The present invention relates to a cooling jet nozzle (10) for an engine piston. The nozzle (10) comprises a cooling stream pathway (14), in which the internal cross-sectional dimensions of the pathway vary along the length of the pathway; and a plunger (28) located within the cooling stream pathway to impinge a cooling feedstream received within the pathway to provide a cooling jet. The plunger (28) is axially moveable within the pathway to adjust the internal cross-sectional dimensions of the cooling jet.

An internal combustion engine body includes a cylinder block including a plurality of cylinders, a first water jacket, and a second water jacket, and a cylinder head including an in-head water jacket. The in-head water jacket includes an intake-side flow passage. The cylinder block and the cylinder head are provided such that a flow rate of coolant that directly flows into the intake-side flow passage after flowing into the first water jacket is higher than a flow rate of coolant directly flows into any region other than the intake-side flow passage after flowing into the first water jacket.

The present disclosure relates to a heat exchanger, for example an indirect charge air cooler for an internal combustion engine. The heat exchanger includes a heat exchanger block including a first channel system for a first fluid and a second channel system for a second fluid that is fluidically separate from the first channel system. Two opposite side parts and two opposite end parts are structured and arranged to fluidically delimit the second channel system. At least one frame part is connected with a respective edge of the two side parts and of the two end parts. An air inlet box is connected to the at least one frame part via a seal. The heat exchanger block has a width b1 and a height h1, and the seal has a width b.sub.2 and a height h.sub.2, where b.sub.1≥b.sub.2 and h.sub.1≥h.sub.2.

The invention relates to an oil-water heat exchanger, in particular for connection to an internal combustion engine of a motor vehicle, comprising at least one electric heating coating (13) which is applied to an outer side and/or in the interior of the heat exchanger.

An aircraft propulsion system comprising a reciprocating liquid cooled engine housed within the fuselage driving twin fuselage mounted ducted-fans is disclosed. The propulsion system may be liquid cooled with a liquid cooled exhaust and at least one turbocharger. The ducted-fans may run fan blade tip speeds of up to 97% Mach driven by a near constant RPM engine through a continuously variable transmission. The propulsion system may be low noise and may meet environmental standards typical in the automotive industry.
