Embodiment Construction

[0030]Fig. 1 shows a schematic diagram of components of an engine system 1 comprising an internal combustion engine. As can be seen from FIGS. 2 and 3 , which are referred to below, the engine in this example includes six cylinders arranged in a line, whereas in FIG. 1 , only one cylinder C1 and the reciprocating piston 3 are schematically shown. At each cylinder, the communication between the corresponding cylinder and the intake passage 4 is controlled by the intake valve 5, and the communication between the corresponding cylinder and the exhaust passage 6 of the exhaust system described below is controlled by the exhaust valve 7. connected. Certainly, two or more intake valves 5 and / or two or more exhaust valves 7 may be provided at each cylinder, and for the sake of brevity of description, only each of the above components is shown in FIG. 1 one of.

[0031] The engine system 1 also includes an engine control unit (ECU) 9, which may be configured as one unit, or may be c...

Abstract

The invention relates to an engine system, and a method in an engine system comprising an internal combustion engine having at least two cylinders (C1-C6) at each of which a piston (3), at least one inlet valve (5), at least one exhaust valve (7), and fuel injection means (11), for injection of fuel directly into the cylinder (C1-C6), are provided, the engine system also comprising an engine control unit (9). The engine control unit (9) is adapted to control the engine so as to operate in a homogenous charge compression ignition mode (HCCI) in at least one of the cylinders (C1-C3), and simultaneously operate in another ignition mode (SI) in at least one of the remaining cylinders (C4-C6).

Description

[0001] This application claims the benefit of priority from patent application EP07121147.8 filed on November 20, 2007, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] The invention relates to an engine system comprising an internal combustion engine having at least two cylinders, for each of said at least two cylinders a piston, at least one intake valve, at least one exhaust valve and means for A fuel injection device that directly injects fuel into a cylinder, and the engine system also includes an engine control unit. The invention also relates to a method in such an engine system. Background technique [0003] Homogenous charge compression ignition (HCCI), allowing internal combustion engines requiring mixtures with relatively low fuel content, has great potential for reducing fuel consumption compared to conventional homogeneous mixture spark ignition operation. In addition, HCCI produces relatively small amounts o...
