Embodiment Construction
[0017] Below in conjunction with accompanying drawing and specific embodiment the present invention will be further described:
[0018] When the rotational speed n of the rotary engine changes from n=0 to n≠0, it is the start-up phase, and only the ignition mode of the cylinder spark plug (7) is used at this time; during the start-up phase, the electronic control unit ECU ( 13) Send the throttle opening signal a to open the throttle valve (S1), and the fresh charge enters the cylinder through the air intake passage through the air filter (6) and the throttle valve (S1) in sequence; gasoline fuel passes through the gasoline tank (1) in sequence , gasoline filter (2), oil pump (3) and gasoline mass flow regulator (4) are sent to the gasoline nozzle (5), and the electronic control unit ECU (13) sends a gasoline injection signal b according to the gasoline injection timing of the rotary engine engine b , gasoline fuel is injected into the intake port, and gasoline is mixed with fr...

The invention designs an ignition rotor machine with opposed cylinder covers and a control method for the ignition rotor machine, and relates to an ignition and combustion control technology for spark plugs of opposed cylinder covers of a rotor machine. A first cylinder cover spark plug (9) and a second cylinder cover spark plug (12) are additionally arranged on a front cylinder cover and a rear cylinder cover of the rotor machine separately, so that rapid and sufficient combustion of fuel in a combustion chamber is achieved through composite flames; and the output torque of the rotor machine and the cyclic variation coefficient of in-cylinder pressure are controlled in real time through an electronic control unit ECU (13), so that stable operation of the rotor machine is ensured, meanwhile, the fuel economy of the rotor machine is effectively improved, exhaust gas emission is reduced, and the application of the rotor machine with rapid and sufficient fuel combustion and low fuel consumption is achieved.
Description
technical field [0001] The invention designs a cylinder head opposed ignition rotor machine and a control method thereof, specifically relates to a rotor machine cylinder head opposed spark plug ignition combustion control method, which belongs to the field of internal combustion engines. Background technique [0002] With the increase of the number of automobiles in our country year by year, the environmental pollution caused by automobile emissions has increasingly become the focus of attention. At present, reducing the fuel consumption and emissions of internal combustion engines is still the mainstream research direction in the field of internal combustion engines. [0003] Compared with traditional internal combustion engines, rotary engines have the advantages of small size, light weight, simple structure, and large power-to-weight ratio. Researchers from many countries in the world believe that rotary engines are used in hybrid vehicle range extenders, small electric e...
