Abstract

The invention discloses engineering machinery and an engine starting ignition system thereof. The engine starting ignition system comprises a lower car engine, a first oil pump, a first reversing valve, an upper car engine and a second oil pump. The first oil pump is connected with the lower car engine in a driving mode, and the second oil pump is connected with the upper car engine in a driving mode. A first oil port of the first oil pump is connected with an oil tank, and a second oil port of the first oil pump is connected with the first oil port of the second oil pump through the first reversing valve. Compared with the prior art, the engine starting ignition system can avoid the fact that the upper car engine cannot be started when a storage battery is low in power or a starting motor loses efficacy (for example, under low temperature environment). In addition, due to the fact that the lower car engine can be fully utilized and a part of original hydraulic elements can be utilized (for example, a working oil pump of an original hydraulic system of a lower car can serve as the first oil pump), the resource utilization rate is improved.

Description

technical field [0001] The invention relates to the technical field of engine starting, in particular to an engine starting ignition system of a construction machine and a construction machine. Background technique [0002] With the rapid development of the national economy, construction machinery is widely used in roads, bridges, urban construction and petrochemical infrastructure, etc. The market has higher and higher requirements for the environmental adaptability of construction machinery. Generally speaking, it is generally required that construction machinery can still work normally in a working environment below minus 20°C. At present, construction machinery is mostly composed of getting off the car and the car on the car. The car engine, starter motor and battery are arranged in the car. The starter motor converts the electric energy of the battery into mechanical energy to drive the engine on the car. The flywheel rotates to start, and the output of the engine is g...
