An internal combustion engine comprises an exhaust purification catalyst (20) and an air-fuel ratio sensor (41) arranged at a downstream side of the exhaust purification catalyst, stops or decreases a feed of fuel as fuel cut control, and controls an air-f...

An object of the invention is to provide an EGR cooler which enhances a cooling performance by increasing a ratio of the volume of a core portion which performs a heat exchange and enhances a pressure resistance strength. There is provided an EGR cooler ha...

The objective of the present invention is to prevent an increase in the amount of oxygen stored in a catalyst due to a fuel cut by performing a rich spike, even when the fuel is again supplied after a fuel cut in some of the cylinders. When a prescribed fu...

A reducing agent supply apparatus that can reduce the state of large deviation of the pressure within a reducing agent supply passage from a target pressure and an exhaust gas purification apparatus including such a reducing agent supply apparatus are prov...

An air-fuel ratio control apparatus for an internal combustion engine according to an embodiment of the invention (the present control apparatus) sets a target air-fuel ratio to a target rich air-fuel ratio when it is determined on the basis of the output ...

An object of this invention is to accurately control an exhaust air-fuel ratio, even when a WGV (waste gate valve) is operating. An ECU 60 is equipped with a turbine passing path constant At that corresponds to a time required for exhaust gas to flow to an...

This invention relates to an internal combustion engine and a control device for the internal combustion engine and has an object to provide an internal combustion engine and a control device therefor that can suppress occurrence of knocking if an EGR rate...

The line element (1) has a housing (3) i.e. annular sleeve, radially surrounding a fluid line (2) in a fluid-tight manner. An annular space (4) is designed between the fluid line and the housing. The annular space is partially filled with compressible medi...
