Single-blade type engine oil pump driven by auxiliary pneumatic motor

Abstract

The invention belongs to the technical field of automobile engine pre-lubrication, and particularly relates to a single-blade type engine oil pump driven by an auxiliary pneumatic motor. The engine oil pump comprises an engine oil pump shell, engine oil pump blades, an engine oil pump rotor, a rotor shaft, a woodruff key, a locking nut, a transmission gear, an engine oil pump cover, a bolt, a pneumatic motor shell, pneumatic motor blades, a pneumatic motor rotor, a first rolling column, a second rolling column, an ECU, a high-pressure air tank, and an electromagnetic valve. According to the single-blade type engine oil pump driven by the auxiliary pneumatic motor, when an engine needs to be started, the ECU controls the electromagnetic valve to open, so that the pneumatic motor drives theengine oil pump to pump oil, the electromagnetic valve is automatically switched off after ten seconds, so that the pre-lubrication before the engine is started is completed, which does not need to consume electric energy of an automobile storage battery, and the engine can conduct complete pre-lubrication and lubrication only by installing one engine oil pump, so that the cost and the space are saved.

Description

technical field [0001] The invention relates to the technical field of automobile engine pre-lubrication, in particular to a single-group vane type oil pump driven by an auxiliary air motor. Background technique [0002] According to statistics, at present, about 30% of the world's energy is consumed in various forms of friction, and the same is true for engines. The internal wear and tear loss power of engines in different technical states accounts for 20% to 25% of the indicated power, and the wear is serious. The engine can even reach about 35%. The wear and tear of the vehicle engine is mainly manifested at the moment of starting, especially when it is cold or hot. The joint test of the American Society of Automotive Engineers and Douglas shows that the wear of the engine during cold start accounts for between 60% and 80% of the total wear. [0003] With the traditional vane-type oil pump, when the engine is cold started, the speed is slow, and the crankshaft cannot pr...

Problems solved by technology

The disadvantage of this method is that it requires a larger oil reservoir, takes up a lot of space and has limited oil storage capacity. When the engine fails to start for the first time, the accumulator cannot perform the second engine start pre-lubrication due to the lack of oil storage process.
