Composite accumulator-assisted engine

Abstract

The invention relates to a composite energy storage assisting engine. One to four auxiliary air cylinders are added to an ordinary internal combustion engine, through the combined use of two electromagnetic valves, two-way sealing air valves and a plurality of one-way valves for the air inlet and air outlet of the auxiliary air cylinders, the multifunction of brake energy accumulation, brake, starting, acceleration assisting and normal running pressure boosting under the condition that the auxiliary air cylinders and an ordinary internal combustion engine system share a crank shaft, a cam shaft, a lubricating system, a cooling system and a timing system by using the simplest structure is realized, the structure of the whole set of device is simple, the weight is light, the lubrication and the cooling are realized through the original engine structure, the operation is safe and reliable, the processing process is mature and simple, the cost is low, the energy is saved, and the pollution is low.

Description

Technical field [0001] The invention relates to an internal combustion engine device, in particular to an engine which utilizes brakes to store energy and uses compressed air energy to assist in starting and accelerating, and belongs to the field of energy-saving internal combustion engines. Background technique [0002] At present, with more and more cars owned, coupled with the increasingly tense energy supply, the energy consumption of cars has become the number one problem in the use of cars. The fuel consumption announced by most automobile manufacturers is obtained under the condition of constant speed driving. This data is quite economical. The fuel consumption of the car on the highway is not much different from it, but why is there a big difference in fuel consumption in daily use? Woolen cloth? Even double the difference. The main reason is that the daily use is mainly in the city, the road is congested, the brakes are frequently started, and the brakes cause a l...

Problems solved by technology

[0003] In order to solve the defects of the prior art, such as complex structure, heavy weight, inconvenient lubrication, high cost, and the inability to efficiently provide start acceleration boost, normal driving boost, and brake energy storage at the same time, the present invention provides a compound energy storage power assist The engine, which makes full use of the structure and various functions of the original engine, only adds and transforms limited parts, realizes the multi-function of using air energy storage when braking, assisting when starting or accelerating, and boosting the intake air of the engine during normal driving. Utilizes the characteristic of large low-speed torque of the pneumatic engine to compensate for the defect of low-speed low-speed torque of the internal combustion engine, and plays a good role in starting assist and boosting, which can greatly reduce fuel consumption, save energy, and reduce engine harmful emissions
