Device for increasing fuel oil utilization rate and improving performance of diesel engine

Abstract

The invention relates to a device for increasing the fuel oil utilization rate and improving the performance of a diesel engine. According to the method, by the adoption of an air compressor and an air-heated air box, nature energy waste gas is converted into kinetic energy, a modulator is conducted ahead when oil is supplied, a valve rod and a valve guide pipe are sealed, and double tension springs are adopted for speed adjustment; a starting fuel enrichment component is arranged on a fuel quantity limitation screw, emission of carbon monoxide is reduced, the gas distribution time is adjusted, an electric ignition system is arranged, and the performance of the machine is improved; and the device has the beneficial effects that the fuel utilization rate is as high as 60%, the starting is easy, the size is small, the motor is large, the rotating speed range is large, a high-rotating-speed machine can operate at a low rotating speed for a long time, the adaptability is high, lubricatingoil is saved, the carbonization speed of the lubricating oil is lowered, the rotating speed is high, the energy consumption is low, and the structure is simple; and the performance is good, the investment cost is low, and the adjustability of various scheme methods is high.

Description

technical field [0001] The invention relates to a device for improving the fuel utilization rate and performance of a diesel engine. Background technique [0002] With the rapid development of rural areas and mechanization, diesel engines are commonly used power equipment in agricultural production. However, the common problems are: [0003] 1. The fuel utilization rate is low, the emission is large, and a large amount of heat energy is wasted. 2. Some diesel engines are energy-saving, and the fuel supply time is advanced, which makes it difficult to start and the machine cannot run at a low speed, causing inconvenience to the tractor driver and causing personal safety hazards. Multi-air direct injection has high requirements on fuel quality and is not suitable for rural areas. 3. Exhaust gas enters the valve cover from the gap between the valve guide and the valve stem, causing carbonization of the lubricating oil and reducing the service life of the valve stem and guide....

AI Technical Summary

Problems solved by technology

[0003] 1. The utilization rate of fuel is low, the emission is large, and a large amount of heat energy is wasted

2. Some diesel engines are energy-saving, and the oil supply time is advanced, which makes it difficult to start and the machine cannot run at low speed, causing inconvenience to the tractor driver and causing personal safety hazards

Multi-space direct injection has high requirements on fuel quality and is not suitable for rural areas

3. Exhaust gas enters the valve chamber cover from the gap between the valve guide and the valve stem, causing carbonization of the lubricating oil and reducing the life of the valve stem and guide

Lubricating oil reaches the cylinder from the gap between the intake valve stem and the valve guide, causing oil burning

4. Diesel engines do not have the advantages of small size, high horsepower, and large speed range

5. The air in the cylinder of the diesel engine is inhaled, and the compression ratio is low at high speed

6. The oil supply time cannot change with the speed

7. Diesel air-cooled cooling machine, water pump, long-term low load, low body temperature, is not conducive to fuel combustion, and consumes power
