Abstract

The present invention provides an internal combustion engine. The present invention relates to an internal combustion engine (100) comprising a first set of cylinders comprising: a first two-stroke compression cylinder (102) housing a first compression piston (122) connected to a first crank shaft (150); an intermediate two-stroke compression cylinder (104) housing an intermediate compression piston (124), wherein said second two-stroke compression cylinder (104) is configured to receive compressed gas from said first two-stroke compression cylinder (102); and a first four-stroke combustion cylinder (108) housing a first combustion piston (128), wherein said first four-stroke combustion cylinder (108) is configured to receive compressed gas from said intermediate two-stroke compression cylinder (104); wherein the internal combustion engine further comprises a second set of cylinders comprising: a second two-stroke compression cylinder (106) housing a second compression piston (126) connected to said first crank shaft (150), wherein said second two-stroke compression cylinder (106) is configured to provide compressed gas to said intermediate two-stroke compression cylinder (104); and a second four-stroke combustion cylinder (110) housing a second combustion piston (130), wherein said second four-stroke combustion cylinder (110) is configured to receive compressed gas from said intermediate two-stroke compression cylinder (104); wherein each one of said intermediate compression piston (124) and said first (128) and second (130) combustion pistons are connected to a second crank shaft (154), said second crank shaft (154) being configured to rotate with a speed of at least twice the speed of said first crank shaft (150).

Description

technical field [0001] The invention relates to an internal combustion engine. The invention is applicable to vehicles, especially heavy vehicles such as trucks. However, although the invention will primarily be described in relation to trucks, the internal combustion engine is of course also applicable to other types of vehicles, such as cars, industrial construction machines, wheel loaders and the like. Background technique [0002] The demand for internal combustion engines has grown steadily over the years, and engines have been continuously developed to meet the various needs of the market. Reduced exhaust, increased engine efficiency (ie, reduced fuel consumption), and lower engine noise levels are some of the many criteria that become important aspects when selecting a vehicle engine. Furthermore, in the field of trucks, there are applicable legal norms which, for example, determine the maximum permissible amount of exhaust gas pollution. Further, it is important t...
