Embodiment Construction

[0011] figure 1 Shown, a compression ignition engine. The compression ignition engine structure mainly includes: crankcase 1, crankshaft 2, crank 3, piston 4, cylinder 5, cylinder head 6, intake valve 7, exhaust valve 8, exhaust pipe 9, air filter 10, supercharger Fan 11, cylinder air-cooled coil 12, fuel tank 13, fuel pump 14. The crankcase 1 is lubricated with organic oil, and the cylinder 5 is covered with a cylinder air-cooled coil 12. After passing through the air filter 10, the air is blown into the cylinder air-cooling coil 12 by the booster fan 11, and then enters the intake pipe after passing through an electromagnetic air valve 27 and a tee, and finally enters the cylinder 5 through the opened intake valve 7. The compressed air extruded by the air compressor 21 enters the compressed air storage tank 23 after passing through the check valve 22 . The compressed air storage tank 23 is equipped with a pressure sensor. The compressed air coming out from the compressed...

Abstract

The invention discloses a compression ignition engine and a low-pressure low-temperature ignition and exhaust pollution elimination method. The compressed air in a compressed air package is heated through a compressed air electric heater or the waste heat exhausted from the engine, the heated compressed air is fed into a cylinder in the stating process of the engine or the air suction stroke during acceleration, and accordingly the temperature of the compressed air in the cylinder at the beginning of the power stroke is improved and accordingly the injected vaporized fuel is easy to ignite. The lower concentration of injected vaporized fuel can be ignited under the 400 DEG C and can be fully burnt due to a honeycomb three-way catalytic alloy net which is arranged in the cylinder. The hot air inside a cylinder air-cooled coil pipe can be fed into the cylinder through a booster fan in the process of normal operation of the engine. The high-temperature fuel heated through a liquid fuel electric heater or a liquid fuel exhaust heater enters a vaporizing chamber to be vaporized and the vaporized fuel in the vaporizing chamber continues to be heated through a vaporized fuel infrared electric light wave heater or a vaporized fuel exhaust heater. Accordingly, the compression ratio can be reduced.

Description

Technical field: [0001] The invention relates to a compression ignition engine and a low-pressure low-temperature ignition and a method for eliminating tail gas pollution. Background technique: [0002] At present, many buses are more energy-saving and environment-friendly gas buses. However, the cost of gas is high and it is difficult to refuel; the mileage of a car driven by a tank of gas is far less than that of a car driven by a tank of fuel, and the driving force of a fuel car is greater. Fuel-fueled buses are very polluting. Every time they stop at a station and then drive away, a string of black smoke will come out from the exhaust pipe, and the passengers waiting for the bus at the station will only cover their noses. In order to fully burn the fuel, some people use stratified combustion, gasoline direct injection, intake heating and other technologies to modify the engine. Diesel stratified combustion and gasoline direct injection both divide the fuel into several...
