JPH075884U - Surplus energy converter for automobile - Google Patents

Abstract

(57) [Summary] (Corrected) [Purpose] Converting the rotational energy generated during deceleration, which was conventionally discarded, into high pressure oil for storage, and converting the high pressure oil stored during acceleration into rotational energy for propulsion. To use. [Structure] A hydraulic pump 11 having a clutch 5 is attached to a propeller shaft 8 connected to a rear wheel or a front wheel, and the hydraulic pump is rotated by rotational energy generated from the rear wheel or the front wheel at the time of deceleration to convert into high pressure oil. Then, the high-pressure oil stored in the high-pressure tank (accumulator) 17 is stored in the high-pressure tank (accumulator) at the time of acceleration. Alternatively, the rotational energy is transmitted to the front wheels and used for propulsion.

Description

[Detailed description of the device]

Industrial Application Field In recent years, the exhaust gas emitted from diesel engines used for trucks and buses has become a problem. Especially when starting or accelerating, a large amount of exhaust gas is generated, further expanding air pollution. Some of them are also converted to electrical energy and used effectively, but the major problem is the large conversion loss. The device we devised this time stores energy to be discarded by engine braking etc. in a high-pressure tank in high-pressure oil, and uses the high-pressure oil that has been stored all at once at the time of starting or accelerating to assist the main engine, and when starting or accelerating. It reduces the amount of waste gas generated or reduces fuel consumption. Since the present invention stores oil at high pressure in a high-pressure tank, the device is simple and the energy conversion loss is small.

Description of Structure When the engine brake is driven, the propeller shaft receives a reverse force, and an electric signal causes the clutch to attach to the pulley, the pulley to start rotating, and through the belt, the 24 pulley, and 11 pulley. Accelerator, (12) Rotate the high pressure pump, (14) From the oil tank, pass through the suction pipe (13), enter the high pressure pump (12), and convert into high pressure oil by the high pressure pump (12). 25 ▼ Pass through the high pressure pipe, enter the ▲ 20 ▼ control valve, and accumulate in the ▲ 17 ▼ high pressure tank. When the ▲ 17 ▼ high pressure tank is full, the ▲ 14 ▼ oil tank through the ▲ 18 ▼ return pipe. Returned to. At the time of starting or accelerating, an electric signal will open the (21) open / close valve, and at the same time, a clutch and pulley will be attached, and high-pressure oil will pass through the (22) oil outlet pipe, (16) hydraulic motor, and (15). ▼ Rotate the decelerator, ▲ 23 ▼ The power of rotation is applied to the propeller shaft through the pulley, belt, pulley and clutch, and the engine assists, so the engine rotates smoothly and exhaust gas is reduced.
