ring seal, ensuring a secure, waterproof connection to the engine’s wiring harness—installation can be completed in 20-30 minutes by a single technician. The ECU requires no periodic maintenance; its solid-state design has no moving parts, and the aluminum housing dissipates heat passively without needing fans or coolants. The housing is laser-marked with the part number, voltage rating (12V/24V), and calibration version for easy identification, simplifying inventory management for fleet workshops and ensuring the correct ECU is used for specific LoongGine engine models
