An intercooler may include an air-outlet tank, a condensate collector for collecting condensate separated off the intercooler, and a condensate line connected to the condensate collector via an entrance and that opens out into the air-outlet tank via an exit. There may be a pressure difference between the entrance and the exit of the condensate line during operation of the intercooler, and said pressure difference may allow differential-pressure-induced discharge of condensate from the condensate collector via the condensate line.

To balance a low-temperature scavenging effect and a high-temperature scavenging effect. A scavenging system applicable to a leading-air type two-stroke air-cooled engine has a low-temperature scavenging passage and a high-temperature scavenging passage. The low-temperature scavenging passage has first and second passages and includes scavenging ports at upper end parts thereof. The high-temperature scavenging passage has first and second passages and includes scavenging ports at upper end parts thereof. An air is filled through a piston groove into the passages. The low-temperature scavenging passage has a relatively small capacity. The high-temperature scavenging passage has a relatively large capacity.

An intercooler may include a condensate collector configured to collect condensate precipitated in the intercooler. The condensate collector may be separate from the intercooler and disposed below the intercooler. The condensate collector may include at least one expansion chamber, the at least one expansion chamber arranged above an inlet and an outlet of the condensate collector during operation of the intercooler.

In an internal combustion engine provided with a combustion chamber defined by an inner circumferential surface of a cylinder, an end surface of a cylinder head facing the cylinder, a crown surface of a piston, an inner surface of an intake valve, and an inner surface of an exhaust valve, for the purpose of improving the anti-knocking performance of the engine, the inner circumferential surface of the cylinder, the end surface of the cylinder head, the crown surface of the piston, the inner surface of the intake valve and the inner surface of the exhaust valve include a mirror surface region formed as a mirror surface having an arithmetic average roughness of 0.3 m or less, and a rough surface region formed as a rough surface having an arithmetic average roughness of 0.3 m or more.

A charge-air cooling device for a fresh air system of an internal combustion engine may include a housing which contains a charge-air duct and a heat exchanger having an internal coolant path and an external charge-air path. The housing may have a mounting opening, through which the heat exchanger is pushed into the housing in a longitudinal direction of the heat exchanger such that, in a pushed-in state, the charge-air duct leads through the charge-air path. The housing may include at least one wall in a receiving region which receives the heat exchanger. The wall may be elastic and, by the heat exchanger being pushed into the receiving region, the wall may be transferred from a relaxed state when the heat exchanger has not been pushed into the receiving region, into a stressed state when the heat exchanger has been pushed into the receiving region.

The invention relates to an air duct arrangement (100), in particular a charge air duct for a turbocharged engine, having an inlet air duct (60), a cooler (10) with an inlet (37) and an outlet (38), the cooler (10) having at least one air flow path portion (12, 14, 16, 18) extending between the inlet (37) and the outlet (38) along a longitudinal elongation (66) of the cooler (10) and having an outlet aperture (13, 15, 17, 19), and at least two runners (22, 24, 26, 28) of an air intake manifold (20) of an engine (40). The cooler (10) is arranged between the inlet air duct (60) and the runners (22, 24, 26, 28). Each runner (22, 24, 26, 28) has an inlet aperture (23, 25. 27, 29) and the outlet (38) of the cooler (10) is providing connection interfaces (73, 75, 77, 79) for the inlet apertures (23, 25. 27, 29) of the runners (22, 24, 26, 28).

An integral drain assembly for a heat exchanger includes a plurality of passage walls defining a plurality of passages, each of the passage walls having a non-linear portion. Also included is a drain wall integrally formed with at least one of the passage walls to define a drain for each of the plurality of passages, the drain wall located proximate the non-linear portion of each of the plurality of passage walls.

An existing or new intercooler system is provided with modular fixed and removable mounting and support bracket plates that offers easy adaptability, reparability, serviceability that eliminates the need to replace an entire intercooler because a vehicle or automotive set up has been changed, portions of it has been damaged or because it has become clogged with debris. The modular and removable mounting and support bracket plates can turn existing or new intercoolers from a single automotive part into an automotive system with modular parts of different types and sizes that can be reconfigured, changed or replaced to make intercoolers fit different types of automotive system applications. These modular fixed and removable mounting and support bracket plates eliminates the need for all metal parts and permanent welding. The intercooler system having end tanks made of composite material with carbon fiber to eliminate heat retention and secured by bonding material.

A combined cycle power generation and storage system is shown. A liquid air energy storage system uses excess power to liquefy air and stores it in a liquid state. A combustion engine produces power by combustion of a carbon-based fuel along with an exhaust stream containing carbon dioxide. A heat recovery system exchanges heat from the exhaust stream to air from the liquid air storage system, and thereby produce a cooled exhaust stream and heated air. An air expansion machine recovers power by expansion of heated air from the heat recovery system. A separation system separates carbon dioxide from ambient air prior to liquefaction during operation of the liquid air energy storage system, and separates carbon dioxide from the cooled exhaust stream during operation of the combustion engine prior to emission of the cooled exhaust stream to atmosphere.

A charge air cooler for an internal combustion engine, includes a charge air inlet and a charge air outlet which are fluidly connected with each other via multiple charge air channels which are arranged parallel to each other and arranged parallel to each other and subjectable to a coolant flow; and at least one flow guide element arranged upstream of the charge air channels, wherein the flow guide element at least in one operating state of the internal combustion engine deflects charge air entering through the charge air inlet the direction of a condensate accumulation volume of the charge air cooler.
