Embodiment Construction

[0014] Refer to the following figure 1 and 2 The present invention is described in detail according to enlarged detail drawings.

[0015] figure 1 A partial view of an internal combustion engine according to the invention is shown in the region of three cylinders, only cylinder liners 10 being shown for the cylinders. Each cylinder is equipped with a fuel injector 11 for injecting fuel into the cylinder. The fuel injector 11 is part of a fuel supply system according to the rail principle, wherein the injection pressure is provided by a pumping device 12 of the fuel supply system. The pumping device 12 conveys fuel from a low-pressure region of the fuel supply to a high-pressure region of the fuel supply. In the exemplary embodiment shown, the pumping device 12 consists of two so-called high-pressure cartridge pumps 13 which can be driven by a camshaft 14 .

[0016] It should be pointed out here that a high-pressure monobloc pump can also be used as pumping device. Furt...

Abstract

The invention relates to an internal combustion engine, namely a rail-tube internal combustion engine, which has a plurality of cylinders, wherein each cylinder is equipped with at least one intake valve for combustion air, at least one exhaust valve for exhaust gases and at least one fuel The fuel injector (11) used, the internal combustion engine also has a pumping device (12), which is used to transport the fuel from the low-pressure area of ​​the fuel supply equipment to the high-pressure area of ​​the fuel supply equipment, wherein the pumping device (12) and the injection The high-pressure area between the oil nozzles (11) is provided with a pressure accumulator system, and the pressure accumulator system has a plurality of pressure accumulator units (6), which are connected to each other through the delivery pipeline (17). According to the invention, the control device for the or each intake valve and the or each or each exhaust valve of the intake valve of the cylinder and the corresponding accumulator unit (16) of the accumulator system are arranged in a respective On the common supporting device (15).

Description

technical field [0001] The invention relates to an internal combustion engine. Background technique [0002] DE 10157135 B4 discloses a rail-type internal combustion engine with a plurality of cylinders, wherein each cylinder is equipped with an injector of a fuel supply system. The fuel supply device includes a pumping device for conveying fuel from a low-pressure region of the fuel supply device to a high-pressure region of the fuel supply device, wherein a pressure accumulator is arranged between the pumping device and the injector in the high-pressure region system. A pressure accumulator system, also known as a pressure accumulator, has a plurality of pressure accumulator cells, which are connected to one another via delivery lines. Fuel can be injected into each cylinder via injectors, wherein each cylinder is equipped with at least one intake valve for combustion air and at least one exhaust valve for exhaust gases in addition to the injectors for fuel. valve.
