Abstract

The invention relates to a diesel heating device for a vehicle. The diesel heating device for the vehicle is used for heating diesel by utilizing heat of tail gas of the vehicle, and is formed by connecting a tail gas heat collecting and exchanging box with a tail gas flow control box, wherein the tail gas heat collecting and exchanging box is provided with a plurality of concentric radial heat pipes; and the tail gas flow control box is provided with two guide flow control plates which are symmetrically arranged, have a flow guiding effect and effects of a valve, and can relatively rotate synchronously within a range of 60 degrees. An exhaust channel port of the diesel heating device can be directly connected with an exhaust channel of an engine of the vehicle, can circularly rotate around the center of the exhaust channel of the engine to be arranged in optional directions, and is connected to a fuel supply system of the engine through a fuel tube joint, when the engine works, fuel can be heated by the heat of tail gas discharged from the engine, and diesel is sufficiently isolated from the tail gas of the exhaust channel in the structure. The flowing direction and the flow of the tail gas are regulated and controlled in a stepless manner by operating an adjusting plate driving mechanism, and during running of the diesel heating device, the temperature of the fuel, input of the device or running stop are controlled. The safety of the diesel heating device is improved, and heating temperature and heating time are controllable. The diesel heating device for the vehicle can be a normal facility of the vehicle, and is not required to be detached in summers, and by the diesel heating device, the vehicle can continue using low-grade diesel in winters.

Description

technical field

[0001] This is a vehicle diesel heating device that is installed on a vehicle powered by a diesel engine and uses the heat in the high-temperature exhaust gas discharged from the diesel engine to heat and increase the temperature of the vehicle's fuel-diesel. More specifically, it relates to the improvement of a vehicle diesel heating device. Background technique

[0002] The transportation sector uses a large number of vehicles fueled by diesel oil. With the change of seasons and temperatures, in order to ensure the normal operation of the engine, it is necessary to constantly replace the grade of diesel oil. Under low temperature conditions, Diesel vehicles use low-grade diesel to replace high-grade diesel, that is, to expand the scope of use of low-grade diesel. In today's energy shortage and high oil prices, its far-reaching energy-saving significance and economic benefits are immeasurable.

[0003] To allow the use of low-grade diesel in winter, the ea...
