Anti-freezing and oil-saving air cooling device for single-cylinder diesel engine

Abstract

The invention discloses an anti-freezing and oil-saving air cooling device for a single-cylinder diesel engine. By the adoption of the air cooling device for the diesel engine, a water pump circulating system can be eliminated, the efficiency of the diesel engine is improved, the service life of the diesel engine is prolonged, the anti-freezing function is achieved, water in a water tank is prevented from boiling, oil is saved, air pollution is reduced, and environmental friendliness is achieved. The anti-freezing and oil-saving air cooling device for the single-cylinder diesel engine is characterized in that groove-shaped fan blades are arranged in three big holes in a hub, the groove-shaped fan blades are provided with installation plates which are fixed to the hub, an air outlet of an inner air ring fixed to an engine body corresponds to an air cooling channel outside the circumference of a fly wheel, a cooling base plate of the air cooling channel is fixed to the side face of a water tank, and lower ports of multiple air cooling pipes in the water tank face the air outlet. According to the anti-freezing and oil-saving air cooling device for the single-cylinder diesel engine, a circulating pump adopting a water pump for forced circulation, a triangular belt, an independent fan, a radiator, associated pipelines and accessories can be eliminated, the air cooling device can be used continuously round the clock, the temperature of the water tank can be controlled to be within the normal range, and the diesel engine can be made to work in the optimum state all the time; the air cooling device is novel in design, simple in structure, low in cost, durable and particularly suitable for 13kw-17kw single-cylinders in the north of China.

Description

technical field [0001] The invention relates to an air-cooling device for a diesel engine, in particular to an antifreeze and fuel-saving air-cooled single-cylinder diesel engine that eliminates the water pump circulation system, improves the efficiency and life of the diesel engine, prevents freezing, prevents boiling of the waterproof tank, saves fuel, reduces air pollution, and is environmentally friendly. device, Background technique [0002] At present, 13-17kw single-cylinder diesel engines are widely used in tractors, agricultural vehicles and various agricultural power machinery in rural areas of my country; Radiator, and its auxiliary pipelines, etc., the above-mentioned single-cylinder diesel engine has the following defects in the use practice in the rural areas of Northeast my country: [0003] 1. When the temperature is high in summer, the cooling is insufficient, and the water temperature of the water tank often exceeds 100°C. The boiling water can splash and h...

AI Technical Summary

Problems solved by technology

[0003] 1. When the temperature is high in summer, the cooling is insufficient, and the water temperature of the water tank often exceeds 100°C. The boiling water can splash and hurt people or cause circuit failure; the cooling water evaporates a lot, and water needs to be added frequently, which will delay work or cause water shortage in the water tank. into an accident

[0004] 2. When the temperature of the water tank exceeds 100°C in summer, the diesel engine will not work normally; it will reduce the output power, increase the fuel consumption rate, and increase the oil temperature, which will reduce the overall efficiency of the diesel engine; the cooling water temperature is too high, causing the diesel engine to burn If it is not normal, it will make its power and economy worse, and the key components will accelerate wear due to poor lubrication or high temperature will cause the oil to become thinner, deteriorate, and zoom, resulting in various failures of the diesel engine and a decrease in service life

[0005] 3. If the cooling water temperature is too high, it will cause incomplete combustion of diesel oil, black smoke from the exhaust, and pollute the atmospheric environment, which is not conducive to environmental protection.
