The utility model relates to an intake manifold of engine, which comprises a pipe body (6), an air flue (3) and a cylinder mounting flange surface (5), wherein a throttle port (2) and a pressure stabilizing cavity (4) are arranged on the pipe body (6), and a sensor boss (1) is arranged on the top of the pipe body (6) above the throttle port (2) and the pressure stabilizing cavity (4). An air temperature pressure senor of the engine can be arranged on the sensor boss to collect two groups of data of air inlet temperature and pressure, and the data collected at the position has the highest precision and stability in any parts in the engine air intake system. An electronic control unit ECU receives information provided by the sensor for processing, and emits right orders to an executer according to the processing results to control the engine. The intake manifold can satisfy the increasingly stringent requirements of discharging law rules, and simultaneously improves the dynamic property of automobiles, the fuel
