Problems solved by technology
[0003] The high-pressure common rail fuel system is different from the original mechanical pump fuel system and the electronically controlled unit pump fuel system. The ordinary fuel input pressure cannot meet the working requirements of the high-pressure common rail fuel system. The cover also cannot satisfy the installation of the oil delivery pressurization device, and the function is single, which needs to be improved

The invention discloses a common rail diesel engine gear chamber cover. The common rail diesel engine gear chamber cover comprises a gear chamber cover body, a hand-pulling throttle installation structure, a high-pressure oil injection pump installation structure, a signal gathering device installation structure and an oil conveying pump installation structure, wherein the hand-pulling throttle installation structure is arranged on the left side of the gear chamber cover body, the signal gathering device installation structure is arranged on the right side of the gear chamber cover body, the high-pressure oil injection pump installation structure is arranged at the top of the gear chamber cover body, the oil conveying pump installation structure is arranged on the front face of the gear chamber cover body, the high-pressure oil injection pump installation structure comprises a first platform surface located at the top of the gear chamber cover body, and the first platform surface is provided with a first through hole extending into the gear chamber cover body. By means of the above-mentioned method, the common rail diesel engine gear chamber cover is compact in volume, lightweightin design and convenient to install, working of an oil conveying pump is conveniently driven through rotation of a crank shaft, and adequate diesel oil is guaranteed to be conveyed from a fuel oil boxto a high-pressure oil injection pump.
Description
technical field [0001] The invention relates to the technical field of diesel engines, in particular to a gear chamber cover of a common rail diesel engine. Background technique [0002] In order to actively respond to the country's blue sky defense war and make the single-cylinder diesel engine meet the non-road National IV standard, it is urgent to upgrade the single-cylinder diesel engine. After several years of research, the current technical route of using high-pressure common rail fuel system for single-cylinder diesel engines can meet the emission requirements. [0003] The high-pressure common rail fuel system is different from the original mechanical pump fuel system and the electronically controlled unit pump fuel system. The ordinary fuel input pressure cannot meet the working requirements of the high-pressure common rail fuel system. The cover also cannot satisfy the installation of the oil delivery pressurization device, has a single function and needs to be im...
