Abstract

An air heating device for a motor vehicle engine, which belongs to the field of engine heating, and is characterized in that an engine exhaust pipe (9) is set inside the air heating pipe (2), and the air heating pipe (2) communicates with the air filter (1) , the air heating pipe (2) is fixedly installed with a heating air resistance wire (4), the engine (8) communicates with the air filter (1) through the intake pipe (7), and the engine radiator (6) passes through the ventilation pipe ( 3) It communicates with the air filter (1), and radiator windshields (5) are installed on both sides of the engine radiator (6). The heating device absorbs the heat discharged from the exhaust pipe and the heat emitted by the engine radiator, and connects the air intake pipe with the engine intake pipe to increase the temperature of the air sucked by the engine intake pipe, so that the engine reaches the normal starting temperature.

Description

Motor vehicle engine air heating device

technical field

The utility model relates to the field of motor vehicle engine heating, in particular to a motor vehicle engine air heating device.

Background technique

Existing vehicle engines, because the winter temperature drops below zero, the engine power decreases and the oil consumption increases. When the temperature is too low, it is difficult to start the engine, and the engine warm-up time is too long. When the engine temperature does not rise to normal temperature, the radiator remains Let out the heat.

Contents of the invention

The technical problem to be solved by the utility model is to provide an engine air heating device which can directly heat the air in the engine.

The technical problem to be solved by the utility model is realized through the following proposals:

An air heating device for a motor vehicle engine, mainly composed of an air heating tube 2, a heating air resistance wire 4, an air filter 1, and a radiator windshield 5, and is characterized in that the air heating tube 2 is equipped with an engine exhaust Pipe 9, the air heating pipe 2 communicates with the air filter 1, the air heating pipe 2 is fixedly installed with a heating air resistance wire 4, the engine 8 communicates with the air filter 1 through the intake pipe 7, and the engine radiator 6 passes through The ventilation pipe 3 is in communication with the air filter 1 , and radiator windshields 5 are installed on both sides of the engine radiator 6 .

Compared with the prior art, the utility model has the following beneficial effects:

The heating device absorbs the heat discharged from the exhaust pipe and the heat emitted by the engine radiator, and connects the air intake pipe with the engine intake pipe to increase the temperature of the air sucked by the engine intake pipe, so that the engine reaches the normal starting temperature and can be opened and closed. The engine radiator windshield makes it easier to control the temperature of the engine.

Detailed ways

An air heating device for a motor vehicle engine, characterized in that the air heating pipe 2 is set with an engine exhaust pipe 9, the air heating pipe 2 is connected to the air filter 1, and the air heating pipe 2 is fixedly installed with a heating air resistance wire 4. Use the vehicle battery to heat the air resistance wire 4 when warming up before the engine starts. Engine 8 communicates with air filter 1 through intake pipe 7, and engine radiator 6 communicates with air filter 1 through ventilation pipe 3. Radiator windshield 5 is installed on both sides of engine radiator 6.

The engine radiator windshield 5 that can be opened and closed makes the temperature of the engine easier to control. The windshield 5 mounted on both sides of the engine radiator 6 can be designed as a straight plate, a roller shutter or a strip type, and the windshield 5 can be all Open, can be fully enclosed, use multi-speed control switch to control the air flow, when the engine is warming up, the engine speed is low, the air intake is small, the windshields on both sides of the engine radiator can be closed, and the temperature of the exhaust pipe 9 rises rapidly , use the exhaust pipe 9 to heat the air, which can meet the air volume required for the low-speed operation of the engine. When the temperature is too low when the vehicle is running normally, the radiator 5 can be properly opened. When the engine temperature is too high, the two sides can be turned on. The windshield 5 is fully opened, which does not affect the normal heat dissipation of the engine radiator.

When the single-cylinder engine uses the water tank to directly dissipate heat in winter, the water tank is equipped with a ventilation pipe connected to the engine air filter 1, and a valve is installed at the connection between the ventilation pipe and the air filter 1, which can be closed and opened to control the ventilation volume.

Claims (1)

1, a kind of motor vehicle engine air heating device, mainly is made up of air heating tube (2), heating air resistance wire (4), air filter (1), radiator windshield (5), is characterized in that An engine exhaust pipe (9) is set inside the air heating pipe (2), the air heating pipe (2) communicates with the air filter (1), and the air heating pipe (2) is fixedly installed with a heating air resistance wire (4 ), the engine (8) communicates with the air filter (1) through the intake pipe (7), the engine radiator (6) communicates with the air filter (1) through the ventilation pipe (3), and the engine radiator ( 6) Radiator windshields (5) are installed on both sides.
