Abstract: Between a movable core chamber and a fuel supply passage, a needle guide slidably supports a needle fixed to a movable core. The needle guide has a communication hole which fluidly connects the movable core chamber and the fuel supply passage. An opening sectional area of the communication hole is defined in such a manner that a fuel discharged amount decreases as an energization start time of a coil is delayed. In a suction stroke, it is restricted that the movable core and the needle bounce toward the fixed core after the needle biases a suction valve toward a stopper by means of a biasing force of a second spring. A relationship between the energization start time of the coil and the fuel discharged amount is properly maintained, so that the fuel discharged amount of the high-pressure pump can be controlled correctly.

Abstract: An aftermarket modification for diesel engines that operate in cold environments particularly those using a liquid-to-air oil cooler. Engine oil can be routed to a bypass module having a thermostatic element that directs the oil to bypass the oil cooler and return to the engine if the engine oil is below the desired temperature. Once the desired oil temperature is reached, the thermostatic element moves toward a closed position to direct oil through the oil cooler. A pressure bypass element can be incorporated into the bypass module. If the pressure differential between the inlet and outlet of the cooler exceeds a set point, the bypass element moves toward an open position to direct a portion of the oil to bypass the oil cooler.
