An internal combustion engine including a fuel reformation unit that generates reformed fuel based on liquid fuel and higher in octane rating than the liquid fuel and introduces the generated reformed fuel to an output cylinder. The fuel reformation unit includes a first fuel reformer that includes a reciprocal mechanism where a piston reciprocates in a cylinder, a second fuel reformer that includes a reformation catalyst, and a reformed gas passage that connects the first and second fuel reformers together. First reformed gas discharged from the first fuel reformer is introduced to the second fuel reformer through the reformed gas passage.

An intake-air temperature controlling device is provided, which includes an engine body, an intake passage, a supercharger, a first passage, a second passage, an intake air flow rate adjuster, an intercooler, a pump, and a controller. The controller outputs a control signal to the pump so that coolant is supplied to the intercooler in a first operating range in which the intake air flow rate adjuster at least partially opens the first passage to supply intake air boosted by the supercharger to the engine body, and outputs a control signal to the pump so that the coolant is supplied to the intercooler also in a second operating range in which an engine load is below a given load, and the intake air flow rate adjuster opens the second passage and closes the first passage to supply the intake air to the engine body in a non-boosted state.

Systems, methods and apparatus for connection of a multi-stage turbocharger to a heat exchanger are disclosed. The multi-stage turbocharger includes at least first and second compressors with respective first and second outlets. An air intake system is provided that connects each of the first and second compressor outlets to a common inlet of a heat exchanger. The air intake system includes a flow transition segment connected to the first and second compressor outlets, a diffuser segment, and a flow delivery segment connected to the inlet of the heat exchanger.

A liquid drain valve assembly for a charge air cooler includes a valve housing configured to couple to the charge air cooler, the valve housing having a condensate inlet configured to receive condensate from the charge air cooler, and a condensate outlet, a valve mechanism slidingly disposed within the valve housing and configured to selectively close the condensate inlet and the condensate outlet to facilitate preventing charge air from leaking during condensate draining, and a diaphragm assembly disposed within the valve housing and configured to selectively engage the valve mechanism to selectively open the condensate inlet and the condensate outlet to drain condensate from the charge air cooler when the charge air cooler is in a boosted condition and isolated from the atmosphere.

The invention relates to a device for controlling the swirl of a fluid (2) flowing in a pipeline (1). The invention was based on the object of creating a device with which the adaptation of the swirl (2B) of a fluid (2) flowing in a pipeline (1), even in the case of constantly changing initial swirl (2B), to the desired flow conditions in the pipeline (1) is possible. Said object is achieved in that a swirl measuring device (4) and a swirl control device (6) are provided at predetermined positions of the pipeline (1), and the device has an evaluation and encoder unit (5), wherein, in the presence of differences between the measured actual swirl (2B) and the desired swirl, a corrective value can be determined by means of the evaluation and encoder unit (5), and the swirl control device (6) corresponds with the evaluation and encoder unit (5) and, by means of the swirl control device (6), the present swirl (2B) can be adapted to the predetermined desired swirl in accordance with the determined corrective value.
