EXHAUST STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2015/068504
Kind Code:
A1
Abstract:
An exhaust structure (3) is provided with an exhaust manifold (20), and a supercharger (30) having a turbine housing (50). The turbine housing (50) is provided with an inflow port (50a) interconnected with the exhaust manifold (20), an accommodating section (52) in which a space for accommodating turbine blades is formed, and an inflow section (53) in which an inflow channel (53a) leading from the inflow port (50a) through the accommodating space is formed. A sensor attachment part (53b) is formed in the inflow section (53), and a narrowing part (53c) is formed such that the width thereof in an alignment direction of cylinders (2) gradually decreases from the inflow port (50a) toward the sensor attachment part (53b). With this configuration, the precision of detecting the combustion state of the cylinders (2) can be increased.
