High pressure oil passage by-pass economizer of diesel-powered car

Abstract

The invention discloses a high-pressure oil passage by-pass economizer of a diesel-powered car, comprising a circuit control switch, a high-pressure oil passage by-pass one-way valve, an oil return cylinder, an air cylinder and an electromagnetic valve. The circuit control switch and the electromagnetic valve that is connected with an air compressor can automatically select an air throttle or set a speed and even set whether the electromagnetic valve operate or not under a throttle normally closed condition; the electromagnetic valve is connected with the air cylinder to drive the oil return cylinder connected to the air cylinder; two to six the high pressure oil passage by-pass one-way valves corresponding to skew notches on a push rod are arranged on one side of an oil cylinder sleeve at intervals; the high pressure oil passage by-pass one-way valves are serially connected between a high pressure oil pipe and an oil injector via a three-way high pressure oil pipe connector; when the push rod is pushed to eject a stepped spool, the high pressure diesel is released through a stepped hole to the oil cylinder and flows back to the oil tank, indirectly blocking oil supply to a deactivation cylinder of an engine; when the push rod in the oil return cylinder returns back, then the stepped spool is restored, the oil return is turned off, and the oil supply to the engine of the car is recovered. The invention has advantages of low cost, high degree of automation, safety, reliability, significant oil economization effect and the like, and is specially suitable for diesel-powered cars.

Description

1. Technical field [0001] The invention relates to a fuel-saving device for automobiles, in particular to a high-pressure oil road bypass fuel-saving device for diesel-powered automobiles, which is especially suitable for diesel-powered automobiles. 2. Background technology [0002] The actual load of the automobile only reaches 40% to 50% of the design load when it relies on the kinetic energy inertial force of its own running or the potential energy of downhill sliding. According to the survey and statistics of relevant departments: the ratio of running cars in cities is about 25% to 35%, and the ratio of running cars on roads is about 20% to 30%. In order to save energy consumption during gliding, many scientific research institutions and automobile manufacturing companies have conducted a lot of research in this area, and have achieved various results. Among them, the most significant achievement in energy saving and consumption reduction is to stop part of the engine cy...

Problems solved by technology

It has the following deficiencies: First, in order to prevent insufficient pressure of the compressed air source stored in the car, the driver needs to always pay attention to whether the compressed air stored in the car has enough pressure, which increases the difficulty of the driver's work; The pressure of the compressed air source is not enough to close the oil control valve, and the high-pressure oil flows back to the fuel tank through the oil control valve, causing the engine to partially stop, which will affect the normal driving of the car; third, for the convenience of operation, the valve should be placed in a position that is convenient for the driver to operate. Moreover, a valve and a high-pressure oil pipe of a corresponding length are required for a single-cylinder oil stop. When multiple cylinders are required to stop oil, corresponding multiple valves and multiple high-pressure oil pipes of a corresponding length are required, so that the three-way high-pressure oil pipe is too long and too long. Therefore, it not only increases the cost of the fuel economizer, but also seriously affects the pressure fluctuation time of the high-pressure oil supply and the stability of the high-pressure injection system, and also increases the possibility of high-pressure oil leakage
