| 20080236530 | ADJUSTMENT DEVICE FOR ADJUSTING THE RELATIVE ROTATIONAL ANGLE POSITION OF A CAMSHAFT IN RELATION TO A CRANKSHAFT OF AN INTERNAL COMBUSTION ENGINE - An adjustment device ( | 10-02-2008 |
| 20080264365 | Camshaft Adjuster - Traditional camshaft adjusters are connected to a lubricant circuit of an internal combustion engine. Lubricant flows which are too large flood the drive of the camshaft adjuster, which leads to needless churning losses in the drive and needless losses of the pump capacity of the lubricant for other structural components of the internal combustion engine. According to the invention, a flow element ( | 10-30-2008 |
| 20080283009 | Camshaft Adjuster - Impurities of a lubricant in traditional camshaft adjusters can cause a problem, leading to impairment in the function and service life of the camshaft adjuster. In order to address this, flow channel areas are provided in the lubricant circuit, which include a dead chamber ( | 11-20-2008 |
| 20080308054 | Camshaft Adjuster - A lubricant circuit of a camshaft adjuster is provided. In conventional camshaft adjusters, lubricant is supplied from a cylinder head to the camshaft adjuster via a supply channel ( | 12-18-2008 |

| 20090139478 | RECIPROCATING PISTON INTERNAL COMBUSTION ENGINE AND METHOD FOR DETERMINING THE WEAR OF A TRANSMISSION ELEMENT ARRANGED BETWEEN A CRANKSHAFT AND A CAMSHAFT - A method for determining a wear value of a transmission element between a crankshaft and a camshaft of a reciprocating piston internal combustion engine, in particular a timing chain or toothed belt, is provided. The camshaft is driven by the transmission element via a drive part, for example a camshaft gearwheel. In each case, at least one measurement value for the phase position of the drive part relative to the crankshaft is determined at time intervals during which the crankshaft drives the camshaft, and the wear value is determined from the difference between the measurement values. | 06-04-2009 |
| 20090199807 | METHOD FOR ADJUSTING A CAMSHAFT OF AN INTERNAL COMBUSTION ENGINE AND INTERNAL COMBUSTION ENGINE WITH AN ADJUSTABLE CAMSHAFT - A method for adjusting a camshaft of an internal combustion engine during a stop phase and during a subsequent new startup phase of the internal combustion engine. Such methods are used, in particular, in so-called start-stop designs for combustion engines. The camshaft controls intake valves and/or exhaust valves of the internal combustion engine and is adjustable by a camshaft adjuster. By a desired startup position of the camshaft adjuster, control time points of the intake valves and/or the exhaust valves are defined in which mechanical work necessary for starting the internal combustion engine is reduced and/or pollutant emissions of the internal combustion engine are reduced. In the method according to the invention it is provided that the camshaft adjuster is set in a desired stop position during the stop phase. During a first section of the startup phase, the camshaft adjuster is set from the desired stop position into the desired startup position. During a second section of the startup phase, a setting of the camshaft adjuster is performed as a function of measured operating parameters of the internal combustion engine. Furthermore, the invention relates to an internal combustion engine with a camshaft that can be adjusted by a camshaft adjuster. | 08-13-2009 |
