Problems solved by technology

[0029] 1. At present, there is no optical engine that can replace different engine combustion chambers and can use laser diagnosis methods to study the combustion process in the cylinder
[0030] 2. At present, there is no such optical engine, which can achieve reasonable adjustment of the EGR amount through the combination of different phase and lift strategies of the fully variable valve train, and use various optical means to analyze and study to achieve control Ignition start point and distribution law of in-cylinder temperature, velocity, concentration and pressure field, etc., which are resolved by time and space, so as to realize CAI / HCCI combustion and expand its working area

Embodiment Construction

[0044] Referring to the embodiments shown in the accompanying drawings, the specific content and implementation of the present invention will be further described.

[0045] In the optical engine of the present invention, a ring gasket is arranged between the lengthened cylinder body and the cylinder head, and four laser transparent windows that can enter the laser beam are installed on the positions perpendicular to each other in the radial direction of the ring gasket; The upper part is provided with a combustion chamber that is as large as possible and has a certain shape, and there is a transparent window for the combustion chamber that can be used to observe the movement of the working fluid and the combustion process; The reflector on the body is at an angle of 45° to the piston axis; there is a cooling water jacket in the extended cylinder body, and hot water is supplied to the cooling water jacket through a temperature-controllable circulating cooling water tank; A fuel...

Abstract

The invention relates to an optical generator for providing different combustion modes during combusting different fuels in different combustion chambers. The optical generator is characterized in that an elongated cylinder (302), an elongated cylinder sleeve (303), an elongated piston (203) and a circular gasket (101) are additionally mounted between an original cylinder (305) and a cylinder cover (301), a valve timing mechanism (308) is assembled on the cylinder cover (301), a circular aluminum alloy briquetting (201) and a transparent combustion chamber window (202) are mounted at the upper part of the elongated piston (203), a reflector (304) at 45 degrees with the axis of the piston is obliquely arranged at the lower part of the elongated piston (203), an angle scaler (5) is arranged on a generator crankshaft (307), an air cylinder pressure quartz sensor (7) is assembled on the cylinder cover (301), and a valve lift-range inductor sensor (9) is mounted on the valve timing mechanism (308).

Description

technical field [0001] The invention relates to an automobile or a power machine engine, in particular to an optical engine. Background technique [0002] In recent years, under the situation of depletion of petroleum resources and stricter automobile emission regulations, the urgency of reducing automobile emissions and improving automobile fuel economy is particularly prominent. Since the fuel economy of the gasoline engine is worse than that of the diesel engine, it is more urgent to reduce the fuel consumption of the gasoline engine. [0003] Compared with the traditional combustion mode, the latest Controlled Auto-Ignition Ignition (CAI) or Homogeneous Charge Compression Ignition (HCCI) has the advantages and potential of extremely low NOx, CO emissions and improved fuel economy, and is being internationally recognized. The internal combustion engine industry is widely valued and is considered to be one of the most attractive gasoline engine technologies in the future....
