A priming pump may include a housing; an inlet passageway inside of the housing; an outlet passageway inside of the housing; a divider, inside of the housing, separating the inlet passageway and the outlet passageway; a connecting passageway through the divider in fluid communication with the inlet passageway and the outlet passageway; a valve, disposed in the connecting passageway, configured for one-way fluid flow from the inlet passageway to the outlet passageway; a rotary pump, inside of the housing, having an inlet in fluid communication with the inlet passageway and an outlet in fluid communication with the outlet passageway; and a shaft connected to the rotary pump and extending through the housing, the shaft configured for rotation by an external driving mechanism.

Provided is a configuration which prevents an engine from being unable to start in the state in which dew condensation occurred in a fuel injection pump and froze. The present invention relates to a fuel injection pump which is provided with a pump body and a hydraulic head and driven by an engine, and is characterized in that while the engine is in operation, the temperature of the hydraulic head is increased to a dew-point temperature or higher. Consequently, it is possible to increase the temperature of the hydraulic head and remove water in the fuel injection pump while the engine is in operation. Accordingly, the engine can be prevented from being unable to start in the state that dew condensation occurred in the fuel injection pump and froze.

A motor vehicle fuel pump cover is provided for covering a fuel guide region of a motor vehicle fuel pump by way of a cover housing. A phase change core is received in the cover housing. The phase change core is designed to change the phase state thereof while receiving thermal energy from the fuel guide region. The phase change core is designed for phase change at a temperature of more than 60 C.

A fuel injection pump for a diesel engine, including: a control rack an in a rack chamber formed between a pump head and a pump housing, and configured to adjust a fuel injection amount; a transmission shaft rotatably supported by a transmission shaft hole formed in the pump housing; and a lubricating oil passage formed in the pump housing, and configured to pressure-feed lubricating oil between the transmission shaft and the transmission shaft hole. The transmission shaft has an oil passage therein through which passage the lubricating oil pressure-fed to the lubricating oil passage partially passes, a first opening of the oil passage is communicated with the lubricating oil passage, and a second opening of the oil passage is formed on the outer circumferential surface of an upper portion of the transmission shaft, nearby the control rack.

This invention relates to a starter system for an electronically controlled internal combustion engine which is particularly, although not exclusively, suitable for use on electronically controlled diesel engines used in trackless mining machinery. The starter system adapted to actuate an electronic engine control module (ECM) of an electronically controlled fuel-injection engine when the engine is started, wherein the engine comprises a fuel tank and a high pressure injector pump which are arranged in flow communication with a series of injector nozzles. The starter system is characterised therein that it comprises an alternator which is operatively associated with the ECM for actuating the ECM, the arrangement being such that when the engine is started, the alternator supplies the ECM with electrical current before the engine is cranked.
