20150219005 | METHOD OF IMPROVING CHARGE AIR CONDITION IN AIR-COOLED CHARGE AIR COOLERS - A charge air system of a motor vehicle having a charger disposed in a charge air circuit and an air-cooled charge air cooler in fluid communication with the charger. The charge air system further includes a pre-cooler is in fluid communication with the air-cooled charge air cooler and an engine coolant circuit in heat exchange communication with the pre-cooler. The engine coolant circuit configured to deliver a flow of coolant through an engine of the motor vehicle. | 2015-08-06 |
20150219006 | CYLINDER HEAD WITH COUNTERSINK - A cylinder head of a static spark-ignited gas engine may include at least two exhaust ports, at least two inlet ports, at least one cylinder axis, and a bottom side. Each inlet port runs to the bottom side of the cylinder head and may have a valve seat for inlet valve. Each valve seat may have a corresponding center axis. At least one inlet port has a countersink in the border area of the bottom side. The countersink may have an offset axis shifted from the corresponding center axis. The countersink may also have a maximum radius with reference to the corresponding center axis. The maximum radius and a straight line may form an angle φ. The straight line may connect the cylinder axis with the corresponding center axis. The angle φ may fulfill the following condition: 70°<=φ<=110°. | 2015-08-06 |
