Dongfeng LoongGine Engine parts Phase position sensor assembly 3611120-E1EC0

Engineered for exceptional accuracy, this phase position sensor assembly uses a Hall-effect sensing principle to detect the crankshaft or camshaft’s rotational position, delivering precise timing signals to the engine ECU. It features a high-sensitivity Hall element with a resolution of 0.1° crank angle, ensuring the ECU can accurately determine the engine’s top dead center (TDC) and valve timing—critical for optimizing fuel injection timing and ignition timing. Rigorous testing shows the sensor maintains a signal error margin of ≤0.5%, even at engine speeds up to 6000 rpm, ensuring stable performance during high-load operation (e.g., uphill driving, heavy cargo transport). The sensor’s signal response time is ≤10 μs, enabling real-time adjustments to fuel injection and ignition, which improves engine power output by 3-5% and reduces fuel consumption by 2-3% compared to low-precision sensors

The 3611120-E1EC0 phase sensor assembly is built to withstand the harsh mechanical stress and thermal conditions of heavy-duty engine operation. The sensor housing is made of high-temperature resistant PBT (polybutylene terephthalate) plastic reinforced with glass fiber, which maintains structural integrity at temperatures up to 150°C (common in engine bay environments) and resists deformation from vibration (up to 2000 Hz). The sensing element is encapsulated in a potting compound (epoxy resin) that provides shock resistance and prevents internal component damage from engine vibration. The sensor’s electrical connector is made of corrosion-resistant PA66 plastic with gold-plated pins, ensuring stable electrical contact even in environments with oil mist or moisture—extending the connector’s service life by 50% compared to standard tin-plated pins

To ensure consistent performance in diverse operating environments, this phase sensor assembly is designed with robust environmental protection features. It holds an IP6K9K ingress protection rating—providing complete protection against dust ingress and high-pressure, high-temperature water jets (up to 80°C, 80-100 bar)—making it suitable for engines operating in dusty construction sites or rainy/muddy off-road conditions. The sensor’s operating temperature range is -40°C to 150°C, enabling reliable performance in freezing winter climates (e.g., cold starts at -40°C) or hot summer conditions (e.g., engine bay temperatures exceeding 120°C). Additionally, it has a voltage input range of 9V-36V, compatible with Dongfeng LoongGine engines’ 12V or 24V electrical systems, and resists electromagnetic interference (EMI) in accordance with ISO 11452-2 standards—preventing signal disruption from nearby engine electrical components

Designed for user convenience, the 3611120-E1EC0 phase sensor assembly supports straightforward installation that aligns with Dongfeng LoongGine’s original engine layout. It features a standard M12 × 1.25 mounting thread (or custom thread based on engine model) that allows quick attachment to the engine’s timing cover or cylinder head using a standard wrench—no specialized tools required. The sensor’s electrical connector uses a push-to-lock design that ensures a secure, one-click connection to the engine’s wiring harness, reducing installation time by 40% compared to threaded connectors. For maintenance, the sensor requires no periodic calibration or cleaning—its sealed design prevents oil or debris from accumulating on the sensing surface. The part is laser-marked with the part number, manufacturing date, and technical specifications (e.g., voltage range, IP rating) for easy identification and traceability, simplifying inventory management for fleet workshops and ensuring compliance with Dongfeng LoongGine maintenance standards
