摘要： A camshaft drive arrangement for an internal combustion engine wherein the drive includes first and second intermediate shafts journaled directly within the cylinder block. The first intermediate shaft is driven directly to the crankshaft and the second intermediate shaft is driven from the first intermediate shaft by a flexible transmitter drive. The second intermediate shaft drives a camshaft journaled in the cylinder head by a second flexible transmitter drive.

摘要： A positive crankcase ventilation (PCV) valve installation structure for installing a PCV valve of an engine on an engine body includes: a blow-by gas recirculation system that includes a ventilation hose that connects the engine body to an intake device introducing outside air into the engine body and that has a recirculation passage recirculating blow-by gas arising in the engine body to the intake device and an oil cooler device that exchanges heat between lubricating oil and a medium solution that is lower in temperature than the lubricating oil; and a cover that transfers heat of the oil cooler device to the PCV valve.

摘要： A lightweight high-strength cylinder block that is configured so as to provide an enlargement at one end thereof that defines a bell housing. The enlargement is provided with cavities, however, so as to lighten the weight of the cylinder block without substantially reducing its strength. At least one of these cavities can provide for communication of oil return and/or crankcase ventilating gases and also may function as a thermostat housing. An embodiment wherein the cylinder block extends below the crank shaft axis to form the upper portion of the crankcase is also disclosed.
