An electric pump actuator for a continuously variable transmission includes a gear wheel pump, a first electric motor, a second electric motor, and an electric control unit. The gear wheel pump has a first gear wheel and a second gear wheel meshing with the first gear wheel. The first electric motor is for actuating the first gear wheel, and the second electric motor is for actuating the second gear wheel independent of the first gear wheel. The electronic control unit is arranged to control the first electric motor to transmit a first torque to the first gear wheel, and control the second electric motor to transmit a second torque to the second gear wheel that is set against the first torque in at least one rotation angle range.

To improve maintenance workability of fuel injection valves in multiple throttle bodies, a distribution member (D) is provided with a fuel distribution path () communicating with a fuel inflow path (), throttle body mounting holes () and injection valve support member mounting holes (), injection valve support members (S, S) are provided with injection valve support bosses (), the distribution member (D) is screwed to the one and other side throttle bodies (T, T) via the throttle body mounting holes (), the other side end surfaces () of the injection valve support members (S, S) are screwed on one and the other side end surfaces () of the distribution member (D), and the other and one side fuel injection valves (Ja, Jb) are held by the injection valve support members (S, S) and the other and one side throttle body (T, T) respectively.

Disclosed is a fuel cell system provided with a fuel cell (), a water tank () which stores water to be supplied to the fuel cell, and a heating device () which defrosts the water inside the tank during activation of the fuel cell. The fuel cell system has a switch () which signals activation of the fuel cell; at least one temperature sensor () which detects a temperature inside the water tank; a pump () which conveys water from the water tank to the fuel cell; a heater () which warms the pump; and a controller (). The controller () is programmed to read a start temperature from said at least one temperature sensor () upon reception of a signal from the switch (); calculate on the basis of the read start temperature a first warm-up period (tw) required for the water inside the water tank () to reach a predetermined temperature (Tw) greater than zero degrees centigrade; calculate on the basis of the read start temperature a second warm-up period (tH) required to defrost ice inside the pump () using the heater; set a start time (t) for warm-up of the pump () using the heater on the basis of a difference (Dt) between the first warm-up period (tw) and the second warm-up period (tH); and control the heater to begin generating heat at the start time (t) for warm-up of the pump ().
