Description

technical field [0001] The invention relates to the technical field of engines, in particular to a high-torque output fuel-saving and energy-saving piston engine. Background technique [0002] With the development of engine technology, there are more and more engine models. The common ones are two-stroke engine, four-stroke engine, diesel engine and gasoline engine, etc., but each has its own shortcomings, as shown below. [0003] Two-stroke engine: 1. Insufficient air intake in the cylinder volume. First, the exhaust gas in the cylinder starts to inhale before it is completely discharged. Secondly, part of the fresh air in the inhalation leaks part when the exhaust gas is discharged; 2. When the exhaust gas is exhausted, the Part of the inhaled fresh air and fuel leak, and the insufficient inhaled fresh air causes incomplete combustion and high fuel consumption; 3. The service life of the engine is relatively short due to poor cylinder lubrication and lubricating oil leakag...

AI Technical Summary

Problems solved by technology

[0003] Two-stroke engine: 1. Insufficient air intake in the cylinder volume. First, the exhaust gas in the cylinder starts to inhale before it is completely discharged. Secondly, part of the fresh air in the inhalation leaks part when the exhaust gas is discharged; 2. When the exhaust gas is exhausted, the Part of the inhaled fresh air and fuel leak, and the insufficient inhaled fresh air causes incomplete combustion and high fuel consumption; 3. The service life of the engine is relatively short due to poor cylinder lubrication and lubricating oil leakage

[0004] Four-stroke engine: 1. Every time the output shaft rotates 2 times, only half a circle does work, and the energy density is small. In the case of heavy loads, such as when a car is started or a ship, etc., when the inertia of the flywheel cannot overcome these resistances, the engine will fail. 2. The engine is inherent and cannot be changed. When the piston is at the top dead center or just past the top dead center, when the piston burns and expands to do work, the torque is zero or very small, causing a large part of the impact force and impact energy to be wasted in the rotation On the shaft, the output torque and kinetic energy are very small. As the crank is rotated away from the line between the upper and lower dead centers, the torque will become larger and larger, and it will be the largest when it rotates to 90 degrees. But at this time, the piston has moved to the middle of the cylinder, and the volume of the cylinder increases. , the gas density and temperature and pressure are greatly reduced, and the air pressure at this time is about 5 atmospheres. Compared with about 40 atmospheres at the moment of ignition and expansion at the top dead center, the torque output loss is too much

[0005] In addition, the compression ignition speed of the diesel engine is relatively low, and the heat energy recovery is small; the ignition of the gasoline engine is affected by the strict oil-gas ratio, and the fuel consumption is high
