Description of the Invention: [Technical Field] The present invention relates to an ignition system for a gasoline engine, and more particularly to an engine ignition system that completely burns gasoline and has low air pollution. [Prior Art] According to i, the general fuel vehicles used in general vehicles (steam and locomotive) are mainly diesel and gasoline engines. The diesel fuel system uses two temperatures of compressed air to make the spray. The diesel of humans is naturally burning, and the gasoline engine relies on high-voltage electric sparks to ignite the mixed steam, so that the engine can run; that is, when the gasoline engine is in operation, it is skipped by the high-voltage electricity of thousands of volts. The electrode gap generates a spark, and the compressed mixed steam is ignited by the spark to form a flame core, and then rapidly expands to the entire portion to generate rapid combustion, so that the gas rapidly expands and pushes the piston to generate power. _ 'The performance of gas-fired enthalpy is mainly affected by the ignition system. For example, if the spark is weak or the ignition time is not accurate, the engine will be weak, consume fuel, knock, and will be discharged most. #废气; Therefore, the modern > fly, locomotive discussion also focuses on the improvement of the ignition system, in order to meet the requirements of harm and fuel economy; in terms of the complete operation of the crankshaft of a cylinder, ^, the ignition time will be different A picture shows the efficiency shift, although ^/ by the engine in which each cylinder is located 1 〇 after the top dead center of the crankshaft. When the maximum pressure is generated in the left and right (efficiency zone), the engine can get the maximum power, and the engine speed is maintained, but the speed is maintained when the crankshaft is in the ignition zone of the efficiency zone 1302963. However, when the vehicle speed or deceleration is limited, the system utilizes Ignition in the efficiency zone but discontinuous, with different or the same time interval (time = interval) ignition, although it can also achieve the function of limiting speed or deceleration, but it is easy to make the fuel burn incomplete, and as the exhaust gas flows out, More fuel consumption can even create an explosion hazard. SUMMARY OF THE INVENTION In view of the present invention, the present invention utilizes continuous ignition or non-equal time mode = fire and controls the ignition position of the engine in the non-efficiency zone, so that the vehicle can completely burn the fuel and reach the speed limit. The effect; especially the basin, although the bow I engine needs to accelerate, then the engine is changed in the non-efficiency zone to change the ignition, and the engine output speed and torque are increased to meet the two high-speed driving or high torque. Power demand. [Embodiment] Mode = The member of the review committee is aware of the composition of the present invention, and the implementation of the "Improved iron engine ignition system" is based on the engine operating load and other fields and ignition positions, meaning (four) with continuous ignition or non-decisive The ignition position in the non-efficiency zone 'causes the fruit. Lu: D, can make the fuel completely burn and achieve the speed limit effect ^ = ^ When the engine needs to accelerate, then the engine is fully ignited in the non-efficiency zone: the ignition zone ignition 'up The output speed and torque of the engine to meet the power demand of the vehicle to drive higher torque. 1302963 When the time is implemented, the vehicle speed can be used as the preset value for setting the engine to change the ignition position, or the mixed steam can be used as the preset value for setting the engine to change the ignition position, and even the vehicle speed can be used at the same time. The mixing amount is used as a preset value for setting the engine to change the ignition position, or the digital device is used to change the preset value of the ignition position; in other words, the engine continues to ignite in the efficiency zone while the vehicle is running, so that the engine is maximally powered and the engine speed is increased. In order to increase the speed of the vehicle, but if the vehicle wants to limit its speed or reduce the speed, use the above various changes to the preset value of the ignition position to change the ignition position of the engine in the non-efficiency zone, and to continue ignition or non-efficiency. Iso-distance (different time intervals) mode is used to ignite in the non-efficiency zone, so that the engine's power is gradually reduced, thereby achieving the function of limiting the speed of the vehicle and reducing the speed, and allowing the fuel to be completely burned-burned without The danger of explosion. Furthermore, when the vehicle is driven to accelerate or the vehicle is ramping up and needs to continue to step on the throttle to accelerate the engine, the speed of the vehicle and the amount of mixed steam will increase, when one of the two conditions exceeds the preset value. The entire ignition system changes the engine's ignition in the inefficiency zone to ignite in the efficiency zone, increasing the engine's output speed and torque to meet the high-speed driving or high-torque power requirements. As described above, the present invention provides a preferred and feasible ignition system for a gasoline engine, and an application for an invention patent is provided according to the law; however, the above embodiments and drawings are preferred embodiments of the present invention, and are not The present invention is intended to be similar to the structures, devices, features, and the like of the present invention, and should be within the scope of the present invention and the scope of the claims. 1302963 [Simple description of the diagram] The first diagram is an efficiency diagram showing the single cylinder as a function of ignition timing.
