For complete technical specifications and ordering details, please refer to the official Sinotruk Catalog, which provides comprehensive information on all available variants and compatible truck models for the Engine Monitoring system.
The Engine Monitoring kit includes sensors for speed, temperature, pressure, and air management, along with the necessary high-strength fasteners and sealing washers. Every component is manufactured to OEM specifications, guaranteeing a perfect fit and reliable performance under extreme conditions.
This Engine Monitoring solution is designed for long-term durability, using corrosion-resistant materials and precision engineering. It ensures that your truck’s ECU receives accurate data for optimal fuel injection, timing, and emission control, directly impacting fuel economy and engine longevity.
The Speed Sensor monitors crankshaft or camshaft rotation, providing the ECU with essential data for ignition timing and fuel injection. It uses a Hall-effect element for non-contact measurement, ensuring high reliability and resistance to dirt and oil.
This sensor is crucial for the Engine Monitoring system, enabling accurate speed detection even at low rpm. Its robust housing protects against vibration and thermal stress, and the connector is sealed against moisture ingress.
This high-strength M6 flange bolt is used to secure various sensors and mounting brackets in the Engine Monitoring system. With a grade of 10.9 and a zinc-nickel coating, it offers excellent corrosion resistance and clamping force.
The integrated flange eliminates the need for a separate washer, simplifying installation and ensuring even load distribution. Its precise thread geometry ensures a secure fit in the engine block mounting holes.
This longer M6 flange bolt is used for deeper mounting points, such as securing the speed sensor or other components. Manufactured from grade 10.9 alloy steel with a corrosion-resistant coating, it provides reliable fastening under high vibration.
Its 16mm length accommodates thicker brackets, and the flanged head provides a large bearing surface to prevent loosening. This bolt is an essential part of the Engine Monitoring assembly.
This sealing washer is used with threaded connections to prevent fluid leaks. It consists of a steel core and an FPM rubber outer layer, providing excellent resistance to oil, coolant, and high temperatures up to 150°C.
In the Engine Monitoring system, it is typically used with coolant temperature sensors or other fluid-carrying components to ensure a leak-proof seal, maintaining system integrity.
The Coolant Temperature Sensor measures the engine coolant temperature, providing the ECU with data for cold-start enrichment, fan control, and emission strategies. It uses a thermistor with a negative temperature coefficient for accurate readings.
This sensor is a vital part of the Engine Monitoring system, ensuring the engine warms up quickly and operates within the optimal temperature range. Its threaded body allows direct mounting into the coolant jacket.
This larger composite sealing washer is used for high-pressure connections, such as those for oil or fuel pressure sensors. Its steel core provides structural strength, while the FPM rubber seal ensures leak-free operation.
With a diameter of 18.7mm inner and 26.0mm outer, it fits larger fittings and is designed to withstand the higher pressures found in lubrication and fuel systems.
The Oil Pressure Sensor monitors engine oil pressure, providing a critical safety signal to the ECU and dashboard gauge. It uses a piezoresistive element that converts pressure into a variable voltage signal, indicating oil pressure status.
In the Engine Monitoring system, this sensor helps prevent engine damage by alerting the driver to low oil pressure. Its robust construction ensures reliable readings even at high temperatures and vibration levels.
This sensor measures the fuel pressure in the common rail system, enabling precise fuel delivery control. It is designed for high-pressure applications, typically up to 2000 bar, and provides a linear output signal to the ECU.
Proper fuel pressure monitoring is essential for the Engine Monitoring system to maintain optimal combustion and reduce emissions. The sensor is built with a stainless steel diaphragm for durability against fuel corrosion.
This combined sensor measures both the temperature and pressure of the intake air, allowing the ECU to calculate air density for accurate fuel metering. It is essential for turbocharged engines to optimize boost control and fuel economy.
The sensor integrates two sensing elements in a single housing, saving space and reducing wiring complexity. Its fast response time ensures that the Engine Monitoring system reacts quickly to changes in operating conditions.
This wave spring washer is used to maintain tension on fasteners, preventing loosening due to vibration. Its wavy profile provides a spring effect that compensates for thermal expansion and shock loads.
In the Engine Monitoring system, it is often used with sensor mounting screws to ensure consistent clamping force, enhancing the reliability of the electrical connections.
This standard hexagon head bolt is used for general fastening applications within the Engine Monitoring system. It is made of grade 8.8 steel with a zinc plating, offering good strength and corrosion resistance for light-duty mounting.
Its hex head allows for easy installation with standard tools, and its compact size makes it suitable for smaller sensor brackets and covers.
The Engine Monitoring kit includes every sensor needed to track critical parameters—speed, temperature, oil and fuel pressure, and intake air conditions. This comprehensive coverage enables proactive maintenance and prevents unexpected breakdowns.
All bolts, washers, and sealing elements in this Engine Monitoring kit are manufactured to the highest standards, ensuring that sensors remain firmly attached and sealed against the elements. This reduces the risk of sensor failure due to vibration or leaks.
Every component of the Engine Monitoring system is built from corrosion-resistant alloys, high-temperature rubbers, and robust plastics. This ensures reliable operation in extreme temperatures, high humidity, and exposure to oils and fuels.
The Engine Monitoring kit is manufactured to the exact OEM specifications, guaranteeing a perfect fit for the Sitrak C7H. Each sensor and fastener is identical to the original equipment, simplifying replacement and ensuring no modification is required.
