An internal combustion engine system includes an internal combustion engine, an exhaust system, an exhaust gas recirculation circuit and a turbocharger including a first turbine interacting with a first compressor for charging air to the internal combustion engine. An exhaust gas recirculation passage is arranged to divert exhaust gases from the internal combustion engine upstream the first turbine and to debouch the exhaust gases downstream the first compressor. The internal combustion engine includes a bleed air channel which is located to divert compressed air at a location in or downstream from the first compressor and upstream of the internal combustion engine. A second turbine is arranged for receiving bleed air from the bleed air channel to recover energy from the bleed air channel. A vehicle including such an internal combustion engine system is also provided.

An internal combustion engine; wherein at least two cylinders continuously communicate via the cylinder head; and wherein the connecting rod in one cylinder is offset from the connecting rod in the second cylinder by a first angle between 8 and 12 degrees as measured from the crankshaft, and a camshaft having a second offset of one-half of the first angle offset.

A balancer device for an internal combustion engine is provided, wherein the drive mechanism 8 and the oil pump 3 are arranged on the side opposite to driven balancer weight 135 in the axial direction of the driven balancer shaft 5.

An engine without a compressor or a turbine comprises a combustion chamber for burning a fuel-air mixture formed by mixing a fuel with outside air; and an outside air introduction part for introducing outside air into the combustion chamber. The outside air introduction part comprises an intake main port for introducing outside air into the combustion chamber from the direction along the central axis of the combustion chamber and a plurality of intake sub-ports for introducing outside air into the combustion chamber from the direction toward the central axis. The intake sub-ports comprise ejection openings capable of ejecting outside air toward a collision point inside the combustion chamber. Streams of outside air ejected from the ejection openings of the intake sub-ports mutually collide at the collision point and are thereby compressed.
