Fuel heater of engine

Abstract

A fuel heater of an engine belongs to an explosive motor. A water inlet pipe is arranged between a triple regulating valve and a fuel heater shell; an engine hot water discharging pipe and an engine hot water input pipe are arranged on the triple regulating valve; a valve core which is provided with a water outlet and a water inlet is arranged in the cavity of the triple regulating valve; a regulating pull rod sleeved with a spring is connected on the valve core; a hot fuel outlet pipe, a cold fuel input pipe and a return pipe are fixedly arranged on the fuel heater shell; an involute helix tube is arranged in the fuel heater shell; a temperature sensor is arranged on the hot fuel outlet pipe; and a digit display temperature meter is communicated with the temperature sensor. The heater of the invention has simple structure, is conveniently assembled, operated and used, has reliable operation, has good preheating effect for diesel oil and high quality, and is in favor of fully pulverizing and burning fuel, promoting the dynamic performance of engine, decreasing fuel consumption and use cost, prolonging the service life of engine and decreasing environmental pollution.

Description

technical field [0001] The invention belongs to an internal combustion engine, and mainly relates to a fuel oil heating assembly on an internal combustion engine using diesel as fuel. Background technique [0002] Scientific research and practice have proved that diesel used as fuel for internal combustion engines has the best atomization state in the range of 55°C-65°C, which not only burns fully, but also greatly improves engine working efficiency, reduces exhaust emission pollution to the environment, and reduces fuel consumption. Consumption, and it is beneficial to start the diesel engine under low temperature conditions, avoiding the failure of the flameout due to the freezing of the oil pipeline. But so far, the way to solve and overcome the above problems is still to use different oil grades of diesel oil in different seasons and different temperature environments, that is, to use high-grade diesel oil with high price in low temperature seasons, which will not only g...

AI Technical Summary

Problems solved by technology

[0005] The invention has the advantages of simple structure, easy installation and operation, reliable operation, accurate control of the temperature of the preheated diesel oil within the temperature range of the best atomization state, and is conducive to the full combustion of the engine, which not only improves the engine power, but also reduces exhaust emissions Pollution to the environment, reducing fuel consumption costs, prolonging the service life of the engine, and completely solving the difficulty of starting the diesel engine in winter and the freezing and flameout of the diesel pipeline during operation, and can also burn and use low-grade diesel oil, which expands the use of diesel engines with different grades of diesel Use range, reduce use cost, high efficiency, energy saving, environmental protection, in line with the national policy requirements on energy saving and environmental protection
