摘要： The invention presents a multi-engine synchronous detection and analysis system. It includes modules for inputting engine information, matching engine models, identifying fault locations, and processing faults. After maintenance, the system analyzes engine operation, stores data, and generates maintenance reports summarizing fault causes and locations. It optimizes the matching module based on regulatory outcomes. Using three-dimensional modeling and operational mechanisms, the invention evaluates engine state and predicts its lifespan. It summarizes components prone to failure across different engine types using historical and maintenance data.

摘要： A system and methods for a turbo-boost control system are disclosed for providing a driver of a vehicle with greater control over vehicle performance. The turbo-boost control system instructs an electronic control unit of the vehicle to increase the manifold pressure to a higher level before releasing the pressure through a waste gate so as to provide a greater power output of the engine. The turbo-boost control system includes a control module, a wiring harness, and a signal adjuster. The wiring harness couples the control module with a turbo inlet pressure sensor, a manifold absolute pressure sensor, and an electronic control unit of the vehicle. The control module sends signals to the electronic control unit based on input readings from the turbo inlet pressure sensor and the manifold absolute pressure sensor. The signal adjuster includes a rheostat that enables manual adjustment of the power output of the engine.

摘要： A High Pressure Thermal Fluid Brake and Engine Energy Recovery System is provided, comprising a plurality of interconnected energy collection system and energy storage system, and a control unit connected with the energy collection system and the energy storage system. The control unit is connected with the vehicle controller to at least read and collect acceleration pedal position information, brake pedal position information, vehicle travel parameters and cooling system parameters of the vehicle. The energy collection system recovers vehicle kinetic energy, engine mechanical energy and engine thermal energy and stores the recovered energy in the energy storage system. The control unit controls the energy recovery and release of the energy collection system and the energy storage system according to the vehicle information read and collected. This system can effectively recover vehicle braking energy, engine idle energy and engine heat energy and reuse, reduce the energy waste of motor vehicle system to achieve the purpose of energy saving, fuel saving and emission reduction.

摘要： Systems and methods provide for cleaning the air intake valves and surrounding areas of an engine. A gravity-fed cleaning-fluid dispenser may feed cleaning fluid into a hose through a metered device that meters a rate at which the cleaning fluid flows into the hose. A second fluid meter connected to a distal end of the hose further meters the rate at which a mixture of the cleaning fluid and air from is dispersed into the running GDI engine. Cleaning fluid may be distributed to the engine at a gradually decreasing rate as a volume of cleaning fluid in the dispenser decreases as the service progresses.
