Non-air throttle engine and method for controlling power and maintaining constant pressure and contractive pressure and evading explosion

Abstract

A combustion volume technique and a control inflation quantity technique can be synchronously executed and controlled so as to gain a most suitable compression pressure which aims at avoiding detonation, optimum operation and fuel adaptation under full working condition by an upper and lower cylinder moving device which is controlled by a servo system, a combination camshaft device, a built-in device, a special electricity removal excitation valve control system, and a compression pressure arrangement and adjustment system which is based on the previous devices. The best working point of an engine is elongated to the line of all power lines of full working conditions, and the engine always keeps the best working state under the full working condition, has more powerful power and saves the energy and protects the environment more. By adopting the technique, the invention gains a method which leads a reciprocating engine to generate an expiration (aspiration) stroke and controls the power thereout. The invention provides the method which leads the engine to keep constant compression pressure under full working condition and restrains and avoids the occurrence of detonation and deflagration by reducing the compression pressure.

Description

Technical field: [0001] This invention relates to reciprocating engines. Background technique: [0002] I have an original (invention) patent (patent number: 200710057139.X) that I have applied for. This patent uses the mechanical displacement of the mechanical controller (accelerator pedal) as the parent command, and adopts a synchronous linkage positioning displacement device and an upper and lower cylinder moving device. , Combined camshaft mechanism, constant air-fuel ratio oil supply system four independent technologies, and the engine implementing the four inventions of the patent at the same time has five strokes of suction, exhalation (exhalation), compression, explosion, and exhaust. The combined camshaft mechanism in this patent has an anti-rotational displacement connector, wherein the actuator drives the cam mandrel, and the cam mandrel drives the cam lobe, which can cause the intake valve to be closed late at the end of the suction stroke, and the piston goes up...

Problems solved by technology

[0003] Furthermore, the density of the air to a certain extent (related to temperature) can be reflected by the compression pressure value, the compression pressure is crucial to the performance of the engine, and the different (ideal) compression pressures of various working conditions are the efforts to improve the performance of the engine Direction, the single methods currently used such as variable compression ratio technology, variable gas distribution technology, and throttle control are not effective in adjusting the compression pressure, especially in the face of various working conditions. This single method cannot obtain For the problem of different (ideal) compression pressures in various working conditions, the engine can only obtain a point of the best working condition, and cannot obtain the line to maintain the best working condition under various working conditions.

[0004] In addition, the current new engine runs under high compression ratio (high compression pressure) conditions, and the technical measures and methods to solve the problem of deflagration are mainly solved by the electronic control system adjusting the ignition angle through the actuator, such as patent; 'CN: 99800428.6 ,, 'DE3420465C2', etc., this method of adjusting the ignition angle is at the expense of fuel consumption and power, because the best ignition angle can only get the best results when it is related to the speed and load. This measure and method does not It is beneficial to energy saving, torque and emission. The occurrence of deflagration is conditioned by pressure, temperature and fuel characteristics. Adjusting the ignition angle is not the best solution to the problem.
