A power transmission system transmits power from an internal combustion engine to a first and a second auxiliary device through an endless transmitting member. Prior to issuing of an engine start request, the first auxiliary device is actuated to move a tensioner pulley to a given position to increase the degree of tension of the endless transmitting member. The actuation of the first auxiliary device as an engine starter upon the issuing of the engine start request, therefore, enables a drive shaft of the engine to be rotated immediately within a required time to crank the engine. This achieves a quick start of the engine and results in a decrease in amount of time between the issuing of the engine start request and the actual start of the engine.

Structure of power transmission apparatus

A particulate concentration detector including a detection mechanism having a light emission unit and light reception unit. The particulate concentration detector detects the concentration of particulates suspended in a liquid from the light amount detected by the detection mechanism. The detection mechanism includes a first light guide, a second light guide, a liquid chamber, and a third light guide. The first light guide is arranged at a location facing toward a light emission surface of the light emission unit. The second light guide is arranged at a location facing toward a light reception surface of the light reception unit. The liquid chamber is formed between the first light guide and second light guide and allows the liquid to flow therein. The third light guide is arranged in an oscillatable manner in the liquid chamber so as to face toward the first light guide and the second light guide.

Particle concentration detecting device

A liquid fuel property detection apparatus includes a fuel passage, a light emitting device for emitting a light including a plurality of predetermined wavelengths toward the fuel in the passage, a light receiving device for receiving the light passing through the fuel, and a calculation unit for calculating the concentration of at least one of aroma, paraffin and olefin, which are hydrocarbon component components contained in the fuel. The calculation unit calculates the concentration of a specific component, which is one of aroma, paraffin and olefin, based on the reference transmittance of light in the specific component and the actual transmittance calculated from the amount of light emitted by the light emitting device and the amount of light received by the light receiving device with respect to each wavelength of the light.
