Energy-saving preheating system of vehicular engine

Abstract

The invention discloses an energy-saving preheating system of a vehicular engine. The energy-saving preheating system of the vehicular engine comprises a box, a heat preservation layer is arranged inside a shell of the box, a gas inlet tube is arranged in the middle of the top end of the box, a gas outlet tube is arranged in the middle of the bottom end of the box, a heat energy recovering device and a waste heat exchanger are arranged in the box, the heat energy recovering device is composed of a plurality of inlet gas collecting tubes and a plurality of outlet gas collecting tubes, and a plurality of branch tubes are arranged among the inlet gas collecting tubes and the outlet gas collecting tubes. The energy-saving preheating system has the advantages that a structure is compact, recovering, storing and converting of tail gas heat of a vehicle are integrated in the box which is small in occupied space, usage is facilitated since the energy-saving preheating system can be used by means of being connected with a vehicular exhaust tube which is changed, and the energy-saving preheating system mounted at the position of vehicular exhaust tube is small in resistance and has no effect on normal work of the engine.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an energy-saving preheating system for a vehicle engine with compact space and reasonable arrangement of piping systems. Background technique [0002] With the rapid development of the automobile industry, automobiles can be seen everywhere. Since it has made great contributions to people's life and social development, it has been a big concern for people to start automobiles in cold conditions, especially in the north. In winter, it is difficult to start the car. In order to increase the temperature of the antifreeze, it is generally necessary to bake the oil pan of the car with a blowtorch before the cold start. This method has a high risk factor and is easy to deteriorate the oil. Roasting is even more undesirable, the effect is not good, time-consuming and labor-intensive, and it is prone to fire or damage to the machine, causing unnecessary losses. It can be solved by heating wit...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an energy-saving preheating system for vehicle engines, which solves the need for preheating of large and medium-sized truck engines when starting at low temperature. Traditional preheaters need to use commercial power, and the used The space position is restricted, and electric energy cannot be saved, and the waste heat of automobile exhaust cannot be recycled. This equipment only needs to slightly modify the exhaust pipe of the locomotive, and the waste heat discharged by itself can solve the above problems
