A method of controlling fuel delivery to an engine includes providing a fluid atomizer, a mechanically driven air compressor, a start up air source, and an air valve coupled between the mechanically driven air compressor and the start up air source, charging the start up air source, delivering compressed air from the start up air source to the fluid atomizer, providing an initial air/fluid mixture with the fluid atomizer, and operating the air valve to direct compressed air from the mechanically driven air compressor to the fluid atomizer.

An engine device includes an exhaust manifold provided on an exhaust side surface which is a first side surface of a cylinder head and a two-stage turbocharger that is driven by exhaust gas discharged from the exhaust manifold. The two-stage turbocharger includes a high-pressure turbocharger coupled to the exhaust manifold, and a low-pressure turbocharger coupled to the high-pressure turbocharger. The high-pressure turbocharger is arranged on a side of the exhaust manifold. The low-pressure turbocharger is arranged above the exhaust manifold. An exhaust gas outlet of the high-pressure turbocharger and an exhaust gas inlet of the low-pressure turbocharger are coupled with each other through a flexible high-pressure exhaust gas pipe.

A turbocharger flange includes a mounting face for attaching a turbocharger to a manifold, wherein the mounting face includes a guiding structure for guiding the flange to an operative position in relation to the manifold.

A turbocharged internal combustion engine system includes at least one high pressure turbocharger system mounted on-engine and at least one low pressure turbocharger system mounted off-engine. An intercooler can further be mounted off-engine with the low pressure turbocharger and an aftercooler can be mounted on-engine with the high pressure turbocharger.

A ship engine includes a first turbocharger, a first intercooler, a second turbocharger, and a second intercooler. The first turbocharger is arranged at one end of the ship engine with respect to a crank axis direction. The first intercooler and the second turbocharger are arranged in an end portion of the ship engine with respect to a device width direction. The first intercooler and the second turbocharger are arranged side by side in the crank axis direction. The second intercooler is arranged at the other end (at the side opposite to the side where the first turbocharger is arranged) of the ship engine with respect to the crank axis direction.

A straddle-type vehicle comprises a supercharging device which compresses intake-air to be sent to a combustion chamber of an engine; a catalyst provided in an exhaust passage through which an exhaust gas emitted from the engine flows; and a control section which controls the engine, wherein the control section performs an increase suppressing control for suppressing an increase in an exhaust gas temperature, in a case where the control section estimates that the exhaust gas temperature has exceeded an increase suppressing temperature set to be equal to or lower than a catalyst permissible temperature.

An exhaust-gas turbocharger (1) having a turbine housing (2), and having an exhaust manifold (3) connected to the turbine housing (2). At least one adapter ring (4, 5) is arranged between the turbine housing (2) and the exhaust manifold (3).
