Problems solved by technology

[0007] According to the prior art, the consequence of this dependency which should be taken into account in the design of dry sump lubrication is that the arrangement of the container is to have a reliable, i.e. continuous, supply of oil, which is fundamental for achieving the most compact possible engine space packaging. Targets usually have adverse effects

Embodiment Construction

[0079] Detailed description of the preferred embodiment

[0080]The internal combustion engine 1 is equipped with an intake area 2 for supplying fresh air and comprises a cylinder head 14, a cylinder block 15 and a collection point 16 which is arranged below the cylinder block 15 and where oil 18 is collected to form oil Bottom case 16. In this case, the return of oil from the cylinder head 14 and cylinder block 15 takes place in a gravity-driven manner, as clearly indicated by the arrows.

[0081] figure 1 The illustrated internal combustion engine 1 has a dry sump lubrication 3 , the oil 18 collected at a collection point 16 is led via a discharge line 4 into a container 5 for storing the oil 18 . In order to prevent undesired backflow, a non-return valve 13 is arranged in the discharge line 4 . The oil 18 introduced into the container 5 forms an oil level 19 . Above the oil level 19 there is a gas 17 which fills the remaining space of the container 5 .

Abstract

The present invention relates to an internal combustion engine which is used for supplying fresh air to an air inlet area of the internal combustion engine and has dry sump lubrication. The internal combustion engine is connected with a container used for storing oil through a discharge tube for introducing the oil collected in the internal combustion engine to the container. On the other hand, the internal combustion engine is connected with the container through a feeding tube for using an oil pump provided in the feeding tube and supplying the oil to the internal combustion engine. A ventilation pipe is branched from the container, is introduced to a vacuum loading part in the air inlet area and is furthermore used for feeding the fresh air into a fresh air tube of the container for introducing the container. A control component is provided in the fresh air tube. The feeding of the fresh air into the container can be controlled through the control component. The invention furthemore comprises a method for operating the internal combustion engine. The system and the method provide larger freedom degree in the aspece of container settlement and particularly allows the compact assembling of all driving units.

Description

technical field [0001] The invention relates to an internal combustion engine having an air intake area for supplying fresh air to the internal combustion engine and having dry sump lubrication. The internal combustion engine is connected on the one hand to a container for storing oil via a discharge line in order to introduce oil collected in the internal combustion engine into the container; and the internal combustion engine is connected to the container via a supply line on the other hand, In order to draw oil from the container with an oil pump arranged in the supply line and supply the oil to the internal combustion engine. [0002] The invention further relates to a method of operating such an internal combustion engine. Background technique [0003] In internal combustion engines with dry sump lubrication, the oil that normally collects in the internal combustion engine under the crankcase called the oil sump is pumped via a drain line and with an oil pump to a sepa...
