Abstract

A V-type multi-cylinder engine including a pair of banks, includes: an intake member forming an intake passage through which air is guided from outside; a pair of throttles each configured to regulate an amount of the air sucked into each of the pair of banks through the intake passage; and one single temperature sensor configured to detect a temperature of the air in the intake passage. The intake member includes a pair of openings downstream in a flowing direction of the air. Each the pair of throttles is connected to each of the pair of openings. The temperature sensor is disposed between the pair of openings.

Claims (37)

1. A V-type multi-cylinder engine including a pair of banks, comprising:

an intake member forming an intake passage through which air is guided from outside;

a pair of throttles each configured to regulate an amount of the air sucked into each of the pair of banks through the intake passage;

one single temperature sensor configured to detect a temperature of the air in the intake passage; and

a recirculation member configured to recirculate blow-by gas from the engine into the intake passage, wherein

the intake member includes:

a pair of openings downstream of the temperature sensor in a flowing direction of the air; and

a pair of cylindrical members each extending from each of the pair of openings in the flowing direction of the air, wherein

each of the pair of throttles is connected to each of the pair of cylindrical members, wherein

the temperature sensor is disposed between the pair of openings, wherein

the recirculation member is connected to the pair of cylindrical members from between the pair of cylindrical members.

2. The engine according to claim 1 , wherein

a distance from one of the pair of openings to the temperature sensor is equal to a distance from the other of the pair of openings to the temperature sensor.

3. The engine according to claim 1 , wherein

the temperature sensor includes: a detecting member configured to detect the temperature of the air; and a supporting member configured to support the detecting member in the intake passage, wherein

the supporting member is fixed to the intake member from outside between the pair of cylindrical members, wherein

the temperature sensor penetrates the intake member.

4. The engine according to claim 1 , wherein

the intake member is configured to be dividable.

5. An outboard motor, comprising:

the engine according to claim 1 ; and

a propeller driven by the engine to rotate.

6. The outboard motor according to claim 5 , wherein

the outboard motor is mounted on a stern of a boat, wherein

the pair of openings are disposed further on a bow side of the boat than the pair of throttles with the outboard motor tilted down, wherein

the temperature sensor includes: a detecting member configured to detect the temperature of the air; and a supporting member configured to support the detecting member in the intake passage, wherein

the supporting member is fixed to the intake member from outside in a direction from a stern side of the boat to the bow side with the outboard motor tilted down, wherein

the temperature sensor penetrates the intake member, wherein

the detecting member extends horizontally from the supporting member in the direction from the stern side to the bow side with the outboard motor tilted down.

7. The outboard motor according to claim 5 , wherein

the outboard motor is mounted on a stern of a boat, wherein

the pair of openings are disposed further on a bow side of the boat than the pair of throttles with the outboard motor tilted down, wherein

the temperature sensor includes: a detecting member configured to detect the temperature of the air; and a supporting member configured to support the detecting member in the intake passage, wherein

the detecting member extends upward from the supporting member with the outboard motor tilted up.

8. A boat, comprising:

the outboard motor according to claim 5 ; and

a hull mounted with the outboard motor.
