Abstract

The invention provides an intake gas heating device of a naturally aspirated engine, and belongs to the technical field of engines. The intake gas heating device comprises the engine, a water cavity, a temperature sensor, a water tank, a water pump and an electrometric valve, an engine gas inlet pipe between a gas filter and a throttle valve penetrates through the water cavity, the temperature sensor is arranged on an engine gas inlet pipe behind the gas filter, an engine exhaust pipe behind a silencer penetrates through the water tank, the two ends of a water cavity water inlet pipe are connected with the water cavity and the water tank respectively, the two ends of a water cavity water outlet pipe are connected with the water cavity and the water tank respectively, and the water pump and the electromagnetic valve are arranged on the water cavity water inlet pipe. In the intake gas heating device, the waste heat of the engine exhaust gas can be used for heating water in a water container, and therefore the engine intake gas can be heated. The intake gas heating device is reasonable in structure, simple in design and suitable for the design of engine exhaust gas waste heat utilization systems.

Description

Technical field [0001] The invention belongs to the technical field of automobile exhaust utilization, in particular, is a naturally aspirated engine air intake heating device that can use exhaust waste heat to add intake air. Background technique [0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (gasoline engines, etc.), external combustion engines (Stirling engines, steam engines, etc.), electric motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy. The engine is not only applicable to the power generating device, but also refers to the entire machine including the power device (such as: gasoline engine, aviation engine). The engine was first born in the United Kingdom, so the concept of the engine also originated from English. Its original meaning refers to the “mechanical device that produces power. Thermal efficiency refers to the ratio ...
