Abstract

Disclosed is a vehicle power generating apparatus which comprises: a generator; a rotary engine configured to serve as an engine for driving the generator, and installed in the vehicle in a posture where an output shaft thereof extends in an up-down direction; and an intake pipe and an exhaust pipe each connected to the rotary engine. The rotary engine comprises a pair of upper and lower side housings, and a rotor housing located between the upper and lower side housings. the rotor housing and the lower side housing are formed with an intake port and an exhaust port, respectively. The intake pipe is connected to a side surface of the rotor housing in such a manner as to be communicated with the intake port, and the exhaust pipe is connected to the lower side housing in such a manner as to be communicated with the exhaust port.

First claim

What is claimed is:

1. A vehicle power generating apparatus disposed in a position beneath a floor panel of a vehicle, comprising:
a generator;
a rotary engine configured to serve as an engine for driving the generator, and installed in the vehicle; and
an intake pipe and an exhaust pipe each connected to the rotary engine, wherein
the rotary engine comprises a pair of upper and lower side housings, and a rotor housing located between the upper and lower side housings, the rotor housing and the lower side housing being formed with an intake port and an exhaust port, respectively,
the intake pipe is connected to a side surface of the rotor housing in such a manner as to be communicated with the intake port, and
the exhaust pipe is connected to the lower side housing in such a manner as to be communicated with the exhaust port.

2. The vehicle power generating apparatus as defined in claim 1 , wherein
the exhaust pipe is connected to a side surface of the lower side housing, and
the exhaust port is formed to curve inside the lower side housing in such a manner as to be communicated with the exhaust pipe.

3. The vehicle power generating apparatus as defined in claim 2 , wherein
the generator and the rotary engine are arranged in adjacent relation to each other in a vehicle width direction,
the intake port is formed on a vehicle front side of the rotor housing of the rotary engine, and
the intake pipe is connected to the vehicle front side of the side surface of the rotor housing, and disposed to extend in the vehicle width direction, across a position on the vehicle front side of the generator.

4. The vehicle power generating apparatus as defined in claim 3 , wherein
the exhaust pipe comprises an exhaust gas purifying device disposed at a position on the vehicle front side of the rotary engine and beneath the intake pipe.

5. The vehicle power generating apparatus as defined in claim 4 , further comprising
a fuel tank configured to contain fuel for driving the rotary engine, and disposed at a position adjacent to the generator and on a side opposite to the rotary engine in the vehicle width direction, wherein
the exhaust pipe is configured to guide exhaust gas discharged from the engine and purified by the exhaust gas purifying device, in a vehicle rear direction via a position beneath the generator.

6. The vehicle power generating apparatus as defined in claim 1 , wherein
the generator and the rotary engine are arranged in adjacent relation to each other in a vehicle width direction,
the intake port is formed on a vehicle front side of the rotor housing of the rotary engine, and
the intake pipe is connected to the vehicle front side of the side surface of the rotor housing, and disposed to extend in the vehicle width direction, across a position on the vehicle front side of the generator.

7. The vehicle power generating apparatus as defined in claim 6 , wherein
the exhaust pipe comprises an exhaust gas purifying device disposed at a position on the vehicle front side of the rotary engine and beneath the intake pipe.

8. The vehicle power generating apparatus as defined in claim 6 , further comprising
a fuel tank configured to contain fuel for driving the rotary engine, and disposed at a position adjacent to the generator and on a side opposite to the rotary engine in the vehicle width direction, wherein
the exhaust pipe is configured to guide exhaust gas discharged from the engine and purified by the exhaust gas purifying device, in a vehicle rear direction via a position beneath the generator.
