摘要： Example embodiments for reducing thermal load in one or more exhaust gas lines are provided. One embodiment includes an internal combustion engine with liquid cooling, comprising at least one exhaust gas line, at least one coolant jacket, and a common boundary wall separating the at least one exhaust gas line and the at least one coolant jacket, wherein the common boundary wall includes a surface structure provided on sides of the coolant jacket in at least one locally limited region. In this way, the surface structure on the sides of the coolant jacket may increase heat transfer to reduce thermal loading.

摘要： A system for an engine comprising: a crankshaft with four crank throws, wherein, the first and the second crank throw are arranged offset by 180° CA from the third and the fourth crank throws; four cylinders corresponding to the four crank throws, the four cylinders arranged in two cylinder groups, the first cylinder group comprising the first and second cylinder, and the second cylinder group comprising the third and fourth cylinder; an exhaust manifold, wherein, exhaust lines within each of the two cylinder groups merge forming two component exhaust lines, and the two component exhaust lines merge into an overall exhaust line; and an ignition sequence such that each ignition is offset by 180° CA, and ignition of cylinders within the two cylinder groups is offset by 360° CA. In this way exhaust lines within the exhaust manifold can remain short and backpressure from sequential, adjacent cylinder ignition is minimized.

摘要： A linearly aligned four-cylinder internal combustion engine system operated in a 1-3-4-2 sequence, comprising a cylinder head connected with a cylinder block wherein each cylinder has at least one exhaust port to discharge exhaust gasses via an exhaust gas discharge system, for which an exhaust gas pipe is connected at each exhaust port; wherein the exhaust gas pipes of the cylinders that merge in stages into a common exhaust gas pipe and the exhaust gas discharge system emerges outside of the cylinder head. Thus exhaust gas from consecutive ignitions in adjacent cylinders is separated for a distance throughout the engine head to reduce mutual influencing in adjacent cylinders with consecutive ignitions.
