Inductive heating device for high-pressure oil supply path of crude oil engine

Abstract

The invention provides an inductive heating device for a high-pressure oil supply path of a crude oil engine. The inductive heating device comprises a plurality of inductive heating casing pipes and aheating controller. Each inductive heating casing pipe comprises a protective sleeve, a plastic framework and a spiral induction coil, wherein the spiral induction coil is packed in the plastic framework, and the plastic framework is sleeved with the protective sleeve so that an integral structure can be formed. The heating controller is arranged independently. The inner hole diameter of the plastic framework adapts to the outer diameter of an oil path connector of a high-pressure co-orbital groove assembly of the crude oil engine. The spiral induction coils of the multiple inductive heatingcasing pipes are connected in series through a harness and then electrically connected with the heating controller, and the heating controller controls the inductive heating casing pipes to work or not according to the temperature condition. In the using process, the multiple inductive heating casing pipes are directly installed on the oil path connector of the high-pressure co-orbital groove assembly of the crude oil engine in a sleeving mode. According to the inductive heating device, the occupied space is small, installation and maintenance are convenient, the heating efficiency is high, cold start of the engine is achieved, and an intake heating device of the engine is omitted.

Description

technical field [0001] The invention relates to a heating device for a high-pressure fuel supply oil circuit of a vehicle diesel engine. Background technique [0002] In recent years, with the continuous development of my country's automobile industry, the continuous application of new technologies, and the implementation of National IV and National V standards, the country has become more and more strict on diesel engine exhaust emissions, requiring fuel combustion to be as full as possible. Diesel oil in winter is easy to wax, which makes the oil circuit blocked and the fuel supply is not smooth, so it is difficult to start the engine. In order to solve the problem of starting the diesel engine at low temperature, most manufacturers mainly install an air intake heating device at the air intake of the diesel engine. There are data Indicates that the intake air heater has the following problems: [0003] 1. The heated air reduces the actual oxygen supply into the combustion c...

[0002] In recent years, with the continuous development of my country's automobile industry, the continuous application of new technologies, and the implementation of National IV and National V standards, the country has become more and more strict on diesel engine exhaust emissions, requiring fuel combustion to be as full as possible. Diesel oil in winter is easy to wax, which makes the oil circuit blocked and the fuel supply is not smooth, so it is difficult to start the engine. In order to solve the problem of starting the diesel engine at low temperature, most manufacturers mainly install an air intake heating device at the air intake of the diesel engine. There are data Indicates that the intake air heater has the following problems:

[0004] 2. Increasing the intake air temperature will increase the harmful components of the exhaust gas, which is not conducive to the environmental protection requirements of the car;

[0005] 3. Because the electric heater arranged in the air intake channel by the intake heating starter occupies the precious area of ​​the intake channel, according to calculations, the electric heater occupies about 10% of the air intake area, reducing the effective intake area and destroying the intake area. Air fluency reduces combustion efficiency;

[0006] 4. Once the electric heater cannot be cut off in time, the hot surface temperature will threaten the safety of the engine and the whole vehicle
