摘要： A method of operating an engine (10) is provided. The engine includes a housing (12) having a combustion chamber (1), a piston (14) disposed adjacent the combustion chamber, a crankshaft (60) connected to the piston, an intake valve (80) associated with the combustion chamber, and an exhaust valve (92) associated with the combustion chamber. The method also includes opening the intake valve after a power stroke (126) of the piston begins and closing the intake valve before the exhaust stroke (128) ends. Furthermore, the method includes causing the exhaust valve to be open for part of an intake stroke (154) of the piston and closing the exhaust valve at least about 30 degrees of crankshaft rotation after the intake stroke begins.

摘要： Engines may be provided with one or more balance shafts to provide a balancing effect to the engine during operation. Normally, the balance shafts are located where they can be driven by the engine's front end drive assembly. However, driving balance shafts or any other engine accessory off the front end drive assembly has implications in respect of both increased engine noise and extended engine length. An engine accessory drive in accordance with the present invention reduces engine noise and engine length while providing a balancing effect. An engine accessory drive includes a primary drive (7) drivable by the crankshaft (9) of the engine and a rotary member (5) such as a drive pulley mounted on a drive shaft (27) which is drivable by the primary drive (8).

摘要： A method for managing state of charge of a battery of an electric work vehicle to be ready to return to work at a return to work time. Data comprising an expected date and time of return to work is obtained from the output of a user interface and used to calculate an expected duration of immobilization of the electric work vehicle. A charge rate is determined based on the expected duration of immobilization of the work vehicle and a targeted charge increase. A charging start time is calculated such that at the return to work time an actual state of charge of the battery is a target operational state of charge value. The temperature of the battery is adjusted such that the battery is at a target temperature at the charging start time. The charge cycle is started at the charging start time.
