Abstract

This invention discloses a vehicle engine operating environment simulation device, comprising a simulation chamber, an environmental simulation unit, and a condition monitoring system. A vehicle engine is installed in the simulation chamber. The environmental simulation unit provides different gas environments to the simulation chamber. An exhaust duct is connected to a supply duct that provides the gas environment to the simulation chamber. A pressure pump, cooling coil, heating wire, and humidifier are installed on the supply duct to provide a continuously circulating gas environment. The condition monitoring system includes an exhaust gas composition analyzer and a transmission mechanism. The exhaust gas composition analyzer is connected to the vehicle engine's exhaust pipe to monitor fuel efficiency. The transmission mechanism is connected to the vehicle engine's output shaft, and a torque and speed sensor is installed on the transmission mechanism to detect the engine's output power. This invention can simulate road conditions during vehicle operation, effectively monitoring the vehicle engine's operating status in various environments.
