A motor-driven compressor includes a housing having at one end thereof an accommodation space, an electric motor, a motor driver circuit provided in the accommodation space and having a circuit board, a connector having a bus bar electrically connected to the circuit board, and a cylindrical portion located at the one end of the housing and extending toward the direction close to the electric motor. The housing has a mounting hole communicating with the accommodation space and the interior of the cylindrical portion. The bus bar has a bent shape having opposite ends extended toward the direction close to the electric motor. The connector is disposed in the mounting hole with one end of the bus bar inserted in the cylindrical portion and the other end of the bus bar inserted in the accommodation space. The mounting hole is closed up by a cover with a seal member provided therebetween.

There is disclosed a vacuum cleaner including a dust separation section which separates air and dust flowing toward an intake port of a motor blower through a connection port of a cleaner main body. The dust separation section includes an air path forming member which performs a separation function. The forming member includes an introductory port, a derivative port, and an opening disposed between these. In the separation function, while dust-containing air flows toward the derivative port from the introductory port, a part of the air is sucked by the motor blower through the opening. Accordingly, the air is separated from the dust which goes straight in the air path forming member with inertia.

An internal combustion engine has a crankcase coupled to a lower end of a cylinder block, the crankcase including an upper case integrally formed with the cylinder block and a lower case fixed to the upper case. The upper and lower cases have a plurality of journal support walls projecting from inner wall surfaces thereof. An oil pan is fixed to the lower open end of the lower case. A crankshaft is rotatably sandwiched by the journal support walls. A breather chamber is mounted on one side of the crankcase and defined by recesses on confronting surfaces of the upper and lower cases, the breather chamber having one end communicating with the crank chamber and an opposite end communicating with an air intake system. At least one balancer shaft is rotatably supported in a balancer chamber mounted on one side of the crankcase. The upper and lower cases define substantially semicylindrical recesses therein which jointly constitute bearings in which the crankshaft and the balancer shaft are rotatably supported. At least one of the upper and lower mating surfaces has an oil groove communicating with said recesses for being supplied with lubricating oil. The oil groove and the recesses are formed upon casting of the upper or lower case having the at least one of the upper and lower mating surfaces.
摘要:
An upper limit value of an upward gradient of a road surface for starting neutral coasting is set to be larger than an upper limit of the upward gradient of the road surface for starting free-run coasting, so, when the upward gradient is relatively large and a coasting distance is short, the vehicle is caused to travel in the neutral coasting, and stop and restart of the engine are not carried out. Therefore, a decrease in drivability of the vehicle is suppressed. When the upward gradient is relatively small and the coasting distance is long, the vehicle is caused to travel in the free-run coasting, and supply of fuel to the engine is stopped, so fuel economy of the vehicle is obtained. Thus, it is possible to achieve both fuel economy and drivability of the vehicle during coasting on an upward gradient.

A running control device is configured to execute an engine coupling running mode performed with an engine and wheels connected by a connecting/disconnecting device, a neutral inertia running mode performed with the engine separated from the wheels by the connecting/disconnecting device while the engine is supplied with fuel and allowed to perform self-sustaining rotation, and a free-run inertia running mode performed with the engine separated from the wheels by the connecting/disconnecting device while fuel supply to the engine is stopped to stop rotation. The neutral inertia running mode is terminated when an operation amount of the accelerator pedal becomes equal to or greater than a predefined first determination value. The free-run inertia running mode is terminated when an operation amount of the accelerator pedal becomes equal to or greater than a predefined second determination value larger than the first determination value.

A running control device of a vehicle includes an engine and a brake booster amplifying a brake force by forming a negative pressure in a negative pressure tank by rotation of the engine. The running control device is configured to execute an engine brake running mode performed with the engine coupled to wheels such that an engine brake is applied by driven rotation of the engine and an inertia running mode performed with an engine brake force made lower than that of the engine brake running mode. The running control device executes a first inertia running mode performed with the rotation of the engine stopped and a second inertia running mode performed with the engine kept rotating as the inertia running mode in accordance with predefined respective execution conditions. The running control device comprises a prediction portion configured to predict a necessity of the negative pressure.
