Air cleaner in all terrain vehicle
An air cleaner is provided in an all terrain vehicle in order to improve the control performance for effecting optimal combustion in an engine by accurately measuring the temperature of air introduced into the engine. The air cleaner includes an air cleaner case disposed behind an engine, a throttle valve disposed between the engine and the air cleaner case, and connecting tube for connecting the air cleaner case and the throttle valve with each other. A temperature sensor is disposed in either a front or rear face of the air cleaner case. Optionally, the temperature sensor is disposed in the connecting tube.

11. The air cleaner in an all terrain vehicle according to claim 8 , wherein the temperature sensor is disposed in a grommet in the third mounting hole in the rear of said air cleaner case.
12. An air cleaner in an all terrain vehicle, comprising:
an air cleaner case disposed behind an engine;
a throttle valve disposed between said engine and said air cleaner case;
a connecting tube for connecting said air cleaner case and said throttle valve with each other; and
an exhaust pipe disposed on one side of a longitudinal center line (C) of said air cleaner;
wherein said temperature sensor is disposed on the other side of said longitudinal center line (C) of said air cleaner case,
wherein a temperature sensor is disposed in said connecting tube.
13. The air cleaner in an all terrain vehicle according to claim 12 , wherein a first mounting hole for fixing said connecting tube and a second mounting hole for fixing a snorkel duct which is introducing air into said air cleaner case are formed in a front of the air cleaner case, and a sensor mounting hole for directly fixing said temperature sensor is formed in a side of the connecting tube.
