Abstract

A system for improving exhaust performance of an engine of a commercial vehicle comprises an auxiliary water tank, a monitoring part, a control part and an adjusting part; an air inlet of the auxiliary water tank is connected with a ventilating port of an expansion box by the aid of a ventilating branch pipe; a water outlet of the auxiliary water tank is connected with a water inlet pipe connected with the engine by the aid of a transparent rubber hose; the monitoring part comprises a barometric sensor, a flow sensor, a temperature sensor and an ultrasonic bubble detection sensor; the control part mainly comprises a single-chip microcomputer, a control switch and an alarm; the adjusting part comprises a water tank lifting device and a pressure exhaust valve; and the monitoring part sends a monitoring signal to the control part, the alarm in the control part gives an alarm, and the control part sends a control signal to the adjusting part after the alarm is given. With the system, the vehicle can be monitored and adjusted in any state in any place; and the exhaust performance of the vehicle is improved, so that the boiling phenomenon of a cooling liquid is avoided.

Description

technical field [0001] The invention relates to the field of engine cooling systems, in particular to a system for improving the exhaust performance of a commercial vehicle engine. Background technique [0002] The exhaust performance of an automobile engine is mainly reflected by the degassing system. The main body of the commercial vehicle engine degassing system is the auxiliary water tank. The auxiliary water tank mainly has the following functions: 1. Provide space for steam expansion and condensation, and separate the cooling liquid and steam in the auxiliary water tank to eliminate the gas in the cooling liquid and eliminate the air resistance of the cooling liquid. 2. Use the high static pressure of the expansion tank to balance part or all of the water pressure, eliminate the pressure and corrosion on the water pump, and stabilize the water pressure. [0003] Such as figure 1 As shown, the automobile cooling system is mainly composed of an engine 1, a radiator 2,...
